Adjustment; Limit And Force Adjustment - Chamberlain RSW12U Installation Manual

LIMIT AND FORCE ADJUSTMENT

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.
INTRODUCTION
Your operator is designed with electronic controls to make travel limit
and force adjustments easy. The adjustments allow you to program
where the gate will stop in the open and close position. The electronic
controls sense the amount of force required to open and close the gate.
The force is adjusted automatically when you program the limits but
should be fine tuned using the REVERSAL FORCE dial on the control
board (refer to Fine Tune the Force section) to compensate for
environmental changes. The limit setup LEDs (located next to the SET
OPEN and SET CLOSE buttons) indicate the status of the limits, refer to
the table to the right.
The limits can be set using the control board (below) or a remote control
(refer to Limit Setup with a Remote Control in the Additional Features
section). Setting the limits with a remote control requires a 3-button
remote control programmed to OPEN, CLOSE, and STOP.
NOTE: The Test Buttons on the control board will not work until the limits
have been set.
INITIAL LIMITS AND FORCE ADJUSTMENT
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.
1. Press and release the SET OPEN and SET CLOSE buttons
simultaneously to enter limit setting mode.
2. Press and hold one of the MOVE GATE buttons to move the gate to
the open or close limit.
3. Press and release the SET CLOSE or SET OPEN button depending on
which limit is being set.
4. Press and hold one of the MOVE GATE button to move the gate to the
other limit.
5. Press and release the SET CLOSE or SET OPEN button depending on
which limit is being set.
6. Cycle the gate open and close. This automatically sets the force.
When limits are set properly the operator will automatically exit limit
setting mode.

ADJUSTMENT

• 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.
