6. Istruzzjonijiet Operattivi
6.1 Mixgħul
After completing all wiring, apply power to the meter. The LED displays will illuminate, showing the current Process Value (PV) and potentially a Set Value (SV).
6.2 Funzjonijiet tal-buttuni
- Buttuna SET: Użat biex tidħol fil-modalità tal-issettjar tal-parametri u tikkonferma l-għażliet.
- <<RST button: Used to shift digits during value setting or to reset certain functions.
- Up (↑) button: Used to increase values or navigate through menu options.
- Down (↓) button: Used to decrease values or navigate through menu options.
6.3 Basic Operation (General)
While specific programming steps are not detailed in the provided information, typical operation involves:
- ViewPV/SV tal-ing: The main display shows the current Process Value (PV). The smaller display shows the Set Value (SV), which might be an alarm setpoint or other configured parameter.
- Parametri tal-issettjar: Press the SET button to enter the parameter setting mode. Use the Up/Down arrows to select parameters and adjust their values. Use the <<RST button to shift between digits when setting numerical values. Press SET again to confirm and save changes.
- Funzjoni ta' allarm: The AL1 and AL2 indicators will light up when the measured PV exceeds or falls below their respective setpoints, triggering the corresponding relay outputs.
For detailed parameter configuration, refer to the full product manual (if available from the manufacturer) or contact technical support.
