Chapter 4 Status and Troubleshooting
Clear Faults To clear faults in the access box, you must cycle one of the fault reset signals
(GeneralFaultUnlatch or LockSequenceFault Unlatch) as specified in Table 6
on page 38.
The reset requires a leading and trailing edge of the reset signal within a
specific time frame. The pulse width must be between 10 ms…10 s. If the pulse
width is too short or too long, the reset function is not executed.
Figure 20 - Fault Reset Timing
Multiple Faults
It is highly unlikely that more than one fault will occur at the same time. If a
new fault does occur before a previous fault has been cleared, a new value is
written to FaultCode, which deletes the previous one. The DiagnosticActive bit
is set with each fault, but does not change state if the second fault occurs
before the first fault is cleared.
