HOPPER SPREADERS: THEORY OF OPERATION
STEEL / POLY HOPPER SPREADERS (ELECTRIC MODELS)
The spreader is controlled by a FLEET FLEX
multiplex electrical system. Using a digital signal,
the control sends inputs to the spreader module
which controls the conveyor and spinner speed
independently. The module, in turn, monitors
amperage draw and will display any fault codes on
the control display screen.
Examples:
(
EH
) Empty Hopper,
(
CE
) Communication Error.
The control also gives the operator the ability to
adjust the brightness level of the LED lights, and to
calibrate the empty hopper setting.
NOTE: Calibrating the empty hopper setting
should be part of the set-up procedure, and
must be calibrated when the spreader is
empty. Failure to do so will result in a false
code or no code when the spreader has run
out of material.
Digital signals are sent from the control, passing
through the two communication wires in the vehicle
control harness to the vehicle harness assembly
(power cable with two communication lines), which
also provides 12V DC and ground to the spreader.
From there, it travels down the vehicle harness to
the hopper harness assembly into the spreader
module. Not only are the spreader conveyor and
spinner speeds set, but so are accessories, such
as vibrator, work lights, strobe lights, and the
ON/OFF control of pre-wet systems.
The
vehicle control harness
also contains the
red switched accessory wire and the orange
Center High Mounted Stop Light (CHMSL) wire.
NOTE: Not all vehicles will connect the
CHMSL wire in the cab. Some may need to be
connected at the rear of the vehicle. Check the
body builder's guide pertaining to the make of
the vehicle.
The vehicle harness contains wiring for the license
plate light and CHMSL light.
NOTE: Not all vehicles will connect at the rear
of the vehicle. Some may need to be connected
in the cab. Check the body builder's guide
pertaining to the make of the vehicle.
See the Owner's Manual and Installation Instructions for more complete information.
