For all 3 setting options below, par. 25-10, Compressor Interlock, must be set to
will also depend on the setting in par. 25-06, Fixed Lead Compressor. If set to
pressor 1 refers to the Compressor controlled by relay RELAY1 etc. If set to
refers to the Compressor controlled by the frequency converter only (without any of the build in
relays involved) and Compresso r2 to the Compressor controlled by the relay RELAY1. Variable speed
Compressor (lead) cannot be interlocked.

Interlocks compressor 1 of the Pack Controller when digitally low and issues Warning [W219]. When
inversely interlocked, compressor 1 (the lead compressor) is staging according to the Fixed Speed
Neutral Zone (par. 25-23).
Interlocks compressor 2 of the Pack Controller when digitally low and issues Warning [W219].
Interlocks compressor 3 of the Pack Controller when digitally low and issues Warning [W219]..
