Both will be eliminated in the near
future, thus since now the
configuration is only via software
setting.
The CPU board is housed inside the
payment system compartment, on
the sliding door, and includes all low-
voltage (24 V DC) actuations, it
controls the display, the push-button
card, the photodiode barrier, the
payment system and the NTC probe
that monitors that cooling unit
temperature. The software is written
in a Flash EPROM that, by means of
a special program, can be rewritten
and updated without replacing.
It is powered from the power supply
unit through connection J15 (ref. 2)
The photodiode barrier is supplied as
standard feature in some versions,
or as an after-sales kit.
