Starter Panel High Limit Thermostat (170 F) trip was detected.
Note: Other diagnostics that may occur as an expected
consequence of the Panel High Temp Limit trip will be
suppressed from annunciation. These include Phase Loss,
Power Loss, and Transition Complete Input Open for Cprsr 1B

Compressor 1A
Special Immediate Latch All
Bad Sensor or LLID Circuit target if no isolation valves,
Compressor target if isolation valves. Design Note: In the case
of manifolded compressors w/o isolation valves, the occurrence
of this diagnostic will also generate a comm loss with the
nonexistent Suction Press Cprsr 1B in order to accomplish circuit
shutdown.

compressors w/o isolation valve option, this diagnostic will occur
with the preceding diagnostic, even though this transducer is not
required or installed.

All
[compressor or
circuit in manual
lockout]
The evaporator pressure dropped below 8 psia (or 5 psia in sftw
prior to Oct '02)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 compressor or circuit is locked out,
the suction pressure transducer(s)associated with it, will be
excluded from causing this diagnostic.
