URRENT MEASUREMENT
Figure 4-1: Current measurement commissioning procedure.
Current measurement channels should be adjusted to the pick-up setting value by:
1)
Injecting the current level of desired pick-up value to IL1 and Io separately.
2)
Starting from maximum setting, adjusting the potentiometer slowly down.
3)
Corresponding current measurement channel LED lights steadily when the
activation with injected current has occurred.
IL1 – IL3 measurement channels have a common adjustment
potentiometer "I>set". Therefore, each current channel is not
necessary to commission separately. Alternatively, channels IL1 – IL3
can be injected with the same current in serial connection.
After successful commissioning, the device has to be re-installed
according to the instructions on chapter 3.1.
