104 The PQF-Manager user interface Manual Power Quality Filter PQFS
PQF-Manager has six programmable digital output contacts. Each of them can be
programmed from a set of possible filter condition. If the selected condition is attained,
that specific output contact closes.
WARNING: If a function is assigned to a digital input, the same function must never be
assigned to the other digital input. Otherwise the filter may behave erratically.
For full redundancy with multi-master filters, these functions need to be set up in each
master unit of the filter system and the functions should be cabled accordingly.
7.9.2 The ‘Commissioning’ menu
WARNING: The commissioning menu is intended to be used by qualified
commissioning engineers that are authorized to change the filter’s core installation
settings and to set up the user’s requirements.
In multi-master units these functions need to be set up only in the master with the
lowest hardware ID setting.
The complete commissioning procedure must be executed each time a filter is (re)-
installed or when a unit is added to the existing filter. During the commissioning
procedure, the user settings will be lost, so note them down prior to starting the
commissioning procedure.
Refer to Section 7.6 for determining appropriate locking facilities for this menu.
For an overview of the main items of the commissioning window, refer to Figure 57.
These items are discussed next.
For commissioning the active filter follow the commissioning procedure presented in
Chapter 8.
