Amada LC2415 Shutter Enable 1

It usually means that the high voltage had dropped out. This is most often caused by a E-stop. Best thing to do is turn the shutter key off and then see if there are any other alarms that present them selves. Remember, there are two alarm pages, "ALM" and "MSG". Assuming you have a 16L or 160i control.

Thanks for the replies guys.
I have checked both "ALM" and "MSG" and there is nothing to report. This is a 16L controller.
I called the tech guy who is away for two weeks. On the phone, we checked few parameters and the power seems to be there.
Could it really be as simple as the key switch?
The machine starts cutting, but stops a minute or two into the program.

Not likely. If was mirrors, you would get "laser power down" or "Laser not generate". Those alarms would require you to completely shut the machine down and restart the laser.
If you get this alarm, and you don't do anything else, like hit reset, and just turn the key off, that alarm goes away and no others are present, its probably an e-stop.
I am sure if you look at the H/V light under the Laser key switch its out. If you look at diagnostic 908 (i think) "laser sequence" = 20. That would mean you laser is in "stand-by". And more than likely a E-stop has caused it.
I think your pulsar is about 20 years old and one of the wires that goes to an emergency stop limit switch has broken, kind of. I say "kind of" because it only separates when the y is moving back and forth. The e-stop circuit has 24v on it all the time. When the limit switch is activated, the 24v doesn't' get back to the control and puts the machine in e-stop. Same thing happens if the wire is broken. A.K.A. "Fail safe"

Laserninja, SPOT ON!
That is the exact scenario.
When it does this, we have to power down the machine and power it up again. The time loss is hugely frustrating.
Thanks for your advice. I'll try to trace the wiring for the limit switches in the morning.
This has been a problem for about a year now. It used to happen once a month, then once a week. Now it's every ten minutes, rendering the machine unusable.

If you just flip the laser key off, then back to on, the laser should come back on in about three minutes.

Nope, not Joe I'm afraid.
Interestingly, just tried again. Part cuts, shutter enable alarm pops up and machine stops as above. There are two alarm messages. 4090 laser alarm: laser not generate, and 4076 laser alarm: laser power down.
Are these symptoms typical of an e-stop issue still?
Still tracing wires on the limmit switches. Nothing found to be faulty yet. Focusing on Z and Y for the time being.
Surely if it was a limit switch, the machine would log a message for it, or not?

What about faulty temp sensor in chiller?
It can also cause problems you are describing. I've had it with our LC2415.

I don't think its the laser gas. We've used two thirds of the cylinder and it was fine before.
The chiller is a possibility. It's winter here at the moment. The chiller is set to 21.6 degrees.
In the mornings, after the machine has been shut down for the night, the water temp drops to around 9 degrees.
Saying that, it was still throwing the alarm at me when the temp was at 25 degrees.
The key switch ...
After the machine goes into error state, I turned the laser key off momentarily, and turned it on agin to get the high voltage back on. It never came back on so I shut the machine down again and started again.
Still baffled, but still tracing wires to limit switches.

When you turn the key off do you wait for the third beep before you turn it on again? or do you turn it off and on again right away? If you get the high voltage back check the coefficient and see if it's over 1150 because an internal leak could be the cause.

I looked through the schematics I have for that type of machine. I can not find an emergency over travel for z. I may be wrong. On the control side of the cutting head, there are three or four roller limit switches. Would you try manually pushing the switches to see if it causes the same condition?
Also, you said the alarm comes up a lot. If you run a program with the shutter key off, does the machine stop mid way through the program? I am trying to figure out if the machine is stopping the laser or if the laser is stopping the machine.
