This generator is equipped with a shunt trip circuit breaker
that is interrupted by the DSE7310 controller if current limits
are exceeded. These limites are adjusted based upon the
nominal voltage of the current swithc position.
INITIAL START UP
WARNING: EQUIPMENT DAMAGE
Before attempting to start this unit, complete
your pre-start checklist and ensure the generator
mainline circuit breaker is in the proper position
prior to starting. Starting this unit without it properly
connected can cause serious personal injury or
equipment damage.
DO NOT jump start these engine-generator sets. Starting
these units on a low battery or jump starting them will
cause damage to the engine control module.
Use the following check list to verify correct installation
before starting the engine.
□
Engine oil. Fill as required with proper grade/qty.
□
Engine coolant. Fill as required with proper mixture.
□
Unit mounting base properly bolted down.
□
Clearance for service and maintenance on all sides.
□
Proper fuel line material and size.
□
All fuel line connections tight.
□
Battery connections clean and tight
□
Battery fully charged.
□
All AC and DC wiring installed and properly
protected.
After completing the previous checklist, the engine-
generator set is ready for initial start-up.
MANUAL MODE
1. Select the desired voltage with the selector switch.
2. Turn off the main line circuit breaker.
3. Press and release the MANUAL MODE button. The small
LED light next to it should come on.
4.. Press and release the green START ENGINE button. The
DSE 7310 MKII will send a start signal to the glow plug
solenoid on the engine. Preheating the engine for about
10 seconds at the end of that time will engage the fuel rack
solenoid and the starter. This will start the cranking cycle
(10 seconds on and 10 seconds off).
Note: There is no start delay in this mode of operation.
If the engine fails to start during this cranking period, the
starter motor is disengaged and goes into a rest mode after
which a second attempt is made to start the engine. Should
this sequence continue through 3 cranking cycles the start
sequence will be stopped and the display will show ‘FAILED
TO START”.
All engine functions are controlled by the DSE 7310 MKII
controller. Once the unit is running, the control will display
the engine information, To get the generator information,
scroll down on the controller.
The AC ouptut readings displayed on the DSE 7310 MKII
are collected through the AC interface harness wired in
the generator control box. Any shutdowns related to the
AC output are a function of the controller are based on
information collected in the DSE 7310 MKII via this AC
harness.
5. After the engine is running at the proper speed, adjust
the voltage to the desired level using the external voltage
trim rheostat.
6. Turn on the proper main line breaker (either high or low
voltage) and padlock the lock bar to prevent the incorrect
breaker from being turned on.
WARNING: EQUIPMENT DAMAGE:
Never apply a load to the generator until you have
first checked the voltage at the terminal blocks or Cam-
Locks.
7. With the engine running smoothly check the no load
voltage and frequency on the digital display. The voltage
should be 208/240/480 AC depending on which model
you have and a frequency of 59.5 to 60.5 hertz (Hz).
If you have the proper voltage at the generator the next
step is to check the voltage at the generator terminals. The
voltage between the L1, L2, and L3 terminals should be the
same as it was on the generator front panel. The voltage
should also be checked between the hot terminals (L1,
L2, and L3) and the N to be certain of a balanced voltage
output and a solid neutral connection.
ON 240 VOLT (DELTA) SYSTEMS BE SURE YOU KNOW
WHERE THE HIGH VOLTAGE “WILD” LEG IS. IT MUST BE IN
THE SAME LOCATION ON THE LINE SIDE AS IT IS ON THE
GENERATOR SIDE.
NOTICE
If for any reason during the check out procedure the
voltage and frequency are not correct, depress the
STOP/RESET button and correct the trouble before
proceeding.
8. Stopping - In manual mode, pressing the STOP/RESET
button will stop the unit but only after the cool down timers
have timed out and there is no remote start signal being
sent to the unit. Pressing the STOP/RESET button a second
time will shut down immediately.
In the event of an emergency, the E-Stop can be pushed.
WARNING: EQUIPMENT DAMAGE
Stopping the generator without sufficient cool-down
time, can result in premature wear and cause damage
to engine components. The EStop and override
shutdowns should only be used in the event of an
emergency.
AUTO MODE
To activate the automatic start mode you will just need to
depress the AUTO button, the LED indicator beside the
button confirms that the unit is in automatic mode.
