    R1:	If	Reading of SENi is Abnormal
    	and	( forall k <> i | influences ( SRCk, SENi ) )
    		Reading of SENk is Normal
    	then	set Malfunction of SRCi to True.
    
    
    R1.5:	If	Temperature of RCE-BEARING-SENSOR-22 is High
    	and	( forall k <> i | influences ( SRCk, RCE-BEARING-SENSOR-22 ) )
    		Reading of SENk is OK
    	then	set Malfunction of RCE-BEARING-6 to True.
    
    
    R2:	If	Temperature of RCE-BEARING-SENSOR-22 is High
    	and	Temperature of RCE-SENSOR-34 is OK
