The TCS5JBL Low Voltage Top-up Switch is intended to ensure the availability of water in a tank by
topping up the tank when the level becomes low, with a measured amount of mains water.
Water level in the tank is sensed via a float switch, and top-up of mains water is achieved via a
solenoid valve connected to the mains water supply.
The solenoid will be activated when the float switch reaches a downward angle of approx 45deg or
more, the top-up cycle will then continue until the float switch reaches an upward angle of approx
45deg, thereby ensuring a measured quantity of water is introduced to the tank and avoiding
unnecessarily frequent top-ups.
The float switch and solenoid circuits are both powered by a safe low-voltage, either 24Vdc
(TCS5JBL) or 24Vac (TCS5JBLA) with limited current and over-voltage protection.
