role in its performance and safety. The following is a brief description of some of the more
type of power system the site has before sizing the drive.
Delta / Wye with grounded Wye neutral:
voltage with a 30 degree phase shift. Depending on the output connections from the drive to
motor, the grounded neutral may be a path for common mode current caused by the drive
output.
Delta / Delta with grounded leg:
input and output. Again, depending on the output connections from the drive to motor, the
grounded neutral may be a path for common mode current caused by the drive output.
Ungrounded secondary:
Grounding of the transformer secondary is essential to the safety of personnel as well as
voltages between the chassis of the drive and the internal power structure components.
In many cases this voltage could exceed the rating of the input MOV protection devices of
the drive causing a catastrophic failure. In all cases, the input power to the drive should be
referenced to ground. If the transformer can not be grounded, then an isolation transformer
must be installed with the secondary of the transformer grounded.
10
POWER DISTRIBUTION SYSTEMS
Resistance grounding and ground fault protection:
Connecting the Wye secondary neutral to ground through a resistor is an acceptable
method of grounding. Under a short circuit secondary condition, any of the output phases
to ground will not exceed the normal line to line voltage. This is within the rating of the MOV
input protection devices on the drive. The resistor is often used to detect ground current
through this resistor, care should be taken to properly connect the drive motor leads using
the recommended cables and methods. In some cases, multiple drives on one transformer
can produce a cumulative ground current that can trigger the ground fault interrupt circuit.
Open Delta (consult factory):
encountered where only single phase power is available and three-phase power is required.
The technique uses two single phase transformers to derive a third phase. When used to
one transformer. This system provides poor regulation and it is possible that only the two line
connected phases will provide power. In this case the drive must be derated to 50% of its
rating. (Ex. A 20 HP 230 volt drive now becomes a 10 HP 230 volt drive.)
Single Phase Connection:
single phase input. Only part of the three phase input bridge is used. Ripple current becomes
bank and DC choke). The result is that the drive must be derated to 50% current. Single phase
will not work with an SCR front end drive.

INTRODUCTION
Input Power and Line Transformer Requirements
The Aquavar CPC™ requires that the input line voltage and transformer power that meet
certain phase and balance requirements. If you or your installing electrical contractor is in
doubt of the requirements, the following provide guidelines for the Aquavar CPC. When
in doubt contact the local power utility or the factory.
Drive input isolation transformers are not generally required for the Aquavar CPC. The
needed, an input line reactor is not required.
NOTE: 60 THROUGH 550 HP UNITS PROVIDE AN ACTUAL 3% IMPEDANCE LINE REACTOR
BUILT INTO THE DRIVE CABINET.
transient protection (MOV’s and EMI capacitors) therefore earth ground potential reference is
many different power grounding schemes. The drive requires only that the steady state RMS
voltage from any input line to ground be always less than 110% of the nominal power line to
line to ground be less than 110% of the nominal power line to neutral voltage.
Drive input isolation or dry type transformers may be required for the following:
1. Step up or down: An input transformer may be required to step the local input power
line voltage up or down to the level of the drive input rating.
2. Ground Isolation: An input isolation transformer with a direct or a high impedance wye
neutral secondary ground connection may be required to establish a local power source
with a ground relationship different from the utility power source.
A. If ground isolation is required to prevent a ground fault in one section from shutting
down equipment in another section.
B. To bring local line voltages within the line to ground limits (110% balance) stated in
the opening paragraph.
C. Some ground fault protection schemes and peripheral components require a
grounded neutral power source.
D. A symmetrical wye neutral grounded power source along with proper ground wiring
techniques according to NEC (good ac grounding from motor to drive and from
drive to earth ground) provides the best means to control the ground currents that
the drive switching frequency and dv/dt rate insert into the motor frame and shaft.
3. Phase shifting delta-wye or “zig-zag” isolation transformers are used to feed 12 or 18
pulse drive inputs to provide harmonic mitigation.
If an isolation transformer is used for 6 pulse input, the best choice is ONE three phase,
six winding transformer. A delta primary is best for third harmonic cancellation. A
wye secondary avoids circulating current problems and provides the very desirable option
of grounding the secondary neutral for minimum voltage stress and ripple to ground. The
transformer should have a KVA rating at least 1.1 times the maximum connected HP. A K
12
if transformer impedance is greater than 3%. The transformer manufacturer may provide
derating for non K Factor rated transformers to operate at the drive produced K Factor levels.
Three single phase transformers can be
used if they are identical for phase to phase symmetry and balance. A wye connected
primary neutral should never be grounded. Great care should be taken with delta primary
circulating currents and unacceptable transformer heating.
WARNING! Never use phase converters with drives as nuisance tripping and possible
damage may occur. Size the drive for single phase input using 50% derate factor.
WARNING! Use of “Open Delta” 230 volt power systems should be sized using the
50% derate factor. Consult factory.
Sometimes drive input isolation transformers are specied to deal with one or more of
the following issues:
1. Short Circuit Protection: Input transformers are sometimes used to provide impedance
to reduce the available short circuit current to levels that the input clearing devices,
such as fuses or circuit breakers, are rated to handle. Line reactors can perform this
impedance function much more cost effectively.
2. Transient Protection: Input transformers are sometimes used to provide transient
surge impedance. All the Aquavar CPC drives have capacitors and MOV’s (Metal Oxide
Varistor transient protectors) providing 120 to 360 joules, line to line and line to ground
transient protection. Isolation transformers are not required for this protection within
those energy levels. Additional distribution transformer primary transient surge arrestors
levels. MOV’s are rated to handle high levels of one shot transient energy. MOV’s are not
meant to handle continuously recurring transients. A problem of continuously recurring
transients should be corrected before connecting a drive.
3. Harmonic Mitigation: Input transformers are sometimes used to provide impedance to
reduce the harmonic currents generated in the drive. Line reactors can perform this
function much more cost effectively.
4. Power Factor Capacitor Isolation: Input transformers are sometimes used to provide
impedance to isolate drives from line connected power factor correction capacitors.
PWM drive inputs do not require power factor correction capacitors as drive power
power factor correction capacitors which only correct for fundamental. However drives
should be isolated from power factor correction capacitors by about 3 to 6% additional
impedance with respect to the drives. Line reactors can perform this function much more
cost effectively than isolation transformers. ABB drives have either an internal 3% line
reactor or an equivalent 3 to 5% bus reactor.
5. RFI/EMI Mitigation: Neither input isolation transformers nor line or bus reactors provide
inside the drive should be used together with all the proper wiring and grounding
neutral. Establishing a local neutral ground may require the use of an input isolation
transformer.

Tools Required
To install the AQUAVAR you need the following:
• True RMS multimeter
• Screwdrivers (as appropriate for the mounting hardware used)
• Wire stripper
• Tape measure
• Drill
• Mounting hardware: screws or nuts and bolts, four each. The type of hardware depends on
the mounting surface and the frame size:
Frame Size Mounting Hardware
R5 M6 ¼ in.
R6 M8
516 in.
Suitable Environment and Enclosure
installation, store and transport the drive according to the environmental requirements
• IP 21 / UL type 1 enclosure, indoor use only. The site must be free of airborne dust,
corrosive gases or liquids, and conductive contaminants such as condensation, carbon
dust and metallic particles.
INTRODUCTION
17
• IP 54 / UL type 12 enclosure, indoor use only. This enclosure provides protection from
airborne dust and light sprays or splashing water from all directions.
• UL Type 3R- Enclosures are intended for outdoor use to provide a degree of protection
from falling rain. Undamaged by the formation of ice on the enclosure. May be cooled by
forced air and louvers for vents.
• IP 56 / UL type 4 enclosure. Constructed for outdoor use or hose down applications.
Provides a degree of protection against falling dirt, rain, sleet, snow, windblown dust and
splashing water. Not suitable for direct sun. A sun shield or canopy may be required.
Suitable Mounting Location
• The drive must be mounted vertically on a smooth, solid surface, and in a suitable
• The minimum space requirements for the drive are the outside dimensions (see “Outside
page 137).
• The distance between the motor and the drive is limited by the maximum motor cable
length. See “Motor Connection” on page 136.
• The mounting site must support the drive’s modest weight and noise output. See
“Dimensions and Weights” on page 141.
Wiring and EMC Considerations
Determine electromagnetic compliance (EMC) requirements per local codes. In general,
always follow the NEC in the absence of a local code.
• Follow local codes for cable size, conduit, grounding and motors.
• Keep these four classes of wiring separated: input power wiring, motor wiring, control/
communications wiring. Always use separate conduit for motor/control wires.
“Cable Sizing/Rating” on page 131, “Cable Terminals” on page 135, “Input Power (Mains)
Connection” on page 136 and “Motor Connection” on page 136.
• Multiple motor wire should always be run in separate conduit. Shielded and grounded!
Control Cables
General Recommendations
Use shielded cables, temperature rated at 60º C (140º F) or above:
• Control cables must be multi-core cables with a braided copper wire screen.
Double Shielded Single Shielded
Example: JAMAK by Draka NK Cables Example: NOMAK by Draka NK Cables
connected to terminal X1-1 (for digital and analog I/O cables) or to either X1-28 or X1-32
(for RS485 cables).
INTRODUCTION
18
Route control cables to minimize radiation to the cable:
• Route as far away as possible from the input power and motor cables (at least 20 cm (8 in)).
• Where control cables must cross power cables make sure they are at an angle as near 90º
as possible.
• Stay at least 20 cm (8 in) from the sides of the drive.
Use care in mixing signal types on the same cable:
• Do not mix analog and digital input signals on the same cable.
• Run relay-controlled signals as twisted pairs (especially if voltage > 48 V). Relay-controlled
signals using less than 48 V can be run in the same cables as digital input signals.
NOTE! Never mix 24 VDC and AC power signals in the same cable.
Analog Cables
Recommendations for analog signal runs:
• Use double shielded, twisted pair cable
• Use one individually shielded pair for each signal.
• Do not use a common return for different analog signals.
Digital Cables
Recommendations for digital signal runs:
• A double shielded cable is the best alternative, but single shielded twisted multi-pair cable
is also usable.
Control Panel Cable
If the control panel is connected to the drive with a cable, use only Category 5 Patch ethernet
cable.
INTRODUCTION
19
Supply Connection
Disconnecting Device (Mains)
Install a hand-operated input disconnecting device between the AC power source (MCC) and
the drive. The disconnecting device must be of a type that can be locked to the open position
for installation and maintenance work. Follow all local NEC codes.
Fuses
See Technical Data: Fuse Sizing/Rating on pages 133 and 134.
Thermal Overload and Short-circuit Protection
The drive protects itself and the input and motor cables against thermal overload when the
cables are dimensioned according to the nominal current of the drive. No additional thermal
protection devices are needed.
WARNING! If the drive is connected to multiple motors, a separate thermal overload
switch or a circuit breaker must be used for protecting each cable and motor. These
devices may require a separate fuse to cut off the short-circuit current.
The drive protects the motor cable and the motor in a short-circuit situation when the motor
cable is dimensioned according to the nominal current of the drive.
Mains Cable (AC line cable) Short-circuit Protection
Always protect the input cable with fuses. Standard gG (US: T or L) very fast acting, fuses
will protect the input cable in short-circuit situations and prevent damage to adjoining
equipment in case of a short-circuit inside the drive.
Size the fuses according to local safety regulations, appropriate input voltage and the rated
current of the drive. For fuse ratings, see Technical Data, pages 133 and 134.
WARNING!
because they are inherently slower than fuses. Always use fuses with circuit breakers, if
you are not sure of the circuit braking capacity and mains short circuit power.
Ground Fault Protection
The drive is equipped with an internal ground fault protective function to protect the unit
protection feature. The ground fault protective function can be disabled with a parameter
contact factory for more information.
frame. These capacitors and long motor cables increase the ground leakage current and may
cause fault current circuit breakers to function.
Emergency Off Devices
For safety reasons, install the emergency off devices at each operator control station and at other
operating stations where emergency off may be needed. Pressing the stop key on the control
panel of the drive does not generate an emergency off of the motor or separate the drive from
dangerous potential.
INSTALLATION (Frames R1-R6)

Selecting the Power Cables (copper only)
General Rules
Dimension the mains (input power) and motor cables according to local regulations:
• Do not use aluminum wires.
• The cable must be able to carry the drive load current. See Technical Data for the rated
currents.
• The cable must be rated for at least 70º C (158º F) maximum permissible temperature of
conductor in continuous use. For US, follow local codes for cable size, or refer to NEC table
310.16.
• The inductance and impedance of the PE conductor/cable (grounding wire) must be rated
according to permissible touch voltage appearing under fault conditions (so that the fault
point voltage will not rise excessively when an ground fault occurs).
• 600 VAC cable is accepted for up to 500 VAC concerning the entire AQUAVAR CPC range.
four-conductor system used up to 30 kW motors cannot be used.
Compared to a four conductor system, the use of symmetrical shielded cable reduces
electromagnetic emission of the whole drive system as well as motor bearing currents and wear
of bearings.
The motor cable and its PE pigtail (twisted screen) should be kept as short as possible in order
to reduce electromagnetic emission as well as capacitive current.
Motor Cable Shield
To effectively suppress radiated and conducted radio-frequency emissions, the shield
conductivity must be at least 1/10 of the phase conductivity. The requirements are easily met
with a copper or aluminum shield. The minimum requirement of the motor cable shield of the
drive is shown below. It consists of a concentric layer of copper wires with an open helix of
copper tape. The better and tighter the shield, the lower the emission level and the bearing
currents.
Additional US Requirements
Type MC continuous corrugated aluminum armor cable with symmetrical grounds or shielded
power cable must be used for the motor cables if metallic conduit is not used. For the North
American market, 600 VAC cable is accepted for up to 500 VAC. For drives rated over 100
amperes, the power cables must be rated for 70ºC (158ºF).

Conduit
Where conduits must be coupled together, bridge the joint with a ground conductor bonded
to the conduit on each side of the joint. Bond the conduits also to the drive enclosure. Use
separate conduits for input power, motor, brake resistors, and control wiring. Do not run
motor wiring from more than one drive in the same conduit.
Armored cable / shielded power cable
The motor cables can be run in the same cable tray as other 460 V power wiring. Control and
signal cables must not be run in the same tray as power cables. Six conductor (3 phases and 3
ground) type MC continuous corrugated aluminum armor cable with symmetrical grounds is
available from the following suppliers (tradenames in parenthesis):
• Anixter Wire & Cable (Philsheath) • BICC General Corp (Philsheath)
• Rockbestos Co. (Gardex) • Oaknite (CLX).
Shielded power cables are available from Belden, LAPPKABEL (OLEFLEX) and Pirelli.

of cable beyond 100 feet, use screen connections.
Do not directly ground the RS485 network at any point. Ground all devices on the network
using their corresponding earthing terminals.
As always, the grounding wires should not form any closed loops, and all the devices should
be earthed to a common ground.
Terminate the RS485 network using 120 Ω resistors at both ends of the network. Use the DIP
switch to connect or disconnect the termination resistors. See following diagram and table.
1 For functional descriptions, see “Standard Serial Communication” addendum.

Introduction
AQUAVAR CPC drives include an extension module that
is not covered in the AQUAVAR User’s Manual. The exten-
sion module is attached to the drive module at the factory,
which includes fusible disconnect.
This supplement provides the additional extension mod-
ule information required for AQUAVAR drives:
• Additional installation steps and considerations.
• Steps for separating the drive from the extension mod-
ule for drive service access.
• Dimensions for the extension module.
WARNING!
Ignoring the safety instructions can cause injury or death.
Planning
When planning for cable/conduit routing, refer to the AQUAVAR User’s Manual, but note that,
for the AQUAVAR, all connections are routed through the top of the extension module.
Moving the Unit
1. Move the transport package by pallet truck to the installation site.
2. Unpack the transport package.
3. To position the unit, use a lift, connected as shown.
Mounting
Fastening the Unit
See the “Dimensional Drawings” on page 41 for the exact locations
of the mounting points.
1. Use at least four screws – two at the front, two at the back – to attach the unit base plate to
2. Use at least two screws to attach the back of the enclosure to a wall.
There are two holes available at the top of each: the extension module and the drive module.

WARNING!
maintenance on the equipment. Ignoring the safety instructions can cause injury or
death. Note: There are parts carrying dangerous voltages near the OMIO board when the
drive is powered.
Separating the Drive and Extension Modules
The drive module is mounted on a trolley that straddles a pedestal. The following procedure
removes mechanical connections so that the drive module and trolley can roll forward for
service access.
1. Disconnect all power sources from the drive/extension modules
and wait at least 5 minutes for internal capacitors to fully
discharge.
2. Remove all front covers from the drive module.
3. Disconnect the control panel cable.
4. Remove the upper side plate from the drive module if convenient.
5. Remove screws (if any) that fasten the drive module to the wall.
6. Inside the pedestal, toward the rear are screws that attach the
drive bus bars to the pedestal bus bars. The connections are
staggered for easy access using a wrench with an extension.
Remove these screws (6).
Torque when re-assembling:
• R7: M8 (5/16 in) screws, 15…22 Nm (11…16 lb ft)
• R8: M10 (3/8 in) screws, 30…44 Nm (22…32 lb ft)
WARNING! Be careful not to drop screws inside the pedestal.
Loose metal pieces inside the unit may cause damage.
7. The following cables between the drive and the extension
module are split by a connector located at the front of the drive.
Disconnect both cables at this location.
• The power supply cable to the OMIO board.
• The power supply cable to the extensionmodule cooling fan.
note of the terminal colors for use when reconnecting.
9. Carefully remove the cables disconnected in the above steps: Pull
the cables down inside the pedestal and bundle them so that they
will not get damaged or caught in the trolley when the drive mod-
ule is wheeled out.

2. Electrical supply/ motor/ wiring/grounding — check your supply voltage, motor
wiring, transducer wiring, and grounding.
3. Mechanical/Pump/ Rotation — check your pump rotation, rubbing or other mechanical
problems. Pump “run out”.

Single Pump – Submersible Pump Constant Pressure
It is possible to utilize the Aquavar® Centrifugal Pump Controller on commercial/industrial
installation, programming and pipe layout compared to above ground booster pump
set forth by the motor manufacturer (i.e. Franklin Electric). Always consult with the appropriate
motor technical manual for motor compatibility and requirements when using a Variable
Frequency type drives.
NOTE: THE AQUAVAR IS NOT RECOMMENDED FOR RESIDENTIAL WELL APPLICATIONS.
CONSULT CENTRIPRO FOR SUITABLE VARIABLE SPEED CONTROLLERS DESIGNED FOR
RESIDENTIAL WELL PUMPS (e.g. BF15 series).
Service Factor Amps
The submersible pump will sometimes utilize the motor service factor or MAX AMPS.
Therefore, during peak use times, it is recommended to select the appropriate Aquavar based
on the MOTOR MAXIMUM AMPS or service factor amps. Normally, this can be found on
the motor nameplate or the AIM (application, installation manual). This will avoid nuisance
tripping or current overload by the Aquavar. The Aquavar is designed to protect the motor on
overcurrent! Compare the motor max amps with the list of Aquavar models.
NOTE: ALL MOTORS MUST BE THREE PHASE.
Minimum Frequency
Submersible pump motors require a minimum speed or frequency to operate properly.
Because submersible motors use the water to lubricate and cool, they require this minimum
frequency when controlled by a Variable Speed Drive. Franklin has suggested that the
Minimum Frequency is set to at least 30 HZ in the Aquavar. Therefore, it is recommended
to set the Aquavar Minimum Frequency to 30 to 35 HZ (depending on static head) in
programming group 1402. See programming section.
WARNING: FAILURE TO SET THE MINIMUM FREQUENCY FOR SUBMERSIBLE
TURBINE INSTALLATION COULD RESULT IN DAMAGE TO THE PUMP AND/OR
MOTOR.
Tank Sizing
An appropriate size diaphragm tank must be sized for smooth operation. The tank will also
volume in GPM would be recommended.

Load Reactor (Filter)
“spikes” and switching frequencies found in IGBT type drives, especially when the motor leads
exceed 50 ft. Therefore, a load reactor is required when all of the following conditions are met
for ANY type of AC induction motor (above ground or submersible type):
1. Motor cable length from the Aquavar to the motor is more than 50 wire feet.
2. Drive uses IGBT type of switching (which is industry standard and is used by the Aquavar).
If all of the conditions are present above, then it is recommended to wire a LOAD REACTOR
between the Aquavar output (U2, V2, W2) and the motor. Keep the load reactor as close to
the output of the Aquavar for best results. NOTE: See suggested layout drawing and always
Grounding
NOTE: Always follow local codes for wiring and grounding or refer to the National
Electrical Codes.
Submersible installations are susceptible to stray voltage or grounding problems. It is
recommended to ground the transducer shield to the chassis of the Aquavar cabinet and to
check with a meter for any stray voltage from the three phase motor. Each component of the
electrical Aquavar system should have the same grounding point or reference. Always follow
the submersible motor manufacturer’s recommended installation procedures.
NOTES:
✔ Motors used must be three phase, equal to input voltage.
✔ Standard enclosure is rated for NEMA 1 INDOOR USE ONLY. Consult Factory/ Price
pages for outdoor rated enclosures.
✔ Aquavar CPC not for use on RESIDENTIAL WELL PUMP applications. Consult with factory
for appropriate variable speed controller like the BF15.
✔ Input voltage for the Aquavar can be single phase. Use the U1 , W1 and Ground
connections, and derate the drive by 50% from the three phase rating. Example: 230 volt,
three phase 10 HP Aquavar becomes a 5 HP, 230 volt, single phase rated drive.

MultiPump – Constant Pressure Control
Overview
The Aquavar CPC has the ability to connect and control up to four centrifugal pumps, to
form a Multi-Pump, lead-lag and alternating pumping system. This will allow the operator to
the pumps and motors. The Aquavar units will be hard wired together via the RS485 terminals
(29,30,31), and provide communication to maintain a constant pressure to the system. Once
the lead pump cannot maintain a certain pressure and allows a slight pressure drop, the next
a pump or controller fails, the next pump will automatically turn on in its place. Each Aquavar
controlled pump will provide a fully functional lead/lag and automatic alternation system, with
automatic back up control when required.
System Curve - Friction Compensation
It is possible to program the Aquavar to maintain a constant pressure, and compensate for
the friction loss will increase as well. The Aquavar can compensate for this friction loss with
the simple adjustment of the parameter 2202 “VALUE INCREASE”. When each Aquavar unit
enables the pump, it will increase the system pressure by the programmed amount. This
pressure is additive with each additional pump. Therefore, if you set this parameter for 3 psi,
and you initial constant pressure is 50 psi, and you have 4 pumps total: (50 psi + 3 psi + 3
should be enough to overcome your calculated head and friction loss, and to provide constant
pressure at the end of the pipe run. NOTE: This program function is not intended for
substitution of proper pipe layout and sizing according to Hydraulic Institute Standards.
This feature may not work for excessive friction losses!
Pump Sequencing
The Aquavar CPC has the ability to operate in a multiple pump with lead and lag pumps.
Each Aquavar will be given an address then operate as Pump 1, Pump 2, Pump 3 or Pump 4.
When Pump 1 cannot maintain the required system pressure and the speed reaches 60 Hz,
then that will trigger the lag pump to come on and help maintain the set pressure. In order
for the lag pump to turn on, the lead pump must be at full speed (Maximum Frequency)
and programmed system pressure drop must be met (VALUE DECREASE). Each Aquavar
controlled pump will vary its speed according to the demand on the entire system. In a
Duplex System, you could have Pump 1 running at full speed 60 Hz, and Pump 2 running at 50
sequential mode, when called.

Tank Sizing
Similar to the single pump constant pressure system, the multi-pump system should have
a diaphragm or bladder type tank for system cushion. The tank should be rated for the
maximum system pressure, and be sized for 10-25% of the single pump capacity. This is total
tank volume, not drawdown. If you have a triplex system of 167 GPM per pump capacity,
then your tank size should be a minimum of 17 Gallon capacity. Go to the next higher
tank volume if you have a suction lift or ooded suction. The tank provides small
drawdown capacities on drive start up and provides a “cushion” for the entire system at
normal operation and will provide compressibility at shut-down. The tank pressure will greatly
improve system operation. A larger tank is acceptable and sometimes required, just do not

MultiPump – Slave Pump Control
Overview
The Aquavar CPC has the ability to use up to three “dry” relay contacts for constant speed
pumps. When the required demand increases beyond capacity of the variable speed
controlled lead pump, then the FULL SPEED lag pump will turn on. Each relay will be wired
to your constant speed pump starter, sized for the appropriate horsepower and voltage. The
relay outputs located on the terminal control board X1 (SEE DIAGRAM FROM PREVIOUS
PAGE) will actuate when programmed according to the operators desired output. The lag
pumps will turn on when the Aquavar controlled pump cannot keep up to the required
demand. The lag pumps will be operated by across the line starters, and signaled to start
via the Aquavar relays located on terminal’s 19 through 27 of the X1 terminal block. The lag
pumps are referred to as “SLAVE” pumps, because they operate with commands from the
Aquavar controlled “LEAD” pump. The Aquavar controller will actuate the relays, and provide
a time delay for ON/ OFF on each relay.
Pump 1 + lag pump 2 will operate as a lead and lag system. If Pump 1 + 2 cannot maintain
operating in the system. You can operate up to 3 slave pumps, with 1 Aquavar controlled
pump.
NOTE: Each lag pump is controlled by the speed of the lead Aquavar pump, system
pressure drop (value decrease), and a delay time in seconds. Do not set the pressure drop
too close to operating system pressure, or pump cycling will occur!

in the system. When the Aquavar controlled pump, starts to “run out “or cannot meet the
time delay. The Aquavar CPC has up to three contacts that can be used for “SLAVE” operation.
Wiring/ Connection
The relays used for the SLAVE pump control are dry relay contacts, rated for a MAXIMUM
250 VAC or 30VDC, 2 Amps free from inductivity. Minimum is 500 mW (12V, 10mA). Refer to
diagram below, or in APPENDIX section.
Each relay will be wired to a voltage starter DO NOT EXCEED 250 VOLTS AC through each
relay. Each relay is designed for control power only. It is up to the operator to provide
necessary starters, overloads or fuses for each SLAVE pump motor control. Always follow your

SLAVE Pump Sizing/ Piping
It is recommended that each slave pump be sized the same and with the same performance
curve. All necessary check valves, ball valves, or gate valves should be installed in the system
to limit or “choke” each SLAVE pump discharge in order to maintain proper head conditions
and to prevent pressure oscillations or system “hunting”. Follow all recommended Hydraulic
Institute standards for piping size and pipe layout.

Programming Steps
Default settings for each relay are set for NOT USED. Therefore,
the operator will have to access the programming, and go to
GROUP 18 “RELAY OUTPUTS” and set each relay to START
SLAVE. (SEE BELOW FOR DETAILED PROGRAMMING
STEPS.) Each relay is labeled (R01, R02, R03) and can be
programmed to respond based on a drop in system pressure
and delay time in seconds. Therefore, you can control the relay

Locking
The AQUAVAR CPC has three levels of control panel (keypad) locking; LOCAL LOCK,
PARAMETER LOCK and SET POINT LOCK.
• PARAMETER LOCK - In parameter lock, parameters may be viewed, however they cannot
be changed. Starting, Stopping, set point changes and drive fault resets may still be
performed using the keypad. A valid password must be entered in parameter group 10.02.
• LOCAL LOCK - In local lock, starting and stopping, and setpoint changes are prevented.
Resetting of drive faults is still possible and ON and OFF control.
• SET POINT LOCK – When in the “ON“ position, the set-point cannot be changed from the
control panel. This prevents unwanted changes to Aquavar settings.
To change the drive parameters, including 10.03 LOCAL LOCK, the parameter lock must be
opened. To open the parameter lock, go to parameter 10.02 PASS CODE and scroll to the
number 66 and press ENTER. Parameter 10.01 PARAMETER LOCK will read OPEN.
NOTE: If power to the drive is lost [power failure, disconnect, etc…] parameter 10.01
PARAMETER LOCK will automatically reset to LOCKED.
FEATURES

Protect fault, it will stay at minimum speed until the fault is reset.
If a Pump Protect condition exists and CONFIG SPEED MIN is set to MINIMUM FREQ, Aquavar
will try to reset the fault while at minimum speed if parameter 12.02 AUTO RESTART is set to
“ON” and parameter 24.06 ERROR RESET is set for the desired number of attempts. If the fault
has not cleared after the selected number of resets has been attempted, the pump will be
shut down. If parameter 24.06 ERROR RESET = 0, the pump will be shut down upon a Pump
Protect fault.
If parameter 14.03 CONFIG SPEED MIN is set to ZERO “0” (DEFAULT), the drive will stop the
pump for Pump Protect and Secondary Protect faults. The reaction to stop the pump when at
minimum speed can be delayed for up to 1800 seconds by programming parameter 14.04
(Stp Delay Min Spd).
For example, if the MINIMUM FREQ. is set for 35 HZ, and the Stp. Delay Min Spd is
set for 5 seconds, the pump will ramp down to 35HZ and remain at that speed for 5
seconds, then turn off. This is dependent upon the demand decreasing in the system.
Leaks will keep the pump running at slow speeds. Also check for properly seated check
valves and bladder tank pressure.
WARNING! It is not possible to manually set speed or frequency below the
MINIMUM SPEED setting in parameter 14.02

measures the discharge pressure of the pump via the transducer, and compares it with the
minimum allowed system pressure as entered into parameter (2403) PROTECTION LIMIT. If
this parameter is set, then a time delay will need to be set in number of seconds allowed to
run at or below this limit, before shutting down on a fault.

Regulation Mode
The regulation mode can either be NORMAL or INVERSE. The default and more common
selection is NORMAL, where the Aquavar software anticipates an increase in system pressure,
and will decrease speed of the pump based on a rising system pressure. If the regulation
mode is set to INVERSE, the process condition is expected to increase with a decrease in
pump speed.
Parameter Name Value/Range Note(s)
21.01 REGULATION NORMAL (Default) Inverse is normally used for control of
MODE INVERSE suction side systems.
EXAMPLE – If an Aquavar unit is trying to control the level in a suction-side tank or sump, the regulation mode
would be set to INVERSE. As the level in the sump increased, Aquavar would respond by increasing pump speed
to maintain a constant level.

System Curve Compensation
The AQUAVAR CPC system can automatically compensate for system friction losses due to
most pump catalogs to assist in determining the amount of friction loss that can be expected
loss!
The diagram below illustrates a typical system curve in relation to pump speed.
EXAMPLE - If the set point is 150 Ft [65 PSIG
@ 1.0 SG] and the system resistance increase 10 Ft at the maximum ow rate, or roughly 7%
of the set point, parameter 21.08 would be set as “7”.

Test Run
The TEST RUN capability allows the Aquavar system to run periodically if it has been inactive.
The most common circumstance for which Test Run would be applied is when a standby
pump is infrequently used; the test run would allow lubrication of bearings and help verify if
the unit is ready for operation. The TEST RUN DELAY sets the interval that automatic test runs
will occur at.
Test runs are factory programmed for 20 seconds. This duration cannot be changed. If
Automatic test run is selected, the test run is at 50% of maximum speed.
NOTE: Once manual test is selected and the test is complete, parameter 12.03 will return
to NOT SEL.

Tuning, System Pressure
If the pump appears to oscillate in speed [e.g. Hunting], cannot maintain a uniform set point,
or shuts off too quickly or too slowly, the ramp rates and regulation window settings may need
When an operating mode is selected [i.e. Flow, Pressure, Level, etc…], Aquavar engages
factory default settings for the rate that the drive adjusts at to meet the set point demand.
In most cases these settings will not require adjustment. The most common exceptions are
1], or in
temperature/level control applications, where variables such as tank size is unknown. HVAC
When the Aquavar system is adjusting speed to meet the set-point demand, it does so using
four ramp rates; fast acceleration, fast deceleration, slow acceleration, and slow deceleration.
Aquavar characterizes these rates in terms of seconds to meet the set point hysteresis window
maximum value (described later).
NOTE: In speed control mode, there is only fast acceleration and fast deceleration [R1, R2].

or differential pressure ow meters.
FEATURES

Window Setting (Reg Window)
Window [Parameter 13.06 REG WINDOW] is automatically set based upon the operating
modes and instrument type selected during programming. Values may be adjusted in
parameter 13.06.
EXAMPLE: if the Aquavar unit was in pressure control with the set point at 100 psig, the regulation window
would be factory preset at 8% of the set point. This would result in an 8 PSIG window; 4 PSIG above the set point
and 4 PSIG below the set point.
Parameter Name Value/Range Note(s)
13.06 REG 0-100% Constant Pressure = 8%
WINDOW Flow [Direct] = 30%
Suggested settings are above in the notes. Sometimes the REGULATION WINDOW will have to be adjusted to
smooth out the system pressure. Default setting is 8%.
NOTE: If the system pressure drops below or goes above the hysteresis limits (DASHED
lines), then the Aquavar control software will adjust the speed with the fast ramps. This
would occur if you have a rapid demand of water in your system. Normally it takes a few
seconds to level off.

RAMP HYSTERESIS
Ramp hysteresis is the point at which the Aquavar controller changes over from the fast
ramp to the slow ramp. Default values of Ramp Hysteresis are in % of the regulation window.
The values for RAMP HYSTERESIS are automatically selected based upon the control mode
selection made during programming.
EXAMPLE: Using the same example above, the Regulation Window was 8 psig. An 80% ramp hysteresis would
be 3.2 PSIG. Note from the graph, this is 1.6 PSIG on the upper half of the regulation window, and 1.6 PSIG on

tries to attain the set point. If it is too slow, the actual process value may rise well above the
set point. NOTE: AQUAVAR UNITS ABOVE 10 HP, RAMP 1 AND RAMP 2 SHOULD BE SET
FOR AT LEAST 8 – 10 SECONDS.

Diagnostic Displays
The drive detects error situations and reports them using:
• The green and red LED on the body of the drive.
• The status LED on the control panel (if a control panel is attached to the drive).
• The control panel display (if a control panel is attached to the drive).
• The Fault Word and Alarm Word parameter bits (parameters 0310 to 0311).
The form of the display depends on the severity of the error. You can specify the severity for
many errors by directing the drive to:
• Ignore the error situation.
• Report the situation as an alarm.
• Report the situation as a fault.
Red – Faults
The drive signals that it has detected a severe error, or fault, by:
• Enabling the red LED on the drive (LED is either steady on or blinking).
• Setting an appropriate bit in a Fault Word parameter (0305 to 0307).
• Overriding the control panel display with the display of a fault code.
• Stopping the motor (if it was on).
The fault code on the control panel display is temporary. Pressing any of the following buttons
removes the fault message: MENU, ENTER, UP button or DOWN button. The message reap-
pears after a few seconds if the control panel is not touched and the fault is still active.
Flashing Green – Alarms
For less severe errors, called alarms, the diagnostic display is advisory. For these situations,
the drive is simply reporting that it had detected something “unusual.”
The drive signals that it has detected an alarm, by:
• Flashing the green LED on the drive – does not apply to alarms that arise from control
panel operation errors (Alarms 1 to 7).
• Setting an appropriate bit in an Alarm Word parameter (0308 or 0309).
• Overriding the control panel display with the display of an alarm code and/or name.
The alarm messages disappears from the control panel display if/when any of the following
are pressed on the control panel: MENU, ENTER, UP button, or DOWN button.

Main Fan Replacement
The drive’s main cooling fan has a life span of about 60,000 operating hours at maximum
rated operating temperature and drive load. The expected life span doubles for each 10º C
(18º F) drop in the fan temperature (fan temperature is a function of ambient temperatures
and drive loads).
Fan failure can be predicted by the increasing noise from fan bearings and the gradual rise
in the heatsink temperature in spite of heatsink cleaning. If the drive is operated in a critical
part of a process, fan replacement is recommended once these symptoms start appearing.

Capacitors
The drive intermediate circuit employs several electrolytic capacitors. Their life span is at
least 90,000 hours depending on the operating time of the drive, loading and ambient
temperature. Capacitor life can be prolonged by lowering the ambient temperature.
It is not possible to predict a capacitor failure. Capacitor failure is usually followed by damage
to the unit and an input cable fuse failure or a fault trip. Contact your CentriPro authorized
Aquavar CPC distributor or the factory.
Replacing the Capacitor Pack (R7)
Replace the capacitor pack as described in section “Replacing the Fan (R7)” on page 126.
Replacing the Capacitor Pack (R8)
1. Remove the upper front cover and the side plate equipped with control panel mounting slot.
2. Disconnect the discharging resistor wire.
3. Undo the fastening screws.
4. Lift the capacitor pack out.
5. Install the capacitor pack in reverse order to the above.

Cleaning
Use a soft damp cloth to clean the control panel. Avoid harsh cleaners which could scratch the
display window.
Battery
A battery is only used in Assistant Control Panels that have the clock function available and
enabled. The battery keeps the clock operating in memory during power interruptions.
The expected life for the battery is greater than ten years. To remove the battery, use a coin
to rotate the battery holder on the back of the control panel. Replace the battery with type
CR2032.

Sizing
The current ratings are the same regardless of the supply voltage within one voltage range.
To achieve the rated motor power given in the table, the rated current of the drive must be
higher than or equal to the rated motor current.
Note 1: The maximum allowed motor shaft power is limited to 1.5 · ATimes Rated HP. If
the limit is exceeded, motor torque and current are automatically restricted. The function
protects the input bridge of the drive against overload.
Note 2: The ratings apply in ambient temperature of 40º C (104º F).
Derating
The load capacity (current and power) decreases if the installation site altitude exceeds 1000
meters (3300 ft), or if the ambient temperature exceeds 40º C (104º F) or if 8 kHz switching
frequency (parameter 5001) is used.
Temperature Derating
In the temperature range +40º C…50º C (+104º F…122º F) the rated output current is de-
creased 1% for every 1º C (1.8º F) above +40º C (+104º F). The output current is calculated by
multiplying the current given in the rating table by the derating factor.
Example: If the ambient temperature is 50º C (+122º F) the derating factor is
100% - 1%/ºC x 10º C = 90% or 0.90.
The output current is then 0.90 x I2N or 0.90 x I2hd.
Altitude Derating
The derating is 1% for every 100 m (330 feet) above 3300 feet. If the installation site is higher
than 2000 m (6600 feet) above sea level, please contact the factory for assistance.
Single Phase Supply Derating
For 208…240 Volt series drives, a single phase supply can be used. In that case, the derating
is 50%, for the maximum amps and corresponding power rating of the three phase drive at
208-230 Volt input.
Switching Frequency Derating
If the 8 kHz switching frequency (parameter 5001) is used, derate HP and current output to
80%.

Degrees of Protection
Available enclosures:
• IP 21 / UL Type 1 Enclosure. The site must be free of airborne dust, corrosive gases or
liquids, and conductive contaminants such as condensation, carbon dust and metallic par-
ticles. Indoor use only.
• IP 54 / UL Type 12 Enclosure. This enclosure provides protection from airborne dust and
light sprays or splashing water from all directions. Indoor use only.
• UL Type 3R- Enclosures are intended for outdoor use to provide a degree of protection
from falling rain. Undamaged by the formation of ice on the enclosure. May be cooled
by forced air and louvers for vents. This rating is met by placing the drive into a NEMA 3R
Enclosure.
Compared to the IP 21 / UL Type 1 Enclosure, the IP 54 / UL Type 12 Enclosure has:
• The same internal plastic shell as the IP 21 Enclosure.
• A different outer plastic cover.
• An additional internal fan to improve cooling.
• Larger dimensions.
• The same rating (does not require a derating).
• Plastic gasketed cover for keypad.
