X4I Interconnect To Ingersoll Rand Intellisys SG Controlled Compressors

Refer to the X4I Overview Drawing for the X4I Compressor 2 through 4 X01 to IR-PCB terminal connections

For SG Intellisys Controlled Machines:

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.

For Sierra SG Intellisys Controllers, the SI1 interface (CCN: 42425710) can be used as an alternative to allow the SG Controller to be sequenced/ controlled by the X4I

Drawing Notes For SG Intellisys Controlled Machines:

Note: For Star Delta starter wiring the X4I Run signal should be connected directly to the 1M coil.

Note: For Full Voltage wiring, the 1S (1Sb) interlock will not be used. The X4I Run signal can be connected directly to the Intellisys P1-2 terminal. Refer to the X4I Overview Drawing for the X4I Compressor 2 through 4 X01 to IR-PCB terminal connections

Guidance only; connections may differ with date, model, type, variant, special, custom or concession builds. This information is intended to be used in conjunction with the compressor’s original control circuit diagram.
