When DIP switch S1.5 is at „ON", the maximum load voltage (with
U/U control) can be defined on potentiometer R201 TRAFO ADAPTI-

ON. The control characteristic curve is adapted in accordance with the
following equation: U
4.3.4 Setting maximum load current (only for...H RL1 and ...H RLP1)
The maximum load current is limited with potentiometer R203
CURRENT LIMIT, irrespective of the control mode. If there is no
I control, the potentiometer works as current limiter.
At reduced ambient temperatures, the power controller can only be
operated with up to 110% of its nominal current (effective value) (see
page 82, Technical Data).
