Operating Logic: This control continuously
monitors 3-phase power lines for abnormal
conditions. When properly adjusted, the
control will detect:
●
●
●
●
If none of the above conditions are present,
the control will energize the internal relay
and the indicator light will be green. When
any of the above faults are detected, the
indicator light will turn yellow for approxi-
mately 3 seconds warning that the relay is
about to de-energize. After the delay time
the relay will de-energize and the indicator
light will turn red. When the fault is correct-
ed, the monitor will automatically reset by
energizing the relay and the indicator lamp
will be green. Should the fault be corrected
during the delay time, the monitor will not
de-activate the relay and the indicator will
again be green.
Adjustment: Apply 3-phase power with-
in operating range to the monitor (phase
sequence must be observed). Turn adjust-
ment to maximum clockwise position.
Indicator lamp will be illuminated red after
the delay time. Slowly turn counterclock-
wise until indicator changes to green (relay
will activate). If voltage is nominal, setting
should be correct.
Note: If phase sequence is incorrect, the monitor will not activate.
Reverse any two input leads and readjust as described above.
