AVR-3/3-22
Purpose
The device of automatic input of a reserve with microprocessor management ABP-3/3-22 is intended for control of tension on two independent three-phase inputs and reservations of food of two three-phase loadings by means of the external actuation mechanism containing the section switch.
Construction
The ABP-3/3-22 block is executed in the case for installation on a DIN lath or the assembly panel.
On the forward panel of the block there are handles of regulators of installation of an operating mode, indicators of a condition of a network and indicators of a condition of the relay.
In the top and lower part of the block there are terminal blocks for connection of the block.
Power supply of the block is carried out from a controlled network.
Warranty period – 2 years.

Technical characteristics
Preparation for operation and operation
Before operation it is necessary to study the maintenance instruction of the AVR-3/3-22.
To install the block in an electroboard and to make connection of the controllable networks of the 1st and 2nd input, chains of management and the alarm system it agrees to marking: L1, L2, L3 (INPUT 1) – phases of the 1st power input; L1, L2, L3 (INPUT 2) – phases of the 2nd power input; N – a neutral (the general for the basic and reserve inputs); 11 – the switching contact; 12 – normally the closed contact; 14 – normally opened contact (for the internal P1, P2 and P3 relay). Section of the connected wires has to be not less 1,0 mm2.
To expose necessary parameters of a controlled network.
To make connection at the de-energized inputs of a network!
It is forbidden: to open the block which is energized networks.
Operation of the ABP-3/3 block-22
To include a three-phase network on the 1st and 2nd input. To check operation of the block on light-emitting diodes.
At the network tension corresponding to the set parameters have to be contacts of 11-12 P1, P2 relays are closed and light-emitting diodes of "P1", "P2" are included, "L1, L2, L3 – INPUT 1" and "L1, L2, L3 – INPUT 2".
If at connection of a controlled network the order was broken alternations of phases on the 1st or 2nd input, there is a blinking corresponding light-emitting diodes of "L2", "L3", thus any relay not will join. It is necessary to disconnect a network, to make change of phases and repeatedly to include a network.
If in operating time on the 1st or 2nd input there is an accident (loss of a phase, break of a neutral or discrepancy of tension to the set to values), there will be respectively a shutdown of the P1 or P2 relay and the P3 relay will turn on with a temporary delay "Δt (in C), with". At normalization network tension on the 1st or 2nd input through time "Δt (return), with" the device has to return to an initial state (item 5.2). All modes works are followed by inclusion of the corresponding light-emitting diodes, see. table:
