    OPERATION MANUAL Level controller for conducting liquits WLS-GEH230V General dangers and precautions Instructions regarding documentation Please carefully read the following instructions before putting into operation! The symbols used in the operating manual are to make you careful, before hand, regarding safety considerations and dangers. But, in no way, these symbols can substitute the text of the associated safety instructions.

  • Page 4: Description

    OPERATION MANUAL Level controller for conducting liquits WLS-GEH230V Description Functional description The control device is used for regulating level of conducting liquids like supply line water, rain water or condensate. The measurement of level in the reservoir is done with the help of electrodes, for which either contact surface of the reservoir walls or self made rod type electrodes can be used.

    OPERATION MANUAL Level controller for conducting liquits WLS-GEH230V Operating sequence diagram Initial condition : The reservoir is first empty. The electrode E1 is not in water contact. Relay 1 is in closed position (because of this e.g. the inlet valve is open). The water level rises in the reservoir. Water contact with the lower Electrode E1 (1) does not change the relay status and only when Electrode E2 comes into water contact (2), Relay 1 switches OFF (as an effect e.g.

    OPERATION MANUAL Level controller for conducting liquits WLS-GEH230V Switching point adjustment The switching point is adjusted as per conductivity of water with the preset potentiometers. In normal practice, it is good enough to leave the potentiometer in the most sensitive position (left side limit).

    OPERATION MANUAL Level controller for conducting liquits WLS-GEH230V Connection of user‘s own sensors The following details are useful for persons with adequate knowledge of the associated electronics. The applicable safety regulations shall be duly followed! Connection and mounting operations shall be carried out only after switching off the voltage supply.

  • Page 10: Connection Of External Leds And Pushbuttons

    OPERATION MANUAL Level controller for conducting liquits WLS-GEH230V Electrodes of stainless steel rods, hanged from top into the medium, are ideally suited for this purpose. The reference electrode is in the middle of the 4 diagonally arranged sensing electrodes which are placed in a span of approx. 1-5 cm. The spacing should be wide enough so that no drop of liquid sticks back to the rods when the level falls down.
