4. Setup

4.1 Installation

The TCN4S-24R is designed for panel mounting in a standard 1/16 DIN cutout (45x45mm). Ensure adequate space for ventilation and wiring connections at the rear of the unit. Secure the controller using the provided mounting brackets.

• Cut a panel opening of 45mm x 45mm.
• Insert the controller into the opening from the front.
• Attach the mounting brackets to the sides of the controller and tighten the screws to secure it firmly in place.

4.2 Wiring Connections

Refer to the wiring diagram on the side of the unit and the detailed terminal view for correct connections. Ensure all power is disconnected before performing any wiring.

Key Terminal Connections:

• Terminals 1 & 2: SSR OUT (12VDC ±2V, 20mA Max) / AL1 OUT (250VAC 1A1a) - Note: These terminals are shared for SSR output and Alarm 1. Configuration determines function.
• Terminals 3 & 4: Relay OUT (250VAC 3A1a)
• Terminals 7 & 8: AL2 OUT (250VAC 1A1a)
• Terminals 9, 10, 11: TC (Thermocouple) / RTD (Resistance Temperature Detector) Input. Connect sensor according to type (e.g., K-type thermocouple to 9 and 10, RTD to 9, 10, 11).
• Terminals 5 & 6: Power Supply (100-240VAC, 50/60Hz)

Caution: Incorrect wiring can damage the unit or connected equipment. Always consult the wiring diagram and ensure proper polarity and voltage.

5. Operating Instructions

5.1 Basic Operation

Upon power-up, the controller will display the Process Value (PV) on the upper display and the Set Value (SV) on the lower display.

• PV (Process Value): Shows the current measured temperature.
• SV (Set Value): Shows the desired target temperature.
• MODE Button: Used to cycle through parameters and enter setting modes.
• Up/Down Arrows: Used to adjust numerical values in setting modes.
• Left Arrow: Used to shift cursor position during numerical input.

5.2 Setting the Set Value (SV)

1. Press the MODE button briefly until the SV display starts flashing.
2. Use the Up and Down arrow buttons to adjust the SV to the desired temperature. Use the Left arrow to move between digits.
3. Press the MODE button again to confirm the setting and exit the SV adjustment mode. The SV display will stop flashing.

5.3 Advanced Settings (PID Parameters, Alarm Settings)

To access advanced settings such as PID parameters, input type, and alarm configurations, press and hold the MODE button for several seconds until the parameter menu appears. Navigate through the parameters using the MODE button and adjust values with the arrow buttons. Refer to the full manufacturer's manual for detailed parameter descriptions and adjustment procedures.

6. Maintenance

The CEMELI TCN4S-24R Temperature Controller is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure longevity:

• Cleaning: Periodically clean the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Inspection: Regularly inspect wiring connections for looseness or signs of damage. Ensure the unit is free from dust and debris, especially around ventilation slots.
• Environment: Operate the controller within its specified environmental conditions (temperature, humidity) to prevent malfunction.

Warning: Disconnect all power before performing any cleaning or inspection that involves opening the unit or accessing internal components.
