Fault management
There are two types of faults:
• Resettable faults by fault acknowledgment.
• Blocking faults that require a restart of the +24V DC supply of the Inobox module.
Whatever the type of fault triggered, the regulation cuts off the high voltage and the
powdering.
The Fault relay is controlled.

Description
1 - Program fault
Microcontroller module fault. This fault requires a
power-on to be ressetted.
2 - +24V power supply fault
The in24VDC power supply may fail. it has
exceeded the authorized operating limits : 21 V < U
< 28 V. This fault requires a power-on to be resset-
ted.
5 - Voltage coherence fault
Voltage present on the bus without HV request. The
fault requires a power-up to be acknowledged.
HV request without voltage present on the bus. The
fault can be reset by acknowledgment of the fault
after a 10-second wait.
17 - Absence of control
mode fault
The CAN Communication is lost while the API is in
control mode. The fault can be reset by
acknowledgment of the fault
21 - Bus power fault
The output power of the module or the inverter cur-
rent has been exceeded.
Resettable by Fault Acknowledgment.
22 - Safe shutdown fault
The maximum high voltage current or the supply
current of the barrel has been excedeed .
Resettable by acknowledgment of fault.
24 - Trigger request at star-
tup
The external high voltage/powdering control trig-
ger is controlled when the module is powered on.
Resettable by Fault Acknowledgement
28 - Temperature fault
Exceeding the maximum temperature (75°C) of the
internal power supply of the module. Resettable by
Acknowledge Default if the temperature has fallen
below 60°C.
