 PD4-DIM/-DUO-

DIM is ready for operation. 

Follow-up time for light control

 The time can be set infinitely variably at between  

1 and 30 minutes. The time-setting is valid for both DIM-Out-

puts of the PD4-DUO-DIM.

: Test mode (Every movement switches on the 

light for a period of 1 second, switching it off for a period of 

2 seconds after that regardless of the level of brightness)

Twilight-switch for light control (relay 1)

The switch-on value for the light can be set at between 40 

and 2000 Lux. Using the rotary control, the luminance set

This rotary controller serves to determine the working time of 

the orientation lighting (fixed to 20 %).

Installation and Operating Instruction for B.E.G. - Occupancy detectors PD4-M-DIM and PD4-M-DUO-DIM

A circular opening of diameter 68 – 70 mm 

must be produced in the ceiling. Having 

connected up the cables in accordance 

with regulations, the detector is inserted 

into the opening as shown in the drawing 

opposite and fixed into position with the 

assistance of the spring clips.

The detector can be installed in 

conventional inlet-sockets mounted on 

the ceiling. 

The assembly plate enclosed must be 

stripped off prior to installation and 

secured to the ceiling using 4 screws 

and ensuring that it flat. Having con-

nected up the cables in accordance 

with regulations, the detector can be 

placed in position as shown in the 

drawing opposite and, applying a 

little pressure, can then be locked into 

position with the assistance of the 

spring clips.

(Please refer to the connection 

diagrams)

The detector must be installed on a solid and  

level surface. The circular cover ring must be 

removed prior to assembly. To do this, twist the 

lens (C) anticlockwise through approximately 5° 

and lift off. 

Having connected up the wires in accordance with 

regulations, secure the detector with 2 screws.  

After installation replace the lens and lock (turn 

clockwise). Mains to be connected

1.Mountingpreparations

Work on the 230 V mains supply 

may only be carried out by qualified 

professionals or by instructed persons 

under the direction and supervision 

of qualified skilled electrical person-

nel in accordance with electrotechni-

cal regulations.

 

Disconnect supply before installing! 

 

When in Master/Slave mode of 

operation, the Master-appliance  

must always be installed at the  

location where there is least  

daylight.

Luminance set point for constant light regulation 

Dimming 

The following approach will prove useful when setting a 

command value (example workplace): Place a luxmeter flat 

on the desk, then, using the remote control IR-PDim, adjust 

the light up or down by pressing the keys max or min until 

the desired command value which best suits your require-

ments has been reached.

Automatic reading in the current light value  

as new luminance set point

Grey button:

  Programming the switch-off delay time

On button:

    Orientation light is permanently activated.

Note:

 During the orientation light phase, the constant light  

regulation is also active: if there is sufficient brightness,  

dimming occurs < 2 V and, if applicable, the lighting is 

switched off.

Fully automatic/semi automatic mode => (see page 2, point 5) 

Semi automatic: green LED,  

Fully automatic: red LED on for ca. 3 sec.

Resetting when open

All values which have been programmed using the remote 

control IR-PDim are deleted, and those values which have 

been set by potentiometer are activated.

Test mode 

Reset to deactivate

Resetting when closed

The lighting relay is switched off, i.e.  

opened and the follow-up times reset.

Permanent protection against sabotage

This function blocks the unit permanently (green LED is illuminated). 

This operating mode can only be activated during the period of 5 

seconds after pressing the “lock“ button. This status will only  

permit actuating the function “Light on/Light off”.
The procedure for leaving this mode is as follows:

 

1. Switch off the current 

 

2. Apply current for 31 - 59 seconds  

 

3. Switch of the current again 

 

4. Apply current 

 

5. Open detector

Light on/off

The light will remain switched on/off for as long as movements  

are detected in the areas of coverage. Once the last movement  

has been detected, the light will remain on for the duration of the 

follow-up time as per setting.  

The appliance will then return independently to the mode selected 

(Fully or Semi-automatic).

PD4-DUO-

DIM-FMwithsocketforSurfaceMounting

Before mounting the base, the 

enclosed mounting plate must 

be mounted true to side, i.e. 

the writing must be legible. 

Now fix the base on ceiling 

or wall, but first put the cable 

through one of the cable 

openings provided. 

The detector must be mounted 

on a flat, solid surface. 

Next prepare the sensor part by screwing in 

both fixing screws according, then connect the 

cable. Now insert the sensor part. Press beyond 

the spring housing pressure so that the sensor 

part firmly locks in place.
