7 Function diagram MS220VA (automatic reset) MSR220VA (reclosing lock) Detector or line short-circuit Caution! The relay switches on automatically after a supply voltage dip. With a bridge at the reset input (Y1/Y2) the reclosing lock is out of operation. The device switches back automatically, when the temperature of the thermistor circuit has fallen below the switchback value. -

With commissioning and after modification of the plant the thermistor resistance must be checked with a suitable measuring instrument. With a resistance < 50 Ω the sensor circuit is to be examined for short-circuit. Attention! Check PTC’s only with measuring voltages of < 2.5 V.
