The AC units are adjusted to the r.m.s value. They have settingsfor response value and hysteresis. The units work as overcurrent relays butcan also be used for undercurrent detection. The hysteresis is dependenton the response value.2 time delays are possible in different variants:The start up delay ta operates only when connecting the auxiliary supply.It disables tripping e.g. caused by an increased starting current of amotor. The response delay t v is active after exceeding a response value.On overcurrent relays the delay is active when the current goes over thetripping value, on undercurrent relays when the current drops below thehysteresis value.IndicatorsAll technical data in this list relate to the state at the moment of edition. We reserve the rightfor technical improvements and changes at any time.Green LED:On, when auxiliary supply connectedYellow LED:On, when output relay acitvated121.04.21 en / 387A
