Fault
Cause
Remedy
The temperature of the hydraulic
fluid is too high in a tractor
equipped with a constant pres-
sure system (some older John
Deere tractors)
The system converting bolt on
the spreader valve block has not
been screwed in to the limit stop
(opposite of factory setting).
Screw the system converting bolt
on the spreader valve block until
to reaches the limit stop
Defective plug couplings
Check plug couplings, re-
pair/replace as required.
Defective tractor control unit
Check tractor control unit, re-
pair/replace as required.
The temperature of the hydraulic
fluid is too high for a tractor with
load-sensing system and oil re-
moval via the tractor control unit
The system converting bolt on
the spreader valve block has not
been unscrewed to the limit stop
(factory setting).
Unscrew the system converting
bolt on the spreader valve block
until it reaches the limit stop.
The quantity of oil at the tractor
control unit has not sufficiently
reduced.
Reduce the quantity of oil at the
tractor control unit.
Defective plug couplings
Check plug couplings, re-
pair/replace as required.
Defective tractor control unit
Check tractor control unit, re-
pair/replace as required.
The temperature of the hydraulic
fluid is too high for a tractor with
load-sensing system, direct oil
removal and control line
The system converting bolt on
the spreader valve block has not
been screwed in to the limit stop
(opposite of factory setting).
Screw the system converting bolt
on the spreader valve block until
to reaches the limit stop
Defective plug couplings
Check plug couplings, re-
pair/replace as required.
AMATRON 3
shows no
function
Power supply defective.
Check power supply to
AMATRON
+
A warning signal is given on the
control terminal
See help key control terminal
Sensor provides incorrect speed
information to the control terminal
Check sensor distance (approx.
1 –4 mm) on both hydraulic mo-
tors. For this purpose, rotate both
spreading discs fully with hydrau-
lic system deactivated. At each of
the 4 contacts the speed sensor
must switch on and off. When
switched on, the LED on the rear
of the sensor beside the cable
entry lights up.
Spreading discs do not start to
rotate when they are switched on
via the control terminal
Button for switching on spreading
disc drive not pressed for min. 3
seconds (safety function).
Press button for switching on
spreading disc drive for min. 3
seconds.
Fluid supply from tractor is not
switched on.
Switch on fluid supply from trac-
tor.
