Installation should only be performed by qualified technicians. Refer to the machine's specific wiring diagrams and safety procedures before proceeding.

4.1 మౌంటు

• మౌంట్ ది 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. వైరింగ్ కనెక్షన్లు

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.

• విద్యుత్ సరఫరా: Connect the appropriate DC power supply (e.g., 24V DC) to the designated power input terminals. Observe correct polarity.
• సిగ్నల్ ఇన్పుట్: 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).
• గ్రౌండింగ్: Ensure all ground connections are properly made to the machine's protective earth.

4.3. ప్రారంభ సర్దుబాట్లు

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 సమయాలు: If available, adjust acceleration and deceleration ramp times to ensure smooth valve operation and prevent hydraulic shock.
• లాభం: Adjust the gain to match the amplifier's response to the input signal and the valve's characteristics.

గమనిక: Always refer to the specific documentation of your proportional valve and hydraulic system for precise adjustment procedures.

5. ఆపరేటింగ్ సూత్రాలు

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.

• ఇన్పుట్ సిగ్నల్: The board accepts standard industrial control signals (e.g., 0-10V, 4-20mA).
• అవుట్‌పుట్ కరెంట్: 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. నిర్వహణ

The Teekos proportional valve amplifier boards are designed for reliability and require minimal maintenance. However, periodic checks can help ensure optimal performance and longevity.
