4.3.3.2.1 Protection
activated in the active state and disabled in the passive state.
4.3.3.2.1 Start Value
It is the screen where the protection of the phase-to-neutral voltage value is set when the
protection is active. The selection is made in the (1 - 130) V range.
4.3.3.2.3 Operate Delay
The operation delay is the value that determines the characteristic of the protection curve with
the delay type. In the case of voltage protection, the delay type must be DMT. This delay is
expressed by the term tI >> and may be in the range of 0.02 to 600 s.
4.3.3.2.4 Reset Delay
According to the menu settings, exceeding 200V and without breaker tripping, It was selected
to count the DMT (constant time) reset time (0.04 s) after the voltage has dropped 200V.
Thus, after the current falls below the threshold, 40 ms will be counted. If the threshold is not
exceeded until the end of this period, the protection function trip time counter will be reseted.
Reset delay thresholds are in the range of (0-60).
4.3.3.2.5 Inhibit on U<
If this setting is active when the device is subjected to low voltage, the blocking of the
undervoltage protection is activated.If it is passive, blocking of the undervoltage protection is
deactivated.
lock level.
4.3.3.2.6 U< Locking Level
device to set the
lock level.This level can be selected in the (10 - 220) V range. Be ensure that the undervoltage
protection level is not greater than the minimum voltage value.
