Step:
1 A
Range:
1
– 5000 A / 5A
Hint:
Generator currents and power measurement is suppressed if current level is bellow <1% of CT
range.
For firmware versions <= 1.4:
For CT Ratio <= 250 the values of power and current are displayed in a controller with one decimal.
For CT Ratio > 250 the values of power and current are displayed in a controller with integral
numbers. If you change CT Ratio in LiteEdit or directly in the controller, decimal numbers will not be
changed immediately. The change will be executed only by reconfiguring in LiteEdit. The statistics of
power will be recounted at this time with regards to decimal numbers of power.
WARNING! When you change the firmware, statistics can be invalid! Check the
statistical values.
If necessary value change is possible by LiteEdit software (password is required).
WARNING! Change of CT ratio over value 250 without reconfiguring in LiteEdit can cause
overflow of current measurement and improper function of controller!
WARNING! For CT Ratio <= 250 the measured current on generator or mains shall not be
bigger than:
6500A or
equivalent of 3200kVA on any phase or total kVA or
equivalent of 3200kW on any phase or in total kW.
For CT Ratio > 250 are the same conditions with limits of 65000A, 32000kVA and 32000kW
.
For firmware version >1.5:
Decimal switching is not done via value of “CT ratio” setpoint, but in configuration window of LiteEdit
sof
tware via icon „Units/Formats“.
WARNING! In case of one decimal displayed at power values the measured current on
generator or mains shall not be bigger than:
6500A or
equivalent of 3200kVA on any phase or total kVA or
equivalent of 3200kW on any phase or in total kW.
For no decimal displayed are the same conditions with limits of 65000A, 32000kVA and
32000kW
.
