Denise Brunner Posted August 20, 2011 Share Posted August 20, 2011 Using the servodog to program an 8 channel animated "Mr Winter". Suddenly all went dead. Led on board on longer lights or flashes, hardware utility can not find the device and I checked the power supply, unattached I have 12V DC, attached 1.2V DC. Figured I might have a false 12V without load, so I put a 12V bulb on the power supply and it lights. Don't have a spare power supply to test just in case, but I think it is the board!!! Very Frustrated right now. Link to comment Share on other sites More sharing options...
Denise Brunner Posted August 20, 2011 Author Share Posted August 20, 2011 an update. Unpluged the two jumpers that supply power to the servo buses and when only one was hooked in, the other bank began to work. So I pulled out all servos in that bank and reput the jumper in and tested. On the second bank, all servos operate but one (channel 6) Then I plugged in all the other servos in the first bank and they now all work. Plugged the orginal channel 6 into channel 7 and it works fine. So now I have the board working again and just channel 6 is out. Any ideas????

Dan C Posted August 20, 2011 Share Posted August 20, 2011 Can you try a reset on the board? Link to comment Share on other sites More sharing options...
Denise Brunner Posted August 20, 2011 Author Share Posted August 20, 2011 Reset the board via the jumper, same result. Channel 6 dead. Link to comment Share on other sites More sharing options...
-klb- Posted August 20, 2011 Share Posted August 20, 2011 Try reprogramming the servo limits on that channel. Link to comment Share on other sites More sharing options...
Denise Brunner Posted August 21, 2011 Author Share Posted August 21, 2011 Tried reprogramming the limits, utility says it succeeded but still no change in operation. Link to comment Share on other sites More sharing options...
Bernie Posted August 21, 2011 Share Posted August 21, 2011 Did you try a new or different servo on channel six?? Link to comment Share on other sites More sharing options...
Denise Brunner Posted August 21, 2011 Author Share Posted August 21, 2011 yes I did, moved another servo to channel 6 and it did not work, moved the servo that was on channel 6 to channel seven and it works fine. Channel 6 just appears not to work. Link to comment Share on other sites More sharing options...
Dan C Posted August 21, 2011 Share Posted August 21, 2011 Sounds like something went bad. Possibly a solder connection? IDK. You could try and give LOR a call and see if they can just swap it out for you. Worth a shot. Link to comment Share on other sites More sharing options...
Bernie Posted August 21, 2011 Share Posted August 21, 2011 Denise, If you have multimeter you can try carefully measuring the voltage on the pins for channel 6. red/black . The white wire is the signal.Note for reference: Most servo mfg's do not recommend voltages above 5.25 vdc for analog servos and 6.15 vdc for digital servos. The higher voltages can cause the servo(s) to overheat and fail especially when under a load (stalled).Bernie Link to comment Share on other sites More sharing options...
Denise Brunner Posted August 22, 2011 Author Share Posted August 22, 2011 Thanks Bernie, I will try and measure the voltage, but its a brand new board (1 month) and I left the voltage regs set where they had them - which I was told was 6 V. Anyway, I put a service ticket in over the weekend.Thanks everyone for all the help !!Denise Link to comment Share on other sites More sharing options...
Marty Spain Posted September 20, 2011 Share Posted September 20, 2011 Hi Denise,I just bought a ServoDog controller, I would be interested to find out what LOR has to say about your cnannel 6 failure. I am just getting started on using servos into my light displays so I am looking for info where I can find it along the way.Marty168 channels, 15,000 lightswww.pbase.com/hejhog You can see my light here!

Denise Brunner Posted September 20, 2011 Author Share Posted September 20, 2011 LOR has been great, they sent me a new buffer chip, which did not correct the problem. They then sent me an entire new board at no charge. This board has been working fine.Denise Link to comment Share on other sites More sharing options...
