Trimble SPS 730 and SPS 930 Universal Total

Trimble SPS 730 and SPS 930 Universal Total Stations How to Setup for Machine Control

Agenda • Using Trimble SCS 900 Site Controller Software to setup for Machine Control – Setup the SPS 730 or SPS 930 Total Station • – – Establish and orient the instrument Set the search window Set the Trimble MT 900 target ID Edit the machine list Hand off to Trimble GCS 900

Setting up the Total Station • Use a heavy duty tripod – Trimble recommends p/n 571126275 – Needed to stabilize high speed Trimble Mag. Drive™ servo mechanism – Plant legs firmly in the ground, using a wide stance – Mount and level instrument

Setting up the Total Station • Using either a Trimble TCU or TSC 2, start SCS 900 – – • TCU or TSC 2 will auto connect when attached or cabled TCU or TSC 2 will not auto connect over Bluetooth or radio From the Main Menu, tap System Setup (6)

Setting up the Total Station • Next, tap Connect Instrument (1)

Setting up the Total Station • Next, tap the method by which you want to connect. • Connect via Radio is used here (1)

Setting up the Total Station • Next, set the radio channel and ID of the controller – This is the channel and ID stored in the instrument for later SPS use – Radio channel 1 -30 are used for SPS, 31 -60 for MC – Network ID is a value from 0 -255

Setting up the Total Station • Once you set the correct channel and ID, tap Next and the controller will connect to the instrument

Setting up the Total Station • • At the next screen, tap OK once you are satisfied with the leveling of the instrument Make your selections on the next screen and adjust temperature if necessary, tap OK – PPM is automatically computed based on the values input for Pressure and Temperature

Setting up the Total Station • When returned to the System Setup menu, select Setup Total Station Position (2)

Setting up the Total Station • Tap (2) to setup over a known point • Tap (1) for a free station setup CP 1 – You must be able to see 2 or more known points for this setup BAD SETUP! GOOD SETUP! CP 2 CP 1 CP 2 Resection angle degrees Resection angle 30 <30 – 150 degrees

Good vs Bad Setup • First setup, instrument and control points are in a line – Bad geometry for a re-section – No intersection angle could result in poor computed position of the instrument • Second setup, instrument and control points form a decent triangle – Good intersection will result in a good computed position of the instrument • Avoid free station setups where intersection angles are very narrow (<30 degrees) or very wide (>150 degrees)

Setting up the Total Station • Follow prompts in measuring to control points to position and orient instrument • Setting up over a known point requires measuring to at least one other known point • Setting up over an arbitrary location requires measuring to at least two other known points – The more points measured, the better

Setting up the Total Station • Once you’ve measured to either one (known point setup) or two (arbitrary location setup) control points, you are brought to this screen • Choose Complete Instrument Setup (2)

Setting up the Total Station • You are now given two options – We will choose Setup for use with machine control (2)

Set the Search Window • • Define your search window Tap the Set button after aiming to each location – – • Either top left/bottom right, or top right/bottom left You will see green circles once the corners of the search window have been recorded Tap Next once both corners have been set

Search • Two searches instrument performs – Quick search • Small search window based on last tracked position of target and a horizontal / vertical window defined by angle values in SCS 900 – Full search (search window defined in SCS 900) • • Should be looked at as the extents of your working area If quick search does not reacquire lock, instrument goes into full search

Set the MT 900 target ID • The next screen allows you to set the target ID of the Trimble MT 900 Machine Target – – – If aimed in the vicinity of the target, tap the Check ID button, and SCS 900 will retrieve the target ID the MT 900 is currently set to If you know which ID the MT 900 is set to, select it from the drop down and tap Next If you wish to change the target ID, select the number from the drop down, and tap Set Target ID

Changing the MT 900 Target ID • • • Only necessary for SPS use with the MT 900 If you wish to change/set the target ID of the MT 900, you must be connected to the MT 900 via the MT 900 Junction Box Can also be changed later via the Trimble CB 430 Control Box and GCS 900 IDs 9 -16 are used strictly by the MT 900 IDs 1 -8 can be used by either the MT 900 or the active target ID box for SPS use – 1 -8 should be used for MC only as last resort

Edit the Machine List • • • Once you finish setting the MT 900, you are brought to this screen If the machine list was previously loaded to the instrument, tap Get Machine List and it will be retrieved by SCS 900 and will populate this screen If you are creating a new list, tap Add…

Create an Entry in the Machine List • Radio channels 31 -60 are reserved for MC use, 1 -30 for SPS use • Give the machine a specific name and assign a radio channel from the drop down list, and tap OK • Load up to 5 separate machine names / radio channels

Edit the Machine List • Once you’ve loaded all the machines that you need, tap Save • Giving the machine a unique name that the operator can remember will help in cases where multiple machines are used on site • Name the instrument (not shown), tap Next

Hand off to GCS 900 • Point the instrument in the area work will start and tap OK • The instrument radio is configured for MC use Now disconnect from the instrument at the next screen • – If connected via radio or Bluetooth, the connection will be terminated for you

Hand off to GCS 900 • The Face 2 display on the instrument shows the instrument scanning one SPS channel, and then the machine control channels loaded earlier from the machine list • Station setup information is written to a memory location in the instrument – GCS 900 then calls that information from the instrument

Summary • Setting up with SCS 900 takes the normal time to setup and orient an instrument, plus a very short amount of time to go through the Machine Control wizard • MT 900 – Target ID 9 -16 reserved for MC only, 1 -16 available (use 1 -8 as last resort only as these are the only IDs available for SPS use) • Radio – Machine use, channels 31 -60 – SPS use, channels 1 -30
