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.
After any limit adjustment:
1. Cycle the gate open and close to automatically relearn the forces.
2. Perform the Obstruction Test, see page 23.
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. Either place an object between the open gate and the fixed closed
catch post or obstruct the gate by hand. Make sure that any external
entrapment protection devices, such as an edge or photoelectric
sensor will NOT be activated by the object or by hand.
3. Run the gate in the close direction. The gate should stop and
reverse upon contact with the object or hand. If the gate does not
reverse, 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 or hand.
4. Repeat the test for the open direction.
Test the operator after any adjustments are made.
