Error message

E021 Cutout signal status incorrect CC%d Nom:0x%x ErrMask:0x%x Sgn:%d

Cause of error

An error occurred in the self-test for safety. A faulty output condition was found before the cut-out channel test: At least on of the examined cut-out signals has the wrong condition.
These are the meanings of the abbreviations:
Nom (nominal condition of the cut-out signals, hexadecimal notation, interpret in binary):
0: Lock / 1: Release through the corresponding cut-out signal (bits 0 to 9 of Nom)
Bit0:STOS.A.MC, Bit1:STO.A.MC.WD, Bit2:STO.A.P.x, Bit3:STO.A.PIC, Bit4:STO.B.CC.WD
Bit5:STO.B.P.x, Bit6:STO.A.CC, Bit7:STO.A.SPL.WD, Bit8:STOx.A.RES, Bit9:STO.A.T
ErrMask (error mask, hexadecimal notation):
The corresponding switch-off signal (bits 0 9 of ErrMask) locks although it should release, or releases although it should lock.
Sgn (cut-out signal to be tested):
0: STOS.A.MC
1: STO.A.MC.WD
2: STO.A.P.x
3: STO.A.PIC
4: STO.B.CC.WD
5: STO.B.P.x
6: STO.A.CC
7: STO.A.SPL.WD
8: STOx.A.RES
9: STO.A.T

Error correction

- Check the wiring (PWM cable)
- Replace the defective hardware (power module, controller unit)
- Inform your service agency
