WARNING
• Check signal LEDs "red"
• Eliminate the cause in the indicated
field circuit, check electric lines and
field devices
• Change configuration in the
automation system or connect the
correct module
• Check the cyclic data transfer of CPM
or CPU (LCD or LED "RUN")
• Check bus connection
• Activate the cyclic data transfer with
the automation system
• Replace the module
• Reduce ambient temperature, for ex-
ample by means of shading or cooling
Note: If the problem is not eliminated,
the module will be permanently
damaged
• Replace the module as soon as
possible within the next 12 months,
otherwise, there is a risk of module
failure
• Eliminate the cause in the indicated
field circuit, check electric lines and
field device
• Repeat compensation
