If however, “Liq. Level HIGH” remains displayed continuously for two (2) minutes the purge
will automatically enter a “Drain Back Equalization Cycle” which can last up to 10 minutes.
Displayed:
Drain Equalizing
Max. Delay : 00:00
(min. & sec. to “Drain Fault”)
If the liquid level switch LS1 senses proper drainage (LS1 contact reopens) anytime during
the 10 minute Drain Back Equalization Cycle the purge unit will automatically resume normal
operation. However, if the liquid level is still “HIGH” at the end of ten 10 minute Drain Back
Equalization Cycle the purge will shut down on “DRAIN FAULT”.
Displayed:
DRAIN FAULT
If the Drain Back Equalization Cycle terminates in less than two (2) minutes the purge unit will
enter a two (2) minute “Compressor Delay” to prevent short cycling the compressor.
Displayed:
Drain Equalizing
Compressor Delay
NOTE: If a DRAIN BACK EQUALIZATION CYCLE should occur during certain timed
operating functions, (such as an adaptive “ON” cycl e) that functions time will
automatically be extended in minute equal to the number of lapsed minutes that
occurred during the drain back equalization cycle.
