Time indicates the total number of operating hours
after which the trip occurred. Display range 0.0 -
999.9.
Value indicates e.g. at what voltage or current the trip
occurred. Display range 0.0 - 999.9.
Serial communication - the fault code is returned in
the form of a whole number. Time and value are
registered in the form of floating decimal point values.
8 log values are indicated (0-7).
The lowest log number (0) contains the most recent/
last data value saved, with the highest log number (7)
containing the earliest data value.
An alarm can only be represented once. The fault log
is reset after manual initialisation. Regardless of the
log set being studied at any given time, the display
automatically switches to log no. 0 if another trip
occurs.
