Pressure Sensor Connection; IrPcb Interface Module - Ingersoll Rand X8I Mode D'emploi

PRESSURE SENSOR CONNECTION

The pressure sensor connects to terminal X05 of the X8I
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.
Wire polarity is important.
Pressure Sensor Wiring and Location
IRPCB INTERFACE MODULE
The ir-PCB is designed to interface a compressor with
the X8I using a seven (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 X8I the signal wires must be made to the correct
X8I 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.
Cable Earth Shield
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.
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 X8I providing protection and voltage isolation.
prior to the installation of the X8I and the ir-PCB to the air
compressor.
