OUTPUT FUNCTIONS

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
