Wiring Diagram
Wire Connections
Disconnect power before making or changing connections.
- Connect 220V AC phase to the red wire.
- Connect 220V AC neutral to the black wire.
- Connect the green wire to 220V AC phase whenever the valve needs to be open.
- The green-wire supply can be switched through a PLC, relay or float switch.
- Keep the green wire connected to phase for as long as the valve needs to remain open.
- Keep the red and black wires connected to phase and neutral during normal operation.
Power Failure and Consumption
The valve is a stay-put type on power failure: it remains in its last position when power is lost.
The supplied guide states that consumption is zero when closed and approximately 20mA when open. The main operating power is consumed while the valve is moving.
