"Remote On-Load" digital output
Do not use this output to switch the compressor on
and off.
This output switches the compressor to On-Load.
This remote On-Load signal should be active
when the programmable output "
Enable Remote
On-Load
" is sent to the compressor controller.
"Remote Partial On-Load" digital output
This output is not used for this application.

NOTICE
Property damage
If a compressor module (STD) is installed, the
pressure switch on the compressor may no
longer provide any protective against overpres-
sure.
➯
For compressors that are not equipped with
an independent overpressure detection
system, it is recommended that a pressure
switch be integrated in the fault circuit of the
compressor, so that any local overpressure
situation will stop the compressor indepen-
dently of the GD PILOT TS master.
