Termination of not used inputs
Figure 6: Resistor circuit for the inputs
Note Not used inputs, which are connected in the HIMA function block HB-
RTE-3, must be terminated with a 10 k
Ω resistor at the input of the
module. Thereby line error messages of the not used input channels
are eliminated (see following scheme).
