188 Starter Dry Run
Test
Immediate Latch While in the Starter Dry Run Mode either 50 % Line
Voltage was sensed at the Potential Transformers or
10 % RLA Current was sensed at the Current Trans-
formers.

Latch Detected compressor currents greater than 10%
RLA on any or all phases when the compressor was
commanded off. Detection time shall be 5 seconds
minimum and 10 seconds maximum. On detection
and until the controller is manually reset: generate
diagnostic, energize the appropriate alarm relay,
continue to energize the Evap and Cond Pump
Outputs, continue to command the affected
compressor off, fully unload the effected
compressor. For as long as current continues,
perform liquid level and oil return gas pump control

F0 Starter Did Not
Transition
Immediate Latch The Starter Module did not receive a transition
complete signal in the designated time from its
command to transition. The must hold time from
the Starter Module transition command is 1 second.
The Must trip time from the transition command is 6
seconds. Actual design is 2.5 seconds. This
diagnostic is active only for Y-Delta, Auto-Trans-
former, Primary Reactor, and X-Line Starters.

6A3 Starter Failed to
Arm/Start
Info Latch Starter failed to arm or start within the allotted time
(15 seconds).
Remote
1E9 Starter Fault Type
I
Immediate Latch 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.
Local
1ED Starter Fault Type
II
Immediate Latch 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.).
Local
1F1 Starter Fault Type
III
Immediate Latch 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.
