Readout of the monitoring
signal memory
If the unit detects an internal fault in the course of internal self-monitoring routines or if it
detects power system conditions that prevent flawless functioning of the unit, then an
entry is made in the monitoring signal memory. A maximum of 30 entries is possible.
After that an ‘overflow’ signal is issued.
