A-Stop transmitter

The A-Stop transmitter is a hand held unit that can be carried by each individual within the area of autonomous operation. A-Stop transmitter runs off a rechargeable, 1.2 V NiMH battery which is charged using the port on the side of the transmitter. The transmitter sends signals at a 919 MHz fixed frequency to the A-Stop receivers within the transmitter operating range. The transmitter can stop every autonomous machine within approximately 300 m (984.3 ft). The transmitter also has LED indicator lights for Stop, Clear, Test, Low Battery, Battery Charging, and Battery Fault functions. The transmitter will enter a power-saving sleep mode after 24 hours of inactivity or can be triggered manually.

Power and charging

  • Use only the provided 12 V charger 373-8621 Battery Charger for charging the A-Stop remote transmitters.

  • The devices should be charged as needed (recommended every 1-3 days with normal use). The battery light on the face of the device will blink when the battery is low. An audible sound can also be heard from the device when the battery is low.

Note: The device must be in use to hear or see the low battery indication, so care should be taken to charge the device regularly.

  • The charging port can be found on the bottom left of the remote transmitter. Lift the rubber sealing plug and insert the 12 V charger plug into the bottom of the transmitter.

  • When the ON LED stops blinking and remains a solid blue color, the device is done charging and can be removed from the charger.

  • Replace the sealing plug when not charging.

A-Stop Checkout Station

A-Stop Checkout Station

The A-Stop Checkout Station is used to test the operation of individual A-Stop transmitters. The checkout station allows the system to verify that the transmitter is working properly, and records which transmitters have been checked out and to whom.

  • Transmitters can be assigned to individuals using the Cat® MineStar system software program.

  • There may be multiple checkout stations at one mine site to facilitate sufficient access for personnel entering the autonomous operation zone.

  • A transmitter may be retested after the transmitter has been allocated to a user, before the transmitter is returned.

  • If a device is allocated using a remote computer with the test station, the allocation will be displayed in the A-Stop page within the Cat MineStar System Client software.

Testing A-Stop Transmitters with a Cat MineStar System Remote PC

The A-Stop test functionality is built into the Cat MineStar System software. A transmitter can be tested anytime a working test station is in range. A transmitter must be tested within 15 minutes prior to being allocated to a user.

Testing the Transmitter

  1. Navigate to the A-Stop tab of the remote Cat MineStar System computer.

  2. Verify that the transmitter has an adequate battery charge. Press and hold the test button, then press the stop button immediately after to initiate the test. Release both the buttons.

The checkout station will check the transmission of the test signal. The system will acknowledge the signal and display the test results on the "A-Stop Station" tab.

Note: Pressing the Stop button alone can trigger an A-Stop. Follow the procedure to avoid triggering the A-Stop unintentionally.

Test Results

Test results in Web Version

The above image is the "MineStar Web Version" A-Stop test station results page.

  1. Click "Tasks" tab on the top of the results page.

  2. Select "Automation" in the drop-down.

  3. Select "A-Stop" tab.

Test results view screen

The above image is the "MineStar System Client" test results page.

  1. Click "Contents" on the top "Toolbar".

  2. Select "Autonomy" in the drop-down.

  3. Select "A-Stop Page" tab.

After testing the transmitter, the results and information can be viewed on screen. If a result shows a failed test, the following condition is the possible cause for failure:

The transmitter does not have an adequate charge for operation and requires additional charging before use.

Note: If the transmitter continues to fail the test after two attempts, the transmitter should be taken out of service for further troubleshooting.

After the transmitter has passed the test, the transmitter can be allocated to a user.

Allocating a Transmitter to a User

(1) Allocate button

  1. Select the row of the transmitter that is to be allocated to a user.

  2. Use the allocate button (1) located in the top right of the screen to allocate a transmitter to a user.

  3. A pop-up window will appear and a name can be selected from the list of known users or the name of a guest user can be entered into the field at the bottom of the screen.

    1. If a transmitter has already been allocated to another user and is selected to allocate to a new user, the test station will allocate the transmitter to the new user if the transmitter has been tested within the last 15 minute period.

If the transmitter has not been tested within the last 15 minute period, return the transmitter back into the system and follow the normal test and allocation procedure. Refer to Section "Returning a Transmitter" for more information on returning a transmitter.

Note: An A-Stop transmitter that has not been tested using the A-Stop test station or checked out is still capable of stopping an autonomous machine providing the transmitter is in proper working condition.

After a user is selected from the list or given a guest user name, the transmitter is allocated and the test results screen will be updated to show to whom the transmitter is allocated. The transmitter can also be retested and a check box will appear in the test results window under the "Re-Tested" column to show a successful retest. This retest feature can also be utilized for users returning to work after a break or period of activity to verify proper operation of the transmitter without allocating a new user.

Returning a Transmitter



Illustration 7g06061621
(2) Allocate button

After the transmitter is returned to the test station area and no longer needed for use, open the Cat MineStar web version, then select the Allocate button (2) to return the transmitter. The test results window will be updated to show that the transmitter is returned.
