    Hey Guys
    Some of you asked me for a wiring diagram for a "auto top up RO system'.
    I will post it here for everybody to use.

    This diagram includes two float switches which the bottom one will be used to start/ open the pump/solenoid.
    The second float switch will be used to close/stop the pump/solenoid.
    Only use 12 volt when connecting float switches

    11 pin relay was used in this diagram but a 8 pin will also work.
    only two C/O (common operation) will be used.

    Float switch 1 is connected in N/C (Normally Close)
    Float switch 2 is connected in N/O (Normally open)

    Operation is as follows...
    Water level will get empty, float switch 2 will close and pump/solenoid will start/open.

    Drum will fill up water until float switch 1 is open and pump/solenoid will stop/close.

    Enjoy and be safe.

    Voltex, acdc dynamics, any electrical supplier would be able to help you with stock or placing orders.
