Need help with Amergraph ULF 28
I have an Amergraph ULF 28 contact printer which, up until Thursday (2/26) worked fine. Then the following happened..

I exposed one kallitype print , then when exposing a second print, when the UV bulb came on, it flickered for a second (or less), went out, and tripped the breaker switch that is connected to the dedicated line that I have the ULF 28 plugged into.

I repeated the process again & the same thing happened. In fact, I repeated it a number of times with the same result. This had happened episodically before, but once I reset the breaker switch, the bulb came on without incident & completed the exposure. This is the first time I had this happen repeatedly. I purchased the printer in late 2012 & started using it in early 2013. The unit still has the original bulb.

Is this a sign that the bulb is going out, or is there something else wrong. I thought that since the bulb at least comes on momentarily, that there might be a fuse issue.

Anybody out there have any ideas?? I contacted Amergraph for tech support on Thursday, but haven't heard back from them.

Any help would be appreciated.


Thanks for any info you can provide

Just spotted this...

Did you resolve the problem?

Are you on a 15-amp or 20-amp circuit?

Is it a dedicated circuit?


A few answers to this may help you come to a resolution on the problems.

Getting a new bulb seemed to cure most of the problem.

My ULF-28 is on a dedicated line w/ a 15 amp breaker.

I should still probably go up to a 20 amp fuse, because I will still trip the breaker switch occasionally, but not as often as when I wrote my original post.

I haven't replaced the breaker, because I will hire an electrician to do this & after replacing the bulb, figured I could live w/ it for a while.

Thanks

Tom,

OK, good to hear...

Did you check the voltage of the line as the recommend in the manual? If you are getting a voltage dip, you probably need to increase the line to a 20-amp.

That will require pulling new conductors (15-amp is #14, and 20-amp is #12), and then also putting in a new breaker. It's easy to do all of this if you have good access to where the lines are run. A bit harder if they are in concrete or other walls, etc.

Yes, that is what I need to do next, but have been avoiding it because line is in a wall.
