5 Settings
5.3 Subordinate control loop
Subordinate control loops are primarily used to eliminate or compensate for
external disturbances, such as fluctuations in the supply voltage and
alterations in resistance that have a negative effect on the operation of the
control loop.
Factory setting A subordinate U
2
control loop is factory set,
however, also the P or I
2
control loop is possible.

5.4 Load voltage adjustment
Switch S101-7 can be used to adjust the load voltage.
If the max. load voltage required is less than 75% of the
load voltage U
L Nom
as per type code, then S 101-7 must be opened.
If the maximum required load voltage is 75% or more of the nominal load
voltage U
L Nom
as per type code, then S 101-7 must be closed.
Factory setting S101-7 is closed.
