CONTROL WIRING

If the gate operator is already factory equipped with battery 
run, only the Right/Left Side switch and Mode 1 are supported 
(Figure 3). The Right/Left switch must to be set in the same 
position as the Right/Left switch on the main control board. 
(See page 22 for correctly setting the Right/Left switch on the 
control board.) Gate will continue to operate when power is lost.

If the gate operator did not come from the factory equipped with 
battery run, field installation of battery run is very simple. The 
illustration at right shows additional wiring required for battery 
run that is not part of the standard wiring (Figure 4).

1.  Disconnect power to gate operator.

2.   Disconnect the brown and red wires from terminals 13 and 

14 and insulate the ends of the wires.

3.   Secure the charger board to the main control board by 

attaching to the 14 screw terminal on the left side of the 
control board.

4.   Connect a green wire from terminal 2 to terminal 15 of the 

control board.

5.   Attach an orange wire from terminal D of the charger board 

to terminal 18 of the main control board.

6.   Attach a red wire from terminal A to battery positive and a 

black wire from terminal B to battery negative.

Disconnect these 
existing wires 
from 13 and 14.

(Set same as RIGHT/LEFT 
switch on control board.)
