If all Sensors are non conducting then Relay is "OFF''. If Liquid level reaches "P1" Sensor then relay will be OFF (maintains previous state). When the level reaches "P2" Sensor then relay will be switched ON (As the liquid level has reached maximum level of Lower tank). Now Filling of Upper tank will start. When liquid level reaches "P3" Sensor, relay will be ON (maintains previous state). Now when liquid level reaches "P4" Sensor relay will be switched "OFF" (As *Liquid level has reached maximum level in the Upper tank). Now if Liquid level of upper tank is decreasing and it goes below "P4" Sensor, then the relay will be "OFF" (Maintains previous state), But when it falls below "P3" level, then relay will be switched "ON" until the liquid level is more than "P1" Sensor (i.e. until there is enough liquid in the upper tank). **Filling Control (Single Tank Monitoring with 3 Sensors)** **==> picture [163 x 54] intentionally omitted <==** **==> picture [79 x 155] intentionally omitted <==** **==> picture [135 x 64] intentionally omitted <==** When the level in the tank drops below the low level Sensor, the relay energises. The relay then remains energized until the level reaches the high level Sensor. As soon as the high level Sensor becomes submerged, the relay deenergizes and remains OFF until the level has dropped sufficiently below the low level Sensor. When "P3" & "P4" are non-conducting i.e. tank is empty, Relay is "ON". Whenever water level reaches "P3" Sensor, then again the relay will be ON (Maintains previous state of relay). But when water level touches the "P4" Sensor, then relay will be switched "OFF" (As Liquid reaches the maximum level). Again when water level decreases below "P4" level, then the relay will be switched "OFF"(Maintains previous state of relay). When water level reaches below "P3", then the relay will be switched "ON" (As the Liquid reaches minimum level) Newark.com/multicomp-pro Farnell.com/multicomp-pro sg.element14.com/b/multicomp-pro 30/03/23 V1.0 Page <3> ## **Liquid Level Controllers** ## **Filling Control (Single level Monitoring with two Sensors)** **==> picture [96 x 86] intentionally omitted <==** **==> picture [108 x 36] intentionally omitted <==** The output relay switches "ON" which starts up the relay when the Minimum level Sensor "P3" is no longer in contact with the liquid and switches "OFF" when the liquid reaches "P3". This operation is not recommended for pump controlling ## **Draining Control (Single Tank Monitoring with 3 Sensors)** **==> picture [84 x 134] intentionally omitted <==** **==> picture [174 x 128] intentionally omitted <==** When the level in the tank rises sufficiently to ubmerge the high level Sensor, the relay energizes. The relay then remains energized until the level has dropped below the low level Sensor. As the liquid drops below the low level Sensor, the relay deenergizes and remains off until the level has risen sufficiently to submerge the high level Sensor. When “P1” & “P2” are non-conducting i.e. when the tank is empty, relay is “OFF”. Whenever water level reaches “P1” Sensor, then again the relay will be “OFF” (maintains previous state of relay). But when water level touches the “P2” Sensor, then relay will be switched “ON” (as the Liquid reaches maximum level). Again, when water level decreases below “P2” level, then the relay will remain switched “ON” (maintains previous state of relay). When water level reaches below “P1”, then relay will be switched “OFF” (as the liquid reaches minimum level) ## **Draining Control** ## **(Single level Monitoring with two Sensors)** **==> picture [81 x 123] intentionally omitted <==** **==> picture [105 x 114] intentionally omitted <==** The output relay switches ON, when liquid level goes above a maximum level, fixed by the Sensor "P1", when the level drops below a "P1" Sensor, relay switches "OFF". This operation is not recommended for pump controlling.

It comprises of stainless steel Sensor with plastic holder and cable gland. A sealed ring and cable gland prevents liquid from entering the cable terminal connector and causing its oxidation. Maximum operating temperature : -10°C to + 65°CCable connection: Screw The external cable diameter must be 1.5 mm to warrant perfect sealing. ## **Part Number Table** |**Part Number Table**|| |---|---| |**Description**|**Part Number**| |Liquid Level Controller, 110V AC, 1CO, 1K to 200K Sensitivity|MP008412| |Liquid Level Controller, 240V AC, 1CO, 1K to 200K Sensitivity|MP008413| |Liquid Level Controller, 400V AC, 1CO, 1K to 200K Sensitivity|MP008414| |Accessories, Set Of 3 Stainless Steel Sensors|MP008415| **Important Notice :** This data sheet and its contents (the “Information”) belong to the members of the AVNET group of companies (the “Group”) or are licensed to it.
