3 PRE-STARTING PROCEDURE
3.1. With use of the front panel knobs, set the maximum (
U
max
) and minimum (
U
min
) voltage tripping
thresholds then set the autoreclosing time delay depending on the type of device to be protected (AC units,
refrigerators, and other compressor-based devices allow re-start after no less than 3-4 min, other instrumen-
tation reset delay shall be set in accordance with their operating instructions).
3.2. Turn ON the power and if necessary set adjusted values for maximal and minimal voltage, as well as
the autoreclosing time delay. On turning the knobs front panel digital indicator will show corresponding
parameter values simultaneously with flickering points in the lower order.
3.3. When necessary, push the overcurrent protection breaker switch button.
4 RELAY OPERATION
The relay have several functional states which are as follows:
-normal state;
-voltage fault;
-current fault;
- autoreclosing (
AR
) time delay countdown.
The relay is in the normal state when the monitored voltage is within the specified limits, the overcurrent
protection breaker is closed and the
AR
delay time has expired. In this state, the load is connected to the
mains, the LOAD LED is ON, and the display shows the monitored voltage value.
If the monitored voltage value gets lower than the user-preset limits for the time that exceeds the
specification, the relay switches to the voltage fault state. In this state, the load is disconnected from the
mains, the LOAD LED turns OFF, and the display flickers the monitored voltage value.
After the voltage returns back to normal level, and if the
AR
delay time has not yet expired, the relay
switches into the state of the
AR
delay countdown indication. In this state, the time in seconds remaining
before the relay transfer to the normal state is displayed, and the low order digit flickers a point. After the
AR
delay time is over, the relay switches to normal operation mode.
