Motion Safety Feature (Optional – Standard and Master Users)
A feature may be enabled in which the VAC’s display and keypad will become inoperative when the VAC
senses that the vehicle is in motion. This feature requires that the VAC is monitoring vehicle motion via
its serial data interface. It is used to prevent drivers from interacting with the VAC during vehicle
operation, a possible safety hazard. When logged in, Standard or Master users’ displays will become blank,
and a single, blinking cursor will appear on the display when the vehicle is in motion. Additionally, the
keypad will be inoperative. Upon stopping, the display will resume on the same screen as when it went
blank.
Note: Maintenance users can always see their display and use their keypad, permitting them to address
VAC installation or reconfiguration, even when motion-sensing is not properly configured.
Battery Rotation (Optional Module - All Users)
The Battery Rotation module optimizes vehicle battery life by maintaining the state of each battery in the
system and automatically suggesting replacements for discharged vehicle batteries. When a battery has
sufficiently discharged and should be replaced, the battery rotation module is used by the vehicle operator
to request a replacement for this battery.
With a prox-card assigned to each battery, the system can validate whether the operator followed the
recommendation or took an alternate (for example, if the recommended battery is damaged). After a
vehicle is powered down for more than 30 seconds (minimum for a valid battery swap), the VAC requires
the operator to present a valid battery prox-card when logging in. This prox-card should be attached to
the newly added battery. The VAC validates the prox-card and only accepts cards that represent actual
batteries.
Configuration of the module and corrections to battery assignments are made through the
WANConsole’s Battery Rotation Tool (see WANConsole User’s Guide). The system supports corrective
action through a graphical user interface, on any computer installed with the Console, for reassigning
batteries to chargers and vehicles, and for taking equipment out-of-service as needed.
The system expects that discharged batteries are placed on the same charger from which the new battery
is taken. Note that if the actual swap was not a ‘swap-in-place’, the charger number associated with the
discharged battery will be incorrect (though the charging area will still be correct). Note that if an operator
did not follow a recommendation, but performed a manual swap (e.g. by driving to the nearest charging
area and manually looking for an appropriate, charged battery), recommendations sent to other drivers for
