ADJUSTMENT

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.
• 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.
