a) No current was sensed on one or two of the current transformer
inputs while running or starting (See Nonlatching Power Loss
Diagnostic for all three phases lost while running). Must hold =
Start 20% RLA. Must trip = 5% RLA. Time to trip shall be longer than
guaranteed reset on Starter Module at a minimum, 3 seconds
maximum. Actual design trippoint is 10%. The actual design trip
time is 2.64 seconds. b) If Phase reversal protection is enabled
and current is not sensed on one or more current xformer inputs.
Logic will detect and trip in a maximum of 0.3 second from
compressor start

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.
