FORCE SETTING AND FINE ADJUSTMENT

SET THE FORCE
With entrapment protection attached, cycle the door open and
closed using the green "TEST BUTTONS". The operator will
automatically set the force.
FINE TUNE THE FORCE
The REVERSAL FORCE DIAL on the control board is used for fine
tuning the force in cases where wind or environmental changes
may affect the door travel.
Based on the length and weight of the door it may be necessary to
make additional force adjustments. The force setting should be
high enough that the door will not cause nuisance reversals, but
low enough to prevent damage to door or property. The force
setting is the same for both the open and close directions.
1. Open and close the door with the TEST BUTTONS.
2. If the door stops or reverses before reaching the fully open or
closed position, increase the force by turning the force control
slightly clockwise.
3. Perform the “Obstruction Test” after every force setting
adjustment (see below).
OBSTRUCTION TEST
The operator is equipped with an automatic obstruction sensing
feature.
If the door encounters an obstruction during motion, the operator
will automatically reverse or stop the door. After any adjustments
are made, test the operator:
1. Open and close the door with the TEST BUTTONS, ensuring
that the door is stopping at the proper open and close limit
positions.
2. Place a solid object under the open door. Ensure that the
door, and the solid object can withstand the forces generated
during this obstruction test.
3. Run the door in the close direction. The door should stop and
reverse upon contact with the solid object. If the door does
not reverse off the solid object, reduce the force setting by
turning the force control slightly counter-clockwise. The door
should have enough force to reach both the open and close
limits, but MUST reverse after contact with a solid object.
SETTING TIMER-TO-CLOSE
The TIMER-TO-CLOSE (TTC) dial can be set to automatically close
the door after a specified time period.
The TTC is factory set to OFF. If the TTC is set to the OFF position,
then the door will remain open until the operator receives another
command from a control. Rotate the TIMER-TO-CLOSE dial to the
desired setting. The range is 0 to 180 seconds, 0 seconds is OFF.
NOTE: Any radio command, single button control, or CLOSE
command on the control board prior to the TTC expiring will close
the door. The TTC is reset by any signals from the open controls,
loops, safety edges, and close photoelectric sensors (IR’s).
