Force/Sensitivity Adjustment
Warning:
Improper Adjustment of Sensitivity System Force Could Cause Entrapment, Injury or
Death. Set Adjust For Just Enough Force To Operate The Door Reliably, But No Stronger. Do
Not Over-Adjust Force/Sensitivity System To Compensate For A Poorly Working, Sticking or
Binding Door (Contact a qualified Garage Door Service Person to Correct any binding, sticking
and/or other door problems).
Force/Sensitivity Adjustment
• Force/Sensitivity Adjustment Controls are located on the
Back Panel of the Opener (See Figure 15A). Up and Down
sensitivity adjustment are independent of one another (+
indicates more force) and ( indicates more sensitivity).
Never change the Force/Sensitivity setting by more than 1
increment at a time.
•
Note:
Force/Sensitivity is set at level 1 at the factory both
for the up and down adjustments. The size and operating
conditions of the garage door will determine the correct
level of Force/Sensitivity. Weather conditions may also
affect the operation of the door requiring further
adjustments as needed.
•
Note:
If the down pressure adjustment is set too light the
operator will reverse in the down cycle. If the up pressure
adjustment is set too light the operator will stop in the up
cycle.
•
Note:
There are 12 levels (increments) of up and down
force/sensitivity setting. When either the maximum or
minimum setting is reached the light will flash 6 times.
Setting Force/Sensitivity Adjustment
Down force/Sensitivity Adjustment
• In the down or close direction the operator will reverse if the
force required to close is exceeded. If the operator
completes a full closure without reversing decrease the
amount of pressure in increments of one push of the down
button until the operator reverses. Once the operator does
reverse in the down direction increase down pressure
by
pushing the down + button once.
Up Force/Sensitivity Adjustment
• In the up or open direction the operator will stop if the force
required to open the door is exceeded. If the operator
completes a full open cycle without stopping decrease the
amount of force in increments of one push of the up –
button until the operator stops during the up cycle. Once
the operator does stop increase the up force by pushing the
up + button once. For safety the force setting should always
be set at the least amount necessary to run the door
properly.
