• The fault value describes a component contained in the ring
• Fault value (r0949, interpret hexadecimal): ccbbaaaa hex: cc = connection number (%3) bb = component class (% 2) aaaa = preliminary component number (%1) Component class: 0: Component unknown
• 1: Control Unit 2: Motor Module 3: Line Module 4: Sensor Module 5: Voltage Sensing Module 6: Terminal Module 7: DRIVE-CLiQ Hub Module 8: Controller Extension 9: Filter Module 10: Hydraulic Module
