The instructions for changing the lamp can be found in the user's
manual. I believe in the most
current revision of the
manual for a MAC600, the instructions are detailed out on
page 5, and instructions for optimizing the lamp can be found on
page 17.
To summarize:
1) Remove any and all
power from the
fixture. If it isn't already, wait until the
fixture is cooled down. If your lamp hasn't worked, then I imagine you can skip this step
2) Remove the two knobby-looking thumbscrews that protrude from the back of the
fixture (opposite the fresnel-lens).
3) Firmly grasp the round disk (lamp burner assembly) and pull straight out, until the inside tip of the lamp clears the
reflector. You're going to have to contend with the lamp-leads on the outside of the
fixture...they actually have a little
bit of give and should allow you to remove that disk. It's a fine art of pulling firmly, but not too much.
4) Grasp the
porcelain base of the old lamp and firmly pull it out and away from its burner assembly (
socket)
5) Install the new lamp by reversing and repeating the above instructions keeping in mind that you do not want to touch the glass
envelope with your fingers, or any other material that could leave residue on the glass. I'd also suggest wiping down the lamp with an alcohol swab...some (most?) lamp manufacturers provide an alcohol wipe with the new lamp
6) Please use any and all
PPE necessary to safely perform this task
Do you know what kind of
ballast you have? (Magnetic or Electronic?)
I'm curious as to the color of your existing lamp...
Is it clouded and white? Does it have a dark
bubble on the side of it (or multiple bubbles)
Is it green or silver and perhaps shiny?
How long have you had the
fixture?
Has it worked as expected before the failure?
Was the failure immediate, or did it get worse with time?
Is the failure intermittent, or can you reproduce it 100% of the time
Have you tried to
power the
fixture on and off in between attempts to
strike the lamp?
Have you tried to
strike the lamp at the
fixture itself (as opposed to from your control
console)? (In MAN mode I think is the easiest way to do this)
When you're having a lamp issue like this and the
PCB thinks the lamp is not struck, it needs to see a lamp off command before you can try another lamp on command.
Now...on to the actual error...
Lamp Errors across the
Martin fixture line can occur for several reasons...but, if memory serves with the 600
line, you likely have one of four problems:
1) bad lamp
2) insufficient mains
power to the lamp
This could be due to a bad
transformer/
power supply tap, or a
circuit problem somewhere other than the
fixture itself.
3) a bad
ballast (either magnetic or electronic)
4) a bad lamp ignitor
5) could also be a bad lamp
strike relay on the
PCB, but I don't think you get the lamp error with this one...
Good luck! Let us know how things progress, so the next unlucky soul who has this problem can find his answers on this thread...
