User's Manual

When a truck receives an A-Stop stop signal, the
truck immediately initiates a controlled stop. While
the truck is in a
utonomous mode with A-Stop active,
the autonomous mode and A-Stop lights will be
flashing. Refer to Illustration 5 for an example.

The truck identifies and records which transmitter or
transmitters have initiated the A-Stop. The truck can
only resume autonomous operation when an A-Stop
clear message is received from all the transmitters
that the truck received a stop message from. Once
the truck has received a clear message from every
transmitter that the truck received a stop message
from, the truck will deactivate the A-Stop and the
A-Stop light with stop flashing. Refer to Illustration 6
for an example.
Resuming Autonomous Operation
When the truck has received all the necessary clear
messages, the truck is ready for a new assignment.
The truck will not automatically resume the task that
was assigned prior t o the A-Stop. The truck requires

Testing the A-Stop System
An A-Stop transmitter can test the transmitter and
truck system by using the test button (4). Press and
hold the test button for 2 or more seconds while in
range of one or more autonomous trucks. The trucks
that receive the test message will acknowledge the
test by honking the truck horn.
The A-Stop system also has a self-test function.
The self-test is different from a test using an A-Stop
transmitter. Periodically, the truck will send out A-Stop
self-test signals that can detect a system failure all
the way down to the antenna. The truck will notify the
MineStar operator if a failure is detected i n a self-test.
