Flow Gates. Two flow gates are located on the
front engine compartment bulkhead. Position of the flow
gates control the amount of paving material that passes
from the hopper to the screed. The flow gates are
raised and lowered by separate +12 volt DC actuators.
The actuators can be run from the operator switch panel
or from the screed control panels.
1.12.2. Valve Panel Compartment. The valve panel
compartment is located behind the engine compartment.
The hydraulic oil reservoir and fuel tank are located
underneath the valve panel. Major paving machine
components found in the compartment are as follows:
Valve Panel. The valve panel is the mounting
location for all major control valves for the propulsion
system, auger/ conveyor system, tow point control
system, vibration system, stack valve, and major system
Diagnostic Connector Assembly (DCA) Box and
Connector. The paving machine is equipped with
STE/ICER transmitters to monitor machine systems.
Wiring from the transmitters is routed to the DCA
connector in the DCA box. The DCA connector provides
the interface for hookup and operation of a STE/ICE-R
