“WRN - COMP SYSTEM * INHIBIT” - This WARNING indicates the compressor system safety circuit experienced a trip but reset prior to the
exploration of the 60 minute reset time function. If the safety circuit does not reset in 60 minutes it is replaced with a “LOCKOUT - COMPRES-
SOR SYSTEM * TIME OUT” message.
“AUTO RESET - COMPRESSOR SYSTEM * CLEAR” - Whenever there is a compressor safety trip the Primary IPU board initiates the
“COMPR STATUS CLEAR TIME *” timer. The Primary IPU board records the time it takes for the trip to clear. When the fault clears “COM-
PRESSOR SYSTEM * CLEAR” shows the time it took for the fault to clear in the HISTORY buffer.
“LOCKOUT-COMPRESSOR SYSTEM * TIME OUT” – If the “COMPR STATUS CLEAR TIME *” timer reaches 60 minutes a “LOCKOUT -
COMPRESSOR SYSTEM * TIME OUT” is indicated in the HISTORY buffer.
