LEDs are used for signalling. MWS Phase failure and sequence L1 L2 L3 100 % 0% 100 % L3 0% 100 % L2 0% Tr Tr Tr Tr 1 2 Operating principle MWS: 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 Va ), 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. 1 MWS : Relay R 2 Response time on appearance of a fault (Tr) 3 Mouser Electronics Authorized Distributor Click to View Pricing, Inventory, Delivery & Lifecycle Information: Crouzet: 84873029
