Compact 3 Phase Voltage Monitor
TVW 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 microcontroller circuit design that senses under and overvoltage, 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 is de-energized during restart delay.
Under normal conditions, the output energizes after the
restart delay. Undervoltage, overvoltage, and voltage
unbalance must be sensed for the complete trip delay
period before the output de-energizes. The restart
delay begins as soon as the output de-energizes. If
the restart delay is completed when a fault is corrected,
the output energizes immediately. The output will
not energize if a fault is sensed as the input voltage
is applied. If the voltage selector is set between two
voltage marks (e.g. between 220 and 230 V), the LED
will flash red rapidly. The TVW provides fault protection
at the lower of the two line voltages (e.g. 220 V).
Reset: Reset is automatic upon correction of a fault.
Connection
F = 2 A 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. If the voltage selector knob is
between settings, it rapidly flashes red.
