Salient features of the DGC-7

Protection & Supervision:

3 phase Under & Over, voltage, frequency and voltage unbalance protection for EB supply (True RMS measurement for Voltage)
Phase under & over, voltage and frequency protection of Generator supply (True RMS measurement for voltage)
User programmable Cranking attempt.
User programmable Crank Time and delay between two successive cranks
User programmable load transfer to DG delay.
Generator over speed supervision
Mains Restoration supervision
DC Battery Voltage supervision (Under & Over voltage)
External fault detection (5 digital inputs)
Two Circuit breaker check back inputs.
External engine running signal
External signal for remote operation
DG Fail to start supervision and indication
DG fail to stop supervision and indication
Unit remains fully operational even if battery voltage falls to zero volts for one sec.

Measurement & Display

DGC-7, equipped with 16 Segment, 21ine LCD display, displays:

EB voltages of RYB phase and frequency
Generator voltage and frequency
DC battery voltage
Run Hour time

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.

Setting Table

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
