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 relay 
switches into on-position (yellow LED illuminated). When the phase 
sequence changes, the output relay switches into off-position (yellow 
LED not illuminated).

Phase failure monitoring
The output relay switches into off-position (yellow LED not illuminated), 
when one of the three phases fails.

Asymmetry monitoring
The output relay R switches into off-position (yellow LED not illuminated) 
when the asymmetrie exceeds the value set at the ASYM-regulator.
Reverse voltages of a consumer (e.g. a motor which continues to run on 
two phases only) do not effect the disconnection.
