DIGITAL VOLTAGE REGULATOR (DVR A3) MODULE - Continued
Startup Profile
The DVR operates under one of two operational profiles. When the DVR senses that the generator is starting to
produce voltage, the Startup profile is used. When the output frequency has increased above the knee frequency
(programmable), the DVR will switch over to the Loading and Stopping profile.
In the Startup Profile (Figure 11) the DVR will follow a 1:1 V/Hz profile after generator frequency (engine speed)
has increased above the under frequency point (parameter: 10). This profile continues until the frequency reaches
the knee frequency (parameter :06). Once the knee frequency has been reached, the generator will be regulated
by the DVR to produce full rated voltage, as set by parameter :01. The DVR then switches to the loading and
stopping profile.
