9.1 CONNECTION AND ADJUSTMENT OF THE SENSOR TYPE KS2 AT THE
ELECTRONIC FA1.1

Link the sensor to the electronic FA1.1 (see also manual 5-6.10ME)
KS2 terminal X4/3 to FA1.1 terminal 15 (yellow)
KS2 terminal X4/2 to FA1.1 terminal 17 (white)
KS2 terminal X4/1 to FA1.1 terminal 18 (brown)
Adjustment with „dry“ sensor:

Turn the potentiometer to the left until the green LED is OFF and the red LED is ON.
Turn the potentiometer very slowly to the right. After the green LED is ON, turn the potentiometer
for another 0,5 rotations to the right.
Checking the sensibility:
Test the sensor with the condensate of your application, if possible. A condensate quantity of 1,5 ml
effects the alarm release. The sensor can be adjusted to a higher sensibility if the potentiometer is
turned to the left.
N O T E !
A sensor with high sensitivity can cause false alarms.
9.2 CONNECTION AND ADJUSTMENT OF THE SENSOR TYPE KS2 AT THE
ELECTRONIC FA1.4

Link the sensor to the electronic FA1.4 (see also manual 5-6.10ME)
KS2 terminal X1/3 to FA1.4 terminal 15 (yellow)
KS2 terminal X1/2 to FA1.4 terminal 17 (white)
KS2 terminal X1/1 to FA1.4 terminal 18 (brown)
