    Arrow Siemens "alarm 40-33 output/fuse failure on APC rack 0"

    I have Arrow with Siemens Control. In the rack, I have DV5 servo board and Profibus DP Card. RT board is G7VP2. I lost bios settings after replace BIOS battery. When I set two interrupts IRQ7 and IRQ15 to ISA in the RT BIOS menu, the machine is undergoing diagnostics. All tests is passed but I have error "alarm 40-33 output/fuse failure on APC rack 0". Has anyone solved this problem? Does anyone have Flash and BIOS settings for RT G7VP2?

    Serwis we reflash these using a binary program and floppy disk; then test the board in a simulator with a special I/O Board tester. The pn on the inside lip of the RTCPU board chassis is 3-424-xxxxAyy. This is what someone would need to know to perform the settings.
