Stop!
The module will be destroyed if the connected signals or encoders
do not match the set measuring range:
l Max. 15 V input voltage in the voltage measuring range.
l No input voltage in the resistance measuring range.
l When the measuring range is changed, only assign the inputs
after the first gateway initialisation has been completed:
– During initialisation, the previous settings are still active.
Unsuitable input circuits may destroy the modules. Changes
will only become effective and permanently saved after
initialisation.

l Short−circuit unused inputs (connect positive and negative terminals) or
deactivate them by setting parameters.
l The module does not provide any auxiliary supply for sensors / actuators.
For information on how to connect an auxiliary supply, please see the
documentation for the sensors / actuators.
