PLM9805规格书详情
Description
The PLM Series is a 3-phase voltage monitor that continuously
monitors each of the three phases. Monitors both delta and
wye systems and no connection to neutral is required. The
microcontroller circuit design protects against undervoltage,
voltage unbalance, phase loss and phase reversal. Protection is
assured when regenerated voltages are present.
Operation
The output relay is energized and the LED glows green
when all voltages are acceptable and the phase sequence is
correct. Under and unbalanced voltages must be sensed for a
continuous trip delay period before the relay de-energizes. Reset
is automatic upon correction of the fault condition. The output
relay will not energize if a fault condition is sensed as power is
applied. The LED flashes red during the trip delay, then glows
red when the output de-energizes. The LED flashes green/red if
phase reversal is sensed.
Field Adjustment
Set voltage adjustment knob at the desired operating line
voltage for the equipment. This adjustment automatically sets
the undervoltage trip point. Apply power. If the PLM fails to
energize, (LED glows red) check wiring of all three phases,
voltage, and phase sequence. If phase sequence is incorrect,
the LED flashes green/red. To correct this, swap any two
line voltage connections at the mounting socket. No further
adjustment should be required.
