Very Low Suction Pressure – Circuit 2
Very Low Suct Press – Ckt 2
Chiller Immediate Latch
All
[circuit in manual
lockout]
The circuit’s suction pressure dropped
below (Low Pressure Cutout Setpoint
(kPa absolute) * 0.5)
regardless of whether or not
compressors are running on that
circuit. This diagnostic was created to
prevent compressor failures due to
crossbinding by forcing an entire chiller
shutdown. If a given circuit is locked
out, the suction pressure transducer
associated with it will be excluded from
causing this diagnostic.
