APPENDIX Limit Setup with a Remote Control To set the limits using a remote control, first you will need a 3-button remote control that has been programmed for OPEN, CLOSE, and STOP. Refer to the Programming section. Initial Limits and Force Adjustment For dual gate applications the limits will have to be set for each operator. The gate MUST be attached to the operator before setting the limits and force. Ensure the gate is closed. 1. Press and release the SET OPEN and SET CLOSE buttons simultaneously to enter limit setting mode. 2. Press and hold the OPEN or CLOSE button on the remote control until the gate reaches the desired open position. The gate can be jogged back and forth using the OPEN and CLOSE buttons on the remote control. 3. Once the gate is in the desired open position, press and release the STOP button on the remote control. 4. Press and release the OPEN button on the remote control again to set the open limit. 5.
