Self test cycle 

After an initial 60-second self-test cycle (initialization), the 

LUXOMAT

®

 

PD4-M-3C-TRIO is ready for operation. 

Follow-up time for light control 3 (see point 7)

The time can be set infinitely variably at between 1 and 60 

minutes. The time-setting is valid for all 3 channels of the 

PD4-M-3C-TRIO.

TEST

: Test mode

 Every movement switches on the light for a period of 2 

seconds, switching it off for a period of 2 seconds after that  

regardless of the level of brightness.

Twilight-switch for light control (Channel 1) - potentiometer 

1 (see point 7)

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

and 1200 Lux. Using the rotary control, the luminance set 

points can be set as desired.

Installation and Operating Instruction for 

B.E.G.

-Occupancy detectors PD4-M-3C-TRIO-SM/-FC

A circular opening 

of diameter 100 mm 

must be produced in 

the ceiling.

Having connected 

up the cables in 

accor dance  with 

regulations, the 

detector is inserted 

into the opening as 

shown and fixed 

into position with 

the retaining bracket 

using screws.

7.  Position of potentiometer and DIP switch

The detector must be in stalled on a solid and  

level surface. The circular cover ring must be 

removed prior to assembly. To do this, twist the 

lens (C) anticlockwise by 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.

4.  Putting into operation of 

the remote control IR-PD4-

TRIO SWI (optional) 

Check Battery:

 

Open battery com-

partment by pressing 

the plastic springs to-

gether and removing 

the battery-holder. 

Caution:

 Settings with remote control su-

persede the settings by potentiometers.

5.  Light measuring

In order to calculate a switching 

threshold, there is a five-minute light 

measurement. For his the detector 

switches off all channels and turns 

them on for five minutes afterward.
This measurement is made if:
•  a new brightness value is changed 

with the potentiometer

•  a new nominal value is set by use of 

the remote control (finish setting up 

with CLOSE switch)

The measurement is not done during 

the activated test function.

Unlocking the device interrupts the 

light measuring.

 1. Mounting preparations 

 

Work on the 230 V mains supply 

may only be carried out by quali-

fied professionals or by instructed 

persons under the direction and 

supervision of qualified skilled elec-

trical personnel in accordance with 

electrotechnical regulations.

 

Disconnect supply before installing!

The device is not suited for safe 

disconnection of the mains supply. 

 

When in Master/Slave mode of 

operation, the Master-appliance  

must always be installed at the  

location where there is least  

daylight.
