Alarm Output

Alarm terminal is output connection for applications

where alarm signal is desired. This terminal is powered

whenever compressor is locked out due to HPC or LPC

sequences as described.

NOTE: Both high and low pressure switch controls are

inherently automatic reset devices. The high

pressure switch and low pressure switch cut

out and cut in settings are ﬁxed by speciﬁc

air conditioner or heat pump unit model. The

lockout features, both soft and manual, are a

function of the Compressor Control Module.

Adjustments

Adjustable Delay-on-Make and Delay-on-Break Timer

The potentiometer is used to select Delay-on-Break

time from 30 seconds to 5 minutes. Delay-on-

Make (DOM) timing on power-up and after power

interruptions is equal to 2 minutes plus 10% of Delay-

on-Break (DOB) setting:

0.5 minute (30 seconds) DOB = 123 second DOM

1.0 minute (60 seconds) DOB = 126 second DOM

2.0 minute (120 seconds) DOB = 132 second DOM

3.0 minute (160 seconds) DOB = 138 second DOM

4.0 minute (240 seconds) DOB = 144 second DOM

5.0 minute (300 seconds) DOB = 150 second DOM

Phase Monitor

All units with three phase scroll compressors are

equipped with a three phase line monitor to prevent

compressor damage due to phase reversal.

The phase monitor in this unit is equipped with two

LEDs. If the “Y” signal is present at the phase monitor

and phases are correct, the green LED will light.

If phases are reversed, the red fault LED will be lit and

compressor operation is inhibited.

If a fault condition occurs, reverse two of the supply

leads to the unit. Do not reverse any of the unit factory

wires as damage may occur.
