3.9 UxC 11x (FS): Meaning of the LEDs
On the front of the UxC 11x (FS) are several LEDs for functional control, with
the following meaning:
UxC 11x LED Meaning Signal
direction
Signal
NC RESET Reset signal from the MC
computer unit to the UxC
MC → UxC RES.LE
PWR FAIL U
Z
too low, U
Z
< 410 V (e.g.
failure of a phase under load,
power < 290 V)
UxC → MC PF.PS
PWR RES Reset signal from the UxC to
the MC computer unit
UxC → MC RES.PS
READY Inverter ready UxC → MC RDY
TEMP >> Temperature of heat sink
too high (> 100 °C)
UxC → MC ERR.TEMP
