It is possible to set two independent voltage levels and thus it is possible to set two independent voltage levels and monitor e.g. undervoltage and overvoltage independently. In normal state when voltage is within set levels, output relay is closed and red LED shines. In case voltage exceeds or falls below the set levels, output relay opens and red LED shines ( LED indicates faulty state – flashes when timing). In case supply voltage falls below 60 % Un (UOFF lower level)relay immediately opens without delay and faulty state is indicated by red LED.In case timing is in progress and faulty state is indicated, timing is immediately stopped.
