Adapting the analog inputs and outputs
If the setting ranges of the analog inputs and outputs are to be changed, the associated
interface converters (U401 / U402 / U403) must be set. The corresponding interface
converter must be removed for this purpose and the rotary switch on the side ("S1") turned
to the corresponding position.
