CLP2FA1B115, Conductive Sensors 2-Point Level Controller, Model CL Cascade Connection with Potentiometer, CLP2FA1B115, Level Control Relay for Conductive Liquids That Can Control Two Levels of Filling or Emptying. The relay is characterized by a sensitivity range of 250Ω to 500kΩ corresponding to 4m siemens to 2μ siemens. If more than two levels are needed, more systems can be added., CLP2FA1B115, Connection cable PVC cable 2 or 3 conductors, usually shielded. Cable length: max. 100 m. The resistance between the common and the common wire 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 pin 7 (reference). Waterfall If more than 2 levels are needed, up to 7 amplifiers can be cascaded, as shown in the following example. Connect pin 11 of the master relay to the common and pin 9 of the master relay to pin 8 of the next relay, the slave relays (see drawing). Pin 11 of the slave relay must be left unconnected. Pin 9 of the first slave must be connected to pin 8 of the second. Pin 9 of the last slave must be connected to pin 8 of the master. Connections must be made with shielded cable to achieve optimal operation, if the cables go by tray next to power cables. Connect the shielding to pin 7 and make sure that the distance between the two systems is a maximum of 3 m. Adjust the sensitivity of the connected system and the systems are ready to go.
