The relay has an independent output for the indication of alarms in case the tank works dry or in case of an overflow state. Relay output SPDT/SPST 8A, NA/NC. Sensitivity control by potentiometer in 3 ranges., CLD4MA2D115, Connection cable PVC cable of 2,3,4 or 5 conductors, usually shielded. Cable length: max. 100 m. The resistance between the conductive wire and ground must be at least 500K. Normally, it is recommended to use a shielded cable between the probe and the relay, for example, if the cable is placed in parallel with the power (network) cables. The shielding has to be connected to Y5 (reference). Example 1 The diagram shows the level control connected as max. and min control, i.e. records of 2 levels + 2 alarm levels. The relays react to the low alternating current generated when the electrodes are in contact with the liquid. The reference (Ref) must be connected to the tank, or if the tank is made of a non-conductive material, to an additional electrode. (It will connect to the Y5 pin.) (In the diagram this electrode is indicated by a dotted line). Alarm outputs use Y4 electrodes for the High/High (HiHi) alarm, and Y1 for the Low/Low (LoLo) alarm outputs.
