Hercules Pro startup and than nada

[typenut]

Hello all, made Film yesterday and today: turned the Hercules Pro on, the Floppy shows up on display twice as usual and than it's like the power got cut to the display, nada.

Where do I start to look?

Hello,

Hello, the problem may be a back-up battery for RTC and RAM memory on the motherboard (slot A04).

To verify this, you'd have to connect VT100 imagesetter interface with a computer with any terminal program. VT100 is a RS232 serial port, you just make a cable. Imagesetter-off shows on the terminal screen, which in turn starts and what happens. If you get an error time and date, it will cause the battery.

Sorry for my English, I use a translator

I also have the same problem.The machine boots flashes Linotype twice then goes off.Anybody with a quick solution will be highly appreciated.

I can fix it, but I can not do it at a distance. This requires the electronics board to send to me.

Which Board exactly,we have the MAINCONTROLLER board at slot A04, there is the EC CONTROL board, then the entire H-MOTHERBOARD.Which board exactly.I will really appreciate your efforts.

Thanks

It's about the entire Motherboard in slot A04. There is no longer manufactured integrated circuit with a battery that needs to be cleverly replace. And then reset the configuration and enter the new parameters. Not a very simple operation (sorry for my english)

Morning,
You should check the ECC board.
Good luck

Not again! the ECC board, I thought the ECC board Controls the Exposure Head, Rotating Mirror Unit and Material Width Recognition.How is connected to the booting of the imagesetter. Please expain further.
Most regards.

Please read this: The Main Controller controls all operations in the recorder. The Operating System, pSOS+, is resident in an EPROM on the Main Controller.
Operating System
pSOS+ is a real time multitasking system that dows priority tasking. For instmce, Video
data is assigned a higher priority than Graphic Data, so video data is processed fist. pS0S+
uses the filesystem pHile, similar to UNXX. At Power on, the Main Controller loads pSOS+
From the EPROM and the recorder data from the floppy disk into the RAM on the Main
Controller and executes instructions as required. The recorder is then initialized.

First question: is the boot disk is ok? If not, the machine will not boot properly. A floppy disk that can normally be read in the ordinary PC.

Without connecting the VT100 terminal will not be able to easily find fault - imagesetter communicates at boot, showing all the errors.

Your failure, however, indicates the most to damage the battery. If the imagesetter detects damage to the battery will not run properly.
