Push-button board layout and connections
Machine control board configuration
The machine control board is designed as an integral part of the control system, therefore comprising the CPU
and the actuations by means of relays and triac. It was conceived to be used in different machine models.
It is configured at the factory by means of Minidips and Jumpers. In the event of replacement it will be necessary
to check that the new board configuration is suitable for the required use.
To check its configuration proceed as follows:
A series of minidips (Ref. 3) are located at the centre of the board permitting its configuration for use in the
different versions and countries. A Jumper (Ref. 2) is used to configure either Espresso or Instant.
The board also has provisions for supporting 512 Kb and 1 Mb EPROM’s by setting Jumpers JS3 and JS4.
