NEC GLS3053 Argon PSU interlock I/O pinout info

[timelablasers]

Hi all,
I have a NEC GLS3053 Argon laser power supply and need pinout information for the interlock/remote connector marked I/O. If anyone can provide me with this info, I would be very grateful.
Thanks!
Rob.

I tried a google on this psu but found nothing, strangely enough.

http://www.repairfaq.org/sam/laserasc.htm#ascsp1br <-- the pinout for the SP261B connector could be the same on your NEC psu, could be worth a try atleast.

Hey thanks for that. Might be worth a shot. It's probably the closest thing I've seen so far. Thanks for finding it for me. :thanks:

No problem. I´ve been lurking around sam´s laser faq on and off for pretty much the last 10 years.

Hello,
i just purchased some sort of medical laser that has this NEC head and psu,
i cannot adjust power on mine but at least it fires,
jump 4 and 5CORRECTION 4 AND 5 ARE NOT LINKED 4 IS SHIELDING FOR 5, 10 and 11, 36 and 37, mine has floating wires (previously hooked to other boards) 5, 26,27, 34,35, if someone knows how to increase power please let us know.

Thanks

Sam'sFAQs will definitely have the answer somewhere. I find it really hard going but usually find it eventually.

I discovered that turning a variable resistor inside the power supply allowed me to adjust output power as long as a couple of the pins in the I/O connector are shorted.

Ehm ..... variable resistors INSIDE the PSU are usually used for set the maximum levels when the remote is connected and the power regulation on the remote is turned at maximum, and the idle level .....

Is NEVER a good idea, to touch them, if not for recalibrate the PSU after a repair .....

It's not a problem if you know which variable resistor to turn. I've used it this way for ages and nothing has happened to prove this method wrong. It's also an old simple supply so much easier to figure out its workings.

And the correct pot is ???/??

I'll have to open up the PSU when I have a moment and take a look....will add that info on here once I've done that.....

great!!!
