Danger
When a compressor module (STD) is installed, the
compressor's pressure switch can no longer
provide over-pressure protection. For compressors
that are not equipped with independent over-
pressure detection, we recommend that a pressure
switch be incorporated in the compressor fault
circuit(s) to ensure that any local over-pressure
condition will stop the compressor independently
from the GD Pilot TS Master.
