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.
Exceeding or undershooting of thresholds, that can be changed by the user himself
(see Section 7.1.3.3), is also displayed in the event log.
Faults in the power system are indicated with " Network Fault " and the present fault
number. The fault messages ( Trip Log ) contain details about the history of faults.
This topic is discussed in Sub-section 7.1.1.3.
Earth faults are indicated with „ Earth Fault " and numbered consecutively (only de-
vices provided with the earth fault detection function). Detailed information on earth
faults messages can be found in Subsection 7.1.1.4., Earth Fault Messages .
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).

at first. The applicable date and time are noted in the display line directly above the
message. If the memory for the operating messages is not full, then the end of the en-
tries is indicated by " END ".
