Activate the opener with any of the following:
The Remote Control Transmitter. Hold push
button down until the door starts to move.
The Door Control. Hold push bar down until the
door starts to move.
The Outside Keylock or Keyless Entry.
(See Accessories.)
When the opener is activated with the Safety
Reversing Sensor installed and correctly aligned:
1. If open, the door will close. If closed, it will open.
2. If closing, the door will reverse.
3. If opening, the door will stop (allowing space for
entry and exit of pets and for fresh air).
4. If the door has been stopped in a partially open
position, it will close.
5. If obstructed while closing, the door will reverse.
6. If obstructed while opening, the door will stop.
7. The garage door will reverse in the closing cycle,
and the opener light will blink for 5 seconds, when
the invisible beam is broken. If fully open, the door
will not close when the beam is broken. The sensor
has no effect in the opening cycle.
If the sensor is not installed, or is not aligned correctly,
the door won't close from any remote control
transmitter. However, you can close the door with the
Door Control, the Outside Keylock, or Keyless Entry, if
you activate them
until down travel is complete.
If you
release them too soon, the door will
reverse.
The Opener Light will turn on under the following
conditions: When the opener is initially plugged in;
when the power is interrupted; when the opener is
activated. It will turn off automatically after 4-1/2
minutes or provide constant light when the Light
feature on the Multi-Function Door Control is
activated. Bulb size is 75 watts maximum.
SECURITYmodels: Light will also turn on when
someone walks through the open garage door.
The lockout feature
prevents the trolley from
reconnecting auto-
matically. Pull the red
manual release handle
down and back (toward
the opener). The door
can then be raised and
lowered manually as
often as necessary. To
disengage the Lockout
Feature, pull the manual
handle straight down.
The trolley will reconnect
on the next UP or DOWN
operation.
