Design Spot 250 09Er Error Code: Prism-Wheel Error

hi Brian, its a process of elimination. check the harness first going from the sensors to the pcb. make sure the magnet is still present. if you have another unit you may want to consider swapping sensors as well.

Best regards,

Thanks Gines...I'll try that first and let you know.

thank you too. we appreciate the business.

Gines,
I tried everything you said. The magnet was still present (looked just like the one on the good light), but I decided to try swapping them anyway. After the swap, both fixtures behaved exactly like they did before. So, I know the magnetic sensor is good.

The harness going from the sensor to the PCB is basically impossible to really trace back to the PCB b/c all the yellow, brown and orange wires are tie-wrapped with many other sensor wires (of the same color) going back to the PCB. So, instead, I just verified that all of the plugs on the PCB were secure and that there were no plugs hanging loose anywhere else.

What I did notice thought was that if I manually move the prism-wheel a little bit, the prism-wheel motor "hunts" for a few seconds and eventually lines up the magnet in the prism-wheel to the magnet in the sensor. I realize this is not a fix b/c this requires that the light lens be removed from the fixture...not exactly convenient before every show. But what it seems to indicate to me is that it's a problem with either the prism-wheel motor or some other component upstream of the the prism-wheel motor (perhaps the "driver circuit on the main PCB").

Knowing all that, what are your thoughts on what my next step should be?

Thanks,
Brian

Any ideas? I've got 2 Design Spots completely open on a work bench (for 3 days now). I would like to get to the bottom of this.

Thanks,
Brian

Gines,
After we talked on the phone, I checked the connectivity between the prism magnetic sensor and the connector on the PCB. All 3 wires checked out good.

Also, I tried swapping the PCB with the good light, and it still gave me the 09Er code. So, I'm inclined to think that it's not the PCB. Or, do you think it could still be the PCB somehow?

I felt the resistance of the good stepping motor vs. the bad stepping motor, like you suggested, and they felt about the same.

So, I've eliminated the magnetic sensor. I've eliminated the wiring from the magnetic sensor to the PCB. I think I've eliminated the PCB (but maybe not). I'm not sure if I've eliminated the stepping motor. Not sure what else to try.

I will call on Wednesday to discuss.

Thanks,
Brian

Hi Guys,

I have the same issue as Matchless1. I sent it in for warranty repairs but Elation sent the device back with the same problem. I opened up the device casing and can see the prism holder. Is there something I can do to fix this issue?

Thank you for your reply.

hi DJ. can you email me your information and the RA that you sent it in under. i will look into it asap. service@elationlighting.com

Hi, I sent in an email to service@elationlighting.com with the information that you requested. Please let me know if you did not receive it.

Thanks!

i did. just waiting to get with the tech to
see what options we have.
