Introduction
This manual describes how to install the CAESbasic system. The system is designed specifically for material-moving equipment in the mining industry. The system uses GPS to provide accurate horizontal and vertical blade guidance. This manual provides instructions for installing the system on track-type tractors, motor graders, wheel tractor-scrapers, and other earthmoving machinery.
Pre-installation
Caterpillar strongly recommends that you visit the mine for a pre-installation check. Check all aspects of the installation in advance so that you save valuable time later. Before and during installation you will need to discuss aspects of the installation with people at the mine such as the mine manager, foreman, and machine operators.
Pre-installation Mine Visit and Machine Inspection
When you are at the mine perform the following tasks:
- Identify the machine on which the system is to be installed.
- Get agreement that the system is to be installed on a specific machine.
- Make sure that the machine meets specification so that the system can perform properly.
- Decide on the routing of cables and the placement of equipment.
- Get an agreement on the positioning of the equipment.
- Identify any brackets needed for the specific machine.
- Ensure that there will be a GPS base station on the site that you can use.
- Get agreement on who is providing the mine (GPS) calibration.
- Obtain a list of known survey control points for the mine and their coordinates.
- Identify where the installation is to take place.
- Install the equipment in a fully equipped workshop and steam clean the machine before you start. Installation is easier and faster on a clean machine.
- Allow a full day for two experienced people to do the installation. Allow more time if the installers are inexperienced.
- Schedule the people and equipment required for the installation.
- Make sure that a welder is available, and that the welder knows the size of the plate to be welded.

Operational Considerations
When mounting the equipment, consider safety and ergonomics.
Safety
The safety of the machine operator and other personnel is critical. Do not mount equipment where the equipment will obstruct the view of the machine operator or where the equipment could come into contact with the machine operator during normal operation. Always make sure that the equipment is securely fastened to a solid part of the machine.
Structural damage, an overturn, modification, alteration, or improper repair can impair this structure's protection capability thereby voiding this certification. Do not weld on or drill holes in the structure. Consult a Caterpillar dealer to determine this structure's limitations without voiding its certification. |
Ergonomics
Mount equipment in a convenient location. Make sure that machine operators can do the following:
- See the display screen in their normal field of vision
- Reach the display keypad easily from their normal, seated position
Mount equipment where the equipment will not block access for maintenance. The equipment must not interfere with normal operation of the machinery.
Environmental Considerations
The environment in which most machines operate is hard on electronic equipment. The CAESbasic system is designed to operate in this type of environment, but when installing the equipment consider the following:
- Shock and Vibration
- Temperature
- Dust
- Water
The following sections describe how to manage these environmental conditions to extend the life of the equipment.
Shock and Vibration
To reduce shock and vibration of the system do the following:
- Fix the equipment firmly and leave no room for movement or rattling.
- Fix the provided mounts directly to a structural part of the machine.
- Use the shortest possible length for all brackets. Long brackets introduce more vibration than short ones.
Some CAESbasic parts incorporate shock-mount assemblies into the brackets.
Temperature
Avoid extremes of temperature where possible. Mount the MS840 GPS receiver in a cool area. This does not apply if you work in subzero temperatures. The TC900B data radios also need good air circulation to cool efficiently.
Dust
Dust is present in all mining environments. The components in the CAESbasic system are sealed to exclude dust. However, you should also take the preventative measures that follow:
- Place dust caps on unused connectors
- Try to keep the connectors clean when you attach the cables
- Keep the screen clean
Note: Use a moist cloth or wet-wipe to clean the display screen. Do not use your fingers. If you use your fingers you will scratch the screen.
Water
The CAESbasic components are sealed to prevent water getting into them. However, you must take care when selecting mounting locations.
Potential sources of water include, but are not limited to the following:
- Condensation
- Rain
- Snow
- Ground water thrown up by passing vehicles or wheels
- Vehicle-washing systems such as waterblasters
Machine Installation
Before you mount the equipment, lay out the harnesses to make sure that all the cable connectors reach the connectors fitted to the machine.

Main and Power Cable Harnesses
The CAESbasic system cable harnesses consist of the following:
- Main harness (between the MS840 GPS receiver and CD550 display)
- Power harness (from the main harness to the machine's power)
- Fuse holder (with 10 amp fuse)
When you are routing the cable harness do the following:
- Ensure that the cables cannot interfere with or catch on any mechanical linkages.
- Route the cables so that the cables do not prevent access to any service maintenance panels.
- Protect the cables where they pass over or through any sharp metal edges.
- Secure the cable with cable ties and silicone. This prevents the cable from moving and chafing.
- Use cable ties to secure the cable to something solid near each connector. This reduces stress on the connector.
- Do not tie the cable to machine parts that get hot.
- Make sure that the fuse holder (and fuse) is accessible.
- Make sure that the cable is long enough to reach all of the system components.
Note: Use string or wire to route along the anticipated installation path. Measure this against the cable harness to make sure that the cable is long enough.
Caterpillar recommends that you connect the CAESbasic system to an ignition-switched power source, such as the machine's run relay. This ensures that the system will not drain the machine's battery when the system is not in use.
Caterpillar also recommends that you install the fuse holder assembly in a suitable location in the operator's cab, and wire the holder into the pink wire of the power cable harness.
To wire the CAESbasic system to the run relay proceed through the following steps:
- Locate the run relay.
- Identify which terminal on the run relay is the main feed from the batteries, and which terminal is turned on and off by the ignition key.
- Turn the ignition and the master disconnect switch to the OFF position.
- Route the power cable harness to the run relay and secure the harness in place.
- Connect the pink wire to the switched terminal on the run relay.
- Connect the black wire to a suitable grounding lug on the chassis.
- Verify that all wire connections are correct and tight.
- Turn the key switch and the master disconnect switch to the ON position.
Illustration 17 shows the wiring diagram for the run relay connections.
Illustration 17 | g00989451 |
Machine run relay connections |
NOTICE |
---|
If the run relay is not accessible, you can connect the power cable harness directly to the ignition switch of the machine. However, make sure that the CAESbasic system power requirements do not exceed the specifications of the ignition switch, or the ignition circuit will be overloaded. Refer to ""Technical Specifications" " for more information. |

GPS Antenna Cable
Note: Do not cut off any cabling that is not used. Bundle, tie wrap and store any extra cabling in a convenient place. Cutting the cable can affect the performance of your cabling system.
Route the GPS antenna cable from the GPS antenna to the MS840 GPS receiver.
Note: Make sure that there are no kinks or sharp bends in the antenna cable. Kinks and sharp bends reduce the performance of the GPS receiver.
Radio Cable
Note: Do not cut off any cabling that is not used. Bundle, tie wrap, and store any extra cabling in a convenient place.
Route the radio cable from the data radio to the MS840 GPS receiver. When routing the radio cable do the following:
- Make sure that the cable is protected from mechanical damage.
- Route the cable so that the cable does not prevent access to any service maintenance panels.
- Protect the cable where the cable passes over any sharp metal edges.
- Secure the cable with cable ties and silicone. This prevents the cable from moving and chafing through.
- Secure the cable near each connector. This reduces strain on the connector.
- If possible, secure the radio cable to other wiring running up the interior surface of the ROPS.
- Avoid heat.
When connecting the TC900B radio cable to the MS840 GPS receiver, connect the right angle connector end to the GPS receiver and the straight connector to the TC900B data radio.
Note: If the cable is routed up the outside of the machine cab, you can easily attach the cable by running a bead of RTV silicone along the window-sealing rubber, and pressing the cable into the silicone. Make sure the cable is firmly fastened at both ends.
Measurements
This section describes techniques for measuring the blade and antenna dimensions. A track-type tractor is used to show the techniques. However, the blade and antenna measurement requirements are the same for all eleven machine types supported by the CAESbasic system. The measuring techniques include the following:
- Machine and blade alignment
- Calculating GPS antenna to blade offsets
The values obtained are entered into the "Machine Dimensions" dialog in the system. Refer to Service Manual, RENR7886, "CAESbasic Reference Manual", "Setting the Machine Dimensions" for more information.
To make these measurements, you need the following:
- A plumb bob and string
- A step ladder
- A steel framing square
- A steel tape or rule
- A carpenter level
- A straight edge
- Clamps
Note: Make the measurements again if the blade or tracks are replaced.
Machine and Blade Alignment
To position the machine to make the measurements proceed through the following steps:
- Park the machine on flat and level ground.
- Position the blade so that the blade is level and touching the ground.
- Make the measurements.
Measuring Ground Plane Height
To measure the vertical distance from the bottom of the GPS antenna ground plane to the cutting edge of the blade proceed through the following steps:
- Place a straight edge across the roof of the cab. Ensure that the straight edge is perpendicular to the centerline of the machine.
- To hold the straight edge steady, clamp the straight edge in position.
- Measure the height from the bottom of the GPS antenna ground plane to the top of the straight edge. This is shown as Height A (14) in illustration 19.
- Calculate the ground plane height.
Ground plane height = Height A + Height B.
Illustration 19 | g00989476 |

- Enter this value into the "Ground plane height" field in the "Machine Dimensions" dialog.
Refer to Service Manual, RENR7886, "CAESbasic Reference Manual", "Setting the Machine Dimensions" for more information.
Measuring GPS Antenna Back From Cutting Edge
The GPS antenna in the CAESbasic system is mounted on the cab of the machine. Depending on your machine type, the GPS antenna mount is behind or in front of the cutting edge.
If the GPS antenna is mounted behind the cutting edge enter a positive value for the "Antenna back from cutting edge" field in the "Machine Dimensions" dialog.
If the GPS antenna is in front of the cutting edge enter a negative value for the "Antenna back from cutting edge" field in the "Machine Dimensions" dialog.
GPS Antenna Is behind the Cutting Edge
When the antenna is behind the cutting edge such as on a track-type tractor, motor grader, or wheel loader use the following instructions.
In order to measure the horizontal distance parallel to the machine's centerline from the center of the GPS antenna to the cutting edge of the blade, proceed through the following steps:
- Secure the plumb bob to the front of the straight edge so that the plumb bob hangs down to the ground and is in line with the left blade tip.
- Measure the distance from the blade cutting edge to the plumb bob, parallel to the centerline. This is shown as distance C (17) in illustration 20.
- Measure the distance from the center of the GPS antenna to the front of the straight edge, parallel to the centerline. This is shown as distance D (18) in illustration 20.
- If the straight edge is in front of the GPS antenna use the following equation:
Antenna back from cutting edge = Distance C + Distance D
If the straight edge is behind the GPS antenna use the following equation:
Antenna back from cutting edge = Distance C - Distance D
- Enter this positive value into the "Antenna back from cutting edge" field in the "Machine Dimensions" dialog.
Refer to Service Manual, RENR7886, "CAESbasic Reference Manual", "Setting the Machine Dimensions" for more information.

When the GPS antenna is in front of the cutting edge such as on a wheel tractor-scraper use the following instructions.
To measure the horizontal distance parallel to the machine's centerline from the center of the GPS antenna to the cutting edge of the blade, proceed through the following steps:
- Secure the plumb bob to the front of the straight edge so that the plumb bob hangs down to the ground and is in line with the left blade tip.
- Measure the distance from the blade cutting edge to the plumb bob parallel to the centerline. This is shown as distance E (24) in illustration 21.
- Measure the distance from the center of the GPS antenna to the front of the straight edge parallel to the centerline. This is shown as distance F (23) in illustration 21.
- If the straight edge is in front of the GPS antenna use the following equation:
Antenna back from cutting edge = Distance E - Distance F
If the straight edge is behind the GPS antenna use the following equation:
Antenna back from cutting edge = Distance E + Distance F
- Enter this value into the "Antenna back from cutting edge" field in the" Machine Dimensions" dialog.
Note: This value will be negative.
