Regular routine monitoring of pressure differential
across air treatment equipment is recommended.
www.air.irco.com X4I System Automation
PRESSURE SENSOR CONNECTION
The pressure sensor connects to terminal X05 of the X4I
terminal PCB using a shielded 18 AWG maximum 2-
conductor cable no more than 330 feet (100 meters) in
length. The transducer threads are BPT. It is the
equivalent of ¼” NPT.
Pressure Sensor Wiring and Location
Wire polarity is important.
IR-PCB INTERFACE MODULE
8
The IR-PCB is designed to interface a compressor with
the X4I using a 7-conductor shielded cable or individual
wires run through grounded conduit no greater than 330
feet (100 meters) in length.
Each compressor in the system must be assigned a
unique identification number from 1 up to the number of
compressors in the system. The identification number
should be clearly indicated on each compressor for
operational reference.
For each compressor utilizing an IR-PCB, connection to
the X4I the signal wires must be made to the correct X4I
terminals for that compressor number. Compressor 1
should be wired to terminal X01 on the terminal PCB,
Compressor 2 should be wired to terminal X02 on the
terminal PCB, etc.
IR-PCB Interface Module
The IR-PCB is a DIN rail mountable module designed to
be installed within the compressor starter enclosure.
Each air compressor must be equipped with a
load/unload regulation system and, if not regulated with
a single electro-mechanical pressure switch, have a
facility for a remote load/unload control with the ability
to accept a volt-free switching contact input for remote
load/unload. Each air compressor must have Auto
Restart capability.
V For variable speed compressor(s) equipped with a
“variable/fixed” digital input function, install a 7-
conductor shielded cable from the IR-PCB to the X4I.
www.air.irco.com X4I System Automation
Consult the air compressor manual or your air
compressor supplier/specialist for details before
installing the X4I.
Each air compressor must be equipped with an
online/offline pressure regulation system capable of
accepting a remote load/unload signal through a volt
free switching contact or a single electro-mechanical
pressure switch.
The IR-PCB accepts a 12V to 250V input voltage detection
system and utilizes universal relay contact control
outputs (250V “CE” / 115V “UL” @ 5A maximum)
integrated directly into the circuits of an air compressor.
The IR-PCB avoids the need for additional relays or
remote inputs. The IR-PCB also acts as an electrical
barrier between the compressor and the X4I providing
protection and voltage isolation.
Consult the X4I Interconnect and Application Guide
prior to the installation of the X4I and the IR-PCB to the
air compressor.
INPUT FUNCTIONS
9
The IR-PCB is fitted with a six-pin terminal, C04, for
compressor monitoring. The IR-PCB uses two inputs,
Ready and Run, to determine compressor status. An
alarm input can be used if compressor warning
indication is available and required. The alarm input is
optional and is not necessary for system operation.
READY INPUT
The ‘Ready’ connection is intended to indicate that the
compressor is in a “started” state, has no alarm condition
that has shut down the compressor, and is ready to
respond to X4I regulation without manual intervention.
0V
+V
READY LAMP
RUN READY
ALARM
C04
Typical Ready Input Wiring
The READY input will accept 12V to 250V ac (50/60Hz)
or dc.
Do not connect a voltage greater than 250Vac/dc to
this input.
This input must be connected to a circuit of the
compressor control system that will be energized when
the compressor is in a started (standby or running)
condition. For example, locate the circuit across the
ready or operating lamp as shown.
The voltage to this input must de-energize when the
compressor is stopped and unavailable to produce air
upon a load signal, or the emergency stop button is
pressed, or when the compressor experiences a fault that
prevents the compressor from running.
When the compressor ready lamp or other control circuit
is energized, the IR-PCB will detect the voltage and signal
the X4I that the compressor is ready and available to
load and produce air when a load request signal is given.
The IR-PCB common input terminal must always be
connected to the neutral, common or 0V line of the
applied input voltage.
READY INPUT, ALTERNATIVE CONNECTION METHOD
In instances where a convenient voltage signal for a
compressor ready condition is not available, the “ready”
input can be connected directly to a constant compressor
control voltage (12V to 250Vac or dc). This will signal the
X4I that the compressor is ready and available at all
times when power is applied to the compressor. The X4I
has a built-in function to determine when a compressor
is not responding, or is in a shutdown condition, even if
the “ready” signal says otherwise. If the X4I requests a
compressor to run/load, but fails to detect a RUN signal
within 60 seconds, the X4I will regard the compressor as
“not ready” and indicate the compressor as not available.
If a RUN signal is reacquired at any time, the X4I will
automatically reset the compressor “not ready” condition
and re-establish control.
F1
+Vac
0Vac
READY
Alternative Ready Signal Connection
Never connect the “Ready” input positive voltage
connection directly to the output of a control system
transformer. Always connect after a fuse or circuit
breaker.
If a normally closed contact of an emergency stop button
is included in the compressor power supply circuit,
connect after the emergency stop button contacts. This
will instantly indicate a compressor “not ready” condition
if the emergency stop button is activated.

Run Signal Circuit
The RUN input will accept 12V to 250V AC (50/60Hz)

Do not connect a voltage greater than 250V to this
input.
12V to 250Vac must be applied to the “run” terminals
when the compressor motor is running.
This input can be connected to the control terminals A1
and A2 (coil) of the main starter contactor of the
compressor. When the compressor control system
energizes the main contactor, the IR-PCB will detect the
voltage across the contactor coil terminals and signal the
X4I that the compressor is running.
Alternatively, if the main contactor coil voltage is greater
than 250Vac, a contactor auxiliary switch can be used to
apply a suitable voltage to the “run” input terminals.

The IR-PCB input common terminal must always be
connected to the neutral, common or 0V line of the
applied input voltage.
WARNING INPUT (OPTIONAL)
The IR-PCB is equipped with a warning input that can be
used to detect warning conditions.
An alarm that stops the compressor, and/or
prevents the compressor from running is determined
from the “run” and “ready” inputs. Warning detection is
optional and is not a requirement.

This input can be connected to the terminals of an alarm
lamp or other accessible part of the control circuit that is
energized when the compressor is in a warning
condition.
If a warning condition is experienced the compressor
warning lamp, or warning circuit, will energize. The IR-
PCB will detect the voltage and signal the X4I that a
warning has occurred. If the compressor has no
accessible warning circuit, or this function is not
required, the IR-PCB alarm terminals can be ignored.
The IR-PCB input common terminal must always be
connected to the neutral, common or 0V line of the
applied input voltage.

www.air.irco.com X4I System Automation
OUTPUT FUNCTIONS
11
The X4I will control the IR-PCB load/unload relay outputs
based on the active system load and unload pressure
setpoints. The IR-PCB load/unload relay contacts can be
used for compressor controllers that have electro-
mechanical pressure switch load/unload regulation.
IR-PCB Internal Output Circuits
The C01 and C02 terminals of the IR-PCB are intended to
control load and unload regulation of the compressor.
PRESSURE SWITCH REGULATION
For air compressors fitted with an electro-mechanical
pressure switch, a six-pin terminal C02 has been
provided to enable connection to a pressure switch that
has a two-wire or three-wire connection.
When connected, the pressure switch can be switched in
and out of circuit automatically. If the X4I is stopped or
experiences a failure or loss of power, pressure control
will automatically revert back to the pressure switch and
the compressor will continue to operate in “local” mode.
The local pressure settings of all compressors in the
system should be set in a cascaded manner such that the
system will operate normally in the event of X4I
inoperability.
The NC (normally closed) and NO (normally open)
terminal references of the IR-PCB are related to internal
connection functions and should not be referenced to the
connections of a compressor pressure switch, which will
generally be in reverse order.
Lethal voltages may be present on the terminals of
the air compressor pressure switch. Isolate the air
compressor power supply before starting any work.

DIGITAL REGULATION CONTROL TERMINAL C01
A 4-pin connector, C01, has been provided for air
compressor controllers fitted with digital inputs allowing
remote pressure regulation control.
This terminal provides volt free contact closure,
referenced to a common terminal pin, for:
• Remote Load Enable (remote/local
pressure regulation control)
• Remote Load (remote load/unload)
• Remote Variable Speed Regulation
Inhibit (remote variable/fixed speed
regulation control)
The “remote load enable” function provides the facility to
change the compressor load regulation from internal
control to a remote switching source (local/remote).
V The “remote variable/fixed” function provides for
multiple variable speed compressor regulation control on
variable speed compressor(s) equipped with this facility.
When using the “Variable/Fixed” function, the “V”
terminal of the IR-PCB must be connected to the
appropriate “V” terminal of the X4I (according to
www.air.irco.com X4I System Automation
compressor number) with an additional wire. Use a 7-
conductor shielded cable in this instance.
Compressors that use electronic pressure detection
but are not equipped with a remote pressure control
enable feature will not automatically revert to local
control if the X4I is stopped or experiences a fault or loss
of power.

The local/remote pressure regulation input and/or
remote load input logic of some electronic pressure
sensor type controllers are reversed. In this instance, the
“pressure switch” outputs (terminal C02) can be used to
establish alternative logic control connections.
For Example:
If the compressor controller “Local/Remote Pressure

remote when closed), but the “Remote Load” input is a
normally closed type (load when open), the IR-PCB
pressure switch terminal contacts can be used to achieve

Do not attempt to utilize “Digital Pressure
Regulation Control” (terminal C01) and the “Pressure
Switch Control” (terminal C02) output connections at the
same time for different products. These two output
functions are internally connected and a short circuit
condition and/or malfunction may result.
The IR-PCB connection examples shown in this manual
are intended to provide a guide for the majority of
compressor control systems in use. Some compressors
have variations in operation and/or function; consult
your compressor supplier/specialist for advice.
SERVICE MAINTENANCE SWITCH
The IR-PCB is equipped with a volt-free input (terminal
C05) that can be used to remove the compressor from
X4I control, without generating a fault condition, during
short-term maintenance or servicing periods.

C05
Service Maintenance Switch Circuit
When the “Service Maintenance Switch” input terminal
pins are connected together using a volt-free switching
contact, the X4I will indicate that the compressor is not
available but will not generate a warning, alarm, or
shutdown condition. The X4I will also remove the
compressor from the sequence strategy and substitute
with an alternative available compressor if necessary.
When the “Service Maintenance Switch” input circuit is
open again, the compressor will automatically be
accepted back in to the sequence strategy and will be
utilized when next required.
The use of a “key switch” is recommended for this
purpose in order to prevent the switch contacts being
inadvertently left in the closed circuit condition after
service maintenance is complete.
DO NOT connect any external voltage source to the
pins of terminal C05.
AUXILIARY INPUT (OPTION)
The X4I is equipped with an auxiliary input at terminals
31 and 32 (X07).
The function of the input is menu selectable and can be
adapted for differing application requirements.

32
Auxiliary Input Circuit
The input is designed to detect a remote “volt-free”
switching contact (rated for a minimum 24VDC @ 10mA).

AUXILIARY OUTPUT (OPTION)
The X4I is equipped with a remote relay contact output at
terminals 33 and 34 (X08).

Auxiliary Output Circuit
The remote output relay contacts are rated for 240V “CE”
/ 115V “UL” @ 5A maximum.
RS485 COMMUNICATIONS
The X4I is equipped with an RS485 network
communications capability using the proprietary
Multi485 protocol.
This can be only used for remote connectivity to
optional X4I expansion networked units and modules
with proprietary Multi485 communications capabilities.

RS-485 Connection Circuit
RS485 data communications and other low voltage
signals can be subject to electrical interference. This
potential can result in intermittent malfunction or
anomaly that is difficult to diagnose. To avoid this
possibility, always use shielded cables, securely bonded
to a known ground at one end. In addition, give careful
consideration to cable routing during installation.
• Never route an RS485 data
communications or low voltage signal
cable alongside a high voltage or 3-
phase power supply cable. If it is
necessary to cross the path of a power
supply cable(s), always cross at a right
angle.
• If it is necessary to follow the route of
power supply cables for a short distance
(for example: from a compressor to a
wall along a suspended cable tray),
attach the RS485 or signal cable on the
outside of a grounded cable tray such
that the cable tray forms a grounded
electrical interference shield.
• Where possible, never route an RS485 or
signal cable near to equipment or
devices that may be a source of
electrical interference. For example: 3-
phase power supply transformer, high
voltage switchgear unit, frequency
inverter drive module, radio
communications antenna.
SECTION 5 — ASSISTANCE
Contacting Technical Support Services or Service Bulletins listed on the IR ServiceNet can provide further assistance if there
are other questions or concerns during Installation and Start-up. Also, additional Application and Compressor Interconnect
Guides will be posted and available on the IR ServiceNet as they are developed and created.

X4I Interconnect To Ingersoll Rand Pressure Switch Controlled Compressors
Refer to the X4I Overview Drawing for the X4I Compressor 2 through 4 X01 to IR-PCB terminal connections
For All Compressors:
Compressors to be connected must have automatic Start / Stop capability .
Drawing Notes For Pressure Switch Controller Machines:
Ensure each compressor is equipped with independent Excessive Pressure Shutdown Switch. An increase in pressure differential across air
treatment equipment can result in excess compressor discharge pressure. See Pages 84 and 85 for an example drawing. In most applications,
the model and type of pressure switch supplied with the compressor can be used as the Excessive Pressure Shutdown Switch. If this is specific
model/type of pressure switch is not readily available, any pressure switch can be utilized as long as it equals or exceeds the specifications of
the pressure switch found on the compressor.
Set the Excessive Pressure Shutdown Switch to “OPEN” 5 PSI less than the maximum discharge pressure recommended by the compressor
manufacturer.
Guidance only; connections may differ with date, model, type, variant, special, custom or concession builds. This information is intended to

X4I Interconnect To Ingersoll Rand Intellisys SGN / SGNe Controlled Compressors
Refer to the X4I Overview Drawing for the X4I Compressor 2 through 4 X01 to IR-PCB terminal connections
For SGN/SGNe Intellisys Controlled Machines:
The SI1 interface (CCN: 42425710) must be used to allow the SGN/SGNe Controller to be sequenced/controlled by the X4I
The 'SEQUENCER' setting of the Intellisys controller must be set to 'ON'.
Auto Restart must be turned 'ON’ to allow the machines to stop in Auto restart when unloaded by the X4I.
The Intellisys must be run in the Online/Offline regulation mode. Do not use Modulation or ACS.
Check the Intellisys software revision level. Always update to the latest revision prior to operation.
Drawing Notes For Nirvana Machines:
Note: The Nirvana Target Pressure “MUST” be set equal to the Midpoint of the X4I pressure control band.
Refer to the X4I Overview Drawing for the X4I Compressor 2 through 4 X01 to IR-PCB terminal connections

X4I Interconnect To Ingersoll Rand Small Reciprocating Air Compressors
Refer to the X4I Overview Drawing for the X4I Compressor 2 through 4 X01 to IR-PCB terminal connections
For All Compressors:
Compressors to be connected must have automatic Start / Stop capability .
Drawing Notes For Pressure Switch Controller Machines:
Ensure each compressor is equipped with independent Excessive Pressure Shutdown Switch. An increase in pressure differential across air
treatment equipment can result in excess compressor discharge pressure. See Pages 84 and 85 for an example drawing. In most applications,
the model and type of pressure switch supplied with the compressor can be used as the Excessive Pressure Shutdown Switch. If this is specific
model/type of pressure switch is not readily available, any pressure switch can be utilized as long as it equals or exceeds the specifications of
the pressure switch found on the compressor.
Set the Excessive Pressure Shutdown Switch to “OPEN” 5 PSI less than the maximum discharge pressure recommended by the compressor
manufacturer.
