Section 2
Programming
INTRODUCTION
1. The Vitro S2/3 Beverage Machine provides two discrete user programs: The Operator’s
program and the Engineer’s Program. The Operator’s Program is available to both the
Operator and the Service engineer, but the Engineer’s Program is only available to the
SERVICE ENGINEER.
2. Both the programs are stored in programmable read only memory on the Controller Board.
The values and settings (Variables), which the program allows the programmer to alter, are
stored in NVRAM (non-volatile random access memory).
3. Settings are maintained, without the need for back-up battery, when the power supply is
removed.
