COLOURED LED FUNCTIONS
GREEN LED
blinking during the normal operation
YELLOW LED
It glows when 5 V DC is present in the board
RED LED
it glows when the software is reset
(program
malfunction)
Minidip functions 1-4
REF.(20)
Coin mechanism setting 2-3
By default set to OFF
Minidip 1-8
(16)
Default configuration setting fixed to OFF
Both minidips will be eliminated in the near
future, therefore 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.
