4. Bezpečnostní informace

Please read and understand all safety instructions before installing or operating this device. Failure to follow these instructions may result in electric shock, fire, or personal injury.

• Elektrické nebezpečí: Toto zařízení pracuje s vysokou hlasitostítage. All wiring should be performed by a qualified electrician or knowledgeable individual. Ensure power is disconnected before making any connections.
• Správné uzemnění: Ensure the device and any connected equipment are properly grounded.
• Větrání: Install the controller in a location with adequate ventilation to prevent overheating.
• Podmínky prostředí: Do not expose the device to moisture, corrosive gases, or extreme temperatures outside its specified operating range.
• Kapacita zatížení: Nepřekračujte maximální proud a objtage ratings of the Solid State Relay (SSR) or the controller's output.

5. Instalace a zapojení

Proper installation and wiring are critical for the safe and effective operation of the temperature control system. Refer to the wiring diagram on the back of the controller for specific terminal connections.

5.2. Připojení vodičů

Refer to Image 5.1 for the terminal layout. Ensure all connections are secure and correctly polarized where applicable.

1. Napájení (svorky 1 a 2): Connect AC100-240V power to these terminals.
2. K-Type Thermocouple (Terminals 8 & 9): Connect the K-type thermocouple probe to these terminals. Ensure correct polarity (positive to positive, negative to negative) for accurate readings.
3. Solid State Relay (SSR) Output (Terminals 4 & 5): These terminals provide the control signal (DC 3-32V) to the SSR. Connect Terminal 4 to the negative input of the SSR and Terminal 5 to the positive input of the SSR.
4. SSR Load Connections: Connect the load (e.g., heating element) to the output terminals of the 40A SSR. Connect the main AC power supply to the SSR's input terminals. Ensure the load's current and voltage requirements do not exceed the SSR's ratings.

6. Provoz

Once wired and powered on, the controller will display the current process value (PV) and the set value (SV).

6.1. Základní nastavení teploty

1. Stiskněte tlačítko SOUBOR button once. The SV display will begin to flash.
2. Použijte Up (▲) a Dolů (▼) arrow buttons to adjust the desired temperature (SV).
3. Stiskněte tlačítko SOUBOR button again to confirm the new SV. The display will stop flashing, and the controller will begin to regulate the temperature to the new set point.

6.2. Advanced Settings (PID Parameters)

To access advanced settings for PID tuning, press and hold the SOUBOR button for approximately 3-5 seconds until the parameter menu appears. Use the SOUBOR button to cycle through parameters and the arrow buttons to adjust values. Refer to the controller's detailed programming manual (if available) for specific parameter definitions and tuning procedures.

• Self-Tuning: The controller supports self-tuning control to optimize PID parameters for your specific application. Activate self-tuning from the advanced settings menu.
• Heating/Refrigeration Mode: The controller can be configured for either heating or refrigeration control. This setting is typically found in the advanced parameter menu.
• Ochrana proti zpoždění kompresoru: For refrigeration applications, a compressor delay protection function is available to prevent rapid cycling of the compressor.

7. Údržba

The Walfront PID REX-C100 Temperature Controller Kit requires minimal maintenance. Regular checks can ensure optimal performance and longevity.
