Action: the control device of AVR-01-S controls tension on two inputs of the three-phase alternating current main. If tension within norm, loading 1 is connected to input 1, loading 2 is connected to input 2 by means of the external switch (the contactor, the time cut-out with the motor drive, etc.) which is managed by the AVR-01-S final-control relay. At accident of one of inputs loading is connected to the second by a selectionalizing switch. At recovery of a power supply on input loading switches to it. A power supply of AVR-01-S is carried out from controlled inputs.

― to power off
― to establish AVR-01-S on a DIN rail, to connect according to the scheme of connection.
― to establish, tap wrenches on the front panel, required values of switching time and reclosing time of both inputs of a power supply.
― to include a power supply, indication will light up (A, B, C) both inputs, will join the K1 and K2 relay, the LEDs corresponding to them will light up.
― for work check to disconnect one of phases of input 1, the K1 relay (K1 LED will go out) should be switched-off, and through the determined time the K3 relay will turn on (K3 LED will light up).
― to recover the disconnected phase, the K3 relay (K3 LED will go out) should be switched-off and through the determined time the K1 relay will turn on (K1 LED will light up).
― for check of an emergency shutdown of inputs in turn to close S1-S3 switches, there will be shutdowns/turning on of the K1-K3 relay.
