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.
