The rear of the unit provides screw terminals for power input, control output, and sensor input. Refer to the wiring diagram in the Setup section for detailed connections.

5. Nastavení a zapojení

Before proceeding with wiring, ensure that the main power supply is disconnected to prevent electrical shock.

5.1 Montáž regulátoru

The REX-C100 is designed for panel mounting. Cut an appropriate opening in your control panel according to the dimensions provided in Figure 5.1. Secure the controller using the provided mounting brackets.

Figure 5.1: Dimensions of the REX-C100 controller. The front panel measures approximately 4.6cm (1.81in) by 4.6cm (1.81in), and the depth is approximately 10.5cm (4.13in).

5.2 Elektrické zapojení

Refer to the wiring diagram below for correct connections. Incorrect wiring can damage the device or connected equipment.

Figure 5.2: Detailed wiring diagram for the REX-C100. It illustrates connections for working voltage (100-240V), alarm light/buzzer output, heating tube, solid state relay, K-type thermocouple (two wires), and RTD (3-wire) sensor. Note the short connection for the solid state relay control.

1. Napájení (svorky 1 a 2): Connect 100-240V AC power to terminals 1 and 2.
2. Control Output (Terminals 3, 4, 5):
   • For relay output, connect your load (e.g., heating element via a Solid State Relay) to these terminals as per the diagram.
   • If using an SSR, connect the SSR control input to the appropriate output terminals (e.g., 4(+) and 5(-)).
3. Sensor Input (Terminals 8, 9, 10):
   • For K-type thermocouple (two wires), connect to terminals 9 and 10.
   • For RTD (3-wire) sensor, connect A to terminal 8, B/B to terminals 9 and 10.
4. Alarm Output (Terminals 6 & 7): Connect an alarm device (e.g., alarm light or buzzer) to terminals 6 and 7 if alarm functionality is desired.

Důležité: Před připojením napájení vždy dvakrát zkontrolujte všechna připojení.

6. Návod k obsluze

Once the controller is wired and powered on, the PV display will show the current temperature, and the SV display will show the set temperature.

6.1 Setting the Target Temperature (SV)

1. Stiskněte tlačítko SOUBOR button once. The SV display will start flashing.
2. Použijte Up (▲) a Dolů (▼) tlačítky se šipkami nastavte požadovanou teplotu.
3. Použijte Vlevo (◀) arrow button to shift the cursor for faster adjustment of digits.
4. Stiskněte tlačítko SOUBOR button again to confirm the new SV and exit the setting mode.

6.2 Parameter Settings (Advanced)

To access advanced parameters (e.g., PID parameters, alarm settings, input type), press and hold the SOUBOR button for approximately 3-5 seconds until the first parameter code appears on the PV display.

• Použijte SOUBOR button to cycle through parameters.
• Použijte Up a Dolů arrow buttons to change the value of the selected parameter.
• To exit parameter setting mode, press and hold the SOUBOR button again, or wait for the controller to automatically exit after a period of inactivity.

Poznámka: Refer to the detailed parameter list in the full technical manual for specific parameter codes and their functions. Incorrect parameter settings can lead to unstable control or damage.

6.3 Auto-Tuning Function

The auto-tuning (AT) function automatically calculates optimal PID parameters for your specific heating system. This helps achieve stable and accurate temperature control.

1. Set your desired target temperature (SV).
2. Access the parameter settings (hold SOUBOR).
3. Locate the auto-tuning parameter (often labeled "AT" or similar).
4. Set the auto-tuning parameter to "ON" or "1". The AT indicator will light up.
5. The controller will cycle the output to analyze the system's response. This process may take some time.
6. Once auto-tuning is complete, the AT indicator will turn off, and the calculated PID parameters will be saved.

Pozor: During auto-tuning, the temperature may overshoot or undershoot the set value. Ensure this will not damage your process or materials.

7. Údržba

The REX-C100 is designed for reliable operation with minimal maintenance. However, periodic checks can help ensure its longevity and accuracy.

• Čištění: Jemně otřete přední panel měkkým, suchým hadříkem. Nepoužívejte abrazivní čisticí prostředky ani rozpouštědla.
• Připojení terminálu: Periodically check all wiring connections for tightness, especially in environments with vibration.
• Integrita senzoru: Inspect the temperature sensor and its wiring for any signs of damage or corrosion. Replace if necessary.
• Větrání: Ensure that the ventilation slots on the controller are not obstructed to allow for proper heat dissipation.
