five_pin_xlr Posted September 20, 2006 Share Posted September 20, 2006 Hi I own 2 Roboscan 812's and Have recently realised that when I power it up it does its checks then nothing happens. I assumed it was the bulb so changed that, and when I turn it on it ignites then goes out. The Pan/Tilt does not respond either to music (clapping), although I have the jumpers over DMX control, as I want to control it from my Spark. But is there a reason to why its going on then off and pan/tilt not responding to sound, becuase my other roboscan is fine?? The ballast perhaps, I dont know, if anyone does that would be great. Many Thanks Alex Link to comment Share on other sites More sharing options...
Ben Lawrance Posted September 20, 2006 Share Posted September 20, 2006 Have you set the dip switches to sound activation mode? If not then the unit will wait untill it is told to do something by a DMX signal. If I remember correctly, the dip switches for sound mode are 1,2,10. But this is printed on top of the unit. If nothing else, will be in the manual. Link to comment Share on other sites More sharing options...
johnhuson Posted September 20, 2006 Share Posted September 20, 2006 If you have the unit set for DMX control then the unit will not respond to sound, it needs to be in one of the auto trig modes to be able to do this. It is however possible to set it to Music Trig via DMX by setting channel 1 to a value between 139-170 (DMX) or 55-67 (%). With regard to the lamp, if the unit is set for DMX control then the lamp will not strike until a lamp on command has been sent. This is done by setting Channel 1 of the fixture to a value somewhere between 236-255 (DMX) or 93-100 (%). However the fact that the lamp strikes and then douses when fired up seems a bit strange.

3guk Posted September 20, 2006 Share Posted September 20, 2006 Might be worth opening it up and checking that everything is securely connected inside. That said if you are connecting them via DMX then you need to send them a strike command, channel 1 around 90-100% IIRC. Link to comment Share on other sites More sharing options...
Calder Posted September 20, 2006 Share Posted September 20, 2006 Are you remembering to reverse polarity of the DMX? C. Link to comment Share on other sites More sharing options...
five_pin_xlr Posted September 21, 2006 Author Share Posted September 21, 2006 well I have a 5pin 2 3pin DMX which I need to change poles 2 and 3 around. but year apart from that, it seems fine, after what you have been saying it should do.

zonino Posted September 21, 2006 Share Posted September 21, 2006 if its lamping on then turning off it may be overheating, have you checked the fans are working etc? Link to comment Share on other sites More sharing options...

fbnts Posted October 15, 2006 Share Posted October 15, 2006 When you say its lighting and then going out, do you mean that when power is applied it strikes for a split second and start its motor tests? If so this is normal. It should then reset all motors to start and then the mirror should move back to the dead center. If this is where its getting to then its waiting for the DMX signal. Check that you have jumper 10 set and then your DMX address correct. How old is the unit? I have had quite a few problems with our old roboscans - They too strike for a split second, do their self tests and then mirror moves to center and then nothing. Turned out that the Jumpers were at fault. I find that heat, smoke fluid and dust eventually kill the contacts and I have to desolder and solder permanent links in.
