CC Starter Contactor Interrupt
Failure - Compressor 2A
Special
Mode
Latch 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
and fan control on the circuit effected.

180 Starter Did Not Transition –
Compressor 1A
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 YDelta, Auto-
Transformer, Primary Reactor, and X-Line Starters.

1E9 Starter Fault Type I –
Compressor 1A
Immediate Latch This is a specic starter test where 1M(1K1) is closed rst 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 rst at start, then one of
the other contactors is shorted.
