Hardware status out of range

[John Thompson]

My T-LS said beep-beep-beep so I pressed the Warnings button. It said Hardware status out of range. I pressed the little arrow and it gave me this screen. Looks bad to me. Rebooting made the error go away, at least for now. Is this something I need to worry about? Is it going to need a trip to San Jose?

I also sent Log to Support. SN229.

Hi John, that is not good. It reports that you lost loop lock which leads to tracking issues in certain systems.
Do you experience outage of tracking for any system?
Regards,

I've used it for three full days since then and had no problems.

 

[Eugene Aksyonov]

Is this error still present or disappeared by itself?

 

[John Thompson]

It disappeared when I rebooted the Triumph-LS.

I have seen this same error half a dozen times since I first posted. Today was the first day that it persisted after rebooting. I rebooted a few times and it stayed there, but it's gone now. It appeared to still work. I had RTK fixed in the open areas and good checks to known positions. Air temperature was near 100°F and the LS was hot as a pistol. I needed to collect and stake some points that were in canopy and it seemed to have more trouble than usual fixing in canopy, but that's kind of subjective. I was at many of these same locations on a hot day about a week ago and it seemed to do better then, but maybe not.
Do I need to send it back? How long does it take to fix? Can I get a loaner in the meantime?

 

[Eugene Aksyonov]

I would rather replace the unit due this instability. Please read Andrew Simonov feedback soon on your RMA related questions.

Dear John,

I sent my LS to San Jose with an RMA. Haven't heard back yet about it. Working with a loaner unit (SN 319). Today the loaner unit said Hardware status out of range and gave me this screen.

I must be hard on LO locking loops...

John (or anyone else out there who might know),
What was the final result of your hardware status problem? I seem to be having the same issue. There is an alarm sounding and a red Hardware status out of range warning. When I click on that, I get the attached screen. It has been doing this for quite some time but does not seem to affect the operation of the rover.

I really don't know much more. I sent the T-LS to San Jose with that error and it came back without it. I upgraded to the T-LS+ a few months later and the T-LS has seen very little use since.

The TLS has three independent oscillators that are used in the RF front-end GNSS signal tracking. Each are monitored by a PLL status.
It appears that the LK-L03 is out of spec and the TLS unit needs to be inspected at Javad to rectify the issue.
