Re: 1200GTO, Amber power LED and Inactive Hand Controller

I recently built a permanent pier site and placed the 1200GTO mount on the pier. I have finally gotten to using it and found that I'm having problems. I should note that I haven't used the mount for about 8 months.



The first problem is an amber power LED. I've read through previous messages on this forum and the troubleshooting section of the manuals for both the mount and the hand controller (GTOCP3). I can't really tell if my problem is unique or one of the ones already described in my prior reading.



I'm using the power supply I purchased from AP when I ordered my mount. It is a 15v power supply. I've tested it and it still produces 15.11v at the output terminals and with the adapter to the power cable.



I did have some problem having the LED stay lit but resolved that by following the suggestions to nudge the post in the power socket for better contact.



The current state is that with power applied from the PS, I have an amber LED and a keypad that shows nothing. The only response I get from the keypad is a beep when I press any of the direction keys. No other key causes a beep. Nothing is visible on the display panel.



What should my next steps be?



Should I assume the servos are in "safe mode" or "motor stall"? I'm not sure how they would have gotten into this state. One thing I haven't tried is a different set of mount cables - which I don't have.



Does anyone have an idea why the keypad acts as it does? This seems different than anything I've read about other keypad problems.



There is a telescope on the mount (Celestron Edge 11) but I balanced it prior to applying power to the mount.



I apologize if I haven't provided enough information. I'm not sure how much is too much or too little. If anyone has suggestions for further troubleshooting steps, I'd be happy to try them out.



Regards,



Jim Fleming

You may have several problems. The keypad is not necessary for the mount to operate at sidereal rate. The fact that the light is amber has nothing to do with the keypad - that is a seperate issue.



It woudl be best if you called tomorrow and talked with George. He can run you thru some tests that will allow him to determine where the fault lies.

Roland,



Thank you for the quick response. I will follow up with George this week.



I knew it was likely the two problems were unrelated but wasn't sure how much information to provide.
