6.9.8 Compressor Controller (CC) Critical
Fault Lock Outs
Select the “CC LockOuts” tab to view the setup for the CC
critical fault lock outs.
The “Number of Drive Cooling System Alarms In Buffer”
represents the number of times the following alarms have
occurred within the “Moving Window Hold Time” of 30
minutes:
• Anti-start temperature alarm
• Inverter temperature alarm
• Cavity temperature alarm
• SCR temperature alarm
The compressor will continue to operate even if the
aforementioned alarms occur.
However, if any (or a combination of) the aforementioned
alarms occurs more than the allowable “Limit of Alarms in
Buffer”, within the “Moving Window Hold Time” of 30
minutes, then a “Lock Out Fault” occurs and the motor will
trip.
