FJDynamics AT2 Auto Steer System Hardware Installation Manual
1 Product Introduction
2 Preparation Before Installation
FJDynamics AT2 Auto Steer System is an autosteering system that is launched by
FJDynamics for agricultural machinery and supports assisted straight line driving. The
system consists of the control terminal, GNSS receiver, electric steering wheel, and wiring
harnesses. The control terminal runs the software developed by FJDynamics.
Before installation, read the safety advice in this manual carefully to avoid doing harm to
people and equipment.
Note that the following safety advice cannot cover all possible dangerous situations.
•Do not install and commission the equipment in environments with high temperature,
heavy dust, harmful gases, ammables, explosives, electromagnetic interference (for
example, around large radar stations, transmitting stations, and substations), unstable
voltages, great vibration, and strong noise.
•Do not install the equipment in places where water is likely to accumulate, seep, drip,
and condense; otherwise, the equipment ports could be damaged.
2.1 Safety Instructions
2.1.1 Installation

FJDynamics AT2 Auto Steer System Hardware Installation Manual
To ensure the normal operation of the equipment, the installation site must meet the
following requirements.
•Ensure that the installation position is rm enough to support the equipment and its
accessories.
•Ensure that there is enough space to install the equipment at the installation position,
without any obstruction or obstacle.
• The temperature and humidity of the working environment should be kept within a
reasonable range to ensure the normal operation and service life of the equipment.
Avoid high temperature and humidity. In summer, protect the control terminal from direct
sunlight, and note that appropriate space must be maintained between the shelter and
the control terminal.
• The equipment will be damaged if it works under improper environmental temperature
and humidity.
• When the relative humidity is too high, insulating materials may not perform well,
causing leakage currents. Mechanical property changes, rusting, and corrosion may also
occur.
• When the relative humidity is too low, insulating materials will dry and contract, and
static electricity may occur and damage the electric circuits of the equipment.
•To avoid accidental damage, do not frequently disassemble the equipment after
installation.
•Before disassembly, turn off all power supplies and disconnect the cable from the battery
to prevent equipment damage.
•Electrical operations must be performed by qualied personnel in accordance with local
laws and regulations.
•Carefully check the working area for potential hazards, such as wet ground.
•Before installation, learn about the position of the emergency stop button. Use this button
to cut off the power supply in case of accidents.
•Do not put the equipment in a humid place. Prevent the liquids from entering the
equipment.
•Stay away from radio transmitting stations, radar stations, high-frequency and large-
current equipment, and other high-power radio equipment.
•Direct or indirect contact with high voltage or utility power may cause death.

2.2.3 Air
2.2.4 Power Supply
•Ensure that the contents of salt, acid, and sulfide in the air are within a reasonable range.
Some hazardous substances will accelerate the rusting and corrosion of metals and the
aging of parts. Keep the working environment free of harmful gases (for example, sulfur
dioxide, hydrogen sulfide, nitrogen dioxide, and chlorine).
• Input voltage: The system supports the input voltage of 9-36 V.
• Ensure that the power line is connected properly to the positive and negative terminals
of the battery. Keep wiring harnesses away from hot objects.
Prepare the following tools before installation.
