When all the phases are connected in the correct sequence
and the measured asymmetry is less than the set value, the
output relay R switches into on-position.
Phase sequence monitoring
When the phase sequence changes, the output relay R swit-
ches into o-position.
Phase failure monitoring
When one of the three phases fails, the output relay R switches
into o-position.
Asymmetry monitoring
When the asymmetry exceeds the value at the ASYM-regulator,
the output relay R switches into o-position. Reverse voltages
of a consumer (e.g. a motor which continues to run on two
phases only) do not eect the disconnection.
