3D Paving Training Start Procedure & UTS Handover Procedure Phil Jackson Training Manager March 2010

Before you Start

Before You Start  Check you survey marks are present and accurate  Check your UTSs have the correct firmware and pass all calibration tests –Especially if they have travelled  Check your TDC2 has the correct SCS900 version, sites and designs –Check your Grade Check Pole Bubble

Paver – UTS Handover Procedure Before you start

SCS – UTS Handover Procedure  Can be complicated & difficult  Or can be simple  It depends on your procedures

Pitfalls  If 2 or more UTS have a machine with the same Channel and Network ID, then the radios will interfere and neither will be heard  Two UTS are trying to talk to the same machine at the same time

SCS – UTS Handover Rule  Assign a Channel to each Machine or Grade Checker  Assign a Network ID to each UTS

SCS – UTS Handover Procedure  First for one paver  Next for 2 pavers

Channel = Machine  Assign a Channel to each Machine  Paver 1 has Channel 31

Channel = Grade Checker  Assign a Channel to each Grade Checker  Grade Checker 1 has Channel 1

Different Radio Channels  Now the 2 “Rovers on site, the Paver and the Grade Checker have DIFFERENT Radio Channels

SCS – UTS Handover Procedure  Assign a Network ID to each UTS  UTS 1 has Network ID 1  UTS 2 has Network ID 2  Etc,

Paver – UTS Handover Procedure  Now when paving:  Leave the Channel set to your Machine’s Channel  Change ONLY the Network ID to select the UTS you want to use

Minimise Machine List  Only have the required machine in the SCS900 list  The UTS cycles through every machine in the list looking for a connection  A short list means fast connections 

Graphical UTS Handover  The next slide shows the method of transitioning down a road with multiple UTS –It is best viewed as a “Slide Show” so that you can see the site build and transition as the paver progresses down the road

Graphical UTS Handover Channel 1 Network ID 3 Channel 31 Network ID 4 Channel 31 Network ID 2 Channel 1 Network ID 1 Channel 1 Network ID 1 Channel 1 Network ID 3 Channel 31 Network ID 4 Channel 31 Network ID 2

Tip  Unlike these slides –  Do NOT use the default values –Change the Grade Checker Channel to other than 1 –Change the Machine Channel to other than 31 –Change the UTS Network ID to other than 1

Paver – UTS Handover Procedure While Paving

UTS Handover Procedure 1.Set 2D System to Manual 2.Stop 3.Grade Check 4.Write Down the PCS900 Elevation 5.In UTS screen Change Network ID ONLY 6.In UTS screen Start the UTS 7.CHECK the PCS900 Elevation

UTS Height Bust?  IF  < 5 mm (~2/10 th inch) –carry on  5 – 15 mm –Split the difference and bench  >15 mm (5/10 th inch) –Yell at surveyor  Find and use your own numbers

Can You Handover On The Fly?  Maybe  If your not paying for mistakes  If you have a really fast car to leave in  If nobody has your cell phone number...

Can You Handover On The Fly?  Maybe  If the design is smooth –No transitions ahead  If you have successfully Handed Over before and are using the same procedure  Have a fall-back plan –If not 3D after 10(?) m then stop and fix

Maybe??  Use next UTS as temp grade checker to check set-up
