10.2 Error messages
Tip
To facilitate error diagnosis, the temperature controller emits 13voltage levels via the
analog output. In the temperature controller, the error messages are more precisely
differentiated and encoded as error codes.
The three-digit error codes can be displayed as follows:
• Temperature controller screen
• For information on the visualization software, refer to the manual for the visualiza-
tion software ROPEXvisual

.
Notes
In order to avoid incorrect evaluations, the evaluation of the analog output for the de-
tection of an error message – e.g. in the higher-level control unit – must be carried out
with an adapted tolerance window.
Comply with the analog output tolerances; refer to Technical data.
The following three tables show the assignment of the three-digit error codes to the
voltage level at the analog output. They also contain the causes and the measures re-
quired to remedy the error.
10.2.1 Part 1 of 3: Troubleshooting
The errors are reported as faults.
• The analog output emits constant voltage, the level of which is associated with a
set of error codes.
• Screen content
• Alarm relay is active.
