Minilux PIR 41-270 Sensor
Fitting and operating instructions
1. Application
The Minilux PIR 41-270 Sensor is used in connection
with the Minilux Control/Luxstat Control for lighting
control.
Areas where lighting control can be of benefit:
- Corridors
- Office premises
- Canteens
- Lounges
- Toilets
2. Function
The PIR 41-270 Sensor does not have an in-built
light sensor
Depending on which kind of Controller is connected,
the Minilux PIR 41-270 Sensor turns on the light in
the room. The light is turned off automatically after a
preset period, when the PIR 41-270 Sensor does not
detect activity in the coverage area.
3. Installation
Location:
The sensors respond to heat and movement in
relation to the surroundings.
The sensors are most sensitive when movements
(direction of walking) take place diagonally or across
the “beams”. Figs. 1 and 2
Avoid locating close to “heat sources”: cookers,
electric radiators, ventilation systems, mobiles, etc.
These can cause unwanted activation. Fig. 4
To open the sensor: Insert screwdriver into recess
and turn. Fig. 7G.
Fitting:
The sensors are designed to be fitted in a Euroformat
box. Figs. 7A-7F
Connection:
Example of connection, Fig. 3.
Parallel connection of sensors (max. 8), Fig. 3a.
Max. length of cable to Minilux Control: 200 m with
2 x 2 x 0.6 mm.
4. Settings
After connection to the power supply, PIR Sensors
are ready for operation after 1-2 min. (warm-up time).
The range at 90° and 40° respectively is shown in
Figs. 5 and 6
5. Troubleshooting
6. Maintenance
Dirt affects the operation of the sensor and the
sensor’s lens must therefore be kept clean. Use a
damp cloth for cleaning. Use water with a standard
detergent. Avoid pressing hard on the lens in the
front.
If the lens or other parts of the sensor are defective,
the sensor must be replaced.

Problem:
PIR 41-270 Sensor fails to switch on
1. Incorrect connection
1. Check that the sensor is connected as shown in
Fig. 3
2. The sensor does not receive any power supply
(24V on terminals 1 and 2)
2. Check that the Controller is connected correctly.
3. Lux level on the Controller is incorrect.
3. Check that the Controller is set correctly.
No/poor detection in walk test
1. Incorrect location.
1. Position the sensor as shown in Figs. 1, 2, 5 and
6
2. The lens is covered/dirty or defective
2. Remove the cover/clean the sensor as described
in item 6. If the lens is defective, the sensor must
be replaced.
