Operating the Vehicle
Break Mode
The VAC’s “Break” option is available to all operators. This function allows an
operator to reserve his/her vehicle for short periods of time (The default time is
15 minutes). To enter Break mode, from the VAC menu screen, select BREAK.
While in Break mode, the screen indicates that only the operator who put the
vehicle into Break mode, a Master operator or a Maintenance operator can log
into that vehicle. All other operators are prevented from logging into the VAC
on that vehicle. After the break time-period, the screen changes to the standard
screen and any operator will once again be able to log into the VAC on that
vehicle.
Idle Timeout
If an operator does not log off the VAC after using a vehicle, anyone could drive
that vehicle under the operator’s name, resulting in the loss of access control
and accountability for vehicle use. To prevent this unsafe practice (and to save
vehicle wear and wasted fuel), the VAC will automatically time-out after a
vehicle has been idle for a period of time (The default time is 10 minutes).
When the idle timeout occurs, a countdown appears on the VAC screen and the left LED alternately blinks green and orange
to alert the operator of the impending idle timeout. At the end of the countdown, the VAC logs off the operator and shuts
the vehicle down. To cancel the timeout, the operator can move the vehicle or from the VAC menu screen, select the
SNOOZE. To use the vehicle after an idle timeout, an operator must log in again using their iButton fob/ Access ID.
Automatic Hibernate
On internal combustion vehicles, the VAC has an automatic power-down
function to conserve vehicle battery power. The automatic hibernate feature
puts the VAC and any peripherals into a “hibernate” mode that uses much less
power than the VAC’s active mode. The VAC will automatically enter h
ibernate
mode after 35 minutes of vehicle inactivity after operator log off.
In Hibernate mode, the VAC periodically samples for activity and sends check-in
records to the software. If any activity (motion, login, etc.) is sensed during the
check-ins, the VAC will return to full power mode. Alternatively, you can
restore the VAC to its active state (“Wake up the VAC”) by pressing the VAC’s
POWER button (See Section 2 “Logging onto the VAC”).
Another activity example is (engine, login, etc.)
