SECTION 4  COMPRESSOR CONNECTION AND CONTROL
COMPRESSOR CONNECTION AND
CONTROL
Each air compressor in your system must be interfaced to
the X8I. Interface methods may vary depending on the
compressor type and/or local control configuration. The
following are main methods for interfacing compressors
to the X8I:
1) The ir-PCB Interface module that is designed to
interface to any positive displacement air compressor
(regardless of make or manufacturer) with an available
control voltage of 12-250V (either 50Hz or 60Hz).
The ir-PCB interface module is installed within the
compressor control area and connected to the X8I using
a six (6) wire cable, (seven (7)-wire cable for Nirvana 7.5 to
15HP (5.5 to 11KW).
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.
Consult the air compressor manual or your air
compressor supplier/specialist for details before installing
the X8I.
2) The ir-485 Gateway Interface module that is designed
to interface to any Ingersoll Rand Intellisys controlled
(Non-Nirvana) compressor. The X8I communicates to the
ir-485 Gateway via a two wire, RS485 network utilizing the
ir485 protocol. All IR compressors equipped with Intellisys
controllers (Non-Nirvana) require this interface.
All Nirvana Compressors, 20 HP (15KW) and above
require the irV-485 Gateway.
ir-485
The ir-485 Gateway interface module is installed within
the compressor control cabinet and connected to the X8I
using Belden 9841 or equivalent RS485 cable.
3) The irV-485 Gateway Interface module that is
designed to interface to any Ingersoll Rand Nirvana
compressor. The X8I communicates to the irV-485
Gateway via a two wire, RS485 network utilizing the ir485
protocol. All Nirvana Compressors, 20 HP (15KW) and
above, require this interface.
ir - 485
The irV-485 Gateway interface module is installed within
the compressor control cabinet and connected to the X8I
using Belden 9841 or equivalent RS485 cable.
Nirvana 7.5 to 15HP (5.5 to 11KW) connect via the
ir- PCB using seven (7)-wire cable.
4) Direct Connect via RS485 to any Ingersoll Rand
compressor that has an integrated RS485 network port
utilizing the ir485 protocol. The X8I communicates to
these compressors via a two wire, RS485 network. The
compressor is connected to the X8I using Belden 9841 or
equivalent RS485 cable.
4) Special Application Interface uses integration boxes
designed to accommodate various types of compressor
and regulation methods and system monitoring.

OPTIONAL CONNECTION METHODS

Expansion Module: EXP Box (Option)
As standard the X8I has four direct connect 'ir-PCB'
terminal connections. This capability can be extended
with the use of an optional EXP Box. The EXP Box will add
another four direct connect 'ir-PCB' connection terminals.
This would allow a total of 8 compressors to connected
and controlled via 'ir-PCB' integration.
Compressors 1-4 connect via the X8I and Compressors 5-8
connect via the EXP Box
The EXP Box is suitable for wall mounting and must be
located adjacent to the X8I unit (max 33ft or 10m).

The EXP Box connects to the X8I controller via a two wire,
dedicated RS485 network
Use Belden 9841 or Equivalent In Grounded Conduit
No Greater Than 33ft (10m)
Up to four air compressors can be connected to the EXP
Box using a 6 or 7 wire cable and a compressor interface
ir-PCB (330ft (100m) max). The 'ir-PCB' connections are
identical to the X8I.
