   PHASE MONITORS

  

  3 PHASE VOLTAGE MONITORS
  Required for compliance with National Elevator Code, ANSI/ASME A17.1, Rule 210.6.
  All models UL and CSA approved.

PLR Series
Protects against:
1. Phase loss ( on start up)
2. Low voltage
3. Phase reversal
Octal, 8 Pin Socket Mount
SPDT Isolated Relay Contact
Model SPLR-240   (240V)
Model SPLR-480   (480V)


PLM Series
Protects against:
1. Phase loss
2. Low voltage
3. Phase reversal
4. Voltage underbalance
Octal, 8 Pin Socket Mount
SPDT Isolated Relay Contact
Model SPLM-240   (240V)
Model SPLM-480   (480V)


RLM Series
Protects against:
1. Phase loss
2. Low voltage
3. Phase reversal
4. Voltage underbalance
Model SRLM-240    (240V)
Model SRLM-480    (480V)


The RLM voltage monitor provides the same features as the PLM series, in addition to providing better protection against faults by allowing the accurate adjustments of voltage underbalance, line voltage and trip delay settings via on-board knobs and calibrated dials.The RLM is fully encapsulated for uses under rugged conditions.
