After maintenance of the device, reset the maximum
pointer.
Electronic motor overload protection function testing.
The entire control circuit is tested, including the
switching elements and the error signaling output.
If the device responds as intended, tripping on
overload occurs. This can immediately be reset by the
"Reset" function without a cooling time.
The logbook is a history memory in which events,
warnings and faults are shown with a real-time stamp
and stored in a list. The communication and HMI
device logbook are also displayed here.
The logbook can be stored on a micro SD card.
