1ED Starter Fault Type II –
Compressor 1A
Immediate Latch a. This is a specic starter test where the Shorting Contactor (1K3) is
individually energized and a check is made to ensure that there are
no currents detected by the CT's. If current is detected when only S is
energized at Start, then 1M is shorted. b. This test in a. above applies
to all forms of starters (Note: It is understood that many starters do not
connect to the Shorting Contactor.).

1F1 Starter Fault Type III –
Compressor 1A
Immediate Latch As part of the normal start sequence to apply power to the compressor,
the Shorting Contactor (1K3) and then the Main Contactor (1 K1) were
energized. 1.6 seconds later there were no currents detected by the
CT's for the last 1.2 Seconds on all three phases. The test above
applies to all forms of starters except Adaptive Frequency Drives.

5BA Suction Refrigerant Pressure
Transducer – Circuit 1,
Compressor 1A
Immediate Latch 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.
