Calculating the Arm Free Safety device : SBD
SBD = /Def capt . [ [IN_ATT_DECAL_1

[447]
) + (ANTICIP . / Déf_PRESSE) ) ]
+ IN_ZBD
[444]
+ (IN_HORS_MACH_1

. V_BH) ]
ANTICIP = anticipated restart running.
Déf_PRESSE = IMM signal coherence detection.
Def capt = Sensor fault = X sensor coherence+ Z sensor coherence except Déf. B1H and Déf. B2H + SBD relay control.
Checking the coherence of the sensor information :
A fault extension number (xx) D_3 : SENSORS NOT COHERENT.....xx enables you to identify the type of fault.
Arm 1 = Electric : The following checks trigger the fault : D_3 : SENSORS NOT COHERENT.....xx.
