CC 220 stuck in Diagnostics Mode

Hello All,

From reading the forum, it looks like a very common old problem.

Trying to help a friend to restart his old SMT flat bed lathe.

Control is a Bosch Typ1 Modul5, processor plus 2 x 32 input cards & 2 x 32 output cards in a 8 slot rack.

Cannot clear single alarm 2670 PC Time Inhibit.

Replaced the battery in the processor and the one in the Teknor front panel PC, no more locations to be found.

Copied all programs in EEPROM to RAM.

Time out parameter had a value of 100.

Any other ideas thanks?

regards...
