Setting the Closed Position Limits
Your GTO/PRO® 4000/4200 has two Limit Settings
1) OPEN Limit setting: (Gate in the OPEN POSITION / FACTORY SET NOT ADJUSTABLE) The open limit setting is
the fully open position.
2) CLOSED Limit setting: (Gate in the CLOSED POSITION) To achieve optimum closed position, you are required
to complete the following SEVEN STEPS:
Step 1
Confirm that the power switch is in the ON position, and the gates are in the OPEN POSITIONS.
Step 2
Activate your operators by pressing the entry transmitter button. Your gates should now be moving from the fully open
positions toward their closing position. Prepare to STOP gate by pressing the entry transmitter button again when the first
gate reaches the desired closed position. This step may be repeated until desired close position is achieved. Once the desired
CLOSED position has been achieved, proceed to step 3.
Step 3
With the first gate in the desired closed position. Program the closed limit setting by setting the number 4 DIP switch on the
DUAL MODES switches to the OFF position (if the MASTER gate closed first) or the ON position (if the SLAVE gate
closed first) then PRESS & HOLD the “SET LIMIT" button on the control board for 5 seconds.
Step 4
Press the transmitter button and allow the gates to return to the fully open position. YOUR FIRST GATE’S CLOSED
POSITION LIMIT IS NOW PROGRAMMED.
Step 5
Activate your operators again by pressing the entry transmitter button. Your gates should now be moving from the fully open
positions toward their closing position. The first gate will stop at the spot you just programmed and the second gate will
continue to close until you press the transmitter button again. The optimum CLOSED POSITION for the second gate is when
it closes firmly, without excess tension, against the first gate. This step may be repeated until desired close position is
achieved. Once the desired CLOSED position has been achieved, proceed to step 6.
Step 6
With the second gate in the desired closed position. Program the closed limit setting by setting the number 4 DIP switch on
the DUAL MODES switches to the ON position (if the MASTER gate closed first) or the OFF position (if the SLAVE gate
closed first) then PRESS & HOLD the “SET LIMIT" button on the control board for 5 seconds.
Step 7
Press the transmitter button and allow the gates to return to
