Testing The Automatic Reversal System - Ryobi GD125 Operator's Manual

WARNING:
If you are not able to first set the travel limit for the open
position, do not skip ahead and attempt to set the travel
limit for the closed position. If the travel limits do not set
and the door does not move in the intended direction as
described in this section of the Operator's Manual, do not
use the garage door opener and contact customer service
or a qualified service person for assistance. The use of a
garage door opener that is not operating the garage door
in the correct direction can kill or seriously injure someone
in the moving door's path.
To set the travel limit for the closed position:
 Press and hold the DOWN button for three seconds. After
you release the button, it will begin blinking and continue
blinking until the travel limit has been set.
 Press and hold the DOWN button to move the garage
door to the closed position.
 For fine adjustments, press and release the UP or DOWN
buttons.
 Once the door is in the desired closed position, press
the SET (
) button to program the travel limit. Once the
travel limit is set, the DOWN button will stop blinking and
shine continuously.
NOTE: If the safety sensors are obstructed during this
process, travel limit information for the open and closed
position will be erased.
To test the travel limits:
NOTE: The garage door opener will not respond to the
remotes or keypads until the travel limits have been tested.
 Press and release the UP button and ensure that the door
moves to the programmed open position. The button will
blink as the door moves, then shine continuously once
the door is in the open position.
 Press and release the DOWN button to ensure that
the door moves to the programmed down position.
The button will blink as the door moves, then shine
continuously once the door is in the down position.
NOTE: After testing is complete, the light for both the UP
and DOWN buttons will turn off.
 If the travel limits were set incorrectly, they can be cleared
by pressing and holding the UP button for three seconds.
If a buzzer sounds while you are setting or testing the travel
limits, the garage door opener has detected a problem.
Travel limit information for the open and closed position
will be erased and cannot be reset until the problem is
resolved. For details, refer to the Troubleshooting section
later in the manual.
INSTALLATION
TESTING THE AUTOMATIC REVERSAL
SYSTEM
See Figure 72.
Test the automatic reversal system after installation, prior
to first use, every month, and after any adjustments are
made to the garage door travel limits. If the door contacts
an object higher than 1-1/2 in. off the garage floor (approx.
the size of a 2x4 laid flat), it should stop and reverse to
the fully open position. If the automatic reversal system
does not function properly, a closing garage door could
kill or seriously injure someone in its path.
