Rosco Maximizer 2B Asphalt Distributor 5-7
Component Location
Table 5-2. Main In-Cab Control Panel
ITEM NO CONTROL NAME FUNCTION
1 Master Control Master On/Off switch for the control panel . The panel must be turned on
before the distributor can operate .
2 Burner Control Switch The master On/Off control for the burners . Burners will only operate if the
distributor is travelling less than 5 mph and the burner temperature is less
than the high temperature limit set point .
NOTE: Burner Control switch is a momentary switch and will return to the
OFF position automatically . Once the switch is pressed to the ON position,
the Rear Burner Controls (Figure 6-7) can be activated . Do not operate
burners longer than 15 minutes at a time .
3 Manual Pump Speed
Control Controls the GPM and direction of the asphalt pump when the Auto/Manual
operation mode is set to MANUAL and the Front/Rear Priority Pump Control
is set to FRONT, (Figure 5-5,2,3) .
4 Spraybar Master This is the master control switch for all of the nozzles on the spraybar . When
turned ON, all individual Spraybar Segments will spray asphalt unless the
individual spraybar switches (Figure 5-2,5,6,9,10) are turned OFF or the
individual valve actuators on the spraybar are mechanically disengaged .
This switch has three positions:
1 . BAR CRCLT (Up): Used in conjunction with the AUTO setting and the
Mode Selection ( Spray or Bar Circulate) to allow the controller to
circulate asphalt in the bar. Flow rate is defined in the Flow Calibration
screen during setup .
2 . OFF (Center): Can be used to build pressure in the bar for starting or
when spraying a heavy application .
NOTE: If the switch is left in the OFF position, excessive pressure (70 psi)
can build in the spraybar resulting in too much asphalt being applied
at the start of the spray run . For the most positive results when
starting to spray, leave the switch in the BAR CRCLT position before
switching to ON .
3 . SPRAY (Down): With all other settings as indicated for Spraybar
Circulate, this is the normal operating position for spraying . The SPRAY
position opens all spraybar valves that are mechanically engaged and
activated .
NOTE: There is a magnetic switch mounted on both spraybar wings which
prevents spraying from the wings when the wings are vertically
folded .
5 1 ft . Spray Nozzle
Activation - Left Bar There are six 1 ft . spray nozzle activation switches on the control panel
corresponding to the nozzles on the left 6 ft . of spraybar . These switches
are positioned on the In-Cab Control Box in relationship to the 1 foot
sections along that 6 ft . length of the spraybar . Once activated (switch
down); the nozzles will spray asphalt when the Spraybar Master Switch
(Figure 5-2,4) is moved to the SPRAY position .
