10 CONTROLLER DIAGNOSTIC
10.1 Diagnostic features
The VCM has two microcontrollers which carry out many diagnostic analysis to
check all the internal functions. Each microcontroller carry out its own analysis
independently of the other one and it is capable of raise an alarm code in the
CANbus line.
Moreover many internal functions are stopped if at least one of the two
microcontrollers detects a fault.
The complete list of the Master and Slave alarms is shown in the following table.
The list also shows the corresponding alarm codes in the Zapi format (the same
shown from an MDI or an Eco Smart Display) and in the CANopen format.
