Polar EMC 92 memory saving problem - Please help

I got a problem with newly arrived polar EMC 92 (memory card detachable machine, with 99 programs and 999 cuts, white color buttons with lamps inside)

Its a weird problem and have never came across like it before. That is, "the cut sizes are not saving". the weird thing is, when I press the Record (The "Dot") button, its not saving the size and not giving any error message too. just like I've not press the button. I checked the button contacts and its ok. the memory card is recognized by the CPU. the leftmost display is showing [1 0]. I can change program number with P+ and P- but not the cut number with S+ and S-. there seems no any burnt ICs, it seems the software purposely not saving the sizes. (its somewhat like saving function is turned off) all other functions are working fine (clamp, blade, positioning, etc...)
what will be the problem? anybody came across with this kind of problem before?

and I'm also curious about the two switches on the N-KB card. could not figure out their functionality.

Please help me and I'm very helpless.

Thanks in advance

 

You have a EMC 1. This machine was build from 1980 to 1981 (in case of 92). This machine is 30 years old and not just arrived. There are no more spare parts available. Mostly the memory banks inside the removable memory box (N-WS) are gone. The left switch is changing between metric and inch display. The right switch is showing the internal compensation during backgauge stop (give you nothing).

You could try replace the battery inside the memory bank (N-WS) and try refresh it by erasing all the programs(1-98),hope it helps.

Hi dsgraphic

Not so easy.
First of all. The older colleagues said that if there was a time without power supply the memory is broken. The risk to fix the memory bank just by changing the battery is high.
The only idea I have - ask binderytech.com or gsm-schneidsysteme.de in Germany.

Hello NimeshSilva, did you have any luck fixing this problem? I am having the exact same problems and need help too. Thanks

 

Dear megaman,

My problem was with the memory box. Can solve it by replacing the memory box or the memory ics inside the box. And don't forget to check the battery voltage too. (if you have necessary skills to do it). But apart from that, your problem could be due to burnt ic in some other card too. Please check it out.

Hope this helps.
