The respective circuit’s evaporator
pressure dropped below 80% of the
current Low Evap Refrig Press Cutout
setting (see above) or 8 psia, whichever is
less, regardless of the running state of the
circuit’s compressor. Note: Unlike previous
products, even if the circuit associated
with the suction pressure sensor is locked
out, it will not defeat the protection
afforded by this diagnostic.
