CM42-MAA101EBE00 Diagnostics, troubleshooting
Endress+Hauser 23
Example
The device displays diagnostic message 011 "Sensor no communication". You want to change
this message so that no error is shown on the display, for example.
1. Go to SETUP/Sensor pH/ORP/Sensor diagnostics/Diagnostics list or SETUP/General
settings/Device diagnostics/Diagnostics list
The list of all the diagnostic messages is displayed. Here it does not matter which of the
two paths you used to open the list. The list is the same either way.
2. Select diagnostic message 011 and press the navigator button.
The details on the diagnostic message and the current message category are displayed.
3. Select the category and decide whether to change the category or deactivate the message.
4. Deactivate the message, for example (Disabled) and press "OK" to confirm your change.
The message without the letter of the Namur category is displayed in the diagnostic list.
The message is deactivated.
Proceed in a similar fashion if you want to change the category. You then see the change directly
in the list.
3.5 Pending diagnostic messages
The Diagnostics menu contains all the information on the device status.
Furthermore, various service functions are available.
The following messages are directly displayed every time you enter the menu:
• "Most important msg."
Diagnostic message recorded with the highest (most critical) Namur category
• "Past message"
Diagnostic message whose cause was the most recent to be remedied.
3.6 Diagnostic list
All the diagnostic messages currently pending are listed under DIAG/Errors / Messages.
The Namur category along with the number of the diagnostic message and a message
description are displayed.
3.7 Logbooks
The logbook memories are "ring memories". They are filled with data while storage space is
available. As soon as the memory is full, each new entry overwrites the oldest entry in the
memory.
To ensure data are recorded in the logbooks, you must activate the function in the
SETUP/General settings/Logbooks menu.
Logbooks cannot be saved to external memories or transferred to other transmitters.
The logbook entries are in chronological order. The most recent entry always appears at the top
of the list.
