5.1 Funcions clau
- Tecla MODE: Used to enter parameter group settings, return to operating mode, switch between parameter groups, and save set values.
- Direction Keys (↑ / ↓): Used to enter the setting value change mode or move the digit position to adjust values up and down.
- Function Keys (↑ + ↓ simultaneously): Pressing these keys together for 3 seconds activates the [D1-K] digital input key function, which can include run/stop, alarm clear, or auto-tuning settings.
- Temperature Unit Indicator Light (℃ / ℉): Displays the currently selected temperature unit.
5.2 Funcionament bàsic
- Encès: After proper wiring, apply power to the unit. The display will illuminate, showing the current process value (PV) and set value (SV).
- Configuració de la temperatura: Use the MODE key to navigate to the set value (SV) adjustment. Use the direction keys (↑ / ↓) to change the desired temperature. Press MODE again to confirm and save the setting.
- Configuració dels paràmetres: For advanced settings such as control method (PID, ON/OFF), input type, or alarm configurations, refer to the detailed parameter menu accessible via the MODE key. Consult the full technical manual for specific parameter codes and their functions.
6. Manteniment
To ensure optimal performance and longevity of your Srliya BEM-TC7A-14RV temperature controller, follow these general maintenance guidelines:
- Neteja: Regularly clean the display and housing with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Inspecció: Comproveu periòdicament totes les connexions del cablejat per comprovar si estan ben ajustades i si hi ha signes de desgast o corrosió.
- Medi ambient: Assegureu-vos que l'entorn de funcionament es mantingui dins dels rangs de temperatura i humitat especificats per evitar danys.
7. Solució De Problemes
If you encounter issues with your temperature controller, consider the following common troubleshooting steps:
- Sense pantalla: Check the power supply connections and ensure the rated voltage (100-240VAC) is applied correctly.
- Lectura de temperatura incorrecta: Verify that the sensor is correctly connected and that the input type setting in the controller matches your sensor type (e.g., K-type, J-type).
- Sortida no activable: Check the set temperature (SV) against the process value (PV) and ensure the control mode (e.g., heating/cooling) is correctly configured. Inspect output wiring.
- Unstable Control: If the temperature fluctuates excessively, consider performing an auto-tuning function or manually adjusting PID parameters.
For persistent issues, contact customer support for further assistance.
