Fine Tune the Force
Once the initial limits have been set, the REVERSAL FORCE DIAL on the
control board is used for fine tuning the force where wind or
environmental changes may affect the gate travel. The REVERSAL FORCE
DIAL is set to minimum at the factory.
Based on the length and weight of the gate it may be necessary to make
additional force adjustments. The force setting should be high enough
that the gate will not reverse by itself nor cause nuisance interruptions,
but low enough to prevent serious injury to a person. The force setting is
the same for both the open and close gate directions.
1. Open and close the gate with the TEST BUTTONS.
2. If the gate stops or reverses before reaching the fully open or closed
position, increase the force by turning the force control slightly
clockwise.
3. Perform the “Obstruction Test” after every limit and force setting
adjustment (see below).
Adjust the Limits
After both limits are set and the operator is ready to run, one limit can be
adjusted independently from the other by following steps 1-3 of the
Initial Limit and Force Adjustment section.
Obstruction Test
The operator is equipped with an inherent (built in to the operator)
obstruction sensing device. If the gate encounters an obstruction during
motion, the operator will reverse direction of the gate and then stop. The
following procedure will test ONLY the inherent (built in to the operator)
obstruction sensing device:
1. Open and close the gate with the TEST BUTTONS, ensuring that the
gate is stopping at the proper open and close limit positions.
2. Place an object between the open gate and a rigid structure. Make
sure that any external entrapment protection devices will NOT be
activated by the object.
3. Run the gate in the close direction. The gate should stop and reverse
upon contact with the object. If the gate does not reverse off the
object, reduce the force setting by turning the force control slightly
counter-clockwise. The gate should have enough force to reach both
the open and close limits, but MUST reverse after contact with an
object.
4. Repeat the test for the open direction.
Test the operator after any adjustments are made.
