Schneider Senator 115 knife not acting

[Vahagn Ayvazyan]

It was worked good before, after installation at new place it stopped working. After switching on it shows software version error.

Then everything works fine but the knife is not acting.
Please help

Hi sir:

Test 1) in the main board Regulated Power Supply : + 5 +12 -12 Vdc in tolerance 0.7% up or down otherwise replace or repair it>!

2) Power board : + 24 Vdc + 42 Vdc in tolerance 0.7% up or down.

 

[Vahagn Ayvazyan]

Thanks for reply, do I need to check power supplies? And what about software version error?

 

[CHOCK]

Do First testing the Regulated Power Supply.

Any indication From faulty Power supply is good indication possibility, from error codes.

However if everything is ok, we go to another Steps!

Blessings

We checked power supplies, there is no 10v and 12v on the trasformator, all other is ok

 

[Vahagn Ayvazyan]

Also after some disassemble and reassemble of the circuit boards we could operate the knife few times but after shutting down and restart it stuck again

 

[CHOCK]

I did indicate you that test First very well: Regulated Power Supply for VDC!! In Tolerance!!!

Let me know, Check , for : loose wires, connectors corroded, pins broken or bent, dirty

Clean Electronic cards,the Edge connectors with Eraser pencil, very well, and then clean with Spray electronic cleaner!! This represey , the 75% of failure in electronic job,!!!

Look, card: dry+ Colder joint solder!!!

Ok, we replaced power supplies, checked all connectors, all circuit boards, nothing wrong, I think some safety system blocking knife operation. When pedal pushed, holder comes down and when we push two buttons only brush motor clutch clicking and nothing happens.

 

[CHOCK]

Test the + 42 VDC x clutch electromagnetic, clean very well brush or replace it, clean the ring or clutch.
Clutch possible overheating, ( not burning,), but imply that must be winding again, if everything is ok.

Test the cut button x, loose wires, or faulty cut button.

Look if the system have security bolt, and test the voltage, according with the schematic wiring electrical: + 24 or ,+ 42 VDC.

Let me know

Blessings.

Clicking sound is from cutting length setting motor, I checked it works fine, button wires also checked, the buttons also work fine, when pushed only that clicking sound from length motor clutch acting, then nothing happens, only once after few checking we turned on the machine and it worked fine, we made several cuts then we shut it down and turn again it won’t cut again

 

[CHOCK]

Test: the safety Bolt: + 42 VDC
Test if when you press the cut button: +42 VDC is there in :1); safety Bolt 2) clutch electromagnetic???ok.

3) See the brushes are good??
4) ring of clutch electromagnetic must be cleaned very well.
5) try too to adjust the Gap From clutch.

Let me know ASAP

Blessings

Can’t understand what safety bolt? Can you show some pics? Which brushes do you mean? The clutch gap is not adjustable, it fixed and have no issues

Hello every one.
Dear Senior member, Mr CHOCK

I have the same problem such as this. and very sad to say I bought this machine as a second hand one without Electrical diagram and wiring schematic.
Same problem exactly. The same sound: I hear the click sound while i touch two touch-response keys and nothing, i should kindly add When pedal pushed, holder comes down and when we push two buttons only brush motor clutch clicking and nothing happens. And a RED LED at delta-star switch, lights up while it turns on Delta position.

Thank you very much and regards

P.S. model 115mc-v year 1991

Hello Sir,
First of all, I hope it finds you very well. Hereby I would like to express my special gratitude for your being here and of course you kindly support the others. I appreciate.
And for these below valuable mentioned objects:

Test: the safety Bolt: + 42 VDC
Test if when you press the cut button: +42 VDC is there in :1); safety Bolt 2) clutch electromagnetic???ok.
3) See the brushes are good??
4) ring of clutch electromagnetic must be cleaned very well.
5) try too to adjust the Gap From clutch.

I am far from machine right now, but very happy to receive your above data and support. Tomorrow hopefully I would be at printing house. But for your kind information We bought this machine as a second hand machine from the Netherlands after shipment we understood it hasn't any manual or catalogue in package, neither Electrical drawings Nor mechanic nor spare part list nor what ever. may I kindly ask you if you have its electrical manual please send it to me by Email andy.muller10(at)yahoo.com otherwise it would be extremely difficult to recognize what is what.
Thank you again and happy to hearing from you.
Regards

It seems that on electronic board 4110 which has a testpoint for +42vdc doesn't exist. its indicator LED is off and in the other word 42 volt-4110 card is lost. I need a manual for detailing more.
3) brushes are good.
4) Ring of electromagnetic clutch is clean
5) didn't understand what you mean by GAP/

Dear Mr. Chock,

I hope it finds you very well and very kindly I would like to express my special gratitude for your very friendly support and being informative. I appreciate. With the people such as you the world be a better place.

As you may know, it was extremely difficult to allocate this problem without electrical drawing manual.

But with the help of you and the others I find at least the problem that why after holder, the blade doesn’t come down.

I would like to share this valuable experience with fellow who still have Schneider Senator paper cutting machine.

There are 3 important relays “K1, K2 & K3” at electronic control box. And their contacts need to be cleaned. Most Important point is that these relays visually look like each other. Sockets on board are same too, but from electrical view the inner contacts aren’t same. So after service if they be installed incorrect (at wrong position) blade doesn’t come down and 42vdc will not traceable. Hope it be enough clear to understand for the others.

Best regards
Andy
