Features:
- Hardware safety chain: KA16 and KA17 participate in the controller motor-on path
- Dual-board supervision: SIB and MIB compare run and brake feedback chains
- Paint-cell interlocks: cabin and high-voltage conflicts affect the paint-enable path
SIB-02 supervises multiple hardware safety paths within the IRC5 controller instead of operating as a general-purpose interface card.
Its engineering value lies in coordinated feedback: the controller compares safety-chain states across the installed board set and reacts according to the affected chain.
Service records should connect the full board label, reported chain, PIB and MIB context, cable state, and completed machine-safety validation.
Apter Power can review SIB-02 controller context, safety-chain evidence, condition, and sourcing requirements.

- Cyclic enable test: the controller supervises the safety path through repeated SPI communication checks.
- Watchdog boundary: internal SPI watchdog events distinguish communication loss from a field interlock.
- Board path: inspect the PIB-to-SIB and SIB-to-MIB connections named by the reported event.
- Run or brake conflict: divergent chain feedback can place the controller in SYS HALT.
- Cabin or HV conflict: a paint-interlock mismatch can open the paint-enable chain.
- Supply feedback: missing fail-safe or emergency-stop supply feedback must be traced before board exchange.
- Event-led diagnosis: begin with the specific run, brake, emergency-stop, cabin, or high-voltage chain reported by IRC5.
- Two-board comparison: preserve evidence from both SIB and MIB rather than replacing one board on appearance alone.
- Return to service: validate the complete safety function after the communication and field paths are restored.
- IRC5 safety supervision: monitor the controller hardware chains used for motor-on permission.
- Paint-cell interlocking: supervise cabin and high-voltage interlock feedback in supported installations.
- Chain-specific troubleshooting: separate SPI communication, board feedback, and field-circuit faults.
