Operator Setup (Continued)
AC Power Connection
The control box contains a power disconnect switch to turn
on and off the power available to the operator. Following
wiring specifi cations on Page 2, incoming power should be
brought into the control box and connected to the labeled
pigtails from the disconnect box. A wiring connections print
can be found on the label inside the cover of the operator.
See Figure 8 for power option examples.
Earth Ground
Install a ground rod and connect it to the control box in every
installation. A good earth ground is necessary to allow the
Controller’s built-in surge and lightning protection circuitry
to work effectively.
✓ NOTE: Do not splice the ground wire. Use a single piece of solid
copper 12 AWG wire between the ground rod and the control box.
1. Install an 8-foot long copper ground rod within three feet of the
control box.
2. Use a clamp to connect a solid copper 12 AWG ground wire to the
ground rod.
3. Route the ground wire to the control box through a wiring knockout.
4. Connect the ground wire to the screw terminal located above the
115V power receptacle on the Controller’s metal chassis.
Manual Disconnect
In case of a power failure or other condition, the gate can be manually
moved without action from the operator by using the manual disconnect
switch (see Figure 9).
To activate the manual disconnect switch:
1. Open the cover on the switch.
2. Insert the disconnect key (supplied with operator).
3. Turn the key clockwise 90˚.
4. Reverse the steps to re-engage the operator.
Dual Gate Stagger Delay
This feature is used for overlapping dual gates. After completing setup of
the operator, in dual gate installations use the following control to adjust
the dual gate stagger:
To delay opening of Gate 1, and delay closing of Gate 2, gently adjust
the potentiometer located on the motor board (under the small blue
removable cover) clockwise until the desired delay is reached (see
Figure 10). Do not turn more than ¾ of a turn or damage will result.
Range is 0 to 10 seconds delay.
Only Motor-1 can be delayed on open. Plug the appropriate LRA arm
into either the MOTOR-1 or MOTOR-2 terminal block to change which
gate is delayed.
