I am looking at a '96 Brother TC229 that my friend bought and has decided to sell it. It was reported to run reliably every day before the auction, but has had this problem since it was moved to his shop. When it first showed up they would have to cycle the main power switch on the back cabinet until the control panel power light would come on and then it would power up normally I guess. He was able to play with it a little. When I was looking at it a couple days ago we couldn't get it it to turn on. When I turn on the main switch the power alarm light/button on the control panel comes on red and it also lights up a red LED on one of the boards in the back main cabinet. I checked for anything obvious and tried to make sure cables were connected and tight. The longer I messed with it, the longer the green power light would be on before the red alarm light came on. Then it went back to going red immediately.
I did not have a meter with me to test anything. I was thinking it may be a loose connection somewhere and plan to go through things and try to unplug connections but I noticed a battery pack on it and I am afraid I may wipe the memory if I unplug the wrong thing.
Am I correct in that it has to have a battery backup for parameters?
I plan to go back with a meter and measure voltage and make sure all the fuses are good.
How sensitive to voltage variance are these? The tag says 230v.
Another problem is that it was shipped with the wrong MPG pendant. The connector on the MPG does not match the control panel connector. Is it possible to get the correct connector and repin it? Are the MPG's different besides the connectors?
I am completely new to anything Brother. I have a cnc router with a Fanuc OM and that is what I am most familiar with as far as troubleshooting etc.
Being a Brother newbie, I understand this one is a G code machine, I think the control is a CNC-820. I was told it has app 55k of memory. I have read you cannot DNC with this machine. Is that accurate? Also, how are programs loaded, is it a RS232 or something else? Having a Fanuc OM, I am used to no memory, but I can DNC to my machine easily.
Thanks for any help,
Jason
