— watchdog (external)
— watchdog (internal).
Fault recording
Fault events are recorded in the controller’s memory. Multiple occurrences of the
same fault are recorded as one occurrence.
The fault event list can be loaded into the programmer for readout. The
Special Diagnostics mode provides access to the controller’s diagnostic history
file—the entire fault event list created since the diagnostic history file was last
cleared. The Diagnostics mode, on the other hand, provides information about
only the currently active faults.
Fault recovery (including recovery from disable)
Almost all faults require a cycling of the KSI or brake/seat switch input to reset
the controller and enable operation.
The only exceptions are these:
FAULT RECOVERY
anti-tiedown release and re-select Mode 1
contactor overcurrent when condition clears
emergency reverse re-apply BB or cycle brake
HPD lower throttle to below HPD threshold
overvoltage when battery voltage drops below overvoltage
SRO when proper sequence is followed
thermal cutback when temperature changes
throttle fault clears when condition is gone
undervoltage when battery voltage rises above undervoltage
(all other faults) (cycle KSI or brake/seat switch)
