პროდუქტის დაზიანების ან დაზიანების თავიდან ასაცილებლად, ყოველთვის დაიცავით შემდეგი უსაფრთხოების ინსტრუქციები:

• Ensure all power is disconnected before performing any installation, wiring, or maintenance.
• მონტაჟი უნდა განხორციელდეს კვალიფიციური პერსონალის მიერ, რომელიც კარგად იცნობს ელექტრო და სანტექნიკურ სისტემებს.
• Do not exceed the maximum working pressure of 1.0 MPa.
• შეამოწმეთ სწორი ტომიtage (DC9V-24V) and control signal type before connecting.
• Protect the valve from extreme temperatures and corrosive environments.

4.1 გაყვანილობის დიაგრამა

The valve uses a 5-wire control method. Refer to the diagram below for correct wiring connections.

4.2 გაყვანილობის კავშირები

1. RD (Red Cable): Connect to DC9-24V positive pole.
2. BK (Black Cable): Connect to DC9-24V negative pole (also common for 4-20mA-/0-5V-/0-10V control signals).
3. GR (Green Cable): Connect to position input / control current + / control voltage + (for 4-20mA, 0-5V, or 0-10V signals).
4. WT (White Cable): Connect to common signal input and output signal's negative.
5. YW (Yellow Cable): Connect to position feedback positive, providing a 4-20mA feedback signal.

An additional YW connection is for an LED light (between 9-24V). This LED will illuminate if an error occurs.

4.3 ფიზიკური მონტაჟი

Mount the valve securely in the desired position within your plumbing system. Ensure the valve thread (NPT or BSP, depending on your model) matches your piping. The valve can operate in any position.

5. საოპერაციო ინსტრუქციები

The TFM8-B2-C proportional valve modulates its opening based on the input control signal (0-5V, 0-10V, or 4-20mA). The valve will move to the commanded position within approximately 7 seconds. A locked-rotor delay time of 2-4 seconds is integrated.

• საკონტროლო სიგნალი: გამოიყენეთ შესაბამისი ტtage or current signal to the GR (Green) wire relative to the BK (Black) wire to control the valve's opening percentage.
• პოზიციის გამოხმაურება: The YW (Yellow) wire provides a 4-20mA feedback signal indicating the current position of the valve.
• PWM გამომავალი: The WT (White) wire provides an OC output PWM signal with a frequency of 0-100Hz and a duty cycle of 5-95%.

6. მოვლა

The TFM8-B2-C valve is designed for low maintenance. Regular inspection is recommended to ensure optimal performance:

• Periodically check for any leaks around the valve body and connections.
• Ensure wiring connections remain secure and free from corrosion.
• Keep the actuator free from excessive dust or debris.
• No lubrication or internal adjustments are required for the actuator.

7. Დიაგნოსტიკა

If you encounter issues with your TFM8-B2-C valve, consider the following:

• Valve not responding: Check power supply (DC9-24V) and ensure control signal is correctly applied. Verify all wiring connections are secure.
• LED error light is ON: If the LED connected to the YW wire (error indicator) is illuminated, it signifies an internal error. Disconnect power, wait a few minutes, and reconnect. If the error persists, contact support.
• Inaccurate positioning: Verify the control signal source is stable and within the specified range (0-5V, 0-10V, or 4-20mA). Check the position feedback signal for consistency.
• ნელი ოპერაცია: დარწმუნდით, რომ კვების ბლოკიtage is adequate and stable.
