PDFM362 / PDFM361 can also be
controlled by the infrared remote
controller IR-10. As well as allowing
remote setting of times and light level
the IR-10 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 IR-10 is invaluable during
commissioning enabling changes to
be made without resorting to ladders.
Further to this the IR-10 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 5sec to 20min (lighting). (Extendable to 30min
and 60min when in use with the IR-10 remote controller).
TIME 2: Adjustable from 10sec to 60min (HVAC).
PDFM361:
TIME: Adjustable from 5sec to 20min (lighting). (Extendable to 30min
and 60min when in use with the IR-10 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 visable 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 IR-10 remote controller
is in use the LED will flash to
give confirmation of the
commands and adjustments
made by the IR-10.
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.
