6.2. Электр схемасы

ЭСКЕРТҮҮ: All wiring should be performed by a qualified electrician and with the power supply disconnected to prevent electric shock. Ensure all connections are secure and comply with local electrical codes.

The ZL-7801A has multiple terminals for power, sensor input, and various load outputs (R1, R2, R3, R4, R5). Refer to the diagram below for correct wiring. The loads are based on resistive load ratings.

Figure 5: Detailed wiring diagram for the ZL-7801A controller. This diagram shows connections for the 100-240VAC power supply, the humidity and temperature sensor, and the five relay outputs (R1, R2, R3, R4, R5) with their respective Normally Open (NO), Normally Closed (NC), and Common (COM) terminals.

Терминал байланыштары:

• Power Supply (100-240VAC, 50/60Hz): Connect your main power input to the designated power terminals.
• Humidity & Temperature Sensor: Connect the sensor cable to the dedicated sensor input terminals. Ensure correct polarity if applicable.
• R1, R2, R3, R4, R5 (Relay Outputs): Each relay has Common (COM), Normally Open (NO), and Normally Closed (NC) terminals. Connect your controlled devices (e.g., heaters, humidifiers, fans) to the appropriate relay terminals based on your control logic.

7. Иштөө нускамалары

The ZL-7801A allows you to set desired temperature and humidity levels. The specific programming steps will depend on the desired control mode (e.g., heating, cooling, humidifying, dehumidifying). Refer to the full programming manual (if available) for advanced settings.

7.1. Күйгүзүү / Өчүрүү

Connect the controller to the power supply as per the wiring instructions. The display will illuminate, showing the current temperature and humidity readings from the sensor.

7.2. Basic Parameter Setting (Example: Temperature Setpoint)

While the exact sequence may vary for all parameters, a typical setting process involves:

1. Press and hold the 'S' button to view учурдагы коюлган чек.
2. Press the 'P' button to enter programming mode (or a combination of 'P' and 'S').
3. Use the '▲' and '▼' buttons to navigate through parameters or adjust values.
4. Press 'P' or 'S' again to confirm a setting and move to the next parameter or exit programming mode.

Consult the detailed programming guide for specific parameter codes and their functions (e.g., temperature hysteresis, humidity differential, alarm settings).

8. Техникалык тейлөө

To ensure optimal performance and longevity of your LILYTECH ZL-7801A controller, follow these maintenance guidelines:

• Тазалоо: Regularly wipe the front panel with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the display or casing.
• Сенсорго кам көрүү: Keep the temperature and humidity sensor clean and free from dust or debris. Ensure it is not exposed to direct water spray or extreme physical impact.
• Экологиялык шарттар: Operate the controller within the specified working environment temperature and humidity ranges to prevent damage. Avoid locations with excessive vibration, corrosive gases, or strong electromagnetic interference.
• Туташуу текшерүүлөрү: Periodically inspect all wiring connections to ensure they remain tight and secure. Loose connections can lead to erratic behavior or damage.

9. Кыйынчылыктарды

If you encounter issues with your ZL-7801A controller, refer to the following common problems and solutions:

• Контроллер күйбөйт:
  • Check the power supply connections to ensure they are correctly wired and receiving the specified voltage (100-240Vac).
  • Кубат булагы активдүү экенин текшериңиз.
• Display shows abnormal readings or 'Err' message:
  • Check the temperature and humidity sensor connection. Ensure it is securely plugged in and not damaged.
  • The sensor might be faulty. Try replacing it if possible.
  • Ensure the sensor is placed in an appropriate environment and not exposed to extreme conditions beyond its operating range.
• Controlled device (e.g., heater, humidifier) is not activating:
  • Verify the wiring of the controlled device to the correct relay output (R1-R5) terminals (COM, NO, NC).
  • Check the setpoints for temperature and humidity to ensure they are configured to trigger the device under current conditions.
  • Ensure the controlled device itself is functional and powered.
  • Review the controller's programming parameters (e.g., hysteresis, delay settings) which might prevent immediate activation.
• Баскычтар жооп бербейт:
  • Ensure the controller is not in a locked mode (if such a feature exists, refer to the full manual).
  • Power cycle the device by disconnecting and reconnecting the power supply.
