3. Operating Instructions

3.1. Display and Buttons

The controller features a dual digital display: PV (Process Value) shows the current measured temperature, and SV (Set Value) shows the target temperature. Control buttons include PRG (Program), COM (Communication), AT (Auto-tuning), RUN, STOP, and Up/Down arrows for value adjustment.

3.2. Control Modes

The AI-8 series supports two primary control methods:

PID Control: Proportional-Integral-Derivative control for precise and stable temperature regulation.
Position Control: A simpler control method, often used for basic on/off applications.

3.3. Alarm Functions

The controller can be configured with 1 to 4 alarm outputs, allowing for custom alarm types based on process requirements. Refer to the detailed programming manual for setting up alarm parameters.

3.4. Communication

For data acquisition and integration into larger control systems, the AI-8 series supports RS485 communication with both AIBUS and MODBUS dual communication protocols.

4. Maintenance

To ensure optimal performance and longevity of your Yudian AI-8 series temperature controller, follow these general maintenance guidelines:

Keep the unit clean and free from dust and debris. Use a soft, dry cloth for cleaning.
Ensure proper ventilation around the controller to prevent overheating.
Regularly check all wiring connections for tightness and signs of wear or corrosion.
Avoid exposing the controller to excessive moisture, extreme temperatures, or corrosive environments.
If the unit requires repair, contact qualified service personnel. Do not attempt to disassemble the controller yourself.

5. Troubleshooting

This section provides general guidance for common issues. For complex problems, consult the full technical manual or contact support.

Problem	Possible Cause	Solution
Controller does not power on	No power supply; incorrect wiring; blown fuse	Check power connections; verify wiring against diagram; replace fuse if necessary.
Inaccurate temperature reading	Sensor fault; incorrect sensor type selected; sensor not properly installed	Check sensor for damage; ensure correct input type is configured; verify sensor placement.
Output not activating	Incorrect set value (SV); output wiring error; control mode issue	Adjust SV; check output wiring; verify control mode and parameters.
