Amada LC2415 Shutter Enable
(OP)
Hi Folks,
My Amada LC2415 is giving an "2158 Shutter Enable" alarm.
Does anyone know what this is?

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.

Could mirrors cause this?
RE: Amada LC2415 Shutter Enable
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 Joe is your repair guy, tell him said hi next time you see him.

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?
RE: Amada LC2415 Shutter Enable
It can also cause problems you are describing. I've had it with our LC2415.
RE: Amada LC2415 Shutter Enable
This solved our problem
RE: Amada LC2415 Shutter Enable
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.

You learn some thing everyday.
Just thinking out loud, surely if it was a limit switch wire, an interlock error would be logged?
RE: Amada LC2415 Shutter Enable
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.
RE: Amada LC2415 Shutter Enable
There are four switches. If pressed, a "Z-+ interlock alarm apears.
If a program is run with the shutter key disabled, the machine will run to the end of the program.
RE: Amada LC2415 Shutter Enable
I'll let you know what transpires.

Yes and no ....
I had a local representative from Laser Experts take a look. Great people to deal with.
The oscillator was cleaned out and mirrors replaced. Two tubes had holes or cracks and we're replaced. The optical coupler was inspected and found to be not perfect, but ok.
A week later the machine was running perfectly.
Three days after that, the same error came back. I had a 5 ton paper weight again and mounting costs resulting from a complete lack of productivity.
The Laser Experts guy came out again and inpected the oscillator. It seemed fine.
There is a power sensor to the right of the optical coupler. He checked that as well as the connections to the board. It seemed to check out fine. Thesee items weren't replaced but when the machine was powered up again, it worked again. I have no idea what the problem was but suspect that it may be back again.
The 2158 error is very general and can indicate a number of problems. Pitty a trouble shooting type chart isn't freely available.

I do have them at the office. Please supply your email address and let me know what Amada have to say.

Would a chiller alarm not present itself though?

Im waiting for fanac to come out to do a mirror clean first and will then have amada come out . Will keep you informed of what they find . Thanks))
