ERROR DIAGNOSTICS
WHAT TO DO
F
Either U1N or I1 (selectable) input is lost or the input line frequency is
out of measurable range (45 – 65 Hz).
Check the input signals/wiring.
I
Either of the current inputs is overload (120% or more of the rating).
Check the input signals.
U
Either of the voltage inputs is overload (120% or more of the rating).
Check the input signals.
