184 Phase Reversal -
Compressor 1A
Immediate Latch A phase reversal was detected on the incoming current. On a
compressor startup the phase reversal logic must detect and trip in a
maximum of .3 second from compressor start.

1A0 Power Loss - Compressor 1A Immediate NonLatch The compressor had previously established currents while running and
then all three phases of current were lost. Design: Less than 10% RLA,
trip in 2.64 seconds. This diagnostic will preclude the Phase Loss
Diagnostic and the Transition Complete Input Opened Diagnostic from
being called out. To prevent this diagnostic from occurring with the
intended disconnect of main power, the minimum time to trip must be
greater than the guaranteed reset time of the Starter module. Note:
This diagnostic prevents nuisance latching diagnostics due to a
momentary power loss - It does not protect motor/compressor from
uncontrolled power reapplication. See Momentary Power Loss
Diagnostic for this protection. This diagnostic is not active during the
start mode before the transition complete input is proven. Thus a
random power loss during a start would result in either a "Starter Fault
Type 3" or a "Starter Did Not Transition" latching diagnostic.
