7.11.15 Actual value adjustment on site
The current and voltage actual value sensing are calibrated in the manufacturer's plant.
● The accuracy
of the ex-factory current sensing is better than +/-1 % of the rated device
current.
● The accuracy of the ex-factory voltage sensing is better than +/-1 % of the rated device
voltage.
The voltage and current actual values can be adjusted "on site", if necessary.
In this way, the voltage and current values that the DCP displays (r55503, r55504, r55520,
etc.) can be adjusted so that they correspond to externally measured values.
The current and voltage actual values can be subsequently adjusted using the following
parameters:
● p55545[0..1] / p55546[0..1]
● p55525 / p55526
Note
Factory calibration
The factory calibration always remains active, and is only adapted by the parameteriz
ed
Note
Accuracy of the actual value sensing
The accuracy of the factory actual value sensing is only valid if all adjustment parameters
are set to 0.00
%.
