Polar 115 EMC

We have a Polar 115 EMC that has come up with an error BRK-16 error. The key pad does not work but we can operate the back gauge back & fourth and the knife will cycle and cut.

We have tried re-seating all the boards but still no luck with getting the keypad to work. Any Idea?

UpDate
Have been advised that is should be the KC2893 board or the CP1. The cost of the two is $30,000 -$15,000. Is there anyway to trouble shoot either one of these two?

Open for suggestions on trying other things if there is something else.

Thanks for the help.

 

The communication between keyboard and main computer does not work. In this case mostly the keyboard is broken. But maybe it is just the cable. The CP-board looks good if the rest works. You have two choices Heidelberg or binderytech.com. I would ask the people from binderytech who the next good service engineer is. Good luck

 

OK got the keyboard from binderytech got the same exact error. Do you think it would be the CP1 board?

 

Can someone tell me what the voltage should be on the 5 lugs on the power supply board?

From top to bottom the readings I got are

Red - 24v
Red - 12v
Blue - .154v
Red - 5v
Blue - 0v

One other thing on the board that is behnd the key pad there is a green light that is never on.
I also checked the seril communication cable it's fine.

What should the voltage be going to the board that is behind the key pad?

TIA

Hi Jeff!

Sorry for the late answer. To much work on this side of the ocean and I think the new spare part is on the way!

Regarding the BRK-Error 16 some background information’s.
BRK-Error 16 means: after switching on the machine the main computer board CP searched for one minute the Keyboard controller. But there was no response at all.
The experience for the service engineers in the case is the following:
Mostly the board KC behind the Keyboard is broken.
In very rare situations the power supply does not work. This is the fuse F2 for 9 Volt d. c. You may check this voltage at the plug 407 pin 1 to pin 3. The plug 407 and the fuse F2 are on the very left side where the big transformer is located. You need at least 6 Volt d. c. at the plug 407. This voltage is changed on the board KC behind the keyboard to +5 Volt d. c.
Some times mice eat the cable from the power supply to the keyboard. You may check the supply voltage as well at the green plug 504 directly at the KC board as well. Therefore you measure from pin 1 to pin 4. Here you need at least +5.5 Volt d. c.
The last two possibilities are a broken data cable from the CP board up to the Keyboard and a broken CP board. But this is all theoretical. The CP board is working perfect if it comes to graphic functions. And you can check the machine functions as well. I think the food pedal is working too.
In other words mostly the board KC is broken.
The only thing which makes since is, to check the power supply for the board KC behind the keyboard and check the green plug 500. But, but, but … I do not belief in this. You will see.

The board PS supplies other components in the machine. The voltage tolerances are:
+24 Volt d. c. tolerance 23.7 to 24.3 Volt d. c.
+12 Volt d. c. tolerance 11.4 to 12.6 Volt d. c.
+5 Volt d. c. tolerance 5.08 to 5.12 Volt d. c.
For measuring you use the measurement positions in front of the board.
+24 Volt d. c. is used for inputs
+12 Volt d. c. is used for the communication between the boards underneath the table (inside the CU unit)
+5 Volt d. c. is used for the CP board and the linear scale for backgauge positioning.

If the new spare part does not work we have other chances to help. Theoretically a part at the keyboard is confusing the board KC. I never heart about this, but it should give a way of checking this as well. In other words, if we stuck somehow I will go to a EMC-Monitor machine and we are going to compare step by step the situation. For example:
Switching machine on
You get one beep from the board KC
The green LED V1 on the board KC is flashing in a frequency of one Hertz.
Etc.

Thanks for all the information. Put the parts in and had the same thing. Put my old parts back in and it still didn't work. Went to lunch and came back thought I would try it again and it worked. No idea why it started working unless by chance there is one of the wires broke.

 

Even though you’re across the ocean it's amazing how small the world really is. I have been talking to your college here in the US trying to get this figured out. Thanks for all the help; I really don’t understand what’s going on unless there is a wire that’s busted and while changing out the boards it’s in contact again but that seems unlikely since the wires wouldn’t have been distributed to begin with.

Once again THANK YOU!!!

Hi Jeff!

Maybe there was some oxidation at a plug. Your machine is a bit older now.
Not necessary how and what. The only thing which mater is the machine is working.

I hope the machine will work for some more years.

Good luck
