BOARD FUNCTIONS
CPU BOARD
The board is arranged on the sliding shelf
and intended to manage the machine op-
eration.
The board has got a Flash EPROM, which
means that it can be electrically re-written
(e.g. for a software update).
Some leds on the board supply the follow-
ing information
-DL1: yellow led, which means 5V applied
-DL2: red led on, which means that the
board has been reset
-DL3: green led, on during the operation of
the board
-DL4: green led, which means 24V applied
