Setup Procedure

057-295 ISSUE: 1
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.
