I. Introduction
FJD 3D Excavator Guidance System is a rear-mounted excavator guidance system, which adopts Beidou
high-precision real-time dynamic positioning technology. It gets the real-time precise 3D position
information of the bucket by reading attitude sensors installed on the excavator and calculating the
calibrated main pivot sizes. The current cut-and-fill workload is displayed in real time in coordination
with the work tasks generated by the self-designed transformation software to complete the goal of
digitally guided excavation and construction. The bucket is able to complete the work accurately even
in blind areas with poor eyesight, completely changing people's understanding of the traditional
construction method of excavators. This system is composed of RTK high-precision positioning
equipment, data communication equipment, and on-board tablet computer (display equipment),
attitude transducers, communication antennas, and harnesses. The on-board tablet computer is
equipped with an excavator guidance software independently developed by FJD, namely FJD 3D
Excavator Guidance System, which makes real-time statistics of the excavation depth, slope, elevation,
and satellite positioning of the current operating equipment.

2. Preparation before Installation
2.1 Safety Instruction
In order to avoid harm to people and equipment, please read the safety recommendations herein
carefully before installation.
Note: Not all risks are covered by the following safety recommendations.
Installation Safety
1. Don’t install this system in an environment susceptible to electromagnetic interference (large radar
stations, transmitting stations, substations) which features high temperature, much dust, harmful gas,
flammable and explosive articles, unstable voltage, much vibration or strong noise, as this
environment is not conducive to the operation of the equipment.

2. Don’t install the equipment in places where water accumulation, water seepage, dripping, and
moisture condensation most likely happen.
3. Install or remove the equipment as described in the hardware installation manual.
Removal Safety
1. Once installed, don’t frequently remove the equipment to avoid damages.
2. Turn off all power supplies and disconnect all power lines and cables before removal.
Electrical Safety
1. The local laws and regulations must be observed during electrical operations. The relevant
personnel must be qualified.
2. Please carefully check for potential hazards in the work area, for example, wet ground.
3. Before installation, be familiar with the location of the emergency power switch and turn off the
power switch first in the event of an accident.
4. Check carefully when it is necessary to turn off the power.
5. Do not put the equipment in a humid place, and no liquid is allowed to enter the equipment.
6. Keep away from wireless transmitting stations, radar transmitting stations, high-frequency and
high-current equipment, microwave ovens, and other high-power wireless equipment.
7. Direct or indirect contact with high voltage or mains power through wet objects may cause fatal
danger.
8. Irregular and incorrect electrical operations may cause accidents such as fire or electric shock, and
even cause serious and fatal harm to the human body and equipment.
2.2 Requirements for Installation Site
To ensure the normal operation of the equipment and prolong its service life, the installation site is
required to meet the following standards.
Installation Location Requirements
1. Install the equipment in an open environment, and ensure that the closed environment where the
equipment is installed has a good ventilation and cooling system.
2.Ensure that the equipment is installed at a position firm enough to support the weight of control
terminal and accessories.
3. Ensure that the installation location is suitable for the size of control terminal, with some space left

around to facilitate heat dissipation.
Temperature and Humidity Requirements
1. To ensure the normal operation and the service life of the equipment, temperature and humidity
in the operating environment should be up to standard.
2. Long-term operation in an environment that does not meet the temperature and humidity
requirements will cause damage to the equipment.
3. Operation in an environment with high relative humidity is most likely to cause poor insulation of
the insulating material and even leakage. Sometimes, changes in the mechanical properties of
materials and corrosion of metal parts are also prone to occur.
4. Operation in an environment with low relative humidity will cause the insulating sheet to dry and
shrink, and meanwhile, most likely generate static electricity, which will harm the circuits in the
equipment.
5. Operation in an environment with excessively high temperature will be more harmful and will
greatly reduce the reliability of the equipment. The long-term high temperature will also affect the
service life and accelerate aging.
Cleanliness Requirements
For the environment where the equipment is located, there are strict requirements on the salt, acid,
and sulfide contained in the air. Some harmful substances will accelerate the corrosion of metals and
the aging of certain parts. Intrusion of harmful gases (sulfur dioxide, hydrogen sulfide, nitrogen dioxide,
chlorine, etc.) should be avoided.
Power Requirements
Kit voltage input:
1.The input voltage should be within the range of 12±1V; a lower input voltage is allowed, but it will
affect the accuracy.
2.The input voltage should be within the range of 24±1.5V. The impact on accuracy will be reduced
after the excavator is started.
