Auto Lost Program

[Logoman]

Came into work this morning fired up the Auto, power came on but nothing would happen. Called M&R to get them to trouble shoot it. Well possibly needs new Battery and Re-programed. Never heard of that but took the PLC out and put on UPS to get er done. We are busy as Hell and now I am down an Auto, that stinks. Any one else had this problem?

I have had a battery go out & the press would not index. But if I remember correct we could manually print heads,  luckily I keep a backup on hand.  That's not a good feeling.

that can and will happen. In the owners manual it tells you a schedule on battery changes. Did it fail before the allotted time which I am guessing as I don't know which press We are discussing of around 2/3 years?

rich, we had an older gauntlet (1999) and the tech couldn't find the battery, we never replaced it, did some of the presses have plc's that didn't require batteries?

Around that time there was one series Gauntlet that had a FXON microprocessor that did not have a battery. but only that one. All else had at least one.

I've had the battery go out on both my MHM's but it doesn't lose the program, only the settings (flash times, which heads are turned on,etc.) when you turn
it off. Do modern PLC's still lose their ladders when the battery goes?

[mk162]

we must have had that one.  any reason you didn't use that one in anything else?  I prefer not having a battery to remember to change.

I'm not sure, but I THINK MHM would use custom PCB's to control the press. I think Anatol does this as well because there isn't a PLC in my machine, but there is a proprietary PCB main board and I think it has a battery but doubt it would lose settings if the battery dies.

I'd wager that %99 of machines newer than the old Americans (and maybe the Tuf's?) use PLC's. My MHM's have Hitachi PLC's
which have proven incredibly reliable. I can even back the program up just in case. Or to make modifications if I ever learn
ladder programming...

If no battery you would need a more expensive e-prom That is sensitive to static and operator error if installed improperly. Trust me you want the battery.

Anatol is in the 1% then!  Wonder if any other manufacturers are PLC-less. First guess would be RPM?

The difference is how the PLC stores the programming volatile or nonvolatile. Some need constant voltage to retain some if not all the programming hence the battery, some just need it just for parameters most newer units its nonvolatile so loss of voltage should not effect it like your desk top less the battery.  I have a pad printer that the battery is week (can't change it, sealed unit) if left unplugged for more then 30 days it will loose the parameters, if this happens I just pull the cover and enter the correct parameters and move on.

I don't know for sure what our machine uses but I'm pretty sure it doesn't have a battery.  If it does have a battery I don't know where it is and it's lasted 5 years so I'd assume if it did it would have gone dead by now. 

We had our Centurian for 3.5 years and we didn't change out a battery on it during that time so I don't know if it had one or not.
