Sigma 3 reel questions: Manuals, door buttons, keys.

[PyroJim]

I just got my first Sigma machine.  It's a 3-wheel model number I-3213.   I believe that it came out of Boomtown Casino in Nevada.
I've looked in the NLG Files section and I do not see a manual for it, but the manual for the SG-32 and the SG-50 are very similar.  Is there a seperate manual available for this particular model?

I've got it working pretty well so far, but I have not figured out how to run it with the door open.  Pushing in the little door button switch does not seem to fool it, there appears to be something else.  Can anyone tell me what the secret is to running it with the door open?

I have the main key to the cabinet and the key to the CPU door, but I do not have the key(s) to te the reset switch or the other two rotary switches on the side.  Are these available anywhere?

Thanks all.

First
 

Next, the "wheels" are more commonly known as "reels"  - like you'd see on a movie projector. (Remember those?  )
Is there any particular problem where you need to see it running with the door open?
I'm definitely not a Sigma expert but very likely there's optic circuits that are "cut" when the door is open. Obviously these are needed for when the machines were in casinos. They can be bypassed easily though if you really don't want them in use. Post a photo of your machine and one of the side where the other switches are. In some cases, it's just easier to replace those with push button stitches or toggle switches. Or, just find a replacement key switch.
I'll PM a more experienced member and he should chime in with more (and perhaps better) information.

Welcome!
I seem to recall asking the same question on my Sigma. As Mark said, I think it is an optics sensor, it shut those reels off when the door is open.
Regarding those 3 key switches: The owner before me made the decision for me because they drilled them out thinking they were door locks. As such I had to replace all 3 no questions asked. I installed push buttons so the future generations wouldn't need to have 3 keys to deal with. Since one was accounting it is means you would surely have at least two keys because floor personnel do not have access to accounting info. If I recall the three switches are: Accounting, Previous hand, payout reset.

If you really want to use key switches you would pull them and have a locksmith re-key, or buy new key switches. If you did the later you could use the same key for all.

Keep us posted and send pictures of your machine. Those Sigma's are really fun to play.
