คู่มือการใช้งานเครื่องควบคุมแรงดันอิเล็กทรอนิกส์ PEDROLLO Presscontrol Easy Press II

1. สินค้าหมดview

The PEDROLLO Presscontrol Easy Press II is an advanced electronic device designed to automate the operation of single-phase electric pumps up to 2 HP. It manages the pump's start and stop functions based on water demand, activating the pump when a tap is opened and deactivating it when the tap is closed.

Equipped with microprocessor logic, the Easy Press II offers crucial protection features. It safeguards the pump against dry running, automatically or manually resetting the system after a dry-run event. Furthermore, it prevents excessively frequent pump starts, which can occur due to minor leaks in the water system, thereby extending the pump's lifespan and ensuring stable water pressure.

4. ข้อมูลด้านความปลอดภัย

Always read and understand all safety warnings and instructions before installing, operating, or maintaining the PEDROLLO Presscontrol Easy Press II. Failure to follow these instructions could result in electric shock, fire, serious injury, or property damage.

• Ensure the power supply matches the device's specifications (230V, 50/60Hz).
• All electrical connections must be performed by a qualified electrician and comply with local electrical codes.
• โปรดถอดปลั๊กไฟก่อนทำการติดตั้ง บำรุงรักษา หรือแก้ไขปัญหาใดๆ
• Do not operate the device if it is damaged or if the power cable is frayed.
• เก็บเด็กและบุคลากรที่ไม่ได้รับอนุญาตให้ห่างจากพื้นที่ติดตั้ง
• ตรวจสอบให้แน่ใจว่ามีสายดินที่เหมาะสมเพื่อป้องกันอันตรายจากไฟฟ้า

5. การติดตั้งและการตั้งค่า

The Easy Press II is designed for easy integration into single-phase electric pump systems. Proper installation is crucial for optimal performance and safety.

1. การติดตั้ง: Install the Easy Press II vertically, ensuring the flow direction matches the arrows on the device. It should be mounted between the pump and the first point of water consumption.
2. การเชื่อมต่อไฮดรอลิก: Connect the inlet of the Easy Press II to the pump's discharge and the outlet to the system's piping. Ensure all connections are watertight using appropriate sealants (e.g., PTFE tape).
3. การเชื่อมต่อไฟฟ้า:
   • Connect the power supply cable to the Easy Press II's input terminals.
   • Connect the pump's power cable to the Easy Press II's output terminals.
   • Ensure all connections are secure and properly insulated. Refer to the wiring diagram provided in the technical documentation (Figure 2).
4. การเตรียมระบบให้พร้อมใช้งาน: Before starting the pump, ensure the pump and the Easy Press II are fully primed with water to prevent dry running.
5. การเริ่มต้นใช้งานครั้งแรก: Once all connections are secure and the system is primed, restore power. The Easy Press II will initiate the pump when water demand is detected.

6. การดำเนินการ

The PEDROLLO Easy Press II operates automatically once installed and powered. It functions as an electronic flow and pressure switch.

• Pump Start: When a tap or valve in the system is opened, causing a drop in pressure and flow, the Easy Press II detects this demand and automatically starts the connected electric pump.
• Pump Stop: When all taps or valves are closed, and water flow ceases, the Easy Press II detects the absence of flow and stops the pump after a short delay, maintaining system pressure.
• ตัวบ่งชี้สถานะ: The device features LED indicators (Power, Out of Service, Dry, Running, Frequent Start-up) to provide visual feedback on its operational status. Refer to the device's front panel for specific indicator meanings.

7. การบำรุงรักษา

The PEDROLLO Easy Press II is designed for minimal maintenance. However, regular checks can help ensure its longevity and reliable operation.

• การตรวจสอบปกติ: Periodically check the device and its connections for any signs of leaks, damage, or corrosion.
• ความสะอาด : Keep the exterior of the device clean and free from dust or debris. Do not use abrasive cleaners.
• ฤดูหนาว (ถ้ามี): In areas subject to freezing temperatures, ensure the device and connected piping are drained or protected from frost to prevent damage.
• Pressure Gauge Check: Monitor the pressure gauge regularly to ensure it is functioning correctly and providing accurate readings.

Always disconnect power to the device before performing any maintenance or inspection.

8 การแก้ไขปัญหา

The Easy Press II incorporates intelligent features to protect the pump and indicate operational issues. Here are common scenarios and their resolutions:

• Pump Not Starting / "Dry" Indicator On:
  • สาเหตุ: Dry running detected (no water in the pump or suction line).
  • สารละลาย: Ensure the pump is primed with water. The Easy Press II may attempt an automatic reset after a period. If not, manually reset the device by pressing the "START/STOP" button or by cycling the power.
• Pump Cycling Frequently / "Frequent Start-up" Indicator On:
  • สาเหตุ: Small leaks in the system (e.g., dripping tap, faulty toilet fill valve) or a non-return valve issue.
  • สารละลาย: Inspect all plumbing fixtures and connections for leaks. Repair any leaks found. Check the non-return valve in the system for proper operation.
• Pump Not Stopping:
  • สาเหตุ: Continuous water flow (e.g., open tap, major leak) or a sensor malfunction.
  • สารละลาย: Close all taps and check for significant leaks. If the pump continues to run without demand, disconnect power and contact a qualified technician.
• No Power / "Power" Indicator Off:
  • สาเหตุ: No electrical supply to the device.
  • สารละลาย: Check the circuit breaker, fuses, and power connections. Ensure the power outlet is functional.

For issues not covered here, or if troubleshooting steps do not resolve the problem, contact a qualified technician or the manufacturer's support.
