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.
