4.12.3.2 USING THE ALTERNATIVE CONFIGURATION TO HANDLE SPEED CHANGE
This shows how to use the default configuration to handle automatic speed change of a CAN engine. The
same process is also used to select different configurations for other purposes.
The ‘main configuration’ is set to suit
a 50Hz generator. The engine is a
1500RPM Volvo TAD9 with EMS2b
ECU.
The alternative configure has been
enabled,
And the alternative engine speed
has been selected. When this
configuration is activated, the engine
will be instructed to run at its
configured alternative speed. For a
1500RPM engine, the alternative
speed will be 1800RPM.
As the engine will be running at a
higher speed, we also need to
select appropriate settings for the
speed and frequency trip points in
the alternative configuration.
Selecting between the main and alternative configurations is achieved using either:
• Configuration Suite Software (Selection for ‘Default Configuration)
• DSE8810 module Fascia Editor
• Via external signal to DSE8810 module input configured to “Alt Config x” select.
• Auto Voltage Sensing. Whereby during the starting sequence, the AC system, voltage and frequency
of the connected supply is monitored. The module selects the most appropriate configuration
(alternative 1, 2 or 3 or the main configuration) to suit the connected supply.
