Light reference setting

1. Set the lighting level as close to normal work conditions as possible.

2. Turn the “Light Ref. Level Adj.” potentiometer until the “Light” LED is lit or 

goes out.

3. Turn the potentiometer one scale mark interval to the right.
4. Should the “Light” LED remain dark, even though the potentiometer is in the 

Min. position, the potentiometer can either be left in this position or turned one 
scale mark interval to the right, depending on the sensitivity level desired.

5. Turn the key switch “Trip Condition” of one REA 101 relay into position 

/LJKW

6. Expose one sensor fibre at a time to light, for example using a flash, and check 

that the right circuit breakers operate. 

7. When all of the sensor fibres have been tested, set the Trip Condition key 

switch/key switches as required by the application.

The Trip Condition key switch must always be in an extreme position.
