Wiring & Assembly

1. Connect the Digital Board to the drive board using the multi-pin interface cable.
2. Connect the Heating Plate leads to the terminal block marked Heat.
3. Connect the AC Power Switch to the main input terminals: Live (L), Neutral (N), and attach the Earth Wire securely to the cleaning tank chassis.
4. Connect the Transducer positive terminal (+) to OUT+ and negative terminal (-) to OUT-.

Instructions for Wiring Between Circuit Board and Transducer

1. The circuit board cannot be powered on without load.
2. After installation, it is better not to start the machine for more than 1 minute without any cleaning fluid.
3. The 60W drive board is one transducer and is connected to the terminal of the circuit board. One circuit board and one transducer are used together.
4. The 120W drive board is two transducers and is connected to the terminal of the circuit board. One circuit board and two transducers are used together.
5. The 180W drive board is three transducers and is connected to the terminal of the circuit board. One circuit board and three transducers are used together.
6. OUT + is connected to the positive pole of the transducer, OUT – is connected to the negative pole of the transducer. The power supply L of the drive board is positive and N is negative. Parallel drive plate Lb is positive and Nb is negative. Heating PTC is positive and N is negative. The display board HT is the interface and the display board J1 is the temperature probe interface. Remember not to get it wrong.

(Note: The voltage at the output terminal of the circuit board is about 400V. Pay attention to safety. It is best to have a leakage protection switch on the input power supply to ensure safety!)

Multi-Transducer Parallel Connection

• Wiring Standard: 1.5 mm² wire.
• Connection Type: Ultrasonic transducers must be connected in parallel.
• Connect all transducer positive terminals (+) to generator OUT+.
• Connect all transducer negative terminals (-) to generator OUT-.

Transducer Stud Installation Instructions

• Stud Attachment Methods:
  • Sticker Stud: Welded to the stainless steel (SUS) plate using a capacitive discharge stud welding gun.
  • Backnail Stud: Welded to the SUS plate using manual arc welding.
• Installation Requirements:
  • Studs must be welded perpendicular (at a 90° angle) to the tank surface.
  • The bottom plate of the cleaning tank must remain completely flat without deformation, dents, or gaps.
  • Apply bonding agent evenly, thread the transducer tightly onto the stud, and ensure no gap exists between the radiating horn face and the tank bottom.
