the top dresser and allow the trucks hydraulics to cool
down. If the sensor has failed, it will not keep the top
dresser’s hydraulics from operating - the sensor only
monitors the fluid temperature level coming from the
truck.
Refer to the “Electrical System” section in this manual
for more information on the sensor.
The temperature sensor does not have any user
serviceable parts. If the sensor has failed, it will need
replacement.
LEFT AND RIGHT HAND SPINNER WHEEL
HYDRAULIC MOTORS
Hydraulic power to the spinner motors is controlled at
the manifold valve block by solenoid valve PF1 and
exits the upper section of the manifold block at port
“CF”. The speed of the motor is controlled by the PF1
valve. ON/OFF activation and spinner speed settings
(%) for PF1 are controlled at the electronic control
box.
The controlled flow from the manifold block (port CF) is
sent to the left hand motor port “A”. Flow leaves the left
hand motor through port “B” and enters the right hand
motor at port “B”. Flow out of the right hand motor
returns to the lower section of the manifold block at
port “IN” to power the conveyor belt motor.
The direction of rotation of the motors is opposite
from each other. The right hand spinner wheel rotates
counterclockwise, the left hand spinner wheel rotates
clockwise (as viewed from above the WideSpin 1540
TEC). The spinner wheels are a direct drive from the
hydraulic motors.
If the spinner or the spinner motors fail to operate,
check the following:
● Check the CAN receiver and the electronic control
box for error codes.
● Quick-disconnects not attached. Check one at port
“IN” on the lower section of the manifold valve block
and one on the hose connected to the left hand
spinner motor at port “A”.
● Spinner Speed set too low at electronic control
box.
● Bad electrical connection with the truck.
● Bad electrical connection at manifold block PF1
solenoid coil.
● Trucks throttle and/or governor set too low to provide
adequate engine RPM and hydraulic flow.
● Trucks hydraulic flow selector on wrong setting.
