Stephill Generators SSDP30-70 - DSE 6110 Fault Finding Guide
Issue 3
Failed to Start
- Shutdown
The module will display
Failed to Start
after 3 attempts to start.
This shutdown is issued if the AC frequency measured on the DSE 6110 MK3 hasn’t reached the desired level - Fig.2.
c) Check the connections on both sides of the fuse holders.

Shutdown
c) Check the connections on both sides of the fuse holders.
Important Note
If the above has not highlighted the fault condition, then a closer look at the main alternator would be the next step.
Gen Under Frequency/Hz
-
Shutdown
The module detected that the generator output voltage on one or more phases has fallen below
a pre-set level - Fig.3.
d) Remove the main alternator control box lid and check all connections on the main windings. Check for broken,
lose or burnt wiring.
b) Check the three fuses on the back of the control panel that have a Brown, Black and Grey wire terminated. A
spare fuse can be found in the fuse holder.
a) Check the AC plug in the back of the DSE 6110 control module is firmly inserted. This is the green plug with a
Brown. Black, Grey and Blue wires.
Navigate to the
Generator Voltage
screen on the DSE 6110 module (user guide - page 4). Start the generator and check
that all the voltages displayed are correct. If there is an large imbalance of voltages then check the following;

d) Remove the main alternator control box lid and check all connections on the main windings and AVR
(Automatic Voltage Regulator). Check for broken, lose or burnt wiring.
b) Check the three fuses on the back of the control panel that have a Brown, Black and Grey wire terminated. A
spare fuse can be found in the fuse holder.

screen on the DSE 6110 module (user guide - page 4). Start the generator and check
that all the voltages displayed are correct. If there is an large imbalance of voltages or no voltage then check the following;

Using the
Status
screen or the
Generator Frequency
screen, start the generator and monitor the frequency on the display -
Hz. Typically the no-load frequency should be between 52.0 and 53.0Hz.
