VS94 Time-Delay Adjustment
1. Apply power to the time-delay circuit. (See Electrical for the time-delay circuit). The
time-delay function is initiated.
2. Time the length of the delay with a watch. Let time delay expire. After it expires, the
override circuit will de-energize the solenoid, allowing the latch to trip. A clicking noise is
heard.
WARNING: REMOVE ALL POWER BEFORE OPENING ACCESS DOOR.
IT IS YOUR RESPONSIBILITY TO HAVE A QUALIFIED PERSON
ADJUST THE UNIT AND MAKE SURE IT CONFORMS TO NEC AND
LOCAL CODES.
3. TURN THE POWER OFF TO RESET THE TIME-DELAY CIRCUIT.
NOTE: Allow 30 seconds bleed time between turning the
power OFF and ON.
4. Locate the time adjustment pot (DETAIL C). The time is factory-
set at the lowest setting (approx. 5 seconds). To increase time,
rotate the 20-turn pot clockwise as needed (approx. 5 seconds
per turn).
5. Repeat the above steps as necessary to obtain desired time
delay.
NOTE: An external time delay can be used with the
remote reset feature of the VS2EXR series to provide a
remote reset and override of the trip operation on startup. Time delay must
automatically disconnect after equipment startup.
NOTE: The remote reset solenoids are for momentary use. They are not
rated for continuous operation. Continuous operation will damage the
solenoids and void the warranty.
