RANGE
201
Nominal voltage measurement = phase voltage
100...241500
V
Setting the correct nominal voltage is needed because from this
value the upper and lower limits for voltage monitoring is calculated
(See. Nominal voltage tolerance range). The Step sizes stored in
Step database relate to the adjusted nominal voltage.
202
Current transformer ratio
1...9600
Setting the CT factor.
Value must be entered as the ratio (e.g. 1000 / 5 = 200)
At devices with software version 1.04 is the adjustment range from
1-4000.
203
Voltage transformer ratio
1...350
Stetting the VT factor.
Value must be entered as the ratio. If the device is directly
connected to the measurement the value 1 has to be used.
204
Nominal voltage tolerance range
0...100
%
The setting of this value is in percent related to the nominal voltage.
By means of the set value, the upper and lower limits of the
permissible voltage range are calculated. e.g. 10% at 400V nominal
voltage is a permissible range from 360V to 440V.
205
Connection voltage measurement
Yes/No
"YES" voltage measurement L-L
"NO" voltage measurement L-N
Based on the set voltage, the controller automatically detects the
voltage for both types of connection (LL and LN). If these are
within the set tolerance (factory s/- 10%) the controller shall
determine the voltage measurement. This cannot be changed by
hand.
If the measured voltage is outside this tolerance, the measurement
can be adjusted by hand.
