PE Beam And Final Setup
13. Fitting the Photo Electric (PE) beam
sensor (optional)
Locate the PE Beam in a strategic location within
doorway. Automatic Technology recommends 150mm
above the fl oor level and as close as possible to the
door opening, inside the garage. Connect the wires
from the PE wiring harness as per Fig. 20.
NOTE: The wiring diagram is for an Automatic
Technology Transmitter/Receiver type PE beam: model:
PE-2 (Order Code 90214) with Wiring Harness (Order
Code 01900).
Make sure to align the beams correctly. Follow the
manual supplied with the Photo Electric Beam.
WARNING: The location of the beam and manner
in which it is installed might not give safety
protection at all times. Check to make sure
that the height of the beam and type used
give maximum protection possible.
External Secure Light Module (optional)
External secure light can be connected to GDO-8 Shed
Master ® as shown in Fig 21. The light stays on for
three minutes after the operation of the door. The built
in operate button can be used to open or close the
door.
14. Manual release
To switch the opener to manual mode simply pull the
red manual release handle down and release. To re-
engage the opener repeat the above action (Fig. 22).
Note: The door may move uncontrollably if the
spring tension is weak, not set properly or the door
is unbalanced. If this occurs, do not use the door and
contact your installer for service.
The manual release handle can be locked to prevent
unwanted disengagement (where fi tted). This is useful
if the opener is mounted on an exposed carport or
perimeter door. To disable the manual release, turn the
key clockwise to the locked position as indicated on the
label. To enable, turn the key anti-clockwise.
15. Reset all factory defaults
1. Turn power off.
2. Press and hold Set button.
3. Turn power on and continue holding Set until all
LED’s are off.
16. Re-initialising the opener
To re-initialise the opener press and hold the Set
Button for two (2) seconds. The beeper will sound
once. The door will start to move and re-calculate force
margins. The door can move between the open and
close limit positions up to four (4) times (depending on
the position of the door and the power up condition).
A single beep will be heard once the initialisation is
complete. The door is now ready for use.
