Screed Reaction
• How far, in “tow arm” lengths does the screed have to travel before an elevation change is completed?
• A 5
• The point here is don’t get too button happy raising and lowering the screed to reach the target thickness. Let the screed settle out!!!
Paver Role
• What is the role of the paver?• To meet specifications for grade, texture &
smoothness
Screed
• Name 4 Factors that affect the Screed• Paving speed• Head of material• Screed adjustments• Mix design• Mix temperature• Air temperature• Grade (base) temperature
Material Head
• With respect to the level of the auger, how deep should the material be?
• Half the depth of the auger.
Sensors
• Name four sensors you can use with AccuGrade CD620
• AS200• ST200• CS200• Averaging Ski• 3D system
AS200 – Angle Sensor
• What are the two main environmental conditions you find on a paver that the AS200 is designed to handle?
• Designed to cope with the vibrations and the high temperatures on the screed
ST200 – Sonic Tracer
• What are the transducers in the ST200 made of?
• Ceramic• Why is this good?• Very Robust and resistant to heat and
contaminants• Which other type of transducer are they
more robust than?• Foil
ST200 – Sonic Tracer
• Name advantages of the ST200 over competitive sonic tracers
• Ceramic Transducers – robust
• 5 elevation transducers – mini averaging ski
• Environmentally sealed• Horizontal Temperature Bail – will not get lost or bent
• Offline guidance to a Sting Line
CS200 – Contact Sensor
• What 2 modes can the CS200 operate in? • Ski (shown)• String line sensor
Averaging Ski• What would you use to average a large length of existing surface for guidance? • Averaging Beam
• How can you get maximum smoothness from the Averaging Ski?• Orient rear sensor over fresh mat
Sensor Position
• Can the sensor position affect the quality of the surface?
• Yes
Position at the Front
• Why would you position the sensor near the front of the tow arm?
• Smooth surface
Position at the Rear
• Why would you position the sensor near the rear of the tow arm?
• Good thickness control (usually called Joint Match, the point is quick screed response)
Brackets
• What is the advantage of the 5 part bracket?
• Flexible sensor positions
CAN Terminators
• Are the CAN terminators Active of Passive?
• Active on the 125K CAN bus
Displays
• How many displays can you have in one system?
• One or Two
Home, Auto/Manual,Elevation select • What do these three icons do?
• This is a bit of a trick question. 2 of these have 2 functions depending if you hold or tap them
• Home– Tap: Toggles between any menu screen and runtime screen– Hold: Same
• Auto/Manual– Tap: Toggles system between manual and automatic control – Hold: Puts the system in measure mode
• Elevation select– Tap: Edit the elevation run time / Calibrate Slope Sensor – Hold: Swaps control between elevation and slope mode
Hidden Menu
• What is the menu that requires a triple key press to get into?
• Installation menu
Hidden Installation Menu
• What are the key presses to get into this menu
• To enter the Installation menu you start in the Configuration menu and:– press + hold left bottom
button– press + hold right down
arrow– press + release second from
bottom button on right
Language Selection
• What are the key presses to get Directly into the Language menu
• Hold left and right bottom buttons, then apply power– Use Display Connector for Power
+ (Power)
Password
• What is the password to unlock a locked menu?
• 8024– Postal (zip) Code for the Trimble New Zealand
office in Christchurch
Runtime icons
• Name the icon that is always at the top of the paving screen
• Paving Screed
