Code 231-E021: Cut-out signal status incorrect CC%2 Nom:%4 ErrMask:

%5 Sgn:%6 [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, decimal 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, decimal notation, interpret in binary): 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
