scan fail safe board

[stanleydj]

hi all anybody recommended any money friendly safe board ? i love to have pangolins PASS but cost 2much

Mylaserpage.de
I have 5 of these currently.

TBH, compared to PASS, the mylaserpage board is rubbish, its way to slow.

Pretty impressed with the Kvant safety board, still a digital board, but fairly fast acting and very predictable.

And Dave's board will be available when?

Is the kvant board available as a part ? I'll be on the hunt for couple more scanfail's pretty quickly.

Edit : Just found it. Pricey.. Almost can get a pass for not a lot more.. I notice the specs for the kvant are 25-50ms, which isn't all that fast. In your experience you find them superior to Guido's board ? (If I remember correctly it clams around 25ms..)

I'm not that impressed with the Kvant board although its probably down to needing some adjustments.

In mine it intercepts some ordinary cues in output setting. Is QS / Beyond putting out unsafe cues? I very much doubt it. So I only use it in input setting which guards against input failure. Here is does impress and operates quickly and efficiently every time. I do actually have the pot data to adjust it but have never got around to trying it for fear of making it worse or removing its protection by slowing it too much. The issue with output setting is it interprets some slow moving beams in ordinary cues as sufficiently static as to pose a danger and cuts them or strobes them on and off as a result.

PASS is about as good as it gets although I believe it does need manual setup before every show (where the projector is moved to a new location) to guarantee safety as its based on setting safe MPE levels and zones. If you're leaving the projector in one place permanently, then you should be able to set it up the once.

Dave, given that the Kvant board and Guido's board are roughly the same speed (Guido claims <20ms, Kvant are 25-50ms), they are both significantly slower than PASS, what is it about the Kvant board you find better than Guido's, given that it costs nearly 3 times as much, and seems to react slower?

Does the Kvant board allow setting a horizon like Guido's for the purposes of hot beams?

Kvant would do well to publish a manual to their website really, as info is sparse. However, given that PASS is $500, I don't think there's any competition if I was spending over £200 on a safety board. It would be PASS all the way.

Is QS / Beyond putting out unsafe cues? I very much doubt it.

Why do you doubt it? QS/Beyond doesn't have any safety features built in afaik, so it is perfectly capable of projecting a cue that may violate a safety board setting.

The issue with output setting is it interprets some slow moving beams in ordinary cues as sufficiently static as to pose a danger and cuts them or strobes them on and off as a result.

So, you've defeated the safety system that detects unsafe beams/cues because you know better, right?

A good friend of mine also reports that the $500 price tag is a "base" price and does not include the optional optical feedback (ie: power meter)
So I'm not sure of the entire cost of the system, I'm sure it's worthwhile if you're audience scanning though, which is exactly what PASS is designed for, it's not just a "scan fail" device.

Because from memory Bill Benner told me he has checked all the supplied cues in QS for safety personally and as one of the world's leading laser safety experts, I take his word over some software settings. I had extensive discussion with him about the safety board and he assures me that the QS workspace contains no cues as supplied that are in anyway inherently unsafe if displayed in a conventional manner. This doesn't alleviate the need to take MPE readings if audience scanning of course.

So, you've defeated the safety system that detects unsafe beams/cues because you know better, right?

Not defeated anything Norty. You have a choice via a switch on the back of the Kvant of 2 safety methods input or output monitoring. I just chose to set mine to input monitoring as the output monitoring was causing problems.

Regarding the manual. There isn't one or at least there didn't used to be when mine was fitted. I was just given details of which pots to adjust. However, its not information I can pass on.

Color iris. From eye magic s pretty good I hear. I have one but never installed it.
