Setup Procedure

Page 20 of 58
Using DSE Configuration Suite PC
Software, connect SCADA and select
the Commissioning Screen display.
Set the
Proportional
preset on the AVR
to approximately 10. Set the
Integral
preset on the AVR between 1 and 2.
Ensure the derivative value is 0, and
the
Output Duty Cycle
is 100 % with the
engine not running.
Connect a voltmeter to the alternator
output, preferably connected ‘phase to
neutral’
NOTE: If an oscilloscope is not available, the voltmeter and SCADA screen are used
solely. This does not show rapid oscillation of the voltage output and hence does not provide
the optimum setup environment.
If available, connect an oscilloscope to the alternator output, preferably connected
‘phase to neutral’,
and set it to a slow time-base so that the spot takes about 4 seconds to traverse the screen. Set it to
‘auto-trigger’ so that it keeps rolling continuously. It is the variation in the peak voltage that is of
interest as it shows instability and settling time very clearly.
