6. Nastavení a instalace

6.1 Schéma zapojení

Refer to the following wiring diagram for proper connection of the REX-C100 controller, SSR, and K-type thermocouple to your AC power supply and heating element.

Wiring diagram for REX-C100 PID controller kit

Image 6.1: Detailed wiring diagram for connecting the REX-C100 controller, SSR, and K-type sensor to an AC power supply and heating element.

  • Napájení (AC): Connect your AC power supply (100-240VAC) to terminals 1 and 2 of the REX-C100 controller.
  • SSR Control Output: Connect the SSR control output from the REX-C100 (terminals 4 and 5) to the control input of the SSR (3-32VDC side). Ensure correct polarity (+ to + and - to -).
  • Vstup termočlánku: Connect the K-type thermocouple to terminals 9 and 10 of the REX-C100. The red wire typically connects to the positive (+) terminal (9), and the blue wire to the negative (-) terminal (10).
  • SSR Load Connections: Connect your heating element (load) to the output terminals of the SSR (24-480VAC side). Connect one line of your AC power supply to one input terminal of the SSR, and the other input terminal of the SSR to one side of your heating element. Connect the other side of your heating element directly to the other line of your AC power supply.

6.2 Fyzická instalace

  • Mount the REX-C100 controller into a panel cutout of 45x45mm using the provided mounting bracket.
  • Securely mount the SSR to a heat sink if the load current is significant, to dissipate heat and ensure longevity.
  • Install the K-type thermocouple at the desired temperature measurement point within your system, ensuring good thermal contact.

7. Návod k obsluze

7.1 Základní obsluha

  • Zapnutí: After completing all wiring, apply power to the controller. The PV display will show the current temperature, and the SV display will show the set temperature.
  • Setting Temperature (SV):
    1. Stiskněte tlačítko SOUBOR button once. The SV display will begin to flash.
    2. Použijte Nahoru (^) a Dolů (v) keys to adjust the desired temperature. Use the Displacement Key (<) to move the cursor for faster adjustment.
    3. Stiskněte tlačítko SOUBOR button again to confirm the new set value. The SV display will stop flashing.
  • The controller will now work to maintain the PV at the SV, activating the SSR output as needed.

7.2 PID Tuning

For optimal performance, especially in systems with varying loads or requiring high precision, PID auto-tuning may be necessary. Consult the full REX-C100 manual for detailed PID parameter settings and auto-tuning procedures. Generally, auto-tuning involves:

  • Entering the parameter setting mode (usually by holding the SET button).
  • Locating the auto-tune parameter (often labeled 'AT' or similar).
  • Activating auto-tune, which will cause the controller to cycle the output to determine optimal PID values.
  • Saving the new parameters after auto-tuning is complete.

9. Údržba

  • Pravidelně kontrolujte veškeré kabelové spoje, zda nejsou těsné a zda nevykazují známky opotřebení nebo koroze.
  • Keep the controller and SSR free from dust and debris. Use a soft, dry cloth for cleaning.
  • Ensure adequate ventilation around the SSR, especially if operating at high loads, to prevent overheating.
  • Periodically check the thermocouple for physical damage or degradation, which can affect temperature readings.
