CONTACT REVERSE TEST
The force adjustments and limit switch settings
MUST BE COMPLETED before testing.
1. Testing.
• Open garage door using Wall Button.
– Place a 2" x 4" board (laid flat) under center
of garage door opening (Fig. 6-6).
• Close door using Wall Button.
• When door contacts board, it must stop and
reverse (within 2 seconds) to open position.
2. Adjustment.
• If the door does not properly reverse.
– Check to see if door has "close" limit
programmed. It should not have reached its
"close" limit before hitting board.

decrease "CLOSE FORCE" control
setting slightly (turn it counter-clockwise).
• Test again. Repeat as necessary until door
reverses upon contacting board.

the DOWN force can be increased. By turning
the Down Force Control counter-clockwise,

UP force can be increased. By turning the Up Force
Control counter-clockwise, the UP force can be
decreased. Set the UP force level at the minimum
force required to open door without stopping.
