4.2 Wiring Diagram
WARNING: Ensure all power is disconnected before performing any wiring. Incorrect wiring can lead to equipment damage or personal injury. If you are unsure, consult a qualified electrician.
Refer to the wiring diagrams below for proper connection of the PID controller, SSR, and thermocouple. The controller requires AC 100-240V power supply.
Figure 4.3: Back panel of the PID controller showing terminal assignments for power (1, 2), SSR output (3, 4), alarm output (5, 6), and thermocouple input (11, 12).
Figure 4.4: Example physical wiring diagram for connecting the SSR 40DA to the PID controller and a heating element. Terminals 1 and 2 on the SSR connect to the AC load (heater), and terminals 3 and 4 connect to the DC control output (3-32VDC) from the PID controller.
Wiring Notes:
- Connect the K-Type Thermocouple to terminals 11 and 12. Ensure correct polarity (positive to 12, negative to 11).
- Connect the main AC power supply (100-240V) to terminals 1 and 2 of the PID controller.
- Connect the SSR control output from the PID controller (terminals 3 and 4) to the input terminals (3-32VDC) of the SSR 40DA.
- Connect the AC load (e.g., heater) to the output terminals (24-380VAC) of the SSR 40DA.
- The alarm output (terminals 5 and 6) can be connected to an external alarm device if required.
5. Operating Instructions
5.1 Display and Control Panel
The front panel of the PID controller features a digital display and control buttons:
Figure 5.1: Front panel layout of the SINOTIMER PID Temperature Controller, indicating PV/SV displays, control indicators, and function keys.
- PV (Process Value) Display: Shows the current measured temperature.
- SV (Set Value) Display: Shows the target temperature or parameter setting value.
- OUT Indicator: Lights up when the control output (to SSR) is ON.
- AT Indicator: Blinks when the self-tuning function is active.
- AL1 Indicator: Lights up when the alarm output is ON.
- MODE Key: Used to enter parameter settings and navigate between modes. Press and hold to store set values.
- Shift Key (<): Used for digit shifting during value adjustment.
- Decrease Key (↓): Used to decrease values.
- Increase Key (↑): Used to increase values.
5.2 Setting the Target Temperature (SV)
- In normal operation mode, the upper display shows PV (current temperature) and the lower display shows SV (target temperature).
- Use the Increase (↑) and Decrease (↓) keys to adjust the SV to your desired temperature.
- Use the Shift (<) key to move the cursor between digits for faster adjustment.
- The new SV will be automatically saved after a few seconds of inactivity or by pressing the MODE key.
5.3 Advanced Parameter Settings
To access advanced settings (e.g., PID parameters, alarm settings, input type, unit selection), press and hold the MODE key for several seconds. Use the MODE key to cycle through parameters, and the Shift (<), Increase (↑), and Decrease (↓) keys to adjust values. Refer to the detailed parameter list in the full product manual for specific functions and ranges.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your PID temperature controller kit.
- Cleaning: Periodically clean the controller's front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Regularly check all wiring connections for tightness and signs of wear or damage. Ensure the thermocouple is securely in place and free from corrosion.
- Heat Sink: Verify that the heat sink on the SSR is free from dust and debris to ensure efficient heat dissipation.
- Environment: Ensure the controller is operated within its specified environmental conditions (temperature, humidity) to prevent malfunction.
7. Troubleshooting
If you encounter issues with your PID temperature controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller does not power on | No power supply; incorrect wiring | Check power connections (terminals 1 & 2); ensure power source is active. |
| PV display shows 'HHHH' or 'LLLL' | Thermocouple open circuit or reverse connection; temperature exceeds range | Check thermocouple wiring and polarity; ensure it's within operating range. |
| Output (OUT indicator) not activating | SV not set correctly; PID parameters incorrect; SSR faulty | Verify SV is below PV (for heating); check PID settings; test SSR functionality. |
| Temperature unstable or overshoots | PID parameters not optimized | Perform auto-tuning (AT function) or manually adjust PID parameters. |
If the problem persists after attempting these solutions, please contact SINOTIMER customer support for further assistance.
