If the protection Q253 has not tripped, then either the auxiliary contact is bad or the input board is defective. If it has turned off, the inverter is most likely defective.

The errors shown on the central console have explanations on the console itself. You just need to highlight the error and press the "?" button. There is no exist general error sheet like on Bobst. Roland is not so simple.

First you need to learn how the machine works, at least theoretically. For this machine you need ITS electrical diagram. Then you can start looking for the fault. This is relay contact logic. Almost always the problem is a bad contact on a relay in a 10-20 contact circuit. I wish you good luck.

In many cases, the error is composed of several indicators. There is no common list of errors, like on a microwave oven. .....and there is no chance of becoming a service specialist with 2 pages of errors.

This red light is normal. It goes out when there is a sheet of front marks. Do you have a black display with 6 buttons? If you don't have one, the defective photocell can only be diagnosed by a qualified electronics technician on the board that controls it.

Check if there are black textile hoses (the original ones on the machine). If there are any on the feeder, replace them. They look solid but are leaking air (vacuum).

What do you mean 130lb? Thickness is what matters...

Check the RTR to HA inverter cable. And the encoder signals. !!!! RUESTEN (make ready) on the center console.

Is this a new installation or did the machine stop during operation?

If write down what happened, you will be able to seek help again without feeling ashamed.

This is a real problem, because identical boards are unusable unless the loader is changed. I can't have all the boards with all the loaders. I'm not that rich. And the loader can be changed. Now I'm trying to learn how to downgrade it.

All pictures are the same. The error address is on the second byte of the diagnostic module. 1B = 27 At address 27 is the safety bus processor board, A 358 slot 3. After replacement, it must be programmed and addressed. Navigating this process with forum posts is difficult. You need an...

The diagnosis says> Address 27 is defective. A358 Slot.3. dep Serie EA A353. SUB CAN

Check SUB CAN on EA A353 I'm sorry for the wasted time. I didn't look carefully at the diagnosis photo.

I asked if the boards were changed from one place to another. If so, which ones and where. Did the machine work normally before or is this a new installation?

The second board on the A358 is diagnostic for the safety bus. On the PU, look at the diode on the last board on the right. On all PUs it should be the same. 0.6sec on, 0.6sec off. On the in-out board, only the green diode should flash 0.6sec on, 0.6sec off. On all endbus boards, it should read...

Safety relays are something completely different from safety bus. They work after the boot phase is completed. Photo of the errors. I can't understand from written explanations.. Check the LEDs on this board in all PUs. You don't have a problem with the module processor. Somewhere the safety...

This is normal until the boot process is complete. Yours does not pass the safety bus check. Please take a picture of the error screen and the diagnostic module every time.

I suspect that the card in the A358 is defective. If you replace it, we will understand by the change of error messages. You need to buy a new one. or repair the defective one. It is also possible that there is a defect in the security processor board. There it is necessary to reprogram the new...

Replace the board in the photo with the same one from some PU. The last one on the right in A358
