Phase Monitors CM-PVN
Phase Monitors
CM-PVN
Description
Adjustable over and under voltage set points. The CM-PVN is used to monitor three phase supply voltages for
phase reversal, over and under voltage, and phase loss. The output relay is energized as long as the voltages are
in the adjustable acceptable range.

When a voltage exceeds the adjustable overvoltage set point, or falls below the adjustable overvoltage set point,
the isolated DPDT relay de-energizes either immediately or after a trip delay. The LEDs indicate the type of fault. The
CM-PVN automatically resets when the voltage returns to normal, plus a fixed 5% hysteresis. The CM-PVN sense
phase loss by sensing low average voltage. Phase loss may not be detected if regenerated voltage is present.
d
The trip delay function is switch selectable. It can be an ON-delay (delayed energization) or a trip delay (delayed
de-energization). The time delay is adjustable from 0.1 to 10 seconds.
e
On-delay: If the ON-delay type is selected, the output relay does not energize until the voltages remain in the correct
voltage range for the full ON-Delay time. The output relay de-energizes immediately when a fault is sensed.

Trip delay: Upon application of the supply voltage, the output relay energizes. If the voltage reaches an acceptable
range before the time delay is complete, the output remains energized. Each time the voltage exceeds the
acceptable range, the trip delay begins. If the voltage exceeds the acceptable range for the full trip delay, the
output de-energizes.
