5.13 Adjusting the output level signal (output adjust U

, P , I

)
In the factory settings, the output level signal corresponds to the I
2
signal at
the output of the converter. It is thus proportional to the power in the load
(R=constant).
However, setting P or U
2
instead of the I
2
signals is also possible

The output level signal provides a voltage in the range of 0 to 10V
(corresponding to 0 to 100% of the variable being measured). The trimmer

end value:
5.14 Process dependent load reduction
Switch S101-10 can be used to activate the process dependent load
reduction. The load is reduced depending on the resistance value R when
operating Molybdenum Disilicide heating elements. When the converter is
operating within rated limited, the load reduction amounts to approx. 10 %.
This must be taken into consideration when the converter operates outside its
rated limits (nominal voltage and current).
