Stephill SSD6000 - Low;High Frequency Shutdowns; Low;High AC Voltage Shutdowns; DSE 3110 Specific Faults and Battery Issues

SSD6000-SSD6000S-SE6000D4
22
● Check that all the green plugs are fitted
correctly and the wiring.
The no-load frequency/rpm should measure approximately 52.5Hz/3150rpm
Fault Icon
Possible Cause
Check
Emergency Stop Button
● Check if the emergency stop button has been
activated.
● Check the switches function and wiring on
the back of the emergency stop.
Emergency Stop
DSE 3110 Control Module
Fuel Lift Pump (12V DC)
● Check the fuel pump is receiving 12V DC and
is operating - Replace if necessary.
Contaminated Fuel
● If possible run the generator from a separate
fuel source from the fuel tank.
The DSE 3110 is displaying the correct no-load frequency (approx. 52.5Hz) but the
generator shuts down with the Low AC Voltage shutdown icon is displayed only.
Fuel Filter
● Check in-line fuel filter and replace if
necessary.
Fuel Tap
● Check the fuel tap is in the correct position -
On feed hose from the fuel tank.
Air Filter
● Check the condition of the air filter - Replace
if necessary.
Low
Hz/Frequency
Shutdown
Capacitor
● Test and/or replace the AC alternator
capacitor.
Main AC Alternator
● AC alternator tests would be advisable.
The no-load frequency/rpm should measure approximately 52.5Hz/3150rpm
Shutdown
Low AC Voltage
Low AC Voltage and Low Hz/Frequency could indicate the engine is running too fast.
Warning - It is not recommended to adjust the engine speed unless absolutely
necessary.
High
Hz/Frequency
Fail To Stop
Shutdown
The DSE 3110 is displaying the correct no-load frequency (approx. 52.5Hz) but the
generator shuts down with the High AC Voltage shutdown icon is displayed only.
Capacitor
● Check the correct size capacitor is fitted to
the AC alternator.
Automatic Voltage Regulator
(not a standard option - if applicable)
● Replace the AVR
Shutdown
High AC Voltage
Oil Pressure Switch
● Check the oil pressure switch operation -
Switch normally closed when engine is at rest
and open when engine running - Remove,
clean or replace if necessary.
Faulty Wiring
● Check associated wiring from the oil pressure
switch to the DSE 3110.
Service
● Oil change and oil filter clean recommended.
Low AC Voltage and Low Hz/Frequency could indicate the engine is running too
slow. Warning - It is not recommended to adjust the engine speed unless absolutely
necessary.
If none of the above solve the issue then a closer inspection of the engine would be
advised e.g. check that no-one has adjusted the engine speed, replace an injector etc.
