Operating principle
MWS-MWS2 : Phase controller
The relay monitors its own supply voltage.
The relay controls :
- correct sequencing of the three phases,
- total failure of one of the three phases.
When the phase sequence and voltages are correct (> 183 VAC), the output relay (s) are closed and the yellow LED is lit.
In the event of a phase sequence or total phase failure fault (detected when one of the voltages drops below 100 V), the relay opens instantly and its LED is extinguished.
When the unit is powered up with a measured fault, the relay stays open.
