Martin Posted November 9, 2010 Share Posted November 9, 2010 Does anyone have a list of error messages for the original rainbow pro scrollers. I have a scroller with an "E 20" error, but can't even get into the menus on the unit. The manual doesn't list the error messages. The manual for the Pro2's does but they must be different as it only goes up to E16. Link to comment Share on other sites More sharing options...
Charris Posted November 9, 2010 Share Posted November 9, 2010 Hope this helps:From Rainbow Tech manualERROR CODES PRO RANGEERROR CODES/MESSAGES – Some are shown together with a slow yellow LED flash.E-10 No communication between the H8 main processor and the PIC.

martinw Posted August 17, 2018 Share Posted August 17, 2018 Hello I have a broken 6" Pro (not Pro2) scroller, which currently has no scroll in. When I turn it on, the display shows "Load" and "-00-". If I press the Enter button it flashes between "bLOC" and "oooo" and turns the spindles in quick bursts a number of times. After about 20 seconds, it stops doing this and displays "jErr" and "bLOC" flashing on the display. If I press the arrow keys at this point it starts spinning in pulses again, sometimes in one direction, and sometimes in the other. Any idea what's wrong here? I'm guessing either the analog pot, or the optical sensor on the motor might not be working, but if anyone has serviced one of these an can give me pointers, that would be very helpful. I can do electronics repair to a fairly advanced level. I have a tech manual for the Pro2 - are there any docs or service manuals specifically for the Pro1? Thanks Martin Link to comment Share on other sites More sharing options...
alistermorton Posted August 17, 2018 Share Posted August 17, 2018 Not used that scroller myself but it sounds like it's trying to find the first frame which, without a scroll, it can't. Which reminds me, speaking of scrollers ... Link to comment Share on other sites More sharing options...
gareth Posted August 17, 2018 Share Posted August 17, 2018 Knackered encoder. Frequent problem with Rainbow Pro. We used to ship ours to White Light for repair when they started displaying these calibration errors - the theatre I worked at owned 18 of the first-generation Rainbow Pro 8", and I think pretty much all of them developed this fault at some point.

jonathanhill Posted August 19, 2018 Share Posted August 19, 2018 Put a scroll into the unit, then power it up. It will run through a (lengthy) calibration sequence. If it still shows ‘bLOC’ it will need to go to a service agent as it can’t find its home point. Link to comment Share on other sites More sharing options...
martinw Posted September 4, 2018 Share Posted September 4, 2018 As Gareth suggests, this turned out to be failure of the encoder (mounted on the motor). If anyone else has this issue, it's quite easy to fix if you can solder. The part is a Honeywell HOA0901-011, which is currently available from Digikey or Mouser, but is obsolete, so if you have some of these scrollers and want to keep them running for a few more years, then it might be worth buying a few spare encoders, just in case.

gareth Posted September 4, 2018 Share Posted September 4, 2018 If the part is now obsolete, then it's definitely worth stock-piling a few if you're a Rainbow Pro owner. It's not a question of 'if' the encoder will fail in each unit - it's a question of 'when'. Link to comment Share on other sites More sharing options...
