Operator Setup
Operator Mounting
The operator mounts on the post bracket pin and into the
gate bracket bushing. Refer to Figure 5.
1. With the gate closed, carefully position the operator over the mounting
brackets.
2. Lower the operator onto the post bracket pin while guiding the
operator’s worm drive traveler shaft into the gate bracket bushing.
3. Install the washer and clip-ring on the post bracket pin.
4. Install the washer and clip-ring on the traveler shaft.
Controller Connection
The APeX Controller is mounted in a sealed NEMA4
enclosure. Open the cover for installation access.
The Controller contains two 5-position plug-in terminal
blocks for connection to one or two LRA operators. Terminal
block MOTOR-1 is used in single gate LRA installations.
Terminal block MOTOR-2 is used for the second arm in dual
gate LRA2 installations.
To make wiring easy, the terminal blocks are removable and
plug into the Controller’s circuit board.
1. Route the operator cable up through the fl uid-tight strain-relief fi tting
on the bottom of the Controller’s cabinet.
2. Noting the wire colors, connect the operator cable to MOTOR-1
Terminals 1-5 on the Controller.
3. Route the cable towards the operator. Be sure to leave enough slack
in the cable to allow for the gate swing.
4. Remove the operator’s wiring access plate (see Figure 6).
5. Cut the cable to length if required, then slide the O-ring over the end
of the cable.
6. Connect the interface cable to the operator’s terminal block matching
the same colors and terminal numbers used in Step 2 (see Figure 6).
7. Replace the operator’s wiring access plate being careful to align the
O-ring below the cable clamp. The O-ring helps keep out moisture.
For dual gate installations, repeat Steps 1-7 and connect the
second operator’s cable to the MOTOR-2 5-position terminal
block in the Controller (see Figure 7). Use the strain-relief
fi tting that comes with the LRA2 kit where the cable enters
the Controller cabinet.
