Rosco Maximizer 2B Asphalt Distributor 4-3
Specifications
Burner System
USE BURNERS PROPERLY! Burners are used to
increase the temperature of liquid asphalt material to
the correct spraying temperatures. The burners should
only be used while the liquid asphalt material is being
circulated in the tank .
If the material has cooled to the point
that it will not flow easily and will not circulate, the
operator must use extra care. Improper heating will
cause damage to the equipment and the material
being heated.
The burners in the Maximizer 2B have a very high
heat output which must be dissipated through the
asphalt . Asphalt is an excellent insulator and resists the
conduction of heat through the material .
If the material is heated too hot or too quickly without
the proper circulation, hot spots will be created near the
rear of the tank at the flue tubes. This will damage the
flue tubes and cause a break down of the material.
Operating the burners without
circulating the product can create explosive fumes.
If the product can not be circulated after 15 minutes
of heating, the fuel to the burners must be turned off,
while leaving the blowers running. Do not try to heat
material again for 30 minutes.
If it is necessary to heat asphalt that has cooled more
than 20 to 30 degrees below the optimum spraying
temperature, the operator must use extreme care in
reheating the material .
Run the burners for short periods of
time (15 minutes ON, 15 minutes OFF) to allow the
heat to dissipate through the material. This will
prevent damage to the flue liner.
The amount of time necessary to heat the asphalt
material to allow proper circulation and heating will
vary depending on the type of material, the type of
burners, the tank size and the amount of material in the
tank . If you have any doubts about the proper way to
heat cooled asphalt, contact your asphalt supplier or
equipment manufacturer.
The Burners are located at the left rear of the Maximizer
2B. The flame from the burner is directed through
the fire tubes along the bottom of the tank. Diesel or
propane can be used as fuel in accordance to the
burner option specified.
Never operate the burners without first reviewing the
instructions .
Plus One Controller
The Plus One system is used to automatically control
the application rate of the asphalt distributor truck . It is
capable of automatically maintaining constant asphalt
application rates regardless of changes in distributor
speed and spraybar width. The controller has on/off
toggle switches to provide spray nozzle control along
the spraybar in 1 foot ( .3 m) increments .
Distributor functions are set by selecting one of eight
modes of operation. Each mode of operation defines
the behavior of the automatic asphalt valves and the
spraybar valves for the distributor function selected . A
software memory feature is included to store up to 12
user defined presets of operating parameters for quick
setup of application rates and speed calibrations .
Selectable readouts on the in-cab control panel display
the following in real time; distributor ground speed fpm
(mpm), asphalt spray rate gpm (Lpm), total distance
sprayed ft (m), total gallons sprayed gal (Lit), total
area sprayed sq.yd. (sq.m), flow & speed calibration
application rate gal/sq.yd. (L/sq.m), tank temperature
degree F (C), hour meter hr, and spraybar length ft (m) .
The controller uses either a GPS Speed Sensor or
an (optional) Radar Horn Speed Sensor to measure
distributor ground speed necessary for application rate
calculations and real time display of distributor metrics .
Rear controls are located in the tool box on the right
hand side rear fender and are used to control asphalt
pump speed, asphalt pump direction, spraybar hydraulic
functions and the optional washdown pump when rear
control priority is selected .
In-Cab Operator System
The main console located in the truck cab contains a
DP610 color display and utilizes a toggle switch system
for Maximizer 2B spraybar control. Truck control
parameters and modes of operation are selected
through the DP610 display using programmable soft
keys . Setup functions and real time monitoring functions
are stored and processed in the DP610 .
In addition, the console includes a Master Power ON/
OFF toggle switch, Burner switch, and potentiometer for
the control of asphalt pump speed and direction when
in MANUAL mode and front control priority. Parameters
are used to configure options installed on specific trucks
as well as increase memory and data storage capacity .
A CAN signal allows communication between the In-Cab
Controller and the control modules located in the valve
box at the rear of the truck .
