PURPOSE OF THE RELAY
 The phase selection relay RVF-01, RVF-02 (phase commutator, phase switch) a single-phase unit of automatic transfer switch (further - AVR) is connected, tupically, to three phase main and provides for switching single-phase consumers at power phase optimal at level of voltage at oscillations or a complete failures of the supply voltage "operating" phase. AVR provides constant monitoring of the quality and availability and quality of voltage on the phases, in dependence on parameters, automatically selects the most optimal phase and high speed switches a power to the single-phase load to this phase. When switching from phase to phase, to exclude interphase closures, AVR checks off the alarm phase, and only afterwards includes reserve.
 In the case of sticking of contacts relay or contactor, AVR does not switch to a different phase, even at the output of a voltage in this phase of the set limits (from circuit protection between phases).
 RVF-01 - without function of control state external contactors (winding break, contacts burning, etc)
 RVF-02 - with function of control state external contactors (winding break, contacts burning and etc)
 AVR can operate with 2 or 3 independent sources of single-phase voltage, frequency from 45 to 65Hz. Can be used in a single-phase net, and as an additional phase - electrogenerator.
 It is used in nets with unstable voltage for supply security and fire alarm systems, video surveillance, unauthorized access, industrial and technological, and other single-phase equipment with a continuous cycle operation.
 There is the option to return to the priority phase after switching to reserve, i.e. return power of the load from the priority phase after recovery a voltage.
 
DESIGN OF THE RELAY
 Relay is produced in a unified plastic case with front connection wires power and switched circuits. Mounting is carried out on a DIN rail  width 35mm (GOST R IEC 60715-2003) or on a smooth surface. To set on a smooth surface, spring locks must be changed in recent holes, fixing a spring lock, which are located on the back side of the case. Terminal design provides robust clamp wires up to 2,5mm2. On the front panel there are: 3 green indicators of availability voltage of phase "A1", "A2" and "A3", 3 yellow indicators of actuation built-in executive relay "B1", "B2" and "B3", regulator of turning on relay "ton",  regulator of return time "treturn", regulator of threshold actuation undervoltage "Umin".
 
OPERATION OF THE RELAY
 AVR has three independent inputs, terminals "A1" (priority phase) and "A2", "A3" (reserve phase) and output terminals "B1", "B2", "B3" accordingly to connect the load. Terminal «N» to connect the neutral wire, terminal «Y1» designed for controlling the state of switching relay contacts or additional contactors required to increase the load capacity. AVR allows to connect load up to 16A (3,5kW) directly to the device. When power exceeding 3,5kW (16A) AVR controls single-phase coils of magnetic contactors of appropriate power.
 When powering AVR checks the voltage on the priority phase, and if all the parameters are within acceptable values, connects the load through a predetermined by user delay on the enabling. If the value of the priority phase voltage does not comply with parameters, AVR checks the reserve phase and connects the load through it. When restoring the power supply voltage on the priority phase, AVR switches to it load, through a user-defined return time.
 
Recommendations:
 If AVR switches a large load capacity, it is recommended to include priority mode, which allows, after recovering the mains parameters, return to the priority phase. This avoids overloading reserve phase.
 In all other cases, the priority function is not required.
 In the absence of the circuit contactors, terminal «Y1» not necessary to use (only for the relay RVF-01).
  When connecting external contactors must be selected relay RVF-02 and use «Y1» terminal to monitor the state of switching devices.
 It is recommended to use the delay of actuation time during short voltage dips.
