Phase sequence monitoring
When all the phases are connected in the correct sequence and the
measured asymmetry is less than the fixed value, the output relays
switch into on-position (yellow LED illuminated). When the phase
sequence changes, the output relays switch into off-position (yellow LED
not illuminated).

Detection of reverse voltage (by means of evaluation of asymmetry)
The output relays switch into off-position (yellow LED not illuminated)
when the asymmetry between the phase voltages exceeds the fixed
value of the asymmetry. An asymmetry caused by the reverse voltage
of a consumer (e.g. a motor which continues to run on two phases only)
does not effect the disconnection.

Phase failure monitoring
When one of the three phases fails, the output relays switch into
off-position (yellow LED not illuminated).
