3. About the Battery Watch
The BW 801e battery watch is a two-stage safety system to avoid deep
discharge of your battery. Alarm functions warn you acoustically and visually
of imminent deep discharge. If power continues to be removed from the
battery, the battery watch disconnects consumers from the battery to
prevent deep discharge. The threshold values for the alarm and for switching
off the consumers are set via DIP switches.
