6.13.5 Cabling of main/auxiliary control functionality
The active inverter features main and auxiliary control setup modes. This implies that
two different compensation characteristics can be defined, e.g. one for the day and one
for the night or one for normal network operation and one for backup generator
operation. With the ESI-Manager a set up can be made to either use always the main or
the auxiliary settings. In addition, the possibility exists to switch between main and
auxiliary settings 'automatically' according to a signal applied to a digital input of the
ESI-Manager (Cf.
factor for switching between the main and auxiliary settings. Moreover, both normal and
inverse logic can be used to drive the digital inputs.
The electrical requirements of the digital inputs are as discussed in
Figure 45
gives an example of how to implement the main/auxiliary control switching
functionality on Digital Input 2. It is assumed that normal control logic is used.
