This document describes the 20K ULTRASONIC GENERATOR (HC-CS2000C), an industrial-grade ultrasonic equipment designed for various applications, likely involving welding or similar processes that utilize ultrasonic vibrations. The manual emphasizes the importance of professional operation to prevent irreparable damage and provides detailed instructions for setup, operation, and troubleshooting.

Function Description

The HC-CS2000C is an ultrasonic generator that produces 20KHz ultrasonic vibrations. It is designed to be integrated into industrial processes, likely for tasks such as ultrasonic welding, cutting, or cleaning, where precise control over ultrasonic parameters is crucial. The device features a digital display for scanned frequency and various LEDs to indicate current operating modes (time or energy). It allows for adjustment of several key parameters, including delay time, welding time/energy, holding time, and amplitude, to suit different application requirements. The generator also incorporates fault protection mechanisms that display specific error codes and suggest solutions, ensuring operational safety and facilitating maintenance.

Important Technical Specifications

Power Supply Requirements:

Input Standard: Single phase AC220V 50HZ/60HZ.
Voltage Fluctuation Range: <10%.
Power Grid Harmonic Content: <20%.
Supply Current: <20A.
Power Cable Diameter: >2.5MM².

Environmental Requirements:

Operating Temperature: -20°C to 40°C. Exceeding this range can lead to work errors and fire.
Air Humidity: Less than 70%. High humidity can cause internal condensation, short-circuiting electronic components, and abnormal operation.
Electromagnetic Interference (EMI) Intensity: Less than 120E. Higher EMI can severely interfere with operation and damage the device. The manual notes that the ultrasonic power supply itself is a large source of electromagnetic radiation, recommending shielded and coaxial communication lines and energy output cables when multiple devices are installed tightly.

Interfaces:

Transducer Interface: Single-core high-voltage RF interface. The center line is the positive end of the transducer, and the shield is the negative end. Reversing this connection is strictly forbidden.
DB9 Female Interface: Uses conventional DB9 core wire connection, with an adapter board provided.
24V Power Supply Terminal: Provides a constant 24V, with a maximum current of 100mA.
Pressure Trigger Port: Valid when the device operates in pressure trigger mode.
Solenoid Valve Interface: Connects to a 24V solenoid valve with a maximum power of 5W.
Automatic Operation Start and Emergency Stop Wiring Port.
Power Socket: Character type interface.
Fuse Holder: Uses a 15A, 250V fuse.

Usage Features

Initial Setup:

All initial parameters are factory-set.
Requires professional operation due to high voltage and potential for damage.
Emphasizes safety warnings: do not operate with the housing open, avoid impact, use a grounded power supply, keep hands away from the welding horn, and do not operate without transducer and mold connected.
Before use, check for loose molds and ensure safety when replacing large molds. In case of abnormal conditions, resolve the fault before restarting to prevent further damage.

Operating Instructions (Initial Interface):

The digital display shows the scanned frequency.
Upper five LEDs are off; lower two LEDs indicate current time mode or energy mode.
A ship-type switch allows switching between automatic and manual mode adjustment.
A left LED light bar shows current power.
A right-side spring switch enables sound wave detection.
An upper right coding switch allows selection and adjustment of parameters.

Maintenance Features

Fault Protection Display and Solution: When the generator enters "Protection status," indicated by four lamps on and an alarm, the screen displays specific error codes to guide troubleshooting:

E-01: Power over loading.
- Solution: Reduce amplitude or loading (e.g., reduce pressure); replace with a larger ultrasonic generator.
E-02: Frequency out range.
- Solution: Cool the mold; check mold connection and transducer.
E-03: Frequency too low.
- Solution: Check mold connection.
E-04: Equipment operation fault.
- Solution: Check mold connection and transducer.
E-05: Parameters read failed.
- Solution: Close the equipment and reopen after one minute.
E-06: Loading error.
- Solution: Check the transducer, change it, or reconnect it.

The manual emphasizes the importance of following local laws and regulations when disposing of the device or replacing internal parts due to the large number of electronic components.
