Compressor Did Not
Accelerate: Transition -
Compressor 1A
*Circuit Info Latch Start Mode
The compressor did not come up to speed (fall to
<85%RLA) in the allotted time defined by the
Maximum Acceleration Timer and a transition was
forced (motor put across the line) at that time.
This applies to all starter types.

Motor Current Overload -
Compressor 1A
Circuit Immediate Latch Cprsr Energized
Compressor current exceeded overload time vs.
trip characteristic. Must trip = 140% RLA, Must
hold=125%, nominal trip 132.5% in 30 seconds

Phase Loss - Compressor
1A
*Circuit Immediate Latch
Start Sequence and
Run modes
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
= 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 trip point 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 seconds from compressor start.

Phase Reversal -
Compressor 1A
*Circuit Immediate Latch
Compressor energized
to transition command
[All Other Times]
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.
