Earth (ground) fault AL44
N O T I C E
If an alarm has 2 states (warning/alarm), it only triggers a service log record when going into the alarm state.
5.15.8 15-2* Historic Log
View up to 50 logged data items via the array parameters in this parameter group. Data is logged every time an event occurs (not to
be confused with SLC events). Events in this context are defined as a change in 1 of the following areas:
Digital inputs
Digital outputs
Warning word
Alarm word
Status word
Control word
Extended status word
Events are logged with value and time stamp in ms. The time interval between 2 events depends on how often events occur (maxi-
mum once every scan time). Data logging is continuous, but if an alarm occurs, the log is saved and the values can be viewed on the
display. This feature is useful, for example when carrying out service following a trip. View the historic log contained in this parame-
ter via the serial communication port or via the display.
