20 log values (0-19) are given. The lowest
3 4 - - 19
number (0) contains the newest/last stored
data value, and the highest log number
(19) contains the oldest data value.
The data values are logged every 160 ms
for as long as the start signal is active.
The data log contains the last 20 log
values (approx. 3.2 s) before a stop signal
is given (start not active), or a trip.
However, it is possible to scroll through the
log values.
The data log is reset during start-up (on
mains connection).

Fault code indicates the reason for a trip by
a figure code between 1 and 15:
Fault code

Time states the value of the total number
of operatin hours on trip. Display range
0.0-999.9.
Value states e.g. at what voltage or current
a trip has taken place. Display range 0.0-
999.9.
On serial communication, the fault code is
returned as a whole number. Time and
value are returned as floating decimal
values.
8 log values are given (0-7). The lowest log
number (0) contains the newest/last stored
data value, and the highest log number (7)
contains the oldest data value.
An alarm can only be represented once.
The fault log is reset after manual initializa-
tion.
Irrespective of which log set is being read,
the display will automatically shift to log
number 0 if a new trip occurs.
