Dual Sense Stall Force Setting

Do not use the Dual Sense Stall Force adjustment to compensate for a gate that is sticking or binding. Excessive Stall force may

cause damage to the gate operator or gate system.

The Stall Force adjustment controls the amount of force the opener will apply against an obstruction before it stops and reverses

direction. The controller includes three Stall Force settings, and is preset from the factory to Low. If your operator stops and

reverses during a normal cycle, follow the instructions below to change the Stall Force setting.

Adjusting the Stall Force:

1. Press and hold the (UP Arrow) and (DOWN arrow) buttons until the buzzer sounds (approximately 2 seconds). Release.

2. Use the (UP arrow) or (DOWN arrow) to adjust the Stall Force setting. LED1, 2, & 3 are used to indicate the setting. LED3

ON indicates LOW, LED3 & 2 ON indicates MEDIUM, and LED1, 2 & 3 ON indicates HIGH.

3. Press and release the (return/enter) button to set the Stall Force setting.
