RRC3 puzzle

Postby camacd » Fri Feb 26, 2016 1:41 pm

I have set up my RRC3, and it seemed to work fine initially, but now it does not do what it it supposed to when I power it up.

At power on it gives 3 short beeps, and the light comes on continuously, then nothing, just the light remaining on.

I have tried resetting the program, but no change.

The battery tests at 9.3v so there should be no problems there.

I cant find anything in the manual.

Can anyone advise?

Thanks
Cam

That sounds really odd. The altimeter startup sequence should be:

1. 5 second long beep (init mode)
2. 10 second baro history init time (silence)
3. Settings beep (when enabled) or POST fault code beep (if a fault, see POST fault codes)
4. 10 second launch commit test time (silence)
5. Launch Detect mode (continuity beeps)
a. A long beep indicates no continuity on any event terminal.
b. One short beep indicates continuity on only the drogue terminal.
c. Two short beeps indicate continuity on only the main terminal.
d. Three short beeps indicate continuity on the main and drogue terminals.

Are you getting the long beep? Three Short Beeps can mean continuity on main and drogue. The POST fault code should have 7 short beeps and then the code.

There are some members on the forum that have extensive experience with the RRC3, including beta testing, so hopefully you'll get an answer soon.

No, there is no long beep. When it first tested it, the sequence was perfect.

However, now, as I described in the first post, just three short beeps and nothing.

It may have taken a knock or two, while I've been building the rocket and fitting things up, and also I've done a few ejection tests, but i would have thought none of these should be too rough for this unit.

Still puzzled.

Also worth noting is that I get the 3 short beeps whether there is continuity on the drogue & main outputs or not.

Yeah that is 7 quick low beeps indicating a POST fault code. The 1 beep indicates a user invoked settings felt to factory settings warning. I have idea how to fix it.

Cam, did you get MW Jim's latest reply?

Your video depicts an RRC3 going thru a “settings default” as if you had powered up the unit with the PROGRAM button held down.  You’re hearing POST code 1, which indicates a reset to defaults.  There’s something wrong at mCU level, or there’s something causing superficial “shorts” to place the mCU in this condition.  Inspect the button and pads, and ensure nothing is getting inadvertently shorted out.

I suspect you are going to need to talk to the vendor or possibly Blake (assuming you got it from Aus Rocketry)
