< 3. Installation, Piping and Wiring > 3.3.3 Wiring Normally, washing is executed when a "cleaning" contact signal is received from the converter. Note: The contact output must be set to "cleaning" function. For details, refer to the user’s manual supplied with each converter. Install wiring so that when the contact signal is output drive power is supplied to the solenoid valve (or pump), and utility (air or water flows into the washing device). - Page 26 Blank Page...
