measures for the individual diagnostic messages of the SM 336; F-AI 6 x 0/4 ... 20 mA
HART.
Table 9- 25 Diagnostic messages and associated corrective measures for SM 336; F-AI 6 x 0/4 ... 20 mA HART
Diagnostic message
Possible causes of the problem
Corrective measures
Module supply voltage L+ missing
Connect supply voltage L+
No external auxiliary voltage
Internal fuse defect
Module must be sent in.
Faulty parameters transferred to module Assign new module parameters
F_destination_address incorrect
Check the address switch (DIP switch)
CRC signature error during
communication between the F-CPU and
the module occurred, e.g., due to
electromagnetic interference in excess of
limits or sign-of-life monitoring error
Eliminate the interference
Assigned monitoring time exceeded
Check the monitoring time parameters
Parameter assignment
missing/incorrect parameters in the
module
Startup of the fail-safe signal module
—
Excessive electromagnetic interference
at times
Eliminate the interference, and
Switch the supply voltage of the F-
CPU/IM OFF/ON,
Remove/insert F-SM, or
Switch external auxiliary voltage of F-
SM OFF/ON
Firmware update cancelation due to error If the error has gone out, repeat the
firmware update.
Time monitoring activated
(watchdog)
Defective module
Replace the module
Defective module
Replace the module
Internal supply voltage of the
module failed
Excessive electromagnetic interference
at times
Eliminate the interference, and
Switch the supply voltage of the F-
CPU/IM OFF/ON,
Remove/insert F-SM, or
Switch external auxiliary voltage of F-
SM OFF/ON
Electromagnetic interference has
exceeded limits
Eliminate the interference, and
Switch the supply voltage of the F-
CPU/IM OFF/ON,
Remove/insert F-SM, or
Switch external auxiliary voltage of F-
SM OFF/ON
Defective module
Replace the module
Ambient temperature too high
Check installation conditions, and
Switch the supply voltage of the F-
CPU/IM OFF/ON,
Remove/insert F-SM, or
Switch external auxiliary voltage of F-
SM OFF/ON
Processor failure
Switching rate exceeded
Reduce switching rate
