3D Paving Training Start Procedure &

UTS Handover Procedure

Phil Jackson Training ManagerMarch 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 – UTSHandover 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

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 – UTSHandover Procedure

While Paving

UTS Handover Procedure

1. Set 2D System to Manual2. Stop3. Grade Check4. Write Down the PCS900 Elevation5. In UTS screen Change Network ID ONLY6. In UTS screen Start the UTS7. CHECK the PCS900 Elevation

UTS Height Bust?

IF < 5 mm (~2/10th inch)

– carry on 5 – 15 mm

– Split the difference and bench >15 mm (5/10th 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
