WARNING: POTENTIAL EQUIPMENT DAMAGE
The 120/240V three phase position has a wild leg that produces 208V
line to neutral on G2. Be sure when connecting to your panel or load,
that you match the wild phase on the generator to the wild phase in
your panel or load. failure to do so will result in 120V devices receiving
208V. You must also match your rotation.
Before wiring and starting this unit, be sure you have the selector
switch set for the right voltage. You must depress the safety switch
below the selector switch to change the position of the voltage selector
switch. If the unit is running, depressing this switch will shutdown the
engine-generator set.
At the same time you are making the voltage selection, you must also
adjust the setting on the mainline circuit breaker to give the proper
breaker protection. If you have any doubts as to the voltage in your
area compare your incoming power or load name plates.
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 both main line circuit breakers.
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.
