FINE TUNE THE FORCE

The REVERSAL FORCE DIAL on the control board is used for fine tuning 
the force in cases where wind or environmental changes may affect the 
gate travel. 

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 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, on page 27.

The operator is equipped with an automatic obstruction sensing feature. 
If the gate encounters an obstruction during motion, the operator will 
automatically reverse direction of the gate for a short time and then stop 
the gate. After any adjustments are made, test the operator: 

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 a solid object between the open gate and a rigid structure. 

Ensure that the gate, the solid object, and the rigid structure can 
withstand the forces generated during this obstruction test.

3.   Run the gate in the close direction. The gate should stop and reverse 

upon contact with the solid object. If the gate does not reverse off 
the solid 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 a solid object.

4.   Repeat the test for the open direction.
