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
be used in conjunction with the compressor’s original control circuit diagram.
