3.4 Limit Switch Adjustment
The limit switches on this actuator are adjustable to allow you to control the travel of the gate and to
precisely set the full open and full closed position of the gate. This feature is especially useful in
applications where the gate opens only partially, such as on a curved driveway. Figure 20 shows the
maximum amount of adjustment for each of the limit assemblies.
1. To adjust the limit switches, the actuator must be installed on the gate and power to the
circuit board must be ON.
2. Use the release key and place the actuator in manual operation (See 4.3).
3. Manually move the gate to the desired open position.
4. Loosen the small screw on the limit assembly being adjusted and slowly slide the
assembly until the LIMIT LED on the circuit board illuminates.
5. Tighten the screw to lock the limit assembly in place.
6. Repeat these steps for the slave operator.
7. Manually move the gate to the desired close position.
8. Loosen the small screw on the limit assembly being adjusted and slowly slide the
assembly until the LIMIT LED on the circuit board illuminates.
9. Tighten the screw to lock the limit assembly in place.
10. Repeat these steps for the slave actuator.
11. Use the release key to relock the actuator into normal operation.
