PLM9502規(guī)格書詳情

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.
