Compact 3 Phase Voltage Monitor
TVM Series The Net
Motor Protector
Description
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.
Operation
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.
Reset: Reset is automatic upon correction of a fault.
Connection
Relay contacts are isolated. Dashed lines are
internal connections.
F = 2A Fast Acting Fuses are recommended,
but not required.

LED Operation
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.
