Measurement & Display
DGC-7, equipped with 16 Segment, 21ine LCD display, displays:
Programmed values
The display shows the mains voltage parameters while the mains is healthy and automatically switches over to display the generator parameters while the generator is running.
Parameter Name on First Row of LCD | Explanation of parameter | Factory setting | Setting Range |
Mains O/V | Max. Permissible voltage, above this the voltage is treated unhealthy & Generator is started. | 270V | 80-270V |
Mains U/V | Min. permissible voltage, below this the voltage is treated unhealthy & Generator is started | 180V | 80-270V |
Mains Sup Delay | Time for which the mains voltage has to be unhealthy (under or over voltage as defined above in l & 2) before starting the generator. | 10Sec | 0-999Sec |
Mains O/F | Max. permissible mains frequency, above this frequency the mains is treated unhealthy & Generator is started. | 55Hz | 40-65Hz |
Mains U/F | Min. permissible mains frequency, below this frequency the mains is treated unhealthy & Generator is started. | 45Hz | 40-65Hz |
Mains Freq Delay | Time for which the mains frequency as to be unhealthy (under or over voltage as defined above in 4 & 5) before starting the generator.. | 10Sec | 0-999Sec |
Mains Vol Unbal | Max. permissible voltage difference between two phases of mains. Above this the voltage is treated to be unbalanced and generator is started. | 40 | 10-100 Disable |
Unbalance Delay | Duration for which unbalance can be tolerated before starting the Generator. | 10Sec | 0-999Sec |
Generator O/V | Max. permissible generator voltage, above this the generator voltage is treated unhealthy & the generator is stopped. Generator contactor is released and mains contactor is closed. Hooter shall be activated and DG Vol LED shall start flashing. | 270V | 80-270V |
Generator U/V | Min. permissible generator voltage, below this the generator voltage is treated unhealthy & the generator is stopped. Generator contactor is released and mains contactor is closed. Hooted shall be activated and DG Vol LED shall start flashing. | 180V | 80-270V |
