4 SETUP PROCEDURE
WARNING!: To protect the alternator, ‘De-excite’ the alternator as described by the
alternator manufacturer before commisioning the engine governor. Only re-enable the
alternator after successful governor comissioning.
WARNING!: LIVE PARTS exist within the AVR. To avoid damage to persons and/or
property, only qualified personnel, having full understanding of the application must install the
product.
NOTE: For further details of module configuration, refer to DSE Publication: 057-271
DSEA108 Configuration Suite PC Software Manual.
The engine must be commissioned as far as possible before this procedure is carried out, in particular
the governor must be setup to produce stable speed control at 1500 RPM / 1800 RPM.
Use DSE Configuration Suite PC Software to upload the factory default configuration to the AVR if
required.

Page 18 of 58
Using DSE Configuration Suite PC
Software, select the appropriate Voltage
Set Point.
The Low Voltage Range (for 90 V to 300
V systems) or High Voltage Range (for
180 V to 600 V systems).
This voltage refers to the voltage applied
to the AVR
Land N (L2) terminals (the sensing
voltage).
Now select the Set Point menu and ‘uncheck’
the Preset Enable option.
This allows the Set Point parameter to be
configured.
Leave the Droop and External Bias settings in their default states initially, these are to be addressed
later.
Using DSE Configuration Suite PC
Software, select the appropriate
Frequency Range (50 Hz or 60 Hz).
Uncheck the Preset Enable option.
This allows Under Frequency Roll
Off Knee Point to be adjusted if
required.
To ease setup, adjust Knee Point to
a low value to prevent Under
Frequency Roll Off from activating
during the setup procedure.
Set the Under Frequency Trip Point
as required.
‘Uncheck’ Preset

and configure the
Set Point.
‘Uncheck’ Preset

configure
the Knee
Point

Setup Procedure
Page 19 of 58
057-281 ISSUE: 1
Open the selected Stability Configuration page.
Ensure the Proportional and Integral Preset Enable
options are checked, and set the Preset Range of both
to 100 %.
Set the Derivative Set Point to 0.
Set the Maximum Duty Cycle to 100 %. Leave all other
Excitation Output values at default.
Leave the Soft Start values at default for the first start. If
an excessive voltage spike occurs on start up, reduce
the Ramp Start Point.
Choose the Protections tab and set
Start-up Fail Delay to its maximum
value. This prevents it interfering with
the setup process.
Preset Enable
remains ‘checked’
Preset Enable
remains ‘checked’

Setup Procedure
057-281 ISSUE: 1
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.
