3. Product Overview
The AUTONICS TK4W-14RR features a clear front panel display and intuitive controls for monitoring and adjusting temperature parameters.
Figure 1: Front panel of the AUTONICS TK4W-14RR Temperature Controller. The image displays the dual digital display, with the upper red display showing the Process Value (PV) and the lower green display showing the Set Value (SV). Indicators for OUT1, OUT2, AL1, AL2, MAN, SV1, SV2, SV3, AT, %°F, and °C are visible. Control buttons for up, down, left/right arrow, and A/M MODE are located on the right side.
3.1. Front Panel Components
- PV Display (Red): Shows the current process value (measured temperature).
- SV Display (Green): Shows the set value (target temperature).
- Output Indicators (OUT1, OUT2): Illuminate when the respective relay outputs are active.
- Alarm Indicators (AL1, AL2): Illuminate when alarm conditions are met.
- Control Buttons: Used for navigating menus, adjusting values, and changing operating modes.

5. Setup
5.1. Installation
- Cut a panel cutout of W92xH45mm for mounting.
- Insert the TK4W-14RR into the cutout from the front.
- Secure the unit using the provided mounting brackets from the rear.
5.2. Wiring
Refer to the wiring diagram provided with your unit for specific terminal connections. Ensure all connections are secure and correctly polarized.
- Power Supply: Connect 100-240VAC to the designated power terminals.
- Sensor Input: Connect your temperature sensor (e.g., RTD, Thermocouple) to the input terminals. Ensure correct polarity for thermocouples.
- Control Outputs (OUT1, OUT2): Connect your heating/cooling elements or other control devices to the relay output terminals. Observe maximum current ratings.
- Alarm Output (AL1): Connect external alarm devices if required.
6. Operating
6.1. Power On
Once wired correctly, apply power to the unit. The PV display will show the current temperature, and the SV display will show the last set target temperature.
6.2. Setting the Set Value (SV)
- Press the MODE button briefly to enter SV setting mode. The SV display will flash.
- Use the Up and Down arrow buttons to adjust the SV to your desired temperature.
- Use the Left/Right arrow button to move the cursor for faster adjustment of individual digits.
- Press the MODE button again to confirm the new SV and return to normal operation.
6.3. Auto-Tuning (AT)
The Auto-Tuning function automatically calculates optimal PID parameters for your specific process. This is recommended for initial setup or if process characteristics change significantly.
- Ensure the SV is set to the desired operating temperature.
- Refer to the detailed parameter manual for entering the parameter setting mode.
- Locate the Auto-Tuning (AT) parameter and activate it. The AT indicator will flash.
- The controller will cycle the output to determine the process characteristics. This may take some time.
- Once complete, the AT indicator will turn off, and the newly calculated PID parameters will be applied.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your TK4W-14RR controller.
- Cleaning: Wipe the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check wiring connections for looseness or damage.
- Environment: Ensure the operating environment remains within specified temperature and humidity ranges.
8. Troubleshooting
This section addresses common issues you might encounter with the TK4W-14RR.
| Problem | Possible Cause | Solution |
|---|---|---|
| PV display shows 'HHHH' or 'LLLL' | Sensor open circuit or short circuit; sensor input out of range. | Check sensor wiring and connections. Verify sensor type matches controller settings. |
| Controller not heating/cooling | Output relay not activating; wiring issue to heater/cooler; SV set incorrectly. | Check OUT1/OUT2 indicators. Verify wiring to load. Adjust SV. Check output parameters. |
| Temperature oscillates widely | PID parameters are not optimized. | Perform Auto-Tuning (AT) or manually adjust PID parameters. |
| Display is blank | No power supply; incorrect wiring. | Check power connections and voltage. Ensure power is applied. |
