Start Value - DEMA 400 Series User Manual

4.3.2.6.2

Start Value

The display shows how many times the nominal current value starts when the protection is
active. Selection is made in (0.05-1)I
4.3.2.6.3 Operate Delay
The operation delay determines the characteristic of the protection curve with the delay type.
The delay type is DMT characteristic, the delay can be in the range of 0.02 - 200 s.
4.3.2.6.4 Reset Delay
According to the menu settings, exceeding 5.00 In and without breaker tripping, It was
selected to count the DMT (constant time) reset time (0.04 s) after the current has dropped
below 5.00 In. 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).
4.3.2.6.5 Inhibit on 52A
The 52A function must be assigned to any of the programmable inputs so that the phase low
current protection function can operate properly. If the selection is active, the control is
provided for the 52A function; passive means that the control is deactivated.
4.3.2.6.6 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.
4.3.2.6.7 U< Locking Level
When "Inhibit on U" is activated, U< Locking Level is displayed on the device display to set
the lock level. This level can be selected in the (10 - 220) V range.
4.3.2.6.8 Measurement Mode
The measurement mode can be selected as RMS or Basic Sequence. The basic sequence
measurement is selected to use harmonic-free measured values. The RMS(Root Mean Square)
