Standards met: IS/IEC 60034-1, IS 1460, ISO 8528, ISO 3046, IS 13018, ISO 9001. Digital control panel: Digital electronic control. Push-button selection for operating modes: MANUAL/ START/ STOP/ AUTO. Emergency stop switch. Connects to ATS (remote start/stop). Operates in Manual/ Auto or equivalent modes. The reset function clears errors. It integrates synchronization and load sharing functions between generators, and the ability to add or remove generators based on increasing or decreasing load to save fuel. The control panel has a digital display (LCD), LEDs, and backlighting. It displays phase-to-phase (LL), neutral (LN), and all three phases simultaneously. The following parameters are measured and displayed: Current per phase and current of all three phases; Power (kW, kVAR, kVA) for all three phases and total; Power factor for all three phases and total; Frequency; Battery voltage; Engine speed; Coolant temperature; Engine oil pressure; Oil temperature; Engine RPM; Operating hours; Number of starts; Displays the percentage of adjustability of the voltage regulator and speed controller; Displays Bus voltage, Bus frequency, and Bus current during synchronization; Displays fuel consumption rate, amount of fuel consumed, and total fuel consumed by the generator; Indicates each error using letters, codes, or other symbols and predictions. The control panel displays troubleshooting instructions and parameters on the screen. It includes software to protect the generator from overcurrent, overload, and short circuits (based on over-temperature and over-current characteristics over time), as well as protecting the generator under load (catalog required). Warning and protection functions: Low battery; High/low DC voltage; Overspeed/underspeed; Low/high oil pressure; High/low coolant temperature; Low coolant level; Low fuel level; Sensor malfunction; Engine cranking but not starting; High/low AC voltage; High/low frequency; Reverse active and reactive power protection; Emergency stop. All voltage, frequency, and setting adjustments are performed via the LCD display or dedicated software (rotary potentiometer adjustments are not permitted). Parameter adjustment functions: Voltage can be increased/decreased on the control panel; Frequency (speed) can be increased/decreased.
