The garage door opener is designed with an automatic mechanical |
|
|
|
“Latch” | |||
locking system. This lock secures the door in the fully closed |
|
|
|
position. |
|
|
|
To adjust, activate your opener and allow the door to go to its |
|
|
|
fully closed position. Loosen the two screws on the rail stop and |
|

between “stop” and “latch”. |

Checking the Travel Timer |
|
|
|
Your opener is shipped with the jumper disconnected, allowing the operator to run continuously for up to 29 seconds, then stop in the Open cycle or reverse in the closing cycle.
If your unit will run for only 17 seconds, the operator has mistakenly been shipped with the jumper intact on the control board (perhaps the control board was replaced with a board that still has the jumper installed). On all doors having over 9 feet of travel, it is necessary to cut the run timer jumper on the motor control board to allow the opener to run for 29 seconds. Disconnect the power from the opener before removing cover and cutting the jumper. MAKE SURE YOU DISCONNECT THE POWER BEFORE CUTTING THE JUMPER. THE RUN TIMER WILL NOT CHANGE IF THE JUMPER IS CUT WITH THE POWER CONNECTED.
This jumper is located under operator cover on the control board, as illustrated.
