LEICA 1105 - no tracking past 185 feet

I am using a Leica 1105 robot with an Allegro MX using SurvCE Version 2.62.
The issue am I having is that it will not fix a backsight or read a distance past 185 feet.
It works fine up to there.
The instrument has been checked out by the local shop( although it has become apparent that they did not use my datacollector or radio) and "worked fine up to 1500feet" . I do believe that but cannot make it happen for me.
I fully charged all batteries and used two different Allegro data collectors both with their own respective radios and still the problem persists.
My brick battery is old so that is suspect but it does read "high" for sometime on the instrument before falling to medium.
The problem is the same whether the DC remains at the gun or at the pole.

Any help or ideas are appreciated.
I will not be able to get back to this post until about this time tomorrow night but I will be back.
Thanks in advance
Mark Myers

Sounds like the ATR camera is going out, see if you can recreate the problem without a DC.

When I have seen em go out on the 1200 series you can still get a EDM return without ATR but as soon as you try to shoot with ATR or tracking the range drops to around 150-200 ft.

Play around with it. Is the EDM properly aligned? That'd be the first thing I'd check. If you have a mode, to get the strongest return signal, set it up at 150', and maximize the signal, then try it at 250. I think that is a narrow beam inst. IF the signal is not aligned with the cross hairs, well, that is typical. Some shops don't know to check this. Some instruments are built with a FAT wide beam. With no adjustment.
Hope this helps.

I agree this sounds like an ATR issue. When the camera goes bad you will notice while you are locked on a prism instead of seeing the steady circle with the cross you will see it switching to the binoculars and then back. Never totally locked. Trying to do an ATR calibration often fails. Of course the EDM may also be part of the problem.

Those TPS1100's are getting awfully hard hard to find parts for. Let me know if you end up needing to upgrade to something newer. I'm looking to sell my personal TCRP1203.

ATR is okay guys the local shop got it to work out to 1500 feet. If we are gonna start the part changing process lets start with the cheapest part.

If it's not "fixing" on the backsite there's an ATR problem. Is the local shop a factory authorized Leica Service Center?

Just do the simple test ....shake well the gun rotate spin fast the telescope few times both sides then try it. If the problem appears straight away or later that mean your gun is not fixed. By opening touching some internal parts then assembling ..one part came back in to the right position but should be replace ask your service shop what was done.
ATR has nothing to do with EDM or vice versa if there is problem with any of them. EDM range drops ...check first if is properly aligned if yes then motors on EDM boards straggling soon one of them will die especially for return signal. Solution ...new EDM board or repair the board for much less.
ATR problems....mostly on TPS1100/1200 series with Power Search one part is very weak doesn't last for long has to be replace.
Another common problem on TPS1200...jammed or not working electronic/digital circle level. More time to fix it half of the instrument has to be striped.

Does anyone know if I can run my robot leica 1105 with my trimble/recon running SurvCE 2.62?
Right now I m using it as a manual TS,typing by hand in my data collector.
Thanks

Sure you can. You just need a Wild style serial connection cable. It won't be a robot because the Recon has no radio, but at least you won't me manually entering anything.

I don't have enough experience with Leica to be familiar with its hiccups, but with my Topcon robot battery problems will cause it to lose lock. Even though the battery indicator says it's good, the battery may be weak, especially when I'm using the on-board batteries.
