8.0 Operation.
DES-P is an engine monitoring and supervisor unit.
The engine can be Started/Stopped from the front panel of DES-P or externally by means of key
Switch etc. The Start / stop from the front or remote is one touch operation, meaning that once the
switch is pressed the Crank/ fuel solenoid shall be operational till the “Crank Time / Stop Sol Time”
, as programmed, has expired . DES-P automatically detects that the engine on conditions by
monitoring engine speed . On detection of any of these faults for the pre-programmed duration the
engine is automatically shut down and fault along with run hour is recorded in non-volatile memory.
The run hour time of engine is recorded in internal non-volatile memory.
9.0 Setting Procedure
DES-P has provision to program the operating parameters, resetting the service hours and viewing
the last 20 fault history.

9.2 Fault History.
To view the last 20 fault history enters in this mode as explained above. Maximum of last 20
faults along with Run Hour stamp shall be displayed on the LCD. The first row shall display
the fault and the next row shall display the run hour at which the fault has occurred. The next
fault can be viewed by pressing “NEXT”. The mode shall exit to normal mode after the last
fault recording is displayed. Absence of any fault recoding shall not display any fault data.
9.3 Resting Service Hours.
Service due, warning is issued by DES-P, by flashing the Ser LED. This LED shall keep
flashing till it is not reset by entering this mode. Pls refer Para 9 for procedure to reset service
hour
9.4 Programming Solenoid Mode
For changing the solenoid mode first press (R) (reset) button, than press + button while
the reset button is pressed.
Fuel Solenoid: In this mode fuel solenoid contact changes from Open to Close at the
time of cranking and remains close till the engine is running. For stopping the generator
this contact opens.
Stop Solenoid: In this mode fuel solenoid contact remains open at the time of cranking
and till the genset is running. For stopping the engine this contact closes for a user
programmed time.
Don’t change the mode while engine is running. It’s a good practice to switch OFF and
than switch ON the battery supply after changing this mode.
10.0Faults
There are two categories of faults
Internal Faults
External faults
10.1 Internal Faults
Internal faults are the faults, which do not need any external signals and are detected by the system
itself. They are:
LLOP
Fuel
HWT
10.2 External Faults
Those faults which cannot be sensed by the unit itself (these faults are not reflected by the engine
directly) and are to be provided externally. They are:
RWL

Page 8/9
10.3 Fault Reset
All internal faults can be reset by pressing (R) switch after the generator is stopped. In case the
engine fails to stop “STOP KEY” can be pressed for manual attempt to stop engine.
