3. Product Overview
The UOFKIPBA WINPARK AK6 PID Temperature Controller is a compact and reliable device for accurate temperature regulation. It features a clear digital display for process value (PV) and set value (SV), along with indicator lights for output and alarm status. The controller supports various input types and offers multiple control outputs.
3.1 Front and Side View
3.2 Rear Terminal Connections
4. Installation
4.1 Mounting
The AK6 controller is designed for panel mounting. Ensure the panel cutout dimensions are 48x96mm. Secure the controller using the provided mounting brackets.
- Cut a rectangular opening of 48mm x 96mm in the mounting panel.
- Insert the controller into the opening from the front.
- Attach the mounting brackets to the sides of the controller from the rear of the panel and tighten the screws to secure it firmly.
4.2 Wiring
Refer to the wiring diagram on the side of the controller (Figure 1) and the rear terminal block (Figure 2) for correct connections. Ensure all connections are secure and insulated.
- Power Supply (AC): Connect the AC power supply to terminals 8 and 9. Verify the voltage matches the controller's specifications.
- SSR Output 1 (OUT1/ALM1): Connect the Solid State Relay (SSR) control input for the primary output to terminals 10 and 11.
- SSR Output 2 (OUT2/ALM2): Connect the SSR control input for the secondary output or alarm 2 to terminals 12 and 13.
- Temperature Sensor Input (TEMP): Connect your temperature sensor (e.g., thermocouple, RTD) to terminals 14 (V-) and 15 (V+). Ensure correct polarity for thermocouples.
- Alarm Output (ALM1/ALM2): If using relay alarms, connect to the appropriate terminals as indicated on the wiring diagram.
Note: The specific terminal assignments may vary slightly depending on the exact model variant (e.g., relay output vs. SSR output). Always consult the diagram printed on your specific unit.
5. Initial Setup and Configuration
After successful installation and wiring, power on the controller. The display will show the current Process Value (PV) and Set Value (SV).
5.1 Setting the Set Value (SV)
- Press the SET button once. The SV display will begin to flash.
- Use the Up (▲) and Down (▼) arrow buttons to adjust the desired set temperature.
- Press SET again to confirm the new SV and exit the setting mode.
5.2 Accessing Parameter Settings
To access advanced parameters (e.g., input type, control mode, PID parameters), press and hold the SET button for approximately 3-5 seconds until the first parameter code appears on the PV display.
- Use the SET button to cycle through different parameters.
- Use the Up (▲) and Down (▼) arrow buttons to change the value of the currently displayed parameter.
- To save changes and exit, stop pressing buttons for several seconds, or cycle through all parameters until the controller returns to normal operation.
Note: Consult the detailed parameter list (usually provided in a separate sheet or advanced manual) for specific parameter codes and their functions. Incorrect parameter settings can lead to unstable control or damage.
6. Operating Instructions
6.1 Auto-Tuning (AT) Function
The auto-tuning function helps the controller automatically determine optimal PID parameters for your specific system, ensuring stable and accurate temperature control.
- Set your desired Set Value (SV).
- Press and hold the AT button for approximately 3-5 seconds. The AT indicator light will illuminate, indicating auto-tuning is in progress.
- During auto-tuning, the system temperature will cycle around the SV. Allow the process to complete without interruption.
- Once auto-tuning is finished, the AT indicator will turn off, and the controller will operate with the newly calculated PID parameters.
Caution: Auto-tuning may cause temporary temperature fluctuations. Ensure this is acceptable for your application before initiating.
6.2 Manual Control (MAN)
In some cases, manual control of the output power may be desired.
- Press the MAN button to switch to manual control mode. The MAN indicator will illuminate.
- Use the Up (▲) and Down (▼) arrow buttons to adjust the output power percentage.
- Press MAN again to exit manual mode and return to automatic control.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your temperature controller.
- Cleaning: Periodically clean the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Regularly check wiring connections for looseness or signs of damage. Ensure the controller's ventilation slots are not obstructed.
- Environment: Maintain the operating environment within the specified temperature and humidity ranges.
8. Troubleshooting
This section provides solutions to common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller does not power on. | No power supply; incorrect wiring; blown fuse. | Check power connections (terminals 8 & 9). Verify power source. Inspect internal fuse if accessible (consult service). |
| PV display shows "HHHH" or "LLLL". | Sensor open circuit; sensor short circuit; incorrect sensor type setting. | Check sensor wiring (terminals 14 & 15). Replace faulty sensor. Verify sensor type in parameter settings. |
| Temperature control is unstable or oscillates. | Incorrect PID parameters; system disturbance. | Perform auto-tuning (Section 6.1). Check for external factors affecting temperature stability. |
| Output does not activate. | Output wiring error; output type mismatch; controller in manual mode with 0% output. | Verify output wiring (terminals 10-13). Check output type setting in parameters. Ensure controller is in auto mode or manual output is set above 0%. |
