4.1 Panel Mounting

1. Cut a panel cutout of 45x45 mm (1/16 DIN standard).
2. Insert the unit into the cutout from the front.
3. Secure the unit using the supplied mounting brackets from the rear.

4.2 Wiring

Refer to the wiring diagram on the side of the unit or in the detailed wiring section of the full manual for specific terminal connections. Ensure all connections are secure and correct before applying power.

• Power Supply: Connect 100-240VAC, 50/60 Hz to the designated power terminals.
• Sensor Input: Connect your temperature sensor (e.g., thermocouple, RTD) to the input terminals. Ensure correct polarity for thermocouples.
• Control Output: Connect your current output or SSR drive output to the appropriate terminals.
• Alarm Output: Connect the alarm output to your alarm device.
• RS485 Communication: Connect A and B terminals for RS485 communication if utilizing this feature.

5. Operating Instructions

Once installed and wired, the TK4S-T4CN is ready for operation. The unit features a clear dual display and intuitive button controls.

5.1 Display Overview

• PV (Process Value): The upper red display shows the current measured temperature.
• SV (Set Value): The lower green display shows the desired target temperature.
• Indicators: LEDs indicate output status (OUT1, OUT2), alarm status (AL1, AL2), and auto-tuning (AT).

5.2 Button Functions

• MODE Button: Used to cycle through parameter groups and enter/exit setting modes. Press and hold to enter parameter setting mode.
• Left Arrow (<) Button: Moves the cursor to the left during parameter setting, or used for specific function calls.
• Down Arrow (▼) Button: Decreases the value of a parameter or navigates through options.
• Up Arrow (▲) Button: Increases the value of a parameter or navigates through options.

5.3 Setting the Set Value (SV)

1. In normal operating mode, the lower green display shows the current SV.
2. Press the MODE button briefly to enter SV adjustment mode. The SV display will blink.
3. Use the <, ▼, and ▲ buttons to adjust the SV to your desired temperature.
4. Press the MODE button again to confirm the new SV and return to normal operating mode.

5.4 Control Modes (PID / ON/OFF)

The TK4S-T4CN supports both PID control for precise regulation and ON/OFF control for simpler applications. The control mode and associated parameters are configured in the parameter setting menu. Refer to the detailed manual for specific parameter settings for each control mode.

6. Maintenance

Regular maintenance ensures the longevity and reliable operation of your temperature controller.

• Cleaning: Gently wipe the display and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Environmental Conditions: Ensure the operating environment remains within specified temperature and humidity ranges to prevent damage.
• Connection Checks: Periodically inspect wiring connections for looseness or corrosion.
• Calibration: If accuracy issues are suspected, consult a qualified technician for calibration.
