so ive had this 15n (T32b)for 6 months or so. was all dead and parameters gone when i got it ,plus a bad board in the panel. once i fixed all that, all was good. made a few parts. etc. most recently it sat for 2 months. i fired it up other day and im back to square one. params all gone again. i reinitialized and got back going and all is good , but WHY did it lose memory in only 2 months? are there more than the one battery i see in left of cabinet with 3.6 V? that battery still tests out at 3.75V by the way. i just want to find the cause of whatever is causing this,as i do not wish to have to go through setting tools and cutting conditons all over again for a 3rd time . lol
 
I know that my QT250 has the backup battery in the panel, in the rear with all the circuit boards and such. But also, I found one behind the screen. Try looking around in there. It was the same battery as the rear panel one so hopefully this helps you!

if its the same one, it should be easy to find. so far, ive not seen or heard of where it would be. really didnt wanna start pulling all the cards out , but what worries me is if theres not another one. lol
 
think i got to the bottom of it i hope. started it up today. parameters ALL gone AGAIN. checked battery today, and its dead as a hammer. its showed 3.75 the 4 times ive checked it so far, in and out of the machine. new battery on the way, and hopefully this is done happening.
 
SO, its been a couple years. had some board/connection and screen issues and kinda got aggravated and let it set for awhile. got the screen and everything fixed. My question is , how long can these machines set with the power off and not drain the backup battery? seems like if i went more than a couple weeks, bam, battery is dead and all the parameters are gone. does anybody know if thats a normal timeframe on these or is there another issue?
 
well. i reinitialized everything....AGAIN....so ill see how long this lasts this time. i cant ever really use this machine, cause it sucks trying to reload every dang cutting condition, and tool library ,etc. its not worth the time if it wont keep any of it.
 
gotcha. good info. ive also found it indeed does charge if control is on. but thats definitely not an option for me. i was just curious what is a normal time for it to sit idle without going dead? ive not ran across a machine that does this before. my other mill sat a whole year and is fine as long as i keep good batteries in it. i have also been tossing around the idea of a 3vDC 110v trickle charger to keep things up while it sits cause i just dont use it much. but probably would if i can tackle this issue. ive found a bunch of 3vdc power supplys but not having any luck on trickle charger yet

yeah. that would be easy enough to accomplish. im just trying to find out first what the standard discharge time should be to see if i even have an issue before i go trying to change things around

Tha'ts what i did. Mounted a power point inside the cabinet and wired it to the hot side of the main switch so it is powered even with machine off. Hooked the 3.7v side to the 3 batteries (M42 control) No more battery problems

How did you select the correct power point?

I'm sure this is a rather elemtary question, but there's quite a bit at stake.
 
Bring your battery to the nearest Allstate Battery place and have them re use the leads to make up a more robust battery pack. I have done that before and just needed to find a parking spot for the new battery pack. And sure the owner of a machine I shipped to a new home has found a much bigger battery pack swinging by its wires in the control cabinet.

yeah. thats really not an option, cause there will be no power available as im running a phase converter and its not on unless the lathe is
 
so, yesterday, i noticed the battery voltage went up a tad if i pulled out the m116 card. so i left ot out last night. the battery today didnt seem to lose any voltage. i plugged the card back in and when i turned everything back on, all my parameters,etc are still fine. so maybe ill just pull that card if i leave it down awhile

Just come of any one phase of your main switch. The power point i used is the standard home type that you would plug any electrical item into. Obviously you need to connect neutral and earth to it as well

so, youre saying use a 110 outlet to power it. but how are you getting 3.7v out of that?
 
I have a Mazak M32B, on the documentation the battery is given for 3 months.

A technician told me for another machine that old components consume electricity.

As for the larger battery, I asked the question here, and someone told me that this wasn't necessarily the solution, as the machine wouldn't be able to recharge a larger-capacity battery.

Another topic

My machine has a 12V battery for the M32 system.
This battery only lasts 3 days, but it doesn't cause the settings to be lost. You just need to charge the floppy disk on start-up,
do you also have this problem?

thats the info i was looking for. thats much better than the 2-3 weeks i was getting. i do happen to have two of these batteries though. i dont see why if i stack them, it wouldnt double the life and the machine would still charge it just fine, although may take longer.

but, no. my battery was lasting between a week and 3 weeks if i remember right. but if its dead, i lose EVERYTHING. which has caused me not to be able to run the machine much cause its too much hassle.

but i just had something happen while messing with it. i started getting a bus error on startup, which is why i shut it down last year. well, it started working one day. but then it did it again the other day. i had a spare 116 card, so i swapped it, and it instantly came up working. and since then, ive monitored the battery and it is still holding at no less than 3.7V. so maybe ive accomplished something here finally. machine is currently working as intended. in a week or 2, i may get brave enough to start really putting some tool data and offsets in for good hopefully and be able to actually do something with it .
