Tray switch prevents a pump or valve from turning on until the register counter has been reset. Also used for resetting external digital displays after a transaction is finalized.
The Interlock Tray Swith with associated circuitry prevents a pump or valve from turning on until the reset operation is complete, and it protects the meter register from clutch damage caused by improper resetting during product transfer. Also used for resetting external digital displays to zero after a transaction is finalized, when used with the optional pulse transmitter.
The specially designed reset switch and cam assembly causes the switch contact to change whenever an operator attempts to reset the register. Only after a proper reset is complete, can the system be activated again and the delivery be resumed.
