pump speed can be adjusted using the up and down arrows.
Circulate for a minimum of 15 minutes at a high flow rate.
3.
Verify valve actuator (open & closed) positions using the diagram
in Appendix 2: Pump group flow paths (page 125).
Spray Auto
1.
Install clean spray nozzles of the appropriate nozzle opening for
the application rate and paving speed of the job.
2.
Activate the
Spray Auto
pump function and verify proper
operation. The spray nozzles will not spray until the master spray
switch on the pendant is turned on.
If the master spray switch is off and the Spray Auto pump
function is active, the small asphalt pump will run at a
constant flow rate of 10 gpm.
With the master spray switch on, the small asphalt pump
speed is regulated to supply the application rate based on
the vehicle speed and the selected spray width. If the
vehicle is not moving, the flow rate from the asphalt pump
will be reduced to zero.
3.
Verify valve actuator (open & closed) positions using the diagram
in Appendix 2: Pump group flow paths (page 126).
4.
Verify all spray nozzle actuators function properly (observe them
open and close), by turning them on and off with the navigation
arrow and the OK button on the Sprayer Selection
screen.
Spray Bar Vacuum
1.
With the paver engine running at high idle (full speed), activate
the Spray Bar Vacuum pump function. Verify both the large and
small asphalt pump shafts are rotating.
2.
Verify valve actuator (open & closed) positions using the diagram
in Appendix 2: Pump group flow paths (page 127).
