In AVR-1 STANDARD, the function of setting the switching delay time has
been implemented. Using the potentiometers on the control panel, you can
adjust the delay time for switching power from the primary input to the reserve
(T1) and from the reserve input to the primary (T2). It is necessary to turn the
potentiometers clockwise to increase the switching delay time and
counterclockwise to decrease it.
Control over the presence of voltage in the AVR is carried out using control
conductors. In AVR-1 STANDARD, control is carried out in 3 phases of both the
primary and reserve inputs, in AVR-2 LITE; control is carried out on one phase of
both the primary and reserve inputs.
Procedure for replacing the circuit breakers are listed in the table 4.
AVRs (automatic transfer switches) are equipped with LED status indication.
AVR-1 STANDARD are equipped with LED indication of main input (main
input voltage indicator, position indicator of the main contact group of VA
(automatic circuit breaker) main input) and LED indication of standby input
(standby input voltage indicator, position indicator of main contact group of VA
standby input).
If there is voltage on the main input, the red LED of the main input - UI (I) is
on.
If there is voltage on the standby input, the red LED of standby input - UII (II)
is on.
When VA of the main input is closed, the green LED of the main contact
group position of the main input -ON is on.
When the VA of the standby input is closed, the green LED of the position of
the main contact group of the standby input - ON is on
If the connection diagram is incorrect, or the supply voltage is incorrect, the
AVR will signal with blinking green and red LEDs, with frequency of 1 time/sec.
When the AVR is tripped by overcurrent, the AVR will signal with blinking
green and red LEDs, with frequency of 1 time/sec.
AVR-2 LITE are equipped with LED indication of main input (main input
voltage indicator, position indicator of the main contact group of VA (automatic
circuit breaker) main input) and LED indication of standby input (standby input
voltage indicator, position indicator of main contact group of VA standby input).
If there is voltage on the main input, the red LED of the main input - AC is on.
If there is voltage on the standby input, the red LED of the standby input - AC
is on.
