The Powerwizard Integrated Voltage Regulator (IVR) feature is a substitute for a traditional voltage regulator configuration. The traditional voltage regulator configuration consisted of a dedicated controller such as an R450M/T.
The Powerwizard internal controller regulates generator output voltage. The voltage is regulated by sending a command to the excitation module (EM10/EM15). The excitation module controls generator excitation and therefore generator output voltage.
The IVR feature is available with revised Powerwizard 1.1+ and 2.1 controllers with software version 4.3 PROD and above. The capability does not exist in original Powerwizard 1.1+ and 2.1 controllers regardless of software version.
The IVR parameters can be accessed using either the Perkins EST Service Tool, or directly through the Powerwizard display. Some set points are locked using Perkins EST Service Tool only or at security level 3. The set points that are locked will require a level 3 password. Perkins Service Tool version 2016 or later is needed to access and adjust the IVR parameters.
To access the IVR set points using Perkins EST Service Tool, connect to the Powerwizard generator set control. Click on the "Configuration Tool" button or as an alternative press "F5" to enter the configuration menu. Select "Integrated Voltage Regulator" from the menu on the left. Set voltage regulator control source configuration equal to "generator set control" to display the following default settings.
50 Hz Note:
Currently all 50 Hz rated 1506, 2206, 2506 and 2806 powered generating sets fitted with an IVR are set to a knee frequency of 48 Hz, this can be adjusted up to 49.8 Hz depending on the application and speed of recovery.
