G / E-Series Regular Specification

    Product Features:

    • Front button for resetting in manual mode
    • External potential free (zero volt /no voltage) terminal contacts for auto mode.
    • LED indication for relay status
    • Window displays the type of fault that has occurred during unhealthy condition
    • Trip delay time and limits for each parameter can be set digitally
    • All programs can be locked by removing short link across specified terminals
    • Unwanted parameters can be by-passed as per user’s choice.
    • Relay can be configured to have NO or NC status during healthy condition
    • Unit will retain fault till accepted in manual mode
    • PVMD, PVMD-G : Monitors and trips the circuit after the set trip delay time when ever power unhealthiness (phase failure, phase sequence, phase unbalance under voltage or over voltage) occurs.

    Hints on correct use:

    Tools and Fasteners Kindly use star – type screw driver for tightening the screws.
    NOTE: Installation should include a disconnecting device, like switch or circuit breaker, with clear ON/OFF markings, to turn-off the auxiliary
    supply (control power).The disconnecting device should be within the reach of the equipment and the operator.

    Caution:

    • Apply appropriate personal protective equipment(PPE) and follow safety work practices
    • Only qualified electrical workers should install this equipment. Such work should be performed only after reading this entire set of instructions.
    • If the equipment is not used in the manner specified by the manufacturer, the protection provided by the equipment may be impaired.
    • NEVER work alone.
    • Turn OFF all power supplying the energy meter and the equipment in which it is installed before working on it.
    • The successful operation of this equipment depends upon proper handling, installation and operation. Neglecting fundamental installation requirements may lead to personal injury as well as damage to electrical equipment or other property.
    • NEVER bypass external fusing.
    • NEVER apply the voltages at Program Lock and Auto Reset terminals.
    • Before performing Dielectric or Megger testing on any equipment in which the monitoring device is installed, disconnect all the input and output wires to the monitoring device. High voltage testing may damage electronic components contained in the monitor
    • The monitoring device should be installed in a suitable electrical enclosure.
    • EAPL is not responsible for any consequential damages arising out of use of our products, though the technology is cautiously chosen and implemented like any other well designed good electric device.
