Operation & Adjustments of Line Voltage Monitor
MODE OF OPERATION
Upon application of power to the Line Voltage Monitor, and provided all voltages and line conditions are acceptable,
the green “Load Energized” LED indicator will glow. This is an indication that the output contacts have successfully
transferred.
Should a High/Low voltage condition exist for longer than the 5 seconds, or a loss of power for more than 50
milliseconds, the relay and green LED shall be de-energized. The red status LED will rapidly flash. Reset is automatic
upon correction of the fault condition, after the anti-short cycle time delay is complete. The recommended setting for
the time delay is 10 seconds. Should a fault condition exist upon application of power, whether it is on initial
installation or trying to recycle after a fault, the relay will not energize and the red status LED will flash rapidly
indicating power is outside specifications. A blinking status LED indicates power is good; but unit is still in Anti-Short
Cycle (ASC) lockout
ADJUSTMENT
Check power supply with volt meter, and then select the desired operating voltage. If status LED blinks once per
second, voltage is within specification and unit is awaiting the end of the ASC delay. If the red status LED rapidly
flashes red, adjusting input voltage knob higher or lower should cause a slow blink to result. Once input voltage is
properly set, adjust ASC Time Delay knob to desired ASC delay (10 seconds)
LED STATE INDICATIONS
Load energized OFF Internal relay is de-energized
Load energized ON Internal relay is energized
Status OFF Voltage is within range
Status BLINK Voltage in range, unit in ASC
Status FLASH RAPIDLY Voltage is out of range
NOTE: Both LED’s off indicated no power to unit.
