Avanti DCU 400V

One Float Switch – 2 wire control

When the float contact is closed between terminals 5+7, the relay is energised.

On opening the float contacts the relay will de-energise.

Two Float Switch – 3 wire control:

For correct operation the Stop float must first close between terminals 6+7.

On this closure the Stop relay (STR) energises and makes contact between terminals 2+8.

The Start float is connected between 5+6 and on closure energises the ON relay.

This relay remains energised until the Stop float opens between 6+7.

The ON and STR relays are then both de-energised.

The STR relay is used for switching the electrical supply ON or OFF to the pump relay circuitry in the control panel.

Float terminal volts = 24V DC.

Distance: up to 4 km using 1.5mm copper wire/cable.
