Six sensors provided to be installed in water tanks. Three into overhead tank and three into underground tanks. Sensors placement should be as shown in this image. All three sensors into water tank is required for fully automatic operation.Motor will be turned on only if underground tank all three sensors into the water.Middle sensor "OL" in the overhead required to turn on the motor when water reaches below this sensor.Middle sensor "UL" required to stop the motor when water reaches below this sensor.Six numbers of sensors provided with this controller. This sensors are having best in quality sensing material and having 1.5 meter wire attached with it.1.0 square mm wire and below this size cables are accepted to be used for sensor installations. Small gauge wires can obtain more distance covered between sensor to controller. Higher gauge in wire can loss the signal between controller and sensor.Recommended wires for sensor installations are, Telephone cable, 0.5 square mm three core wire, internet cable or 0.25 square mm three core flexible wires.For power connections 2.5 square mm wires should be used.At some locations underground tank is not available so short C-UL-UH each other and underground tank sensors are bypassed. Then only three sensors need to be installed in overhead tank.To avoid dry running of motor we recommend to install underground tank sensors so whenever water is not present into the source tank, motor will not run.We advice please do not buy this controller if pump starter have red and green operative buttons and multi capacitors inside the starters.Only mcb type starters and having running capacitor starters can be used with this controllerOn site installation service and repairing not covered under this price. For warranty claim, customer must send controller back to our company by courier service. Make sure product is undamaged and warranty seals are not tempered.
