Liquid Level Controller The Electro 11 pin plug-in range of control and timing devices are to be installed into a standard 11 pin base making installation easy and convenient. Level control unit of conductive liquids which can be configured for FILLING or EMPTYING. The unit can be used as a two probe system for alarm purposes or a three probe system to control HIGH and LOW levels of a reservoir. Up to four LV1 can be utilized in the same reservoir by connecting all commons (pin7). The sensitivity of the unit can also be adjusted. Features: Adjustable sensitivity Fail-safe control feature Low voltage probe signal Power supply ON and Relay ON LEDs Rear DIP switch selectable FILLING/EMPTYING Fail safe control and monitoring of high and / or low levels Modulated AC probe signal to prevent electrolytic corrosion DESCRIPTION Liquid conductive controller FUNCTION Emptying/ filling CONTACT 10A SPDT PROBE VOLTAGE 4 VAC PROBE CURRENT 2.5mA PROBE FREQUENCY 100Hz SENSITIVITY 4 – 50Ω RATED VOLTAGE 250V MECHANICAL LIFE 10×106 cycles PROTECTION INDEX IP IP 20 OPERATING TEMPERATURE -10 to + 50°C STORAGE TEMPERATURE -50 to + 85°C DIMENSIONS (MM) (H) 92 x (W) 36 x (D) 64
