PDFM362 PDFM361 can also be 
controlled by the infrared remote 
controller IR10. As well as allowing 
remote setting of times and light level 
the IR10 also enables continuous 
operation for 8 hours in ON or OFF 
modes as well as continuously in 
detection mode controlled by or 
independent of light level.
The IR10 is invaluable during 
commissioning enabling changes to 
be made without resorting to ladders.
Further to this the IR10 can download 
stored settings from one sensor to 
additional sensors in the same area.

3.3.2 (cont). The protection covers have teeth (see Fig. 8-A) giving 
a degree of cable clamping if power and load are connected by 
individual wires (0.8 –1.8mm dia.).
If connection is by cable (9 – 11mm dia.) then use of a coarse rat-tailed 
file to open out as many of the holes as necessary using the markings 
on the inside of the protection cover as an approximate guide 
(see Fig. 8-B).
Referring it to the appropriate wiring diagram insert the wires into the 
correct screw terminals and tighten fully. Then plug the sensor lead into 
SENSOR A socket only.
Use the coarse rat-tailed file to open a single hole (smaller than that 
above) in the remaining protection cover to take the sensor cable with 
a degree of strain relief. Secure down the protection covers.

3.3.3 Feed the wires/cables followed by the power unit through the 
65mm dia. ceiling hole (see Fig. 9).

4.1.1 TIME control adjustment
These are delay times between the sensor being triggered and the 
controller switching off assuming no further detections are made.
If there are additional detections the time delay applies from the 
latest detection.

PDFM362:

TIME 1: Adjustable from 5 sec. to 20 min. (lighting). (Extendable to 
30 min. and 60 min. when in use with the IR10 remote controller).
TIME 2: Adjustable from 10 sec. to 60 min. (HVAC).

PDFM361:

TIME: Adjustable from 5 sec. to 20 min. (lighting). (Extendable to 
30 min. and 60 min. when in use with the IR10 remote controller).
4.1.2 LUX control adjustment
The LUX level below which the sensor will operate is adjustable from 
10 LUX (operation only after dusk) to 2000 LUX (operation at any 
light level).
4.1.3 METER control adjustment
This control sets the diameter of detection coverage at floor level. 
Assuming a ceiling height of 2.5m at the + end of the scale the 
coverage diameter will be 7m, at the – end of the scale the coverage 
diameter will be 1m.
The affect of METER control at other ceiling heights is shown in section 3.1.

4.2 Test Mode

4.2.1 Sensor warm up
The detector will take a minimum of 60 seconds to warm up when the 
power is connected to it for the first time or if the power is being 
re-connected after being turned off.
During this period load I and the sensor LED will both be on. After the 
warm up is finished the sensor will revert to operation according to the 
settings of the controls on the sensor body.
4.2.2 LED function
There is a red LED (see Fig. 12) built into the sensor and visible through 
the PIR lens that shows the status of the loads and enables testing to be 
carried out without the loads 
being connected.
If the IR10 remote controller
is in use the LED will flash to 
give confirmation of the 
commands and adjustments 
made by the IR10.

3.3.4 Force the spring clips back until they can feed into the ceiling hole 
(see Fig. 10-A) and then push the sensor upwards into place so that its 
flange fits tightly against the ceiling (see Fig. 10-B).

4.1 Time, LUX and Meter Controls

Following marked values (excepting TEST and 

) are approximate, 

the values are continuously adjustable over the control range 
(see Fig. 11-A & Fig. 11-B).

4.2.3 Adjusting sensor head
The sensor head can be tilted by as much as 30º off axis as shown 
in Fig. 13A. This can be achieved by using a flat blade screwdriver 
as shown in Fig. 13B.
Fig. 13C shows the tilt angle markings on the sensor body. The tilt 
angle is read off against the edge of the mounting flange.
Fig. 13D shows the detection coverage for various tilt angles. 
The tilt angle can be used in conjunction with rotation of the 
sensor head within the flange up to 350º to give the required 
coverage in any direction. The markings on the sensor mounting 
flange (see Fig. 13E) giving 30º per division provide a useful 
way of adjusting angular position.

When the PDFM362 PDFM361 is not working as expected go 
through the troubleshooting guide below.

4.2.4 Walk test
Turn supply on and wait at least 60 seconds for the system to 
settle down.
Turn Time 1 control to the Test position. This means that the sensor 
LED and load I will turn on for 2 seconds after triggering and then 
be off for 3 seconds after which the sensor can be re-triggered. 
The triggering is independent of light level.
The installer should move around in the detection area to establish 
that it is all covered. If necessary the tilt and rotation of the sensor 
should be adjusted, after which the area should be walk tested 
again to confirm coverage is as required.
To confirm that load 2 (HVAC) is operating correctly for a 
PDFM362, carry out the following:- 
Turn LUX (light level) to its minimum value (10 lux) to stop 
load 1 (lights) from turning on. Then turn TIME 2 (HVAC) to 
minimum value (10s) and carry out a limited walk test to 
confirm correct operation of load 2.
