7.3 PQF-Manager overview and navigation
All user inter-action with the filter is channeled through the PQF-Manager. It provides for
the following main functions (Cf. Figure 69):
− Filter starting, filter stopping and acknowledgement of faults
− Selection of power module for which the relevant data is displayed
− Measuring, analyzing, logging
− Setting up the filter
− Monitoring the filter load, event logging and status of individual units
− Providing filter identification information
Figure 71 outlines the principle menus that are accessible through the ‘Welcome’ screen.
In a multi master configuration (several master units in parallel in a single filter), the
PQF-Manager on the “Master” unit has all the menus and options active. The PQF-
Manager(s) on the “Slave” unit(s) have different screens in the sense that certain items
(menu, buttons etc.) are “non-active” and may appear “greyed”. In case the maser unit
fails and the next unit in the order takes over as new master (due to redundancy
feature of PQF), the menu of the new master automatically adapts to this new
situation.
