 The input has a very high
measurement, check the
measuring circuit.
 With a selected input with a low
voltage signal, it is only connected
on one side or the input is open.
 Not all of the activated setpoints
are parameterised. Check if the
relevant parameter PN1, PN2,
PN100…PN130 are adjusted
correctly.

 Please contact the manufaturer if
errors of this kind occur.
The addressed digital input does not
react.
 Measure the current of the digital
input with a multimeter. It should
be between 1 mA and 3 mA.
Program numbers for the analog
output PN20…PN22 are not
 The analog output is an option of
this device type. If it is not
