1. PCS400 Quiz Phil Jackson Training Manager May 2009

2. 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!!!

3. Paver Role What is the role of the paver? To meet specifications for grade, texture & smoothness

4. Screed Name 4 Factors that affect the Screed Paving speed Head of material Screed adjustments Mix design Mix temperature Air temperature Grade (base) temperature

5. Material Head With respect to the level of the auger, how deep should the material be? Half the depth of the auger.

6. Sensors Name four sensors you can use with AccuGrade CD620 AS200 ST200 CS200 Averaging Ski 3D system

7. 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

8. 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

9. 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

10. CS200 – Contact Sensor What 2 modes can the CS200 operate in? Ski (shown) String line sensor

11. 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

12. Sensor Position Can the sensor position affect the quality of the surface? Yes

13. Position at the Front Why would you position the sensor near the front of the tow arm? Smooth surface

14. 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)

15. Brackets What is the advantage of the 5 part bracket? Flexible sensor positions

16. CAN Terminators Are the CAN terminators Active of Passive? Active on the 125K CAN bus

17. Displays How many displays can you have in one system? One or Two

18. 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

19. Hidden Menu What is the menu that requires a triple key press to get into? Installation menu

20. 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

21. 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)

22. Password What is the password to unlock a locked menu? 8024 – Postal (zip) Code for the Trimble New Zealand office in Christchurch

23. Runtime icons Name the icon that is always at the top of the paving screen Paving Screed
