Equipment Manual, 09/2022, A5E51087503B AC
Cause
In the temperature measure‐
ment operating mode, an in‐
put voltage is too high. The
hardware may become dam‐
aged/destroyed as a result.
Reserved
Overload at the outputs
Incorrect operating mode se‐
lection, e.g. temperature
measurement at the analog
outputs.
Internal error, system error
Overrange at the inputs
Overrange at the outputs

Remedy
It is essential that a Pt100 el‐
ement is connected to termi‐
nals 3-4 or 7-8.
The module must be restar‐
ted with Power ON following
elimination of the error.
-
Check the loads at the analog
output.
The module must be restar‐
ted with Power ON following
elimination of the error.
If selected correctly, the mod‐
ule switches to cyclic opera‐
tion.
The firmware has detected a
system error, this status can
only be exited by means of a
switch-on / switch-off.
Check input circuit and ad‐
just, if required.
Correct the values in the user
program.
