System Wiring Instructions

1. Connect the multi-pin ribbon cable between HEADER 5 on the driver board and the digital control panel.
2. Connect the switched AC inlet to the board’s power input terminals: Live (L) and Neutral (N). Connect the green/yellow grounding wire to the stainless steel chassis.
3. Connect the heating element leads to the terminal block marked Heat.
4. Connect the two ultrasonic transducers in parallel: connect both transducer positive terminals (+) to OUT+, and both negative terminals (-) to OUT-.

• Wiring Gauge: Transducer connections must use 1.5 mm² wire.
• Transducer Polarity: All transducers must be connected in parallel. Never connect transducers in series.

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 (Live) and N is negative (Neutral). 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!)

Transducer Installation & Stud Welding Instructions

• Mounting Stud Options:
  • Sticker Stud: Welded to the stainless steel (SUS) plate with a stud welding gun.
  • Backnail Stud: Welded to the SUS plate via arc welding.
• Mounting Procedures:
  1. Ensure the welding stud is perpendicular to the base plate. Tilted studs prevent uniform surface contact.
  2. The tank plate must remain completely flat without indentation or deformation at the weld joint.
  3. Apply specialized adhesive evenly over the contact base, then screw the transducer tightly down to the tank bottom.
  4. Ensure zero gap or interval exists between the radiating horn face and the cleaning tank surface.
