Cause
External fuse for the supply vol-
tage has triggered.
The measurement voltage is not
connected.
The measurement current is not
connected.
Current measurement is in the
wrong phase.
Current converter factor is in-
correctly programmed.
Measurement in the wrong pha-
se.
Voltage converter is incorrectly
programmed.
Measurement range exceeded.
The voltage peak at the measu-
rement input has been excee-
ded due to harmonics.
Remedy
Replace fuse.
Connect measurement voltage.
Connect measurement current.
Check connection and correct if
necessary.
Read current converter transfer
ratio on the current converter and
program it.
Check connection and correct if
necessary.
Read voltage converter transfer
ratio on the voltage converter and
program it.
Use a voltage converter.
Warning!
It is necessary to make
sure that the measurement inputs
are not overloaded.
