Operating Modes
These relays can be used as either overvoltage or undervoltage relays, depending on the output contact used:
Overvoltage Relay
Provides protection to equipment that cannot handle excess
voltages. Uses a normally closed contact (N.C.). As long as
the monitored voltage remains below the maximum voltage the
equipment can withstand (Pick-Up Setting), the relay remains
de-energized and the N.C. contact remains closed, keeping the
load energized. If the operating voltage increases beyond the
maximum rating of the equipment, the relay energizes and the
N.C. contact opens, turning off the load. When the voltage
falls below the Drop-Out Setting (hysteresis), the relay de-
energizes and the N.C. contact re-closes, turning on the load.

Indicator LED: Red steady when relay is energized; Green
steady when relay is off; and Green rapid flash when in power-
up mode.
Reset: As standard, reset is automatic upon correction of a
fault.
Approvals:
Undervoltage Relay
Provides protection to equipment that is required to
operate above a certain minimum voltage. Uses a
normally open contact (N.O.). As long as the monitored
voltage is above the minimum value required (Pick-Up
Setting), the relay will energize and the N.O. contact
closes, turning on the load. If the voltage drops below
the Drop-out Setting (the minimum voltage required
minus the hysteresis), the relay will de-energize and the
N.O. contact will re-open, turning off the load.
