Description
If line voltage falls below the accepted level, the relay output will open
until the line voltage returns to the accepted level. Voltage Drop Protection
conditions comply with AHRI standard 110-2012 Range B. For Voltage
conditions that drop below outside the limits of Range B prompt corrective
action is recommended
•
120 VAC Nominal – Range B 104 VAC
•
208 VAC Nominal – Range B 180 VAC
•
240 VAC Nominal – Range B 208 VAC
Once the line voltage exceeds the pick-up line voltage, the relay will close
after the time delay elapses. Delay = 3 Minutes (non-adjustable).
If surge or voltage monitoring protection is lost, the unit will continue nor-
mal compressor and thermostat operation without surge protection. The
unit should be replaced to restore surge protection to the circuit.
