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.

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.
