Event Log (Operating Messages)
Operating messages contain information that the device generates during operation
and about the operation. Up to 200 operating messages are stored in chronological
order in the device. New messages are added at the end of the list. If the memory has
been exceeded, then the oldest message is overwritten for each new message.
Faults in the power system are indicated with “
1HWZRUN)DXOW
” and the present fault
number. The fault messages (
7ULS/RJ
) contain details about the history of faults.
This topic is discussed in Sub-section 7.1.1.3.
All predefined operating messages are listed and explained in a table in the Appendix.
In a specific case, of course, only the appropriate messages appear in the display. The
appendix also shows whether the message is only issued as “ON” (to indicate an
event), or as “ON” and “OFF” (to designate the beginning and end of a condition).
