ESCRIPTION
STOP The error information is recorded in NVRAM and the unit is
placed into Safe State. The only functionality available to the
user is serial communication, turning off the audible alarm
via a key press and removing power.
REBOOT The error information is recorded in NVRAM and the unit is
rebooted. The fifth occurrence of a REBOOT level error
within a 24 hour period (while power is maintained), will be
promoted by the system to a STOP level error.
ABORT The error information is recorded in NVRAM.The fifth
occurrence of a ABORT level error within a 24 hour period
(while power is maintained), will be promoted by the system
to a STOP level error. This error is similar to a Reboot-Level
Error with the exception that the system is unable to handle
the error prior to the reset, e.g. watchdog timeout.
CONTINUE The error information is recorded in NVRAM and the unit
continues to operate without noticeable alteration.
