Section 4.2.3 shows how tilting and rotating the sensor can produce
different fields of coverage.

If the METER control is turned to – the coverage diameter is
substantially reduced.
We do not recommend the use of these units with ceiling heights
greater than 4.5m.

3.1.2 Helpful tips for installation
As the sensor responds to temperature change or moving heat sources,
please avoid the following conditions:

• Avoid highly reflective surfaces within the detection range.

• Avoid movable objects e.g. curtains and plants in the detection range

(these may cause erroneous detections when moved by air flow from
fans or air conditioner).

• Avoid heat sources (e.g. heating vents, radiators, air conditioners

and filament lamps) in detection range.

• Avoid fans drawing air across the sensor lens.

3.3 Installation procedure

3.3.1 To install the detector, cut a hole with diameter of 65mm in the
ceiling board and bring the power cable through the hole. Strip off
cable sheath and core insulation according to Fig. 6.

3.3.2 Unscrew protection covers on power box with a cross point
screwdriver. The RJ11 socket (use sensor A only) is for sensor connection
and screw terminals are for power and load(s). (See Fig. 7).

Instructions

2.1 Features

The PDFM362 PDFM361 controller is a ceiling flush mount
presence detector for indoor applications in commercial and
domestic locations. PDFM361 covers lighting applications only,
whereas PDFM362 can control lighting and HVAC
(heating, ventilating and air conditioning) applications.
Adjustment of Time and LUX value can be made either by the dial
controls on the sensor body or by the IR10 Infrared remote control.

• PDFM362 has two relays for outputs load I and load II:

load I is for lighting control and load II has voltage free contacts
for HVAC control which operate at all LUX (light) levels.

• Automatically adjusts to fit in a wide range of ceiling thicknesses.

• The sensor has a very high density of sensitive beams covering the

detection area. These are evenly distributed ensuring no dead spots
and detection of the smallest movements.

• RJ11 plug and socket for quick and easy connection.

• Built in LED in sensor giving confirmation of remote control settings

and easy test operation.

2.2 Dimension (see Fig. 1-A & Fig. 1-B)

Sensor: 80 dia. x 52mm

3.2 Wiring diagrams

3.2.1 PDFM362 controller (see Fig. 3).

Please disconnect power completely and read the
entire instruction manual carefully before installation.

PDFM362 – 6A breaker

A circuit breaker (250VAC,6A) type C according to EN60898-1
of load shall be installed in the fixed wiring for protection of load II.

PDFM361, PDFM362 – 10A breaker

A circuit breaker (250VAC,10A) type C according to EN60898-1
of load shall be installed in the fixed wiring for protection of load I.

This product must be
protected by a fuse or
circuit breaker with a
maximum rating of
10A or lower.

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).

Fig. 11-A (PDFM362 control dials)

Fig. 11-B (PDFM361 control dials)

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.
