DescriptionDescription

Description

DescriptionDescription

Provides protection for motors and other sensitive loads. Continuously measures the voltage of each of the three
phases using a new microcomputer circuit design that senses under and over voltage, voltage unbalance, phase
loss, and phase reversal. Protection is provided even when regenerated voltages are present. Includes a trip
delay to prevent nuisance tripping and a restart delay to prevent short cycling after a momentary power outage.

OperationOperation

Operation

OperationOperation

Upon application of line voltage, the restart delay
begins. The output relay is de-energized during restart
delay. Under normal conditions, the output energizes
after restart delay. Undervoltage, overvoltage, and
voltage unbalance must be sensed for continuous
trip delay period before the output is de-energized.
The output will not de-energize if a fault is corrected
during the trip delay. The restart delay begins as
soon as the output relay de-energizes. If the restart
delay is completed when the fault is corrected, the
output relay will energize immediately.
The output relay will not energize if a fault or phase
reversal is sensed as three phase input voltage is
applied.

The LED flashes green during the restart delay, then
glows green when the output energizes. It flashes
red during the trip delay then glows red when the
output de-energizes. It flashes red/green if phase
reversal is sensed.
