SYSTEM SETUP REQUIRED

message on start-up

Check the MPS installation as per Appendix 2 – Scan head installation and alignment. Ensure the scan area is completely clear on start-up and the scan area markers/barriers have not shifted.

If the problem cannot be resolved by re-aligning the scan head, check:

• scanner lenses are clean
• there are no puddles of water on the scan track
• no vegetation, barriers, cables or other objects are overhanging or protruding into the scan area above ground level.

TRAY SHAPE MISMATCH or OFF CENTRE

errors occur repeatedly for all vehicles

Check that:

• no vegetation, barriers, cables or other objects are overhanging or protruding into the scan area above ground level
• there are no extra objects on the ground
• trucks are completely on the scan track before scanning starts and not turning off the scan track before the scan is complete.

TRAY SHAPE MISMATCH

error occurs repeatedly for a particular truck/trailer unit:

Changes that could produce this error include adding or removing:

• topper/cheater side-boards
• tarpaulin/cover
• tailgate

Also, check that:

• any covers are fully stowed (not hanging into tray, fully pulled forward)
• the truck is following the correct path on the scan track during scanning.

COVERED/OVER-FULL or TRAY SHAPE MISMATCH

error occurs unexpectedly for a particular load

If the bin is loaded to the very top all the way around the edges of the bin or a very humped load blocks the scan head’s view of the tray sides, the system may be unable to identify the load-bearing section of the vehicle.

Otherwise, check that:

• covers are in fully stowed position
• no branches, rocks or such like are overhanging the side of the bin
• the truck is following the correct path on the scan track during scanning
• the load is not loaded to one side of the tray, causing tray to tilt excessively
• the hoist is not partially raised (tipper bins).

VISUAL POLLUTION

displays continuously

Wait for dust, fog or steam to clear or provide external dust control.

Check that the scan area is clear of unwanted objects, puddles of water, ice or overhanging vegetation and that markers/barriers are correctly positioned.

If unsure where the visual disturbance is occurring, open the System screen and view the scanned longitudinal and transverse profiles.

VISUAL POLLUTION (DIRTY LENS)

displays continuously

Clean the dark plastic lenses on the two laser scanner modules in the scan head. (See Cleaning the scanner lenses.)

VISUAL POLLUTION (DIRTY LENS)

message after start-up on a cold or humid day

Built-in heaters automatically turn on and the system will return to normal ready state after the ice/condensation has cleared.

VISUAL POLLUTION or VISUAL POLLUTION IN TRAY

error after scanning a vehicle

Ensure vehicles stop completely before scan head and allow dust, steam or fog to settle before scanning.
A VISUAL POLLUTION IN TRAY message indicates the source of visual pollution is coming off the load itself. The load may be releasing high levels of dust or steam.

This is most likely immediately after loading.

In this case, wait for dust/steam to settle before scanning. Otherwise, check the tarpaulin/cover is stowed correctly and not hanging into the bin or flapping around.

Check that other objects, such as a crane or grapple boom, are not covering the load.

This error can also occur if the load profile is too uneven (lumpy) for the system to measure.

The MPS is intended for measuring particulate (granular) bulk product and attempting to measure unsuitable load types may trigger this error.

Branches or other random objects embedded in a load or a very large variation in the size of load particles may trigger this error.

NO DATA LINK

message displays continuously

Check the following, and contact Loadscan technical support if this problem does not go away:

• Cable between the power box and the scan head is firmly plugged in at both ends and there is no cable damage.
• Cable between power box and operator console is firmly plugged in at both ends and there is no cable damage.
• Visible LEDs on the scan head laser modules light up when system is powered up.

SCANNER NOT FOUND, SCANNER COMMS ERROR, SCANNER STATUS ERROR

or similar error message does not go away

Open the System screen and check the status messages for transverse and longitudinal lasers.

Try restarting the system (shutdown and re-power ALL system components).

Contact Loadscan technical support if this problem does not go away.

Nothing happens when power turned on

Check that:

• the power source is correctly connected to the power box and turned on
• all power and data cables to MPS system components are connected to the power box
• the circuit breaker (fuse) inside the power box has not been tripped
• the power isolator switch on the outside of the power box is in the ON position.

If running the system from a generator, check the output is stable and within voltage limits.

If using power conditioning hardware/UPS, check this is switched on and the output is live.

Automatic identification fails for a specific vehicle fitted with ID tag(s)

Try registering new tag(s) to the affected vehicle.

If this does not fix the problem, try alternative tag mounting locations as there may be interference from immediate surroundings. (See Automatic vehicle identification for mounting instructions.)

Check ID tag(s) are correctly registered in database record(s) for affected vehicle.

Automatic identification fails for all vehicles fitted with ID tags

Open the System screen and check that the tag reader module is reading tags. (See System hardware checks.)

Contact Loadscan technical support if problem does not go away.

Automatic identification identifies wrong vehicle

• the correct ID tag(s) have been fitted and registered to the correct vehicle
• no additional ID tags are being carried aboard the vehicle
• no ID tags are being stored in the area around the scan head
• no ID tags have fallen off a vehicle and are lying on the ground near the scan head
• no other vehicle fitted with ID tags passed in an adjacent lane during scan
• no other vehicle fitted with ID tags followed too close behind the scanned vehicle.

Scanning does not start when vehicle reaches scan head

or,

Scanning starts or stops part-way through scan

If the vehicle is too far to one side of the scan track so that it is outside the valid scan area or cannot be seen by the longitudinal laser beam, scanning will not start.

If the vehicle turns during scanning or is not aligned correctly with the scan track before reaching the scan head, part of the vehicle may move out of range of the longitudinal laser beam and scanning will stop early or fail to start.

After scanning, the system returns immediately to READY TO SCAN state

or outputs an

INVALID SCAN TARGET error

If the profile is rejected, the scan is discarded and the system returns to ready state.

Depending on the system configuration an INVALID SCAN TARGET error may be generated.

This is intended to reject scans triggered by large dust or fog clouds, under-size or oversize vehicles or other unsuitable vehicle types.

This condition can occur unexpectedly if:

• a vehicle is accompanied by a cloud of dust or fog or excessive dust or steam is coming directly off the load
• a vehicle reverses through scanner
• bin walls/floor are not solid (e.g. mesh, frame-work or lots of holes)
• bin(s) are covered
• a vehicle is off-centre during scan
• a crane, grapple boom or other large object is overhanging the bin
• vegetation, barriers, cables or other objects are overhanging or protruding into the scan area.

TOO FAST, TOO SLOW, SPEED UNEVEN or TRACKING ERROR errors when vehicle speed normal

• vehicle position during scanning is not off centre such that the longitudinal laser beam is partially or completely missing the vehicle
• the vehicle is not overloaded so that the hump in the load blocks the longitudinal laser scanner from seeing the front or rear of the vehicle
• no other vehicle is in the scan area during the scan.

Unexplained TRAY PROFILE ERROR during empty reference scan

This error can also occur if vehicle is too far off centre during the scan.

OVERHANG TOO BIG (FRONT OR REAR) error during empty reference scan

It can also be triggered if:

• the vehicle is too far off-centre
• longitudinal (lengthways) obstructions such as crane or grapple booms are in line with the longitudinal laser during scanning.
• tensioning straps are in line with the longitudinal laser during scanning.

Message board is blank or message does not change

Open the System screen and push the SIGN TEST button. This sends a test message to the message board.

If the message board and MPS operator console are on separate power supplies, ensure the message board is always turned on at the same time (or before) the operator console is powered up.

Contact Loadscan technical support if this problem does not go away.
