Step 3: Attach Opener Arm (page 10)
Step 4: Install Closed Position Stop Plates (page 11)
Step 5: Install the Control / Battery Box (page 12)
Step 6: Connect Battery Harness (page 13)

Step 7: Connect the Transformer (page 14) OR Solar Charger (page 21)
Step 8: Remove Push-To-Open Jumper

A. Make sure the control box power switch is OFF.

B. Use small pliers to remove the JUMPER for PUSH-TO-OPEN

applications.

C. Turn power switch ON. The control board is now configured to

push the gate open. (Keep the jumper, as it is necessary if there

is ever a need to convert the opener for Pull-To-Open.)

Step 9: Set the Open Position Limit (Push-to-Open)
The CLOSED limit is when the opener is fully retracted and the gate is

in the closed position. The closed limit setting can only be adjusted by moving the gate bracket. To acheive the optimum

open position, you must adjust the OPEN Limit setting:

A. If not already ON slide the ON/OFF switch on the Control Box to the ON position and make sure the arms are in

the CLOSED POSITION (fully retracted).

B. Press and HOLD the FIRST Opener OPEN button on the control board and be prepared to RELEASE the button

when the gates reached the desired open position/limit. Use the JOG OPEN and CLOSE buttons to "fine tune"

the gate position if neccessary.

C. Press and HOLD the SECOND Opener

OPEN button on the control board and

be prepared to RELEASE the button

when the gates reached the desired

open position/limit. Use the JOG

OPEN and CLOSE buttons to "fine

tune" the gate position if neccessary.

D. NOTE: The opener arms must be

extended more than 7 inches to set

limits. With the gates in in the desired

open positions PRESS and HOLD the

SET LIMIT button until the alarm and

RED Light come on. Then release the

button.

E. NOTE: When the control box cover is removed the receiver range is reduced to less than 5 feet. Press the

transmitter button once and allow the gates to fully close. The alarm will beep once when both gates reach the

CLOSED LIMIT. This indicates the LIMITS for both arms are learned and stored in memory.

F. Press the transmitter button and allow the gates to fully open to verify that they stop at the desired positions.

Repeat Steps B – E if correction is needed.

Note: Must have a transmitter that operates the gate. If not, see Personalize Your Transmitter Setting on page 18.
