Motion Safety Feature
The VAC’s display and keypad are inoperable and log
-off is prevented for
Standard and Master operators when vehicle motion is detected. This safety
feature prevents Standard and Master operators from interacting with the VAC
while the vehicle is moving.
Note:
Maintenance operators can always see the VAC’s display and use the
VAC’s keypad, even if the vehicle is in motion, to enable Standard and Master
operators to perform VAC configuration or troubleshooting.
Event Shutdowns (Impact, safety non-compliance, etc.)
For certain unsafe events, the VAC will prompt the operator that the vehicle
will shut down within 30 seconds (only if the vehicle is in Registered ID mode)
and a countdown will begin. “High” and “Severe” impacts, safety
checklist non-
compliance, and checklist critical responses all result in vehicle lockouts and
require Master or Maintenance operators to ‘unlock’ the vehicle. These events
are preconfigured in the VAC and Vision Pro software.
Memory Status
The VAC has onboard memory is capable of retaining different types of data for
various durations. In cases where the VAC remains outside of wireless coverage
for extended periods of time, the VAC will prompt to drive to a WAM or Access
Point. To check the VAC memory status at any time, from the VAC menu screen,
select MEMORY STATUS. The VAC displays the memory consumed in a
percentage.
The VAC Memory Status can be cleared by certain operator authorization levels.
Select CLEAR MEMORY.
Clearing memory erases any performance data (vehicle usage, checklists
completed, events occurred, etc.) not yet sent to the software, and forces the
VAC to resynchronize before standard operators can login.
