A solenoid valve controller, comprising a plurality of solenoid valves intensively installed for controlling pressure fluid, a serial unit for performing on-off control of each of said solenoid valves according to a control signal from the controller, and a switch unit electrically connected between said solenoid valves and said serial unit, whereby:
said switch unit is equipped with a plurality of manual switches to match each of the solenoid valves,MULTI-FUNCTIONAL WATER PUMP CONTROL VALVE and said manual switches can be switched over to a switching position to connect the solenoid valves to output terminals of the serial unit and to a switching position to connect the solenoid valves to power terminals.Ball Valves It is an object of the present invention to provide a solenoid valve controller with simple arrangement, by which it is possible to easily check connecting and operating conditions of solenoid valves. To solve the above problems,Check Valves the solenoid valve controller according to the present invention comprises a plurality of solenoid valves intensively installed for controlling pressure fluid, a serial unit for performing on-off control of said plurality of solenoid valves according to a control signal from the controller, and a switch unit electrically connected between said solenoid valves and the serial unit, whereby said switch unit is equipped with a plurality of manual switches to match each of the solenoid valves, and said manual switches can be switched over to a switching position for connecting the solenoid valves to output terminals of the serial unit and to a switching position for connecting to power terminals. According to a preferred aspect of the present invention, the solenoid valves, the switch unit and the serial unit are intensively installed on a common mounting member. In order to confirm that each of the manual switches in the switch unit is in switching condition during operation, i.e. each of the manual switches is at a switching position for receiving the control signal from the controller, it is perferable that sub-switches are provided, which are turned on or off in response to manual operation of the manual switches and that the sub-switches are connected in series between detection terminals. Also, in another preferred embodiment of the present invention, the switch unit is removably provided, and the solenoid valves and the serial unit can be directly connected by removing the switch unit. In the solenoid valve controller with the above arrangement, it is possible to turn on the solenoid valve according to a serial signal from the controller by switching one of the manual switches to a switching position connected to the output terminals of the serial unit. Also, by switching to a switching position connected to the feeding terminals, the solenoid valve can be directly turned on through the power source. Therefore, it is possible to easily check connecting conditions or operating conditions of any solenoid valve as desired by switching over the manual switches on the switch unit without performing on-off control of the serial signals from the controller.
