PROBLEM

CAUSES

SOLUTIONS

Lighting stays on when there is no-one present

Sources of interference can cause false tripping, 

such as: air current, vibrations, radiators

1-  Reduce the sensitivity level

2-  If the interference continues: using the confi-

guration tool, go into the Detection system 

parameters, select Maintain and then choose 

PIR

3-  If the interference still continues, move the 

sensor away from sources of interference

Lighting does not switch off during the day 

when there is an adequate level of natural light

Regulation function not active

Light level threshold set too high

Light contribution is too high

Activate the regulation function

Reduce the light level threshold

Check that the sensor is positioned correctly in 

relation to the window

Decrease the power of the luminaires

Lighting switches off when there are people 

present and the natural light level is not ade-

quate (darkness)

Time delay too short

Detection sensitivity too low

Light level threshold too low

Increase the time delay

10 to 1 minutes is recommended for work areas

Increase the sensitivity

Move the sensor closer to the work area

Increase the threshold
