NOTICE
Material damage
When a compressor module (STD) is installed,
the compressor's pressure switch can, under
certain circumstances, no longer provide over-
pressure protection.
➯
For compressors that are not equipped with
independent over-pressure detection, we
recommend that a pressure switch be incor-
porated in the compressor fault circuit(s) to
ensure that any local over-pressure condi-
tion will stop the compressor independently
from the DELCOS XL Master.
