To allow for short term mains supply transient conditions
or false remote start signals, the start delay timer is
initiated. After the Fuel Solenoid is energised, then ¹/²
second later, the Starter Motor is engaged.
The engine is cranked for 10 seconds. If the engine fails
to fire during this cranking attempt than the starter motor
is disengaged for 10 seconds. Should this sequence continue
beyond the 3 cranking attempts, the start sequence will
be terminated and Fail to Start fault will be
displayed. When the engine fires, the starter motor is
disengaged and locked out.
Delayed alarms (under speed, low oil pressure etc) will
be monitored after the end of the Safety On Delay.
If the romote start is being used and has been configured
to Remote Start is on load, or the mains has failed, the
load will be transferred to the generator.
On the return of the mains supply, the Stop delay timer
is initiated, once it has timed out, the load is transferred
back to the mains (utility). The cooling timer is than
initiated, allowing the engine a cooling down period (180
sec) off load before shutting down. Once the cooling
timer expires the fuel solenoid is de-energised, bringing
the generator to a stop. Selecting STOP de-energises
the fuel solenoid, bringing the generator to a stop.
7.3.3 Test Mode of Operation
This mode is activated by pressing the pushbutton.
A LED indicator beside the button confirms this action.
Press the button to begin the test sequence.
After the Fuel Solenoid is energised, then ¹/² second later,
the Starter Motor is engaged.
The engine is cranked for 10 seconds. If the engine fails
to fire during this cranking attempt then the starter motor
is disengaged for 10 seconds. Should this sequence continue
beyond the 3 cranking attempts, the start sequence will
be terminated and Fail to Start fault will be displayed.
When the engine fires, the starter motor is disengaged
and locked out.
Delayed alarms (under speed, low oil pressure etc) will
be monitored after the end of the Safety On Delay. The
load will be transferred to the generator and the set will
run on load untill Auto mode is selected or Stop is pressed.
Selecting Stop de-energises the fuel solenoid, bringing
the generator to a stop.

AUTOMATIC CONTROL PANEL
The DSE 720 automatic mains failure controls
generating set system. Module has been designed
to monitor the mains (utility) supply.
7.3.1 Manual Operation
•
This mode is activated by pressing the
pushbutton.
A LED indicator beside the button confirms this
action. Press the button to begin the start
sequence (There is no Start Delay in this mode of
operation)
After the Fuel Solenoid is energised, then the Starter
Motor is is engaged.
The engine is cranked for 10 sec. If the engine fails
to fire during this cranking attempt then the starter
motor is disengaged for 10 sec. If the engine fails to
fire during this cranking attempt then the starter
motor is disengaged for 10 sec. Should this sequence
continue beyond the 3 cranking attempts, the start
sequence will be terminated and Fail to Start
fault will be displayed.
When the engine fires, the starter motor is
disengaged and locked out.
Delayed alarms (under speed, low oil pressure etc)
will be monitored after the end of the Safety On delay.
The generator will run off load unless the mains
supply fails.
The generator will continue to run on load regardless
of the state of the mains supply.
If auto mode is selected, and the mains supply is
healthy then the Remote Stop Delay Timer begins,
after which, the load is transferred to the mains.
The generator will then run off load allowing the
engine a cooling down period.
Selecting stop de-energises the fuel solenoid,
bringing the generator to a stop.
7.3.2 Automatic Mode Of Operation
This mode is activated by pressing the pushbutton.
An LED indicator beside the button confirms this action.
Should the mains (utility) supply fall outside the
configurable limits for longer than the period of the
delay start timer, the mains is healthy indicator will
estinguish. Additionaly, while in AUTO mode, the remote
start input is monitored.
Whether the start sequence is initiated by mains failure,
or by remote start input, the following sequence is
followed:
