Detected compressor currents greater than 10%
RLA on any or all phases when the compressor
was commanded off. Detection time shall be 5
second 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 Pump Output, continue to command the
affected compressor off, fully unload the effected
compressor and command a normal stop to all
other compressors. For as long as current
continues, perform liquid level, oil return, and fan
control on the circuit effected.

Starter Did Not Transition - xy Cprsr
Immediate
Latch
On the first
check after
transition.
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-Transformer, Primary Reactor, and X-Line
Starters.

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.).

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.

The Transition Complete input was found to be
opened with the compressor motor running after
a successful completion of transition. This is active
only for Y-Delta, Auto-Transformer, Primary
Reactor, and X-Line Starters. To prevent this
diagnostic from occurring as the result of a power
loss to the contactors, the minimum time to trip
must be greater than the trip time for the power
loss diagnostic.
