CMA User Manual
7.1 Error codes
When an internal error is detected by the valve, an Error
Code (J1939) or an Emergency Message (CANOpen) is
broadcasted from the system. For the J1939 version of
the system, the error is continually published until it is
acknowledged (refer to the Application Developers Guide).
CANOpen requires that an Emergency Message only be
published once per error detected. Each error detected is
also stored locally in each devices error log (on the valves
non volatile memory). The error is stored along with the
power cycle that correlates to when the error occurred.
The error log can be read by Pro-FX Configure or by a read
request to the valve. The error log will keep a maximum of
20 errors. Once 20 errors have been recorded, the log will
start to overwrite itself. The error log as well as the power
cycle count location in the object dictionary has
been summarized in Appendix B.
The following is a list of some of the possible error codes
that the valve will generate. The error codes have 4
different levels. The “Information” level message is just
that, informative and in most cases the user does not
need to worry. “Warning” messages should be able to
be addressed by the user. Messages that are “Critical”
or are an “Error” will require service by a qualified
service representative. Refer to the Service Manual for
recommended actions to take based on the each error.
