Polar Mohr 76 EM error 69 and english manual
We bought Polar 76 Em and we repair the power drive of the motor and the machine is works. But we haven't got any manual of this machine and we can't program the machine. If you share the english manual or explain to us how we can store program
i- with a cutting sequence
ii-without cutting sequence
iii- how can we modify the stored sequence
iv- how can we delete stored program
v- whats the cause error 69 and solution
and other valuable information us we will be pleased.
You can download the manual from Polar 76em Manuals Downloadables
Error 69 means:
During a read-, write- or erase-function within the program memory bank a data error was discovered.
The next step should be to find somebody who is able to Polar cutters in a correct way.
An alternative is to take boards from another machine and try it in your machine. This allows you to determent which board you finally need.
Please watch out there two different types of 76 machines in the market. One version has 9 programs and the later machines have 99 programs. The operating manual and the spare parts have to fit to your machine. Maybe you know the machine number? It should be xx61xxx.
is it trusted site?
I read your message and thanks for your information. I want to be sure if given link is trusted site because it looks like warez site and they don't show and sample pages to us if it is correct manual/s. Can you give detailed information to us.

For the another spare machine i can just say no. because we don't have same barnd and model here. our machine has a 9 main program and we can store different 99 program under this 9 main program.
EAI board polar 76em
On the EAI board we had -30, -12, -30 and -12 volts on the test point are ok. all of the fuses on the left power pcb are ok. on eai board we had nec 8255a-5 ic, and er3400i rom ics. i want to speak on this rom ics. is it just store the paper cut positions / or it is stores the machine software in it? the pcb is shows polar 016191 on it. The machine number is 5261236. Mod 1983 76 EM. The software version is V2.0 and it is shows on PCB cabinet and some ics.

You have a machine with 9 programs. Do you have an Email-address?
The measurements are o. k. Because you measure with active power supply.
But the two voltages -12VB and -30VB have to be active for (2-3 seconds) after switching of the machine. The letter “B” stays for buffered.
The board PMR (power module rectifier) is maybe not working correct. If the power supply switches off to fast the machine is not able to write the last information into the memory.
You have two choices. The buffered voltages given by the board PMR are not correct or the memory board EI is broken. A correct service engineer does never fix boards of a cutting machine. This would be illegal by international low!
thanks for your message. my email address is firstname.lastname@example.org
Did you measured the voltages again?
An service manual would not help you in this case.
i measure the power module on left hand side. 406, 407 and 405 ports when i read the values it looks like ok. and at the same time i changed the rectifiers which one is screewed on heat sink. the problem is still same.
