2.4.3 Installation of PH8PU1 Washer Pump and Water Tank
The PH8PU1 Washer Pump and Tank are used to provide water jet and brush cleaning in
drinking water applications. For details, refer to the separate IM 19C1E1-01E on PH8PU1
Washer Pump and Tank.
2.5 Wiring
This section describes the wiring between the ultrasonic oscillator and cleaner, and between
the solenoid valve, pump, and PH201G distributor. For the sensor wiring, refer to the chapter
describing the sensor.
2.5.1 Ultrasonic Oscillator Circuit Wiring
For the non-explosionproof ultrasonic oscillator, connect the cable from the cleaner directly to the
terminals inside the PUS400G Ultrasonic Oscillator.
For details of PUS400G, refer to the separate IM 19C1B3-01E.
For the explosionproof ultrasonic oscillator, connect the cable from the cleaner directly to the
terminals inside the PH8USF Ultrasonic Oscillator and PH8AL Alarm Box.
For detailsof PH8USF, PH8AL, refer to the separate IM 12B5U2-E.
2.5.2 Solenoid Valve Circuit Wiring
This is the wiring for the water jet or brush cleaning.
The wash timer in the Intelligent pH transmitter outputs a contact signal via the PH201G
Distributor. You should wire this contact to operate the solenoid valve. If you are using the
PH8PU1 Washer Pump and Tank, then the wiring is described in Sec. 2.5.3.
