3. Produktet er slutview
The Teekos JY4010 and JY4020 are double proportional valve amplifier boards designed to provide precise control signals for proportional hydraulic valves. These boards are crucial components in systems requiring accurate control of hydraulic pressure or flow, commonly found in injection molding and die casting machinery. They convert an input control signal into a modulated current output suitable for driving proportional solenoids.

4. Opsætning og installation
Installation should only be performed by qualified technicians. Refer to the machine's specific wiring diagrams and safety procedures before proceeding.
4.1. Montering
- Monter amplifier board securely within an electrical enclosure, away from excessive heat, vibration, and electromagnetic interference.
- Ensure adequate ventilation around the board to prevent overheating.
4.2. Ledningsforbindelser
The JY4010/JY4020 board features multiple terminal blocks for power input, signal input, and valve output. Specific pin assignments are typically silk-screened on the board or provided in a detailed wiring diagram from the machine manufacturer.
- Strømforsyning: Connect the appropriate DC power supply (e.g., 24V DC) to the designated power input terminals. Observe correct polarity.
- Signalindgang: Connect the control signal source (e.g., 0-10V, 4-20mA) from the machine's PLC or controller to the signal input terminals.
- Valve Output: Connect the proportional valve's solenoid coils to the corresponding output terminals on the amplifier board. Ensure correct wiring for each proportional channel (e.g., pressure and flow).
- Jording: Ensure all ground connections are properly made to the machine's protective earth.
4.3. Initial Adjustments
The board typically includes potentiometers for fine-tuning parameters such as minimum current, maximum current, ramp times, and gain. These adjustments should be made carefully according to the specific requirements of the hydraulic system and proportional valve being controlled.
- Minimum Current (Qmin/Pmin): Adjust to set the minimum current output to the valve, corresponding to the minimum desired pressure or flow.
- Maximum Current (Qmax/Pmax): Adjust to set the maximum current output to the valve, corresponding to the maximum desired pressure or flow.
- Ramp Tider: If available, adjust acceleration and deceleration ramp times to ensure smooth valve operation and prevent hydraulic shock.
- Gevinst: Juster forstærkningen, så den passer til amplifier's response to the input signal and the valve's characteristics.
Note: Always refer to the specific documentation of your proportional valve and hydraulic system for precise adjustment procedures.
5. Driftsprincipper
Once properly installed and adjusted, the amplifier board operates by receiving an analog control signal from a machine controller (e.g., PLC). This signal is then processed and converted into a precise current output that drives the proportional valve's solenoid. The current output is directly proportional to the input signal, allowing for continuous and fine control over the valve's opening, thereby regulating hydraulic pressure or flow.
- Input signal: The board accepts standard industrial control signals (e.g., 0-10V, 4-20mA).
- Udgangsstrøm: The output current drives the proportional valve, typically in the range of milliamps, precisely controlling the valve's position.
- Feedback (if applicable): Some advanced systems may incorporate feedback loops (e.g., from pressure transducers or flow meters) to the main controller, which then adjusts the input signal to the amplifier board for closed-loop control.
6. Vedligeholdelse
The Teekos proportional valve amplifier boards are designed for reliability and require minimal maintenance. However, periodic checks can help ensure optimal performance and longevity.
- Visuel inspektion: Periodically inspect the board for any signs of physical damage, loose connections, discoloration from overheating, or accumulation of dust and debris.
- Rensning: If necessary, gently clean the board using a soft brush or compressed air to remove dust. Ensure power is disconnected before cleaning. Do not use liquid cleaners unless specifically designed for electronics and applied with caution.
- Forbindelsesintegritet: Check all terminal block connections to ensure they are secure and free from corrosion.
- Miljøkontrol: Maintain the operating environment within specified limits regarding temperature and humidity to prevent premature component failure.
7. Fejlfinding
Before troubleshooting, ensure all safety precautions are followed and power is disconnected if physical inspection or wiring changes are required.
