Test
NonLatch
Detected compressor currents
greater than 10% RLA on any or
all phases when the
compressor was commanded
off. Detection time shall be 5
second minimum and 10
seconds maximum. On
detection and until the
controller is manually reset:
generate diagnostic, energize
the appropriate alarm relay,
continue to energize the
Evaporator Pump Output,
continue to command the
affected compressor off, fully
unload the effected compressor
and command a normal stop to
all other compressors. For as
long as current continues,
perform liquid level and fan
control on the circuit effected.
