TO REMOVE THE TOP COVER
Note that a small black self-tapping screw is fitted under the small
facia cover of each photocell to secure the top moulding to the base.
Use a small flat blade screwdriver
to lever up the bottom of the
small black plastic screw cover.
Then use a small Pozi-Drive screwdriver to remove the screw
Assemble the wall bracket sections using the M5 screws and Flange nuts.
The reach of the main bracket may be adjusted dependant on which two sets of holes are
used to bolt the two parts together, as shown in the picture above left.
It is important to position the photocells with the infrared window uppermost and the body
protected from side impacts by the bracket side plate.
The Receiver photocell bracket should be fixed to the wall on the same side of the door on
which the door Control unit is mounted, to limit the wiring from the photocell to the
controller.
It is preferable to use a PVC insulated able with an outer diameter no greater than 5mm.
WIRING – PULSED SIGNAL SAFETY
If the Safety circuit of the door controller requires a two wire pulsed signal, then use a 2-
core cable and connect it from the two supply terminals on the Receiver to the SAFETY
terminals on the door controller, as described in the door controller manual.
The polarity of the cable is not polarity sensitive. It is essential that the door control safety
circuit voltage has a source resistance of 470 ohms with a 24V supply or 120 ohms with a
12V supply.
Set the PULSE MODE switch on the Receiver to
PULSE
.
If you are fitting the pre-wired photocell Receiver model 9044-PW, then the GREEN and
YELLOW wires are not required in PULSE mode.
