Minilux Sensor PIR 41-271
Fitting and operating instructions
1. Application
The Minilux Sensor PIR 41-271 is used for movement
control.
Areas where movement control can be of benefit:
- Corridors
- Exhibition halls
- Office premises
- Conference premises
- School premises
- Production premises
- Canteens
- Sports halls
- Lounges
- Warehouses
- Caravans
2. Function
Sensor PIR 41-271 without built-in light sensor, is a
universal sensor for 12V DC supply and with a NPN
output.
3. Installation
Placement:
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, ceiling
mobiles and similar devices. This could result in
undesirable activation. Fig. 3.
To open the sensor, insert screwdriver into recess
and turn. Fig. 4.
In the case of outdoor installation, the sensor must
be fitted with a protective cap (type 41-902). Fig. 4.
Bear in mind that partitions, glass, plants, furniture
etc. will block the "beams". Fig. 5.
Fitting:
Fit the sensors on a wall with the bracket supplied or
directly in a corner. To bend the bracket, see Fig. 6.
Make sure the sensor is not turned upside down. Use
the dimensional sketch on the front cover as
reference.
Connection:
The sensor is connrcted according to fig. 7.
Parallel conection of sensors (max. 8), Fig. 8.
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. (power-up time).
It is easy to set the sensors by bending the bracket.
V indicates angle of bend and M range in metres.
Fig. 9.
For max. range the sensors should be fitted flat
against a wall (V=0°).
The lens takes account of the necessary inclination
to the ground.
If the printed circuit board has been disassembled,
the distance between the enclosure and PCB must
be 1 mm. Fig. 9.
Sensitivity can be set on the adjustment screw. Fig. 10.
The factory setting is for use under normal
conditions. If special circumstances mean that the
sensor is too sensitive or not sufficiently sensitive,
this can be optimised by correcting on the adjustment
screw.
The detection zones can be checked by using the
built-in walk test. Fig. 11.
Remember: Test only one sensor at a time.
In test pos. B, a light-emitting diode will light up
each time the sensor registers a movement.
After the walk test has been completed, remember
to return the jumper to pos. A
N.B. The lens must be fitted in a walk test.
5. 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 mixed with
ordinary detergent. Avoid pressing hard on the lens
on the front panel.
If the lens or other parts of the sensor are
defective, it/they must be replaced.
