CONTROLS CONTROLS EN SERIES LIQUID LEVEL CONTROL UL listed * * * * CSA recognized Pump Up or Down Control DIN-Rail Enclosure 5 k to 100 k SPDT 8 Amp Relay Output GENERAL FEATURES: FILLING OR EMPTYING CONTROL (EN): The EN series is designed to monitor conductive liquids such as tap water, waste water, sea water, coffee, etc. The principle is based on the measurement of the resistance of the liquid between two submerged probes. When this value is lower than the preset threshold selected on the dial of the unit, the output relay changes state. Applications are found in the environmental and chemical industries, food equipment machinery and food processing technology.

It returns to its initial state when the minimum probe is no longer in contact with the liquid. Regulation of one level: Connect the maximum and common terminals together. The relay will change state when the minimum probe enters or leaves the liquid. Note: If the power break T lasts for 0.5 seconds or more, the relay reenergizes instantly if in UP mode and is deenergised if in DOWN mode.
