DSE4510 INITIAL START UP
WARNING: 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.
STARTING PROCEDURE
MANUAL MODE
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.
1. Press and release the red Stop/Reset button
2. Press and release the green Start Engine button. The engine-
generator set will crank and start automatically. If the engine fails
to start, it will display a fault code and the common alarm
indicator will start blinking. See the fault code appendix portion of
this
manual.
3. With the unit running smoothly, check the no load voltage and
frequency of the generator output.
4. Once the unit is running and the safety on time has elapsed, the
engine monitoring switches are active for low oil pressure and
high water temperature.
5. After the engine is up and running, the circuit breaker can be
closed to power your loads. During periods of very cold operation,
it is best to let the engine warm up for a few minutes before
applying the load.
6. When stopping the unit, it is best to turn off all the loads before
pressing the stop button. This prevents your loads from getting
low voltage while still running during shutdown.
