Adjust The Handing And Limits - Chamberlain LiftMaster CSW200101U Installation Manual

To reduce the risk of SEVERE INJURY or DEATH:
• Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a moving gate.
• Too much force on gate will interfere with proper operation of safety
reversal system.
• NEVER increase force beyond minimum amount required to move
gate.
STEP 10

ADJUST THE HANDING AND LIMITS

The adjustments allow you to set where the gate will stop in the open and close position. The force is adjusted automatically when you set the limits
but should be fine tuned using the FORCE dial on the control board (refer to Force Dial section). The Test Buttons on the control board will not work
until the handing is set. For dual gate applications the limits will have to be set for each operator. The gate MUST be attached to the operator before
setting the limits and force.
OPEN RIGHT: If the operator is installed on the right side of the driveway when looking out of the property, the gate should be set to open right.
OPEN LEFT: If the operator is mounted on the left side of the driveway when looking out of the property, the gate should be set to open left.
SET THE HANDING
1. To set the initial handing of the operator, make sure that both OPEN LEFT and OPEN RIGHT LEDs are flashing. If they are not flashing, press and
hold both the OPEN LEFT and OPEN RIGHT handing buttons until both handing LEDs start to flash and the operator beeps.
2. Press and release either the OPEN RIGHT or OPEN LEFT button depending on which direction the gate should open. The corresponding handing
LED will turn solid.
SET THE LIMITS
1. Make sure the gate is closed.
2. Press and release the OPEN test button to open the gate.
3. Press the STOP test button when the desired OPEN limit is reached. Adjust the
limit nut or cam so it makes contact with the OPEN limit switch at this position.
If the gate stops early, move the limit nut or cam to allow for additional travel.
4. Press and release the CLOSE test button to close the gate.
5. Press the STOP test button when the desired CLOSE limit is reached. Adjust the
limit nut or cam so it makes contact with the CLOSE limit switch at this position.
If the gates stops early, move the limit nut to allow for additional travel.
SET THE FORCE AND RUN DISTANCE
1. Press the OPEN test button to open the gate.
2. Press and release both the OPEN LEFT and OPEN RIGHT handing buttons.
3. Press the handing button below the solid LED.
4. Run the operator one full cycle using the test buttons. The initial forces and run
distance will be set during this cycle.
READJUST THE LIMITS
To readjust the limits, follow the "Set the Limits" and "Set the Force and Run
Distance" instructions above. It is important that the force and run distance are
set after every limit readjustment.
INSTALLATION
• NEVER use force adjustments to compensate for a binding or
sticking gate.
• If one control (force or travel limits) is adjusted, the other control
may also need adjustment.
• After ANY adjustments are made, the safety reversal system MUST
be tested. Gate MUST reverse on contact with a rigid object.
