*) The fuse monitoring equipment is generally connected to the armature current circuit, although it can also be used for
the field circuit, fan circuit, or the primary circuit of a heavy-current transformer. The connections used for fuse monitoring
depend on the voltage prevailing at a blown fuse.
**) This resistor is in parallel with the fuse. A bridge rectifier is connected in series to this resistor; this means that the
specified value cannot be correctly measured using a commercially available ohmmeter.
"Fuse monitoring" module
Switching fuse monitoring on/off via p51831 (0=OFF, 1=ON).
