IREM AS16040 Igniter and Prevost P86X

[MarinBNM]

I'm using this igniter with 500W horizontal bulb, and I have problems for hard striking lamp. Rectifier has 120V open voltage, and when I connect it to 900W lamp house on other projector is working without problems, so rectifier is OK.

 

But on this Prevost with Irem igniter it strikes about when i try 10 times or more.....can be problems because this igniter is for bigger bulb (is mentioned up to 160A) or may bee because high voltage is coming to + (Anode) of bulb?? On this machine is mentioned to be a AS3040 small igniter, but I can't find original, but this aslo fits in it.

Hello Marin. I think, the ignition pulses are first too long an second too high voltage. I know this igniter. Take out the original 'electronic' and replace it by only a 48 to 60 volts relay an a zener diode of 47volst an a 1n4008 to prvent false polarity. fthe open voltage will turn on the relay for the short time the lamp needs for ignition.

if you have futher problem, reduce the ignition voltage by using a bauch spark gap. with this type you can regulate the ignition voltage.

Yes, this was problem, I figured out also because when I saw sparking garp in lamphouse where bulb working I did noticed small distance on gapper, so I did even replace gapper on Irem because original is noisy :lol: and is bit melted.

Hi all again!

 

Well...again problems with this crap.....I have rectifier which I did rewire as Stefan did pointed me.....and with mine 900W bulb at home it works perfectly, it ignite every time!!

 

And when I connect it to P86 which have 500W lamp and AS16040 igniter it don't work good...it you want to ignite lamp first we must put switch for higher current and when lamp strikes then put it to nominal waleu )but with 900W at home that isn't problem)...I did try to replace igniter capacitors, sparker, lamp.....but always the same.....another strange thing is that when you strike it the lamp momentaly lights (not light spark because of ignition, but real light) but only for a quart of second and then it gone off and you see voltage drop down what is normaly because lamp is starting and booster capacitor is descharging.

 

So if maybe someone have more idea about this problem...?
