6 APPLICATION Liquid alarm sensors are used in gas sample conditioning systems for monitoring gas cooling and condensate removal devices in order to provide protection for downstream analysis instruments. This monitoring device KS2 / KS2.Ex reliably signals the penetration of non conductive (e.g. alcohol) and conductive (e.g. water) liquid in the event of cooling or condensate removal equipment being defective, thus avoiding expensive down time as well as high repair costs for analysis instruments.

8 DESCRIPTION The M&C liquid sensor KS2 / KS2.Ex works on the principle of capacitive measurement and is suitable for non-conductive and conductive media. A pre-amplifier is integrated in the sensor housing and is connected with the necessary external electronic controller via 2- resp. 3-wire. For the sensor type KS2 the required electronic controller is available in various versions, FA1.1 or FA1.4 and is described in a separate data sheet. The M&C liquid sensor KS2.
9 FUNCTION 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.
9.3 CONNECTION OF THE SENSOR TYPE KS2.EX TO THE ELECTRONICS WE77/EX1 NOTE! The bridge between the connecting points 3 and 4 of the electronics WE77/Ex1 guarantees a „safty-first“ alarm release (alarm in case of voltage loss and parting of the cable).
9.5 ADJUSTMENT OF THE SENSOR TYPE KS2.EX Electronics WE77/Ex1 Sensor Left Right Bridge Poti Figure 4 Electronic KFA6-SR2-Ex1.W (left) and terminal box KS2.Ex respectively WE77/Ex1 Turn the potentiometer (figure 4) to the left until the LED is OFF. Turn the potentiometer slowly to the right. After the LED is ON, turn the potentiometer for another 1,5 rotations to the right. Sensor KS2.
