7.5 Maintenance events
Maintenance events
A maintenance event is generated every time a maintenance requirement is determined. The
MT LED lights up on the module.
Maintenance messages are assigned either to one input on a channel-speci󹪝c basis (HART error)
or to inputs as a module message a󹪜ecting all inputs.
Maintenance messages have no direct e󹪜ect on the function of the module or the analog value
acquisition. Maintenance events of the HART communication do not a󹪜ect the analog value
acquisition of the module.
Maintenance messages, their meaning and possible remedies
Maintenance
message
Error
code
Assignment Meaning / Cause Remedy
Error (000B) B
H
Module The F-module has detected an internal mal‐
function of the HART communication and
therefore shut down the HART communica‐
tion.
Possible cause:
Electromagnetic interference is too high.
• Eliminate the interference.
Removal and insertion of
the F-module or a POWER
OFF – POWER ON is then
required.
• If the error occurs again,
consider replacement.
Error (000C) C
H
Module The internal temperature of the F-module
leaves the permissible range. This condition
must be corrected within the repair time of
the module, otherwise a safety-related shut‐
down of the entire module occurs.
Possible causes:
• Ambient temperature is too high
• Operation of the F-module outside the
permissible speci󹪝cation
• External heating by adjacent modules
Operate the F-module within
the speci󹪝ed temperature
range. (see "Technical speci󹪝‐
cations" section)
After reducing the tempera‐
ture and returning to the speci‐
󹪝ed range, this maintenance
message is automatically reset.

ules and replace modules or
perform a 󹪝rmware upgrade.
