Resolved. I found the right connections to jump, but I can’t remember what they are.

Just circling back to close out this thread. The belt I bought above was a perfect fit. Installation was fairly easy. Took about 3 hours. We could do it quicker second time around. Removed the...

You're probably right - I just ordered the same belt that was on it and it's not original. It's 20mm wide and the pulley is 1.5". So I bought the 30mm version of the same belt. However, the...

I just bought 6486K216 MMC. My belt was indeed broken. Hopefully that's the only problem. Will find out tomorrow night or Friday.

Thanks for the idea Rodney. Doesn’t look like that was it. I’ve pushed it with great force and it goes all the way down without resistance. I don’t think it was tripped.

Also, playing around...

Hello,

I have a 1997 Fadal VMC15. Today I made a dumb mistake working too fast and not paying attention. Put the wrong size blank in and stalled my spindle on a facemill. I reset everything,...

I jumped them, but no change. Found the wiring diagram for the bar feeder. It has an E Stop circuit on both the Input and Output cables. Both connect to a relay in the Puma. 2 wires ea.

Hi all,
I'm getting rid of my bar feeder to make room for a new mill. After disconnecting the bar feeder, the lathe throws a OP Emergency PB/LS Off alarm along with some other messages. I think...

That's what I was afraid of. Thank you for the confirmation.

I did get the machine running today, but no idea how. I just kept trying to turn it on occasionally. Once on, it runs great. I left it on tonight in hopes I don't have this problem tomorrow, but...

Darn, thanks for trying.

Just bought a 1997 Daewoo Puma 8S. Have run 2 jobs on it so far. Just booted it up Monday morning and have the error in the title. I've identified that the middle amp in the top of the cabinet...

Realize I'm reviving a dead post but I'm not finding anything more recent and this one's right on part.

I just acquired a 1997 Daewoo Puma 8S and am trying to figure out the tool setter. ...

In case anyone finds this, I believe we found that the relay is bad. Loud noise we heard at different times was the motor single-phasing. Have got the machine running, although it still happens...

Hey guys,

Today my HL2 hydraulic system has stopped functioning. Steps:

1. Turn machine on. Loud buzzing sound from rear/side of machine. Hard to tell if it was pump area or electrical...

Hello,

I did do a manual test too by pressing the switches with my fingers and neither switch ever delayed to respond or showed the wrong value.

After that is when I did the test I described....

Hey guys,

Thanks for the responses. We've spent the afternoon looking at the switches, and fortunately I was just able to recreate the issue. Unfortunately, I believe that rules out the switches...

Thanks for the reply. I only replaced the relays, and that was after the problem had already started. I've only cleaned the in/out switches. I will take a closer look at those on the param page...

Hello,

I have a 2000 Haas VF2 with 5811 hours on it. It has begun dropping tools on tool change about 20% of the time.
