Starter Fault Type I -
Compressor 1A
Cprsr Immediate Latch
Starting - Y
Delta
Starters Only
This is a specific starter test where 1M(1K1) is closed first and a
check is made to ensure that there are no currents detected by
the CT's. If currents are detected when only 1M is closed first at
start, then one of the other contactors is shorted.

a. This is a specific 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.).

Starter Fault Type III
- Compressor 1A
Cprsr Immediate Latch
Starting
[Adaptive
Frequency
Starter Type]
As part of the normal start sequence to apply power to the
compressor, the Shorting Contactor (1K3) and then the Main
Contactor (1K1) 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.
