Plug in Circuit Board 3 for Polar 72 CE 1980

Welcome auguna53,

Try these guys for local ideas on your problem. They are listed as the dealers of Polar. The basic info is

Your contact for South Africa:

SA folks would be able to ask all the right questions and should have the answers you need. CJM

The green switch on the 72 CE cutter in the main motor start switch. In side the cutter in the main power control center, (which I believe is under the cutter bed) there should be a motor starter setup. this starter has gear for 2 windings and a timer.

What should happen is this. When you turn on the main power the low voltage boards should light up. when you push the start button one of the contactors should pull in. after about 60 seconds the second contactor should pull in. if both contactors are pulling in at the same time that is bad.

I would start with that and if they are both pulling in at the same time then it is likely the start timer is either out of adjustment or needs to be replaced.

As this is an older, discontinued model there are very few parts available for it. Also you need to make sure you are supplying it with the proper voltages. If you purchased it in the USA then you are going to have to supply it with 220 v at 60Hz. these machines are very particular to voltage requirements and are usually shipped new with buck boost transformers to maintain specific voltages.

The best thing for you to do is to consult with Heidelberg and make sure of the voltage requirements for that machine. All they require is the serial number and they can give you a complete history on the machine.

If you can post a picture I may be able to tell you which contactors are the specific ones related to the motor startup.

Sorry if I am a bit vague but its been about 15 years since I worked on a Polar cutter of this model.

My apologies. you will not have the dual contactor setup on this smaller cutter. Because of the size of this cutter it pulls the main motor in a full voltage. you may need too check the fuses on the number 1 card to make sure you ar getting 24 volts to the #3 card.

but you will need to double check the main supply voltages to make sure that you are getting 220 - 240 v @ 60 Hz for sure if it is a US machine.

You have provided us with a good piece of info. I will get this info to the tech who is installing it and have him take proper action.

I will keep you posted

If you can get me some more specific information, I might be able to help more.

I have the ear of an actual Heidelberg tech and he can help me trouble shoot it with you but there may be some delay in responses.

Lets start with the supply voltage then some board pics and I may be able to help you out a bit there. All the boards should also have test points for voltages. They are usually on the edge of the board itself. They should be labeled on the board as to what the particular voltage should be at the test port. Once you have compiled all that information it should point you in the direction of the problem and isolate it to a particular board. (if it is a board problem)

The problem you will run into after that is that unless there happens to be an old board in stock at Heidelberg, you will not be able to replace it. The board itself will have to be rebuilt, and I am not sure this is a service that is offered by Heidelberg. Most components are standard but some are very specific and thus difficult to replace.

Hope this is helpful.

I need urgent diagrams electrical and Polar mechanical manual in guillotines 76, 82, 92,107, 115, 125 if you have anyone of the models copy to send urgent. Likin_davis2@hotmail.com Thanks. Greetings. David. (Lima,Peru).

Hi out there!

We are running a Polar Eltromat 72 CE since a few weeks. We have experience with a Eltromat 92, but we arent able to automate the 72. Even if we plug off the magnetic stripe, the machine has a turnaround by 28 cm. Other marks are not set and we cant set marks.

Does anybody know, on which platine (they are numbered) the eeprom for the programming-mechanism is?

Thank you in advance!

Martin
