Components for AC---III system
(see figure 1 on previous page)
A. Sensor for outdoor temperature
Sensor (B10C) is fitted under the fixing screw for the head-
light. AC---III display shows the outdoor temperature.
B. Sensor for engine coolant temperature
Sensor (B9C) controls the cold starting automatics. An indica-
tor light on the instrument panel shows when the engine can
be started. The system controls automatically the afterglow-
ing in cold conditions. AC--- III display shows also the engine
coolant temperature.
C. Sensor for front wheel steering angle
Sensor (S4C) notifies the AC---III system when the font wheel
steering angle is over ±10˚. Then the automatics disengage
the differential lock. The lock is re--- engaged automatically
when the front wheels are turned less than ±10˚
D. Potentiometer on fuel injection pump
Potentiometer (B8C) notifies the system the position of the
governor control lever on the fuel injection pump. AC---III
compares the governor control lever position and the engine
revs. Eg. the system changes automatically to the lower gear
when the engine revs drop during a hard load (and vice versa)
1) Grease
2) Locking fluid Loctite 242
E. Sensor for engine revs
Sensor (B4C) is fitted on the gearbox under the cab. The sen-
sor measures the engine rotation speed from the gear for the
hydraulic pump drive mechanism. The display shows also the
engine revs. The sensor controls the engagement of the
quick---shift gears and indicates if the PTO clutch is slipping.
F. Sensor for rear axle rotation speed
Sensor (B1C) measures the rotation speed of the RH side rear
axle from the impulse disc fitted on the final drive planetary
gear. Engages the differential lock when the rotation speed
difference between the rear axles exceeds 25 %.
G. Display unit
Function keys on the display unit (A3C) have been presented
on pages 340/6 ---7. Below the display unit there are switches
for selecting between the manual or automatic control of the
tractor transmission.
H. Sockets at the rear of the tractor
Socket X12C (for connecting implement sensors to the AC---III
system)
PTO emergency stop socket X13 C (terminator)
I. Central processing unit ECS (Electrical Control
System
)
The central unit ECS (A1C, A2C) is fitted in the lever console
in the cab. On the ECS is fitted a sticker with the tractor manu-
facturing number etc.
J. Sensor for PTO revs
Sensor (B3C) measures the rotation speed of the PTO shaft
from the impulse disc fitted on the shaft. Display shows the
PTO rotation speed.
K. Radar
Radar (B7C) notifies the ECS the actual tractor travelling
speed. The radar is used e.g. for detecting the wheel slip. The
radar has been connected to the hydraulic power lift so that
when the set slip percent is exceeded the lift order is sent to
the power lift. The radar controls also the engagement of the
front wheel drive and the differential lock.
Radar --- You are not allowed to go under the tractor
which has radar (slip control models) before the current
switch has been turned off. --- dangerous for eyes.
L. Rotation speed sensors for front axle and
gearbox
Sensors (B2C and B5C) are fitted on the front face of the re-
verse shuttle. The gearbox speed sensor measures the bevel
pinion shaft rotation speed from the impulse disc at the front
end of the shaft. The front axle rotation speed is measured
from the impulse disc which is fitted on the output shaft to the
front axle.
