WIRING » SET THE LOCK/BIPART DELAY (MODEL LA412-S ONLY) SET THE LOCK/BIPART DELAY (MODEL LA412-S ONLY) Occasionally in dual gate installations, one gate will need to open first and close second. This would happen if there was an ornamental overhang on one gate or if using a solenoid lock, for example. This gate is called the Primary gate and needs to be connected to Gate 1 connections on the control board. Thus, it is preferred that the control box be installed on the same side as this gate. If there is no appropriate location on that side for the control box, then mount the control box on the opposite side, but connect the operator closest to the control box to the Gate 2 connector and the operator on the opposite side to the Gate 1 connector. NOTE: The gate with the longer travel span (opening) must be set as the primary gate (GATE 1). 1 The LOCK/BIPART DELAY switch on the control board needs to be set to the ON position. The following illustration shows a dual gate configuration with a decorative overlapping piece on the outside of the gate. If a solenoid lock is being used on a gate, the gate with the lock attached to it is the primary gate. 1 ON OFF LOCK/ BIPART DELAY C7Ø C71 OUTSIDE PROPERTY Primary Gate - Connect to Gate 1 Connector on Control Board.
