installation, operation, or maintenance
information which is important but not
hazard-related.

0.2 SAFETY PRECAUTIONS

SAFETY PRECAUTIONS
BEFORE PROCEEDING, READ CAREFULLY BEFORE INSTALLING THE
COMPRESSOR OR PERFORMING ANY MAINTENANCE
WARNING
COMPRESSED AIR AND ELECTRICITY
ARE DANGEROUS.
BEFORE DOING ANY WORK ON THIS
UNIT, BE SURE THE ELECTRICAL SUPPLY
HAS BEEN CUT OFF–LOCKED & TAGGED
AND THE ENTIRE COMPRESSOR SYSTEM
HAS BEEN VENTED OF ALL PRESSURE.
1. Do not remove the covers, loosen or
remove any fittings, connections or
devices when this unit is in operation. Hot
liquid and air under pressure that are
contained within this unit can cause
severe injury or death.
2. The compressor has
high and
dangerous voltage in the motor starter and
control box. All installations must be in
accordance with recognized electrical
codes. Before working on the electrical
system, be sure to remove voltage from
the system by use
of a manualdisconnect-switch. A circuit breaker or
fuse safety switch must be provided in the
electrical supply line leading to the
compressor.
Those responsible for installation of this
equipment must provide suitable grounds,
maintenance clearance and lightning
arrestors for all electrical components as
stipulated in O.S.H.A. 1910.308 through
1910.329.

3. Do not operate the compressor at higher
discharge pressure than those specified
on the Compressor Nameplate or motor
overload will occur. This condition will
result in compressor motor shutdown.
4. Use only safety solvent for cleaning the
compressor and auxiliary equipment.
5. Install a manual shut off valve (isolation
type) in the discharge line. When a safety
valve is installed between the isolation
valve and the compressor, it must have
sufficient capacity to relieve the full
capacity of the compressor(s).
6. Whenever pressure is released through
the pressure relief valve, it is due to
excessive pressure in the system. The
cause for the excessive pressure should
be investigated immediately.
7. Before doing any mechanical work on
the compressor:
a.) Shut the unit down.
b.) Electrically isolate the compressor by
use of the manual disconnect switch in the
power line to the unit. Lock and tag the
switch so that it cannot be operated.

8. There can be adverse effects if
compressor lubricants are allowed to enter
plant air systems.
Air line separators, properly selected and
installed, will minimize any liquid carryover.
The use of plastic bowls on line filters
without metal guards can be hazardous.
From a safety standpoint, metal bowls
should be used on any pressurized
system. Review of your plant air line
system is recommended.
9. When a receiver is installed, it is
recommended that occupational safety
and health standards as covered in the
Federal Register, Volume 36, number 105,
part 11, paragraph 1910.169 be adhered to
in the installation and maintenance of this
receiver.
10. Before starting the compressor, its
maintenance instructions should be
thoroughly read and understood.
11. After maintenance functions are
completed, covers and guards must be
replaced.

c.) Vent pressure from the compressor and
isolate the unit from any other source of
air.

SAFETY SHUTDOWN
CHECK HIGH AIR TEMPERATURE
There is a high discharge air temperature shutdown function built into the Intellisys on each compressor. It is factory pre-set
at 228°F (109°C). This function should be checked at regular intervals for proper operation, once a month is recommended.
The procedure is:
1.
2.

Block off the cooling air discharge.
The compressor discharge temperature will rise at a rapid rate. Shutdown should occur when the discharge
temperature reaches the pre-set maximum discharge air temperature setting of the Intellisys. The display should
indicate “HIGH AIREND DISCH TEMP” and flash “ALARM”.

The actual temperature at which shutdown occurs should be recorded for comparison to the Intellisys set point and with
similar future test results.

WARNING
Failure to adhere to these recommendations can result in mechanical failure, property damage and serious injury or death.
All air and water inlet, and air and water discharge pipework to and from the inlet and discharge port connections must take
into account vibration, pulsations, temperature, maximum pressure applied, corrosion and chemical resistance. In addition, it
should be noted that lubricated compressors will discharge some oil into the air stream; therefore, compatibility between
discharge piping, system accessories and software must be assured.
For the foregoing reasons, the use of plastic piping, soldered copper fittings and rubber hose as discharge piping is not
recommended. In addition, flexible joints and/or flex lines can only be considered for such purposes if their specifications fit
the operating parameters of the system.
It is the responsibility of the installer and owner to provide the appropriate service pipework to and from the machine.

WARNING
“Ingersoll-Rand air compressors are not designed, intended, or approved for breathing air. Ingersoll-Rand does not approve
specialized equipment for breathing air application and assumes no responsibility or liability for compressors used for

1.2 UNPACKING AND HANDLING
The compressor package has been mounted on a base
which provides for forklifting between the two side
channels to facilitate handling during shipment. Care in
positioning the forklifts is important because the location
of the center of gravity is strongly affected by the location
of the compression module and drive motor.
Slings can be used to lift the crates, but spreader bars
must be used to prevent the slings from exerting a force
against the sides of the crates.
1.3 TOOLS
Remove compressor unit from wooden skid. A crowbar
and hammer will be needed.

IMPORTANT
Before starting this air compressor unit, the
shipping brace(s) must be removed.
Save the brace(s) for future use.
See tag in unit.

2.0 INSTALLATION
2.1 VENTILATION
Oil flooded rotary air compressors produce large
amounts of heat. Because of this large heat production,
the compressor must be placed in a room with adequate
ventilation.
If heated air from the compressor exhaust is allowed to
recirculate back to the compressor, the compressor will
overheat and shut down. This heat must be exhausted
from the room. You should take this into consideration
when you decide where to place the compressor within
your plant. Consider that the required maintenance
clearance is 3 ft (.9 m) all around the compressor.
However 42” (1.06m), or minimum required by latest NEC
or applicable local codes, must be maintained in front of
control panel.
Ambient temperatures higher than 115°F (46°C)
should be avoided as well as areas of high humidity.
Consider also the environment surrounding or near
the compressor. The area selected for the location of
the compressor should be free of dust, chemicals,
metal filings, paint fumes and overspray.

2.2 FOUNDATION REQUIREMENTS
Refer to the foundation plan for the particular model
compressor to be installed. See Section 8.0.
The compressor can be installed on any level floor that is
capable of supporting it. Compressor weights are listed
on the foundation plans.
When sound transmission is of particular importance it is
often helpful to install a sheet of rubber-fabric-matting, or
cork under the compressor to reduce the possibility of
resonant sounds being transmitted or amplified through
the floor.

NOTICE
Never elevate the compressor unit
above the floor level. This may allow air
to enter the cabinet under the base.
Performance will be affected.

2.3 PIPING
The use of plastic bowls on line filters without metal
guards can be hazardous. Their safety can be affected by
either synthetic lubricants or the additives used in mineral
oil. From a safety standpoint, metal bowls should be used
on any pressurized system. Review of your plant air line
system is recommended.

WARNING
Do not use plastic pipe, soldered copper
fittings or rubber hose for discharge piping.

The built-in aftercooler reduces the discharge air
temperature well below the dew point (for most ambient
conditions), therefore, considerable water vapor is
condensed. To remove this condensation, each
compressor with built-in aftercooler is furnished with a
combination condensate separator/trap.
9

2.3 PIPING (Continued)
A dripleg assembly and isolation valve should be
mounted near the compressor discharge. A drain line
should be connected to the condensate drain in the
base.
IMPORTANT: The drain line must slope downward from
the base to work properly.
NOTE: For ease of inspection of the automatic drain trap
operation, the drain piping should include an open funnel.
It is possible that additional condensation can occur if the
downstream piping cools the air even further and low
points in the piping systems should be provided with
driplegs and traps.

DISCHARGE PIPING WITH AFTERCOOLER

IMPORTANT: Discharge piping should be at least as
large as the discharge connection at the compressor
enclosure. All piping and fittings must be suitable for the
maximum operating temperature of the unit and, at a
minimum, rated for the same pressure as the compressor
sump tank.

NOTICE
Do not use the compressor
to support the discharge pipe.
Careful review of piping size from the compressor
connection point is essential. Length of pipe, size of pipe,
number and type of fittings and valves must be
considered for optimum efficiency of your compressor.
ROTARY-RECIP IN PARALLEL

It is essential when installing a new compressor to review
the total plant air system. This is to ensure a safe and
effective total system.
200

Moisture in compressed air is responsible for costly
problems in almost every application that relies on
compressed air. Some common problems caused by
moisture are rusting and scaling in pipelines, clogging of
instruments, sticking of control valves, and freezing of
outdoor compressed air lines. Any of these could result in
partial or total plant shutdown.

160
Gallons of Water/24
hours/1000 acfm

Liquid water occurs naturally in air lines as a result of
compression. Moisture vapor in ambient air is
concentrated when pressurized and condenses when
cooled in downstream air piping.

120

DEW POINT

Compressed air dryers reduce the water vapor concentration and prevent liquid water formation in
compressed air lines. Dryers are a necessary companion
to filters, aftercoolers, and automatic drains for improving
the productivity of compressed air systems.

Two types of dryers, refrigerated or desiccant, are used
to correct moisture related problems in a compressed air
system. Refrigerated dryers are normally specified where
compressed air pressure dew points of 33°F (1°C) to
39°F (4°C) are adequate. Desiccant dryers are required
where pressure dew points must be below 33°F (1°C).

NOTE: Screw type compressors should not be installed
in air systems with reciprocating compressors without a
means of pulsation isolation, such as a common receiver
tank. We recommend both types of compressor units be
piped to a common receiver utilizing individual air lines.
When two rotary units are operated in parallel, provide an
isolation valve and drain trap for each compressor before
the common receiver.

2.4 ELECTRICAL INSTALLATION
Before proceeding further, we recommend that you
review the safety data in the front of this manual.

ROTARY TWO COMPRESSOR SYSTEM

Locate the compressor data plate on the side of the
cooler box or end of the unit.
Compressor Package Data

The data plate lists the rated operating pressure, the
maximum discharge pressure and the electric motor
characteristics and power.
Confirm that the line voltage and compressor nameplate
voltage are the same and that the standard starter box
meets the intent of NEMA 1 guidelines.
Open the starter box door. Confirm that all electrical
connections are made and tightened. Confirm that the
control transformer is wired correctly for supply voltage.
See Figure 2.4-1 on next page for typical control
transformer wiring.

2.5 OUTDOOR SHELTERED INSTALLATION
Many times a compressor must be installed outside due
to jobsite conditions or limited space within a
manufacturing facility. When this occurs there are certain
items that should be incorporated into the installation to
help ensure trouble free operation. These items have
been listed below plus Figure 2.5-1 has been included to
show a typical outdoor sheltered installation. The unit
must be purchased with the Outdoor Modification Option
to provide NEMA 4 electrics and a cabinet exhaust on
the end of the unit rather than the top to prevent recirculation of cooling air.
■

The compressor should be on a concrete pad
designed to drain water away. If the concrete pad is
sloped, then the compressor must be leveled. In order
to properly pull cooling air through the aftercooler, the
base/skid must be sealed to the concrete pad.

■

Condensate drains must never be allowed to dump on
the ground. Run to a suitable sump for future
collection and disposal or separation of lubricant and
water mixture.

■

Incoming power connections must use suitable
connectors for outdoor weather tight service.

■

A minimum of 3 ft (.9 m) clearance must be allowed
on all four sides of the unit for service access. If
possible, access by a forklift and/or an overhead beam
hoist should be kept in mind (for eventual service to
airend or motor).

■

If the area around the installation contains fine
airborne dust or lint and fibers etc., then the unit
should be purchased with the High Dust Filter Option
and TEFC motors.

■

The roof of the shelter should extend a minimum of
4 ft (1.2 m) around all sides of the compressor to prevent direct rain and snow from falling on the unit.

■

If larger debris, such as leaves or trash, are blowing in
the area, the Inlet Panel Filter Accessory should be
purchased and added to the unit (ship loose item).

■

Air-cooled machines must be arranged under the
shelter in a way that prevents air recirculation (i.e. hot
exhaust back to the package inlet).

■

Some type of protection such as a fence or security
system, should be provided to prevent unauthorized
access.

■

If the installation includes more than one compressor,
the hot air exhaust should not be directed towards the
fresh air intake of the second unit or an Air Dryer.

■

If a standard machine is to be installed outside, the
ambient temperature must never drop below 35°F
(1.7°C).

■

If ambient temperature drops below 35°F (1.7°C) to as
low as –10°F (–23°C) the unit must be supplied with
the Low Ambient Option. Installations below –10°F
(–23°C) ambient are not recommended. The Low
Ambient Option requires a separate power source to
operate internal heaters.

■

Arrange the machine with the Intellisys controller/starter enclosure facing away from the sun as
radiant heat can affect starter/lntellisys performance.
Also direct sunlight and UV rays will degrade the
membrane touch panel. This is not a warrantable
situation.

■

Power disconnect switch should be within line of sight
and in close proximity to the unit. N.E.C. and local
electrical codes must be followed when installing the
power disconnect switch.

The operator panel is divided into two areas. The
bottom row of four buttons provides direct control over
the starting, stopping, unloading and loading of the
compressor. These are defined by the symbols printed
on the buttons themselves, as shown here.

START
Pressing this button will start the compressor if the
display shows “Ready To Start”. The compressor will
start and load if there is sufficient demand for air.

UNLOAD
Pressing this button will cause the compressor to
unload and remain unloaded. The display will indicate
the machine is “Running Unloaded”, and “Mode:
UNLOAD”.

LOAD
Pressing this button will cause the compressor to load
if the compressor is running and if the “Discharge
Pressure” is less than the “Online Pressure”. This also
returns the machine to the operating mode that is
specified by the “Mode of Operation” set point.

The other five buttons provide access to various
operator-selectable functions and machine operating
conditions. The purpose of each of these buttons is
defined by the display screen and the particular
function being performed at that time.

ARROWS
These up and down buttons have multiple functions
relating to the right half of the display screen. When
lists are presented, the buttons are used to move up or
down through the items on the list. The small arrow(s)
displayed in the upper right corner of the display
screen indicate when you can move up (designated by
arrow head pointing up) and/or down (designated by
arrow head pointing down) through the list.

When the value of a specific machine operating
parameter is highlighted on the display screen for the
purpose of changing that value, the buttons are used
to change the value itself.
STOP
Pressing this button will activate the unloaded stop
sequence. If the compressor is running loaded, it will
unload and continue to run unloaded for an adjustable
10 to 30 seconds and then stop. If the compressor is
running unloaded, it will stop immediately.

DISPLAY BUTTONS
The functions of the three buttons below the display
screen change and are defined by the words
immediately above them in the bottom line of the
screen. Each function, such as MAIN MENU, STATUS,
SET, etc., is described in appropriate sections in this

3.5.1 Lead/Lag- This setpoint is used for setting lead
or lag operation. If set to lead, the controller will load
and unload the compressor by the online and offline
setpoints. If set to lag, the controller will subtract the
lag offset (see 3.5.4) from the online and offline set
points and operate the compressor at the lower
pressure range.

3.5.6 Max Modulation Pressure- This setpoint is the
pressure the compressor will unload at if it is
modulating. As the package discharge pressure rises
toward this value, the inlet valve will start to close. The
compressor will unload once the package discharge
reaches this value. See section 5.8 for more
information on modulation.

3.5.2 Offline Pressure- This setpoint is the pressure
the compressor will unload at if it is operating in on/off
line mode.

3.5.7 Stop Delay Time- This setpoint is the minimum
amount of time the compressor will run unloaded
before stopping. This period does not apply to alarms
(shutdowns).

3.5.3 Online Pressure- This setpoint is the pressure
the compressor will load at.
3.5.4 Lag Offset- This setpoint is used with the
lead/lag operation. If the lead/lag set point is set to lag
(see 3.5.1), the value of the lag offset will be
subtracted from the online and offline setpoints.

3.5.8 Star-Delta Time- This setpoint is only used with
star-delta starters. It is not used if the starter is full
voltage or a remote starter. This is the time period
between starting and star-delta transition.
3.5.9 Contrast- This setpoint is used to improve the
display on the Intellisys.

3.5.5 Mode of Operation- This setpoint is used to
select the operating mode of the compressor. The

Items Required
In addition to the tools normally found in any reasonably
equipped serviceman’s toolbox, the following items
should be available at the work site:
1) Suitable drain pan and container to hold lubricant
drained from unit.
2) A quantity of proper lubricant sufficient to refill the
compressor.
3) A minimum of one replacement coolant filter element
of the proper type for the unit to be worked on.
There is a coolant drain hose supplied with each
compressor. The drain hose is placed in the starter box
when shipped from the factory.
The coolant should be drained soon after the compressor
has been shut down. When the coolant is hot, drainage
will be more complete and any particles in suspension in
the coolant will be carried out with the coolant.
Hot coolant can cause severe injury. Use care when
draining separator tank.
To drain the unit, remove plug from drain valve located on
the bottom of the separator tank. Install supplied drain
hose and fitting assembly in end of drain valve and place
end of hose in a suitable pan. Open drain valve to start
drainage. After draining is complete, close valve, remove

controlled. The smaller motors must be greased with a
lesser amount of grease than larger motors.

Motors must be greased periodically.
See Operator’s Manual for procedure.

4.10 MOTOR LUBRICATION (Continued)
Grease relief along shaft can occur, precluding necessity
of removing this plug if inaccessible. The inlet grease gun
fittings and outlet plugs (or spring-loaded reliefs) are
located at each end of the motor housing. The drive end
reliefs protrude out the circumference of the lower portion
of the end bell near a flange bolt. The drive end outlet
plugs are located just behind the flange in the air intake
area at about the 5 or 6 o’clock position.

WARNING

1) Free drain hole of any hard grease (use piece of wire
if necessary).
2) Use a hand lever type grease gun. Determine in
advance the quantity of grease delivered with each
stroke of the lever. A graduated cylinder showing
cubic centimeters (cc) may be used, or a 35mm film
canister can give a close approximation for 2 cubic
inches when filled.

3) Add the recommended volume of the recommended
lubricant. Do not expect grease to appear at the
outlet, but if it does, discontinue greasing at
once.
4) Run motor for about 30 minutes before replacing outlet plugs or reliefs. BE SURE TO SHUT MOTOR
DOWN, DISCONNECT POWER, LOCK OUT AND
TAG, AND REPLACE THESE DRAIN FITTINGS TO
PRECLUDE LOSS OF NEW GREASE AND
ENTRANCE OF CONTAMINANTS!

incompatibility of greases. If there is not a grease
nameplate on the motor use:

MOTOR BEARING MAINTENANCE
(STORED UNITS)
To ensure that complete contact is maintained between
the motor bearings and the bearing grease on units to be
placed in storage for extended intervals, the following
motor maintenance procedure should be adhered to:
1) Prior to placing a unit in storage, rotate the motor
several revolutions by hand in the proper direction of
rotation.
2) Thereafter, rotate the motor as described in Step 1 at
three month intervals until such time as the unit is
placed in service.
3) If the storage time is to exceed a total of nine (9)
months duration, the compressor must be ordered
with long term storage option.

4.11 LONG TERM STORAGE
GENERAL
The factory, upon special request, prepares compressor
units for long term storage. In such cases, a special
bulletin is supplied for storage and start-up procedures.

Follow these precautions to minimize damage from
static electricity. Static can cause severe damage to
microcircuits.
1)

Make the least possible movement to avoid building up static electricity from your clothing or tools.

The bulletin provides special procedures for rotation and
lubrication of compressors during storage.

Discharge potential static electricity by touching
(grounding) yourself to the starter box.

Before actual start-up of the compressor, the unit must
be drained of coolant containing vapor space inhibitors.
Procedure for long term storage start-up is covered in the
special bulletin APDD 339.

Handle circuit boards only by their edges.

Do not place the controller or power supply
assembly on any metal surface.

4.12 COOLANT/LUBRICANT CHANGEOUT
Ingersoll-Rand does not recommend changeout of
coolant/lubricants, however, if a coolant/lubricant
change cannot be avoided, procedure APDD 106E-87
should be obtained from your Ingersoll-Rand
representative.

Leave the replacement parts in their protective
bags until ready for installation.

Tools:
Screwdriver Size #1, flathead
3/8 inch hex driver
Before removing any components, open the starter box
door and check all wiring for tightness. A loose wire or
bad connection may be the cause of problems.

4.13 INTELLISYS REMOVAL
Ensure the compressor is isolated from the
compressed air system by closing the isolation
valve and venting pressure from the drip leg.
Ensure the main power disconnect switch is locked
open and tagged (See Figure 4.13-1).

This section gives guidelines for removing/replacing the
Intellisys Controller assembly and the Intellisys Power
Supply assembly. The controller is mounted in the
starter box door, and the power supply is mounted on
the upper right corner of the starter backpanel on the
inside-rear of the starter box.
Controller Removal:
1)

Open the starter box door.

Remove each plug-in connector, labeled P1-P10,
from the sides of the controller. If any of the
cables are not labeled, label them with the
appropriate plug designator, P1-P10. These
must be plugged into the correct sockets in
the replacement controller.

Remove and save the Option Module if one is
plugged into P9. This must be installed in the
replacement controller. Note that it is keyed to
plug into P9 only one way.

Remove the six holding screws from the controller on the inside of the starter box door.

Remove the four screws holding the power
supply to the starter plate, save them for
mounting the replacement board, and remove
the power supply.

4.14 COOLANT HOSES
The flexible hoses that carry coolant to and from the oil
cooler may become brittle with age and will require
replacement. Have your local Ingersoll-Rand distributor
check them every 2 years.

Ingersoll-Rand recommends incorporating predictive
maintenance, specifically the use of coolant and vibration
analysis, into all Preventative Maintenance programs.
Predictive Maintenance is designed to increase system
reliability and prevent costly downtime. Through the use
of sophisticated diagnostic tools, including fluid, vibration,
and optional air analysis, IRA Certified Service
Technicians can identify and correct potential problems
BEFORE they can cause expensive unscheduled
downtime.
How does predictive analysis work? By establishing an
initial baseline for normal operation, and then regularly
monitoring fluid and vibration conditions, any sudden
deviation or significant increase from this baseline can be
identified and investigated to pinpoint the cause. More
quickly diagnosing potential problems can directly save
money by preventing costly failures and reducing or
eliminating downtime. In addition, regular condition
monitoring also helps to maximize the time between
expensive preventative maintenance intervals, such as
component rebuilds and coolant changes.

Ensure the compressor is isolated from the
compressed air system by closing the isolation valve
and venting pressure from the drip leg.

4.16 COOLANT SAMPLING PROCEDURE

Ensure the main power disconnect switch is locked
open and tagged.

Bring unit up to operating temperature. Draw sample,
using pump kit, from separator tank port. DO NOT draw
sample from drain port or oil filter. Use new hose on
pump for each sample, failure to do this can give false
readings.

REMOVAL
Remove enclosure panels.
Drain coolant into a clean container. Cover the container
to prevent contamination. If the coolant is contaminated,
a new charge of coolant must be used.
Hold fitting securely while removing hose.

5.0 SYSTEMS
5.1 GENERAL SYSTEM INFORMATION
The SSR compressor is an electric motor driven, single
stage, screw compressor—complete with accessories
piped, wired and baseplate mounted. It is a totally
self-contained air compressor package.
A standard compressor is composed of the following:
■ Inlet air filtration
■ Compressor and motor assembly
■ Pressurized coolant system with cooler
■ Separation system
■ Capacity control system with stepper motor inlet
■ Motor starting control system
■ Instrumentation
■ Safety provisions
■ Aftercooler
■ Moisture separator and drain trap.
Optional accessories can provide for such things as
automatic starting and stopping, remote starting or
stopping, and sequencer.
The motor, airend, separator tank, and piping are
mounted on independent supports. The supports are
isolated from the base by rubber isolation mounts.
Flexible hoses are utilized on the separator tank coolant
out and air discharge to isolate the motor/airend/tank.
5.2 AIR COOLED COMPRESSORS
DESIGN TEMPERATURES
The standard compressor is designed for operation in an
ambient range of 35°F to 115°F (1.7°C to 46°C). When
conditions other than the design levels described are
encountered, we recommend you contact your nearest
Ingersoll-Rand representative for additional information.
The standard maximum temperature 115°F (46°C) is
applicable up to an elevation of 3300 ft (1000 m) above
sea level. Above this altitude, significant reductions in
ambient temperature are required if a standard drive
motor is to be used.
COOLANT COOLER
The cooler is an integral assembly of core, fan and
fan-motor, all mounted in the end section of the
compressor enclosure. The cooling air flows in through
the left end of the enclosure, through the vertically
mounted cooler core, and discharges upward through the
right end of the enclosure.

COOLING FAN MOTOR
In a standard compressor, the cooling fan motor is wired
at the factory. It is a three-phase motor, protected by a
suitable circuit breaker and overload relay. The fan motor
is energized at the same time the compressor drive
motor is energized. The fan motor overload is wired in
series with the compressor drive motor overload. If an
overload occurs in the fan motor circuit, both the fan
motor and compressor drive motor will stop.
AFTERCOOLER
The discharge air aftercooling system consists of a heat
exchanger (located at the cooling air entrance of the
machine), a condensate separator, and an automatic
drain trap.
By cooling the discharge air, much of the water vapor
naturally contained in the air is condensed and
eliminated from the downstream plant-piping and
equipment.
5.3 COOLANT SYSTEM
Coolant is forced by pressure from the receiver/separator
sump to the inlet port of the coolant cooler and the
bypass port of the thermostatic control valve.
The thermostatic control valve controls the quantity of
coolant necessary to provide a suitable compressor
injection temperature. When the compressor starts cold,
part of the coolant will bypass the cooler. As the system
temperature rises above the valve setting, the coolant will
be directed to the cooler. During periods of operation in
higher ambient temperatures, all the coolant flow will be
directed through the cooler.
The compressor injection minimum temperature is
controlled to preclude the possibility of water vapor
condensing in the receiver. By injecting coolant at a
sufficiently high temperature, temperature of the
discharge air and lubricant mixture will be kept above the
dew point.
The controlled temperature coolant passes through a
filter to the airend under constant pressure.

5.4 COMPRESSED AIR SYSTEM
The air system is composed of:
1)
2)
3)
4)
5)
6)
7)

Inlet air filter
Inlet valve/stepper motor
Rotors
Coolant/air separator
Minimum pressure/check valve
Aftercooler
Moisture separator/drain trap

Air enters the compressor, passing through the inlet air
filter and butterfly inlet valve.
Compression in the screw-type air compressor is created
by the meshing of two helical rotors (male and female) on
parallel shafts, enclosed in a heavy-duty cast iron
housing, with air inlet and outlet ports located on
opposite ends. The grooves of the female rotor mesh
with, and are driven by, the male rotor. Tapered roller
bearings at the discharge end prevent axial movement of
the rotors.
The air-coolant mixture discharges from the compressor
thru a discharge check valve into the separation system.
This system, self-contained in the separator tank,
removes all but a few PPM of the coolant from the
discharge air. The coolant is returned to the system and
the air passes to the aftercooler. The aftercooling system
consists of a heat exchanger, a condensate separator,
and a drain trap. By cooling the discharge air, much of
the water vapor naturally contained in the air is
condensed and eliminated from the downstream
plant-piping and equipment.
During unloaded operation, the butterfly inlet valve
closes, via stepper motor, and the blowdown solenoid
valve opens, expelling any compressed air back to the
compressor inlet.
5.5 COOLANT/AIR SEPARATION SYSTEM
The coolant/air separation system is composed of a
separator with specially designed internals, a two-stage
coalescing-type separator-element, and provision for
return of the separated fluid back to the compressor.

Internal baffles maintain the circumferential flow of
remaining coolant droplets and air. In an almost
continuous change of direction of flow, more and more
droplets are removed from the air by inertial action and
then returned to the sump.
The air stream, now essentially a very fine mist, is
directed to the separator element.
The separator element is constructed with two
concentric, cylindrical sections of closely packed fibers,
each held in steel mesh. It is flange-mounted at the
separator-outlet-cover.
The air stream enters the separator element radially
and the mist coalesces to form droplets. The droplets
collected on the outer first stage fall to the separator
sump. Those collected on the inner second stage
collect near the outlet of the element, and are drawn
back to the compressor inlet through a filter-screen and
orifice fitting installed in the separator scavenge line.
The air stream, now essentially free of coolant, flows
from the separator to the aftercooler, then to the
condensate separator, and on to the plant air system.
5.6 ELECTRICAL SYSTEM
The electrical system of each SSR compressor is built
around the microprocessor-based Intellisys controller.
The standard electrical/electronic components,
enclosed in a readily accessible enclosure include:
1) IntelIisys controller
2) Compressor motor starter, with auxiliary contacts
and overload relays
3) Cooling fan motor overload relays and circuit
breaker or fuses
4) Intellisys Power Supply Board
5) Control transformer and fuses
Options, such as power outage restart can be enabled
by installing plug-in (option) modules in the Intellisys
controller.

OPERATION
The coolant and air discharging from the compressor
flow into the separator through a tangential discharge
outlet. This outlet directs the mixture along the inner
circumference of the separator, allowing the coolant
stream to collect and drop to the separator sump.

5.6 ELECTRICAL SYSTEM (Continued)
STAR-DELTA TYPE STARTER
By use of the Star-Delta type starter, the compressor
motor can be started and accelerated using a greatly
reduced “inrush” electric current. The starter is completely
automatic and controlled by the Intellisys controller. Refer
to the Electrical Schematic 8.1 in Section 8.0.
5.7 STEPPER MOTOR INLET CONTROL
The inlet valve is opened and closed by a stepper motor
mounted on the inlet valve. The Intellisys controller
regulates the stepper motor to precisely position the inlet
valve based upon the demand of the plant air system
(See Section 5.8).
The stepper motor is maintenance free. Bearings are
lubricated at the factory and sealed for life.
No adjustment of the stepper motor/inlet valve system is
required.
5.8 CAPACITY CONTROL
The SSR compressor is supplied, as standard
equipment, with three operator selectable capacity
control systems, each designed for different plant air
requirements:
— MOD/ACS (Modulation/Automatic
Control Selector)
— On-Off Line
— Modulation Only
The desired control is selected at the Intellisys control
panel (See Section 3.0).
AUTOMATIC UNLOADED START
The compressor will always start in the unload mode.
When unloaded, the inlet valve is nearly closed, the
blowdown solenoid valve is open (tank vented), and the
compressor is operating at minimum power. The Intellisys
will open the inlet valve slightly to maintain the proper
sump pressure to ensure positive coolant flow and
smooth, quiet operation. When the injected coolant
temperature is less than 120°F (49°C), a separator
(sump) pressure of 45-50 psig (3.1 - 3.4 bar) will be
maintained. When the injected coolant temperature is
above 120°F (49°C), a receiver pressure of 24-33 psig
(1.7 - 2.3 bar) will be maintained. The minimum pressure
check valve will prevent any backflow of air from the plant
air system during unloaded operation.

ON-OFF LINE CONTROL
For those plants which have a widely varying air demand,
on-off line control will deliver air at full capacity
(compressor maximum efficiency condition) or will
operate at zero capacity (compressor minimum power
condition). The compressor is controlled by the Intellisys,
responding to changes in plant air pressure. The
Intellisys/stepper motor opens the inlet valve and closes
the blowdown valve (3SV) whenever plant air pressure
drops below the on-line pressure set point. The
compressor will then operate to deliver full capacity air to
the plant system. If the plant air system pressure rises to
the off-line set point of the Intellisys, the inlet valve closes
and the blowdown solenoid valve opens the separator
vent line, allowing separator pressure to drop. The
compressor will continue to run with minimum power
draw.
MODULATION/ACS CONTROL
For those plants which have relatively high, constant
air-demand relative to the compressor capacity, the
recommended control mode is modulation.
The modulation control system retains the features of
on-off line control, but provides for throttling of the inlet
flow up to the modulation off line air pressure set point.
The throttling position of the inlet valve is controlled by
the Intellisys, allowing the stepper motor to “trim” the inlet
valve position as dictated by the line pressure.
The modulating pressure range is 10 psig (.7 bar).
Modulation begins when the line pressure reaches the
maximum modulation pressure setting minus 10 psig (.7
bar) and continues as/if the line pressure rises.
Modulation becomes stable when the compressor output
equals the plant air demand. When the modulation is at
the maximum modulation pressure setting the maximum
capacity reduction will be down to approximately 60
percent of the compressor rated capacity. If the air
demand has decreased to a level below the 60 percent
modulated output, the line pressure will increase slightly
to actuate the Intellisys, unloading the compressor and
venting the separator.

5.8 CAPACITY CONTROL (Continued)
MODULATION/ACS CONTROL (Continued)
The automatic control selector (ACS) is designed to
continuously monitor the plant air demand and select
either the on-off line, or the modulate control mode whichever is most desirable at any time during an
operating day.
It allows the compressor to operate in its most efficient
mode without attendance, thereby reducing power costs
to a minimum.
When the compressor operates in the on-off line control
mode, the length of time the compressor remains in the
“off line” condition is an indication of the plant air
demand. Intellisys controller is sensing and awaiting a
sufficient line pressure decrease before signaling a shift
to the on line mode. If the “off line” time period is
relatively short, thereby indicating a high demand for air,
it is preferable to shift the control system to upper range
modulation.
The Intellisys does this, and does it automatically if the
compressor unloads 3 times within a 3 minute time
period.
If later, the plant demand decreases, and even under
modulate control the line pressure reaches the setting of
the Intellisys controller and the control shifts to the “off
line” mode, the time in this mode will still be monitored. A
long “off line” time period indicates a low plant air
demand, indicating the desirability of operating in the
on-off line mode.
The Intellisys then does this, and does it automatically if
the compressor operates unloaded for more than 3
minutes.
MODULATION ONLY
If MODULATION ONLY is turned on in the set point
routine, the unit will shift to Modulation control mode
immediately when the unit is running. The 3 cycles within
3 minutes time period required for ACS to change to
Modulation mode is bypassed. The unit will stay in
Modulation mode until the UNLOAD button is pressed or
the Mode of Operation set point is changed.

5.9 AUTOMATIC START/STOP CONTROL
Many plant air systems have widely varying air demands
or large air storage capacity which allows for automatic
standby air capacity control.
During periods of low air demand, if the line pressure
rises to the upper set point, the Intellisys begins to time
out. If the line pressure remains above the lower set point
for as long as the set time, the compressor will stop. At
the same time the display will indicate the compressor
has shut down automatically and will restart
automatically. An automatic restart will occur when the
line pressure drops to the lower set point.
The upper and lower set points and shutdown delay time
are set on the Intellisys control panel. There is a 10
second delay after shutdown during which the
compressor will not restart even if line air pressure drops
below the lower set point. This is to allow the motor to
come to a complete stop and the Intellisys controller to
collect current data of operating condition. If line air
pressure is below the lower set point at the end of 10
seconds, the unit will start unless the load delay timer is
set greater than 10 seconds.
Auto Restart Delay
This is the number of seconds the line pressure must
remain below the online set point before the compressor
will start if it was stopped due to an auto start/stop
situation. This timer will not delay an auto restart if the
time is set to 0.
Automatic Start/Stop Operation
When in operation, the compressor must meet two
specific timing intervals before the Intellisys controller will
stop the unit in an Automatic Start/Stop situation.
For this discussion, the timers will be called timer “A” and
timer “B”.
FIRST
Timer “A” prevents the compressor from automatically
starting more than 6 times an hour by requiring the unit
to run at least 10 minutes after each automatic start.
This 10 minute run period can be loaded, unloaded or a
combination of the two and allows dissipation of heat
generated within the motor windings at start.

SECOND
After the compressor has started and reached the off-line
setting and has unloaded, timer “B” requires the unit to
run unloaded for a period of time that the operator can
adjust between 2 and 60 minutes.
The setting of timer “B” is part of the options setpoint
routine and the timer cancels any accumulated time if the
compressor reloads before the timer cycle has finished.
An important point... This unloaded run time may, or may
not, be included in the mandatory 10 minute run time
used to cool the motor windings.
When the compressor has completed the settings of both
timer “A” and timer “B”, the Intellisys controller stops the
compressor and displays “STOPPED IN AUTO
RESTART.”
Pressure sensor 4APT continues to monitor the package
discharge pressure and sends information to the
controller which automatically restarts the compressor
when the pressure falls to the on-line setting.
An advantage to this method of automatic start/stop
control is allowing the compressor to stop much sooner
in certain situations and timer settings, thereby reducing
power costs.

Some Examples of Operation
EXAMPLE 1
The operator selects an unloaded run time of 2 minutes
in the OPTION routine and starts the compressor. The
unit runs loaded for 8 minutes, unloads and then runs
unloaded for two more minutes.
The total running time is 10 minutes which satisfies timer
“A” plus the unit ran two minutes unloaded which also
satisfies timer “B,” therefore, the unit stops automatically.
This example shows how timer “B” can sometimes be
included within the timer “A” interval. Think of the two
timers as running parallel.
EXAMPLE 2
The operator selects an unloaded run time of 3 minutes
in the OPTION routine and starts the compressor. The
unit runs loaded for 10 minutes and then unloads.
At this point, timer “A” has been satisfied but timer “B” still
wants the compressor to run unloaded 3 more minutes
before allowing an automatic stop.
The total run time for this example will be 13 minutes.
Remember.... If the unit reloads before timer “B” finishes
the 3 minute setting, the partial time is canceled and
timer “B” must restart the 3 minute cycle when the
compressor unloads again.

EXAMPLE 3
The operator selects an unloaded run time of 10 minutes
in the OPTION routine and starts the compressor. The
unit runs loaded 12 minutes and then unloads.
After 12 minutes of running, the 10 minute mandatory
run-time for timer “A” has been met but the compressor
must continue to run unloaded an additional 10 minutes
to satisfy timer “B”.
After 10 minutes of unloaded run time, the compressor is
stopped automatically and the total run time was 22
minutes.
5.10 REMOTE START/STOP
The remote start/stop option allows the operator to
control the compressor from a remote mounted start/stop
station.
Two different switches can be wired to the controller for
remote start/stop. (Refer to Electrical Schematic 8.1 for
wiring locations). The switches are customer supplied
and must be of momentary type. The stop switch
contacts are normally closed and the start switch
contacts are normally open.

When starting the compressor from the remote location,
the Start button must be held depressed for
approximately 2 seconds to activate the remote start
function and then released within a maximum of 7
seconds or a Remote Start Failure alarm will occur.

7.0 OTIONS
7.1 POWER OUTAGE RESTART OPTION
For customers that have interruptions in their incoming
power supply to the compressor and must maintain an
uninterrupted supply of compressed air, the Power
Outage Restart Option allows an Intellisys compressor to
restart automatically 10-120 seconds (adjustable) after
incoming power is restored.
The Power Outage Restart Option is turned on by
plugging in the required option module and enabling it
thru the OPTION’S set point routine. The restart time
delay, which is adjustable from 10-600 seconds, can also
be adjusted while in the option’s set routine on the
Intellisys controller. Any time power is restored to the
compressor after a power interruption, a horn located on
the side of the starter box will sound during the restart
time delay (10-600 seconds), after which the compressor
will automatically start. After starting, the compressor will
return to the mode of operation that the compressor was
in prior to the power interruption.
This option may be factory installed or a field installation
kit is available.
7.2 SEQUENCER
The sequencer option is turned on by enabling it through
the OPTIONS set point routine. Enabling this
option will allow the compressor to be controlled by an
external device, such as an ISC or sequencer, using
the communications port (P7) on the Intellisys.
7.3 LOW AMBIENT
The low ambient option is turned on by enabling it through
the OPTIONS set point routine. Also temperature sensor,
3CTT, is added to the compressor and connected at P6-7
& 8 on the Intellisys. The options set point, minimum
cooler out temperature, is set to the minimum temperature
at which the unit can load. When this option is enabled,
the compressor, after being started, will not load until the
Intellisys reads a temperature from 3CTT at or higher
than the value of the minimum cooler out temperature set
point. If this option is enabled without installing 3CTT,
a SENSOR FAILURE 3CTT alarm will occur.
7.4 SEPARATOR DELTA-P SOLENOID
The separator delta-p solenoid option is turned on by
enabling it through the OPTIONS set point routine.
When this option is enabled, the Intellisys will measure
the pressure drop across the separator element by

first reading the wet side sump pressure. Next the
Intellisys will momentarily energize solenoid that will
switch the dry side sump pressure to the sump pressure
sensor (3APT). The Intellisys will then read the dry
side sump pressure and subtract it from the wet side
sump pressure to measure the pressure drop across the
separator element. Do not enable this option if the
separator delta-p solenoid is not installed. This will
result in an incorrect measurement of the pressure
drop across the separator element.
7.5 SEPARATOR DELTA-P SENSOR
The separator delta-p sensor option is turned on by
enabling it through the OPTIONS set point routine.
When this option is enabled, the Intellisys will measure
the pressure drop across the separator element by
subtracting the dry side sump pressure (6APT) from the
wet side sump pressure (3APT). Do not enable this
option if the separator delta-p sensor is not installed.
This will result in an incorrect measurement of the
pressure drop across the separator element and a
6APT sensor failure warning.
7.6 HIGH DUST FILTER
The high dust filter option is turned on by enabling it
through the OPTIONS set point routine. If this option
is enabled, the Intellisys; will change its measurement of
the inlet filter. Do not enable this option unless a high
dust filter is installed.
7.7 LEAD/LAG CYCLE LENGTH
The lead/lag cycle length option allows the Intellisys to
automatically switch the online and offline pressure
settings to the lead or lag values after a programmed
number of hours. This option is enabled by selecting a
number of hours greater than 0 in the OPTIONS set point
routine.
7.8 SCHEDULEDSTART/STOP
The scheduled start/stop option allows the customer to
automatically start and stop the compressor once each
day, based on the real time clock. This is an installed
option and is enabled by selecting a scheduled start and
scheduled stop time. Setting the scheduled start and
scheduled stop times to the same value will disable this
option.

7.9 REMOTE LOAD/UNLOAD
The remote load/unload option gives the operator the
ability to control the loading and unloading of the
compressor. This option is enabled when two switches
are wired to the Intellisys to perform this function.
The firstswitch is the master/local input (P3, 25 & 26)
and the second switch is the load/unload input (P3,
27 & 28). If the master/local switch is closed, the
Intellisys will read the load/unload switch for loading
and unloading the compressor. If the load/unload switch
is closed, the Intellisys will load the compressor.
If the load/unload switch is open, the Intellisys will
unload the compressor. If the master/local switch is
open, the Intellisys will ignore the load/unload switch
and operate the compressor normally.
7.10 MODBUS
The Modbus option uses the Modbus protocol and
modbus address set points in the OPTIONS menu. This
is used by the Ingersoll-Rand service organization.
7.11 INTEGRAL SEQUENCING
Integral sequencing allows one compressor, the lead, to
sequence up to 3 other compressors. The compressors
are daisy chained together using port P8 on the Intellisys.
Each compressor has a unique address and the lead
compressor will sequence the other units in numerical
order based on that address.
The lead compressor will be the first to load and the last
to unload. It is also the only compressor that can
modulate. If the lead compressor’s mode of operation is
Mod/ACS or Modulation Only, it will modulate when it is
loaded. Once loaded, if pressure falls to its online set
point, the lead compressor will transmit a load command
to the next compressor in sequence. The lead compressor
will then wait for a period of time for the line pressure to
rise. This time period is determined by the load delay time
set point. At the end of this time period, if line pressure is
not rising, the lead compressor will transmit a load
command to the next compressor in sequence. This will
be repeated until the line pressure starts to rise.

When line pressure rises to the lead compressor’s offline
set point, it will transmit an unload command to the last
loaded compressor in the sequence. The lead compressor
will do this every 10 seconds until the line pressure starts
to fall.
After a certain amount of time or at a certain time, the
lead compressor can change the sequence by transferring
the lead to the next compressor in the sequence. If the set
point, Lead Change - Hours, is set to a value greater than
0, the unit will operate as the lead compressor for that
number of hours before transferring the lead. If Lead
Change - Hours is set to 0, the set points Lead Change Day and Lead Change - Time will be used to determine
when the lead will be transferred. The Lead Change - Day
set point will contain the day of the week the lead will be
transferred. The time of the day will be contained in the
Lead Change - Time set point. The lead will be transferred
when the real time clock matches these 2 set points.
To connect the compressors for integral sequencing put
the 4 position connector into port P8. One connector, I-R
part number 39186101, will be needed for each
compressor. The total length of cable for an integral
sequencing system is not to exceed 1000 feet. For the
cable, use I-R part number 39204508 or equivalent. This
is a 4 wire, twisted pair cable. Use one pair for pins 1 and
2 and the other pair for pins 3 and 4. The connection on
port P8 is a one to one connection. The wire on pin 1 on
the first compressor will connect to pin 1 on the second
compressor and so on. This is true for all 4 wires.

9.0 WATER QUALITY
RECOMMENDATIONS
Water quality is often overlooked when the cooling
system of a water cooled air compressor is examined.
Water quality determines how effective the heat transfer
rate, as well as the flow rate will remain during the
operation life of the unit. It should be noted that the
quality of water used in any cooling system does not
remain constant during the operation of the system. The
water makeup is affected by evaporation, corrosion,
chemical and temperature changes, aeration, scale, and
biological formations. Most problems in a cooling system
show up first in a reduction in the heat transfer rate, then
in a reduced flow rate, and finally with damage to the
system.
There are many constituents in the water system that
must be balanced to have a good stable system. The
following is a list of the major components that should be
monitored:
SCALE
Scale formation inhibits effective heat transfer, yet it does
help prevent corrosion. Therefore, a thin uniform coating
of calcium carbonate is desired on the inner surfaces.

PARAMETER

Perhaps the largest contributor to scale formation is the
precipitation of calcium carbonate out of the water. This is
dependent on temperature and pH. The higher the pH
value the greater the chance of scale formation. Scale
can be controlled with water treatment.
CORROSION
In contrast to scale formation is the problem of corrosion.
Chlorides cause problems because of their size and
conductivity. Low pH levels promote corrosion, as well as
high levels of dissolved oxygen.
FOULING
Biological and organic substances (slime) can also cause
problems, but in elevated temperature environments such
as cooling processes, they are not major concerns. If
they create problems with clogging, commercial shock
treatments are available.
To ensure good operation life and performance of the
compressor cooling system, the recommended
acceptable ranges for different water constituents are
included below:

Corrosivity (hardness,
pH, total dissolved solids,
temperature at inlet,
alkalinity)

Dissolved oxygen

Recommended equipment for on-site analysis includes a
thermometer, pH meter, and dissolved oxygen meter.
Dissolved oxygen and temperature must be measured
on-site and it is recommended that pH be measured
on-site. All other analyses should be performed by a
professional water quality analyst. The Langelier Index
(Ll) is calculated using the following equation and the
tables found on the following pages.
Ll = pH - (9.30 + Total Dissolved Solids chart value +
Temperature chart value ) + Hardness chart valve +
Alkalinity chart value)
The Ll is zero when the water is in chemical balance. If
the Ll is greater than zero, there is a tendency to form
scale. If the Ll is less than zero, the water tends to be
corrosive.
Dissolved oxygen may be controlled in closed cooling
towers. Several types of treatments are commercially
available to remove dissolved oxygen. For open cooling
towers, dissolved oxygen is not an easily controlled
parameter. Also, a filtration system is recommended for
the water going into the air compressor when using an
open cooling tower.
It should be noted that Ingersoll-Rand’s guidelines and
recommendations should be used in evaluating the water
systems and the problems that may occur in the normal
operation of our air compressors. If water problems
persist or are not covered above, you should consult a
professional.
