| BV1 - Phase sequence relay Application Supervision of phase loss, phase sequence and undervoltage in three-phase systems. Function Relay BV1 measures amplitude and angle of three phase voltages. The angle of the phasors determine the phase sequence. Unbalance and phase loss are detected by the measurement of amplitude and angle. www..com The undervoltage trip setting is 70 % of Un fixed. The underfrequency element trips if the frequency falls below 45 Hz. Technical data rated voltage Un: frequency range: hysteresis: power consumption: thermal load carrying capacity: returning time: minimum operating time: 110 V, 230 V, 400 V AC 45 - 66 Hz 2% Un 3 VA (4 VA BA1-400) continuously 1,3 x Un 700 ms 700 ms Fig. 1: Front plate Output relays: max. breaking capacity ohmic: 250 V AC/120 W DC inductive: 500 V AC/75 W DC rated current: 5A making current (16ms): 20 A System data: regulations: VDE 0435 Teil 303 temperature range at storage and operation: - 25C bis + 70C Mechanical stress: shock: class 1 acc. to DIN IEC 255-21-2 vibration: class 1 acc. to DIN IEC 255-21-1 degree of protection: weight: mounting position: IP 40 at closed front cover approx. 0,5 kg any The unit BV1 is designed to be fastened onto a DINrail acc. to DIN EN 50022 same as all units of the BASIC LINE. The front plate of the unit is protected with a sealable transparent cover (IP40). Please remove the transparent cover with a screw driver to adjust the relay. LED LED is used to indicate operation without fault with steady light. At tripping or underfrequency the LED extinguishes. 110 65 Fig. 2: Dimensional drawing of BV1 TB BV1 03.97 E 75 1 Auxiliary voltage supply The unit BV1 needs no separate auxiliary voltage supply. The supply voltage can be formed directly from the measuring quantity. Unit dead, wrong phase sequence or tripped Operation without a fault Fig. 4: Contact positions www..com Fig. 3: Connection diagram Connection terminals The connection up to a maximum of 2 x 2,5 mm cross-section conductors is possible. For this procedure the transparent cover of the unit has to be removed.
