5.2 Laidai

WARNING: Ensure power is disconnected before performing any wiring.

Refer to the wiring diagram printed on the side label of the controller for accurate connections. A typical wiring configuration is as follows:

5.2 paveikslas: Wiring Diagram on Product Label. This image provides a close-up of the REX C100's side label, which includes a comprehensive wiring diagram for power, sensor input, and output connections.

• Power Supply (Terminals 1 & 2): Connect your 100-240VAC, 50/60Hz power source here.
• Output (OUT1) (Terminals 3, 4, 5): These are relay contacts. Connect your heating or cooling element through these terminals. The diagram shows Normally Open (NO) and Common (COM) connections.
• Alarm 1 (ALM1) (Terminals 6 & 7): Connect external alarm devices here.
• Alarm 2 (ALM2) (Terminals 8 & 9): Connect external alarm devices here.
• Sensor Input (Terminals 10 & 11): Connect your K-type thermocouple here. Ensure correct polarity for accurate readings.

After wiring, double-check all connections before applying power.

6. Naudojimo instrukcijos

6.1 Įjungimas

Once wired correctly, apply power to the controller. The PV display will show the current temperature measured by the thermocouple, and the SV display will show the set target temperature.

6.2 Setting the Target Temperature (SV)

1. Paspauskite NUSTATYTI button once. The SV display will begin to flash.
2. Naudokite Up ir Žemyn arrow buttons to adjust the target temperature. The Kairė arrow button can be used to shift the cursor for faster adjustment of individual digits.
3. Paspauskite NUSTATYTI 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.

6.3 PID Auto-Tuning

The REX C100 features an expert self-tuning PID function. Auto-tuning helps the controller learn the characteristics of your specific heating/cooling system to optimize control performance and minimize overshoot or undershoot.

To initiate auto-tuning:

1. Ensure the system is at a stable temperature, preferably near your desired set point.
2. Paspauskite ir palaikykite NUSTATYTI button for approximately 3-5 seconds until the controller enters the parameter setting menu.
3. Navigate through the parameters (using arrow keys) until you find the auto-tuning parameter (often labeled 'AT' or similar).
4. Set the auto-tuning parameter to '1' (or 'ON') and confirm with the NUSTATYTI button. The 'AT' indicator light on the front panel will illuminate.
5. The controller will cycle the output to determine the optimal PID parameters. This process may take some time (e.g., several heating/cooling cycles).
6. Once auto-tuning is complete, the 'AT' indicator will turn off, and the controller will operate with the newly optimized PID parameters.

Note: Specific parameter codes and navigation may vary slightly. Refer to the detailed programming manual (if available) for advanced settings.

6.4 Signalizacijos nustatymai

The REX C100 includes two alarm outputs (ALM1, ALM2). These can be configured for various alarm types (e.g., high limit, low limit, deviation) and hysteresis. Access these settings through the parameter menu by pressing and holding the NUSTATYTI mygtuką.

7. Priežiūra

• Valymas: Priekinį skydelį valykite minkštu, sausu skudurėliu. Nenaudokite abrazyvinių valiklių ar tirpiklių.
• Aplinkosaugos patikrinimas: Periodically inspect the operating environment to ensure it remains free of corrosive gases, excessive dust, and moisture.
• Ryšio patikrinimas: Occasionally check wiring connections for tightness, especially in environments with vibration.
• Jutiklio patikrinimas: Inspect the thermocouple for any signs of damage or corrosion that could affect accuracy.
