Manual, 08/2018, A5E32350124-AD
Diagnostics alarms - for the measuring range: 0 V to 10 V and 4-DMU 0 mA to 20 mA
Error code
Meaning
1
Short-circuit encoder supply to
H
ground
7
Value is above overrange.
H
Value is below underrange.
H
9
Value is significantly above or
H
below underrange/overrange.
10
Module parameter assignment is
H
faulty
16
At least one hardware interrupt
H
could not be signaled because
too many hardware interrupts are
pending.

Remedy
Correct interplay between module
and encoder
Correct interplay between module
and sensor
Correct interplay between module
and sensor
Correct interplay between module
and sensor
Correct the parameter assign-
ment
Correct the program or the pro-
cess
Remedy
Use a different encoder type or
modify the wiring, for example,
using cables with larger cross-
section
Connect the cable
Deactivate diagnostics
•
Connect the channel
•
Deactivate channel

Correct interplay between mod-
ule and sensor
Correct the parameter assign-
ment
Correct the program or the pro-
cess
