COMMUNICATION
NOTE: For further details of module configuration, refer to DSE Publication: 057-271
DSEA106 MKII Configuration Suite PC Software Manual.
Caution: Do not disconnect the USB from DSE815 whilst it is connected to the AVR. Doing
so results in loss of voltage control and potential damage to the generator.
WARNING! As the AVR is isolated from ground it is possible that the configuration is live
during operation.
In conjunction with the DSE815 Configuration Interface, the communication port is provided to give a
simple means of connection between a PC and the controller.
Using the DSE Configuration Suite Software, the operator is then able to monitor the device and
perform reset operations.
Additionally, the various operating parameters are available to be viewed or changed.
To connect a module to a PC by USB, the following items are required:
•DSEA106 MKII
•DSE815 Configuration Interface
•DSE Configuration Suite PC Software (available from www.deepseaplc.com).

Page 18 of 48
4 SETUP PROCEDURE
CAUTION: 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. When powered avoid contact with
components and terminals. To avoid damage to persons and/or property, only qualified
personnel, having full understanding of the application must install the product.
CAUTION: Do not disconnect the USB from DSE815 whilst it is connected to the AVR.
Doing so results in loss of voltage control and potential damage to the generator.
NOTE: For further details of module configuration, refer to DSE Publication: 057-271
DSEA106 MKII 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.
AVR INITIAL SETTINGS
Determine from the alternator sensing connections what level of voltage feedback the AVR receives
from the alternator.
Set the AVR DIP Switches as required to match the AVR sensing voltage and frequency. This setting
must be suitable from the voltage applied across the L1 and N (L2) terminals.

Setup Procedure
Page 19 of 48
057-269 ISSUE: 4
Using DSE Configuration Suite PC Software, select the
appropriate voltage menu 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,
ensure that the Auto Frequency Detection is
disabled and select the appropriate frequency
menu (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 and Idle
Frequency Detection as required.
‘Uncheck’ Preset

the Knee Point

Setup Procedure

Page 20 of 48
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
Delayto its maximum value. This prevents it
interfering with the setup process.
