GENEVA - Vending Machines

COFFEtek Ltd
Set Product Constants
24. The Geneva control system maintains a counter for the amount of each ingredient consumed. For
these counters to work correctly the throw rate in grams per second actually dispensed from each
ingredients canister must be input. One way to determine the correct value is to catch the
ingredient dispensed during ten vends of a particular type and then divide the weight of
ingredients so dispensed by the auger run time figures set for that vend. For this to work all scale
factors must be set to 100.
If the ingredient counters are not required, this facility can safely be ignored. The values entered are
for audit purposes only and do not affect the drink formulations or machine operation in any way.
Machine Status
25. Entering MACHINE STATUS provides access to the status of the following machine features:
• TEMP STATUS
• 1 2 C HEALTH
• MEMORY USAGE*
• SOFTWARE VERSION
(a)
TEMP STATUS
This display provides information relating to the heater control circuit. A power (PWR) level
value and a graphical representation of the drive waveform to the heater are displayed. The
temperature reading in degrees centigrade derived from the thermistor probe in the water boiler
is displayed along with the analogue-to-digital converter value from which the temperature was
calculated is parenthesis.
(b)
I 2 C Health
This display provides information relating to the I 2 C serial link between the Controller and RIO
Boards. A percentage 'health' reading is given, indicating the success rate of communication of
the link. A reading of less than 100% may indicate the presence of electrical noise. The number
of negative acknowledgements (NACKS) is also recorded.
(c)
Software Version
These displays indicate the version of the software installed on the Controller Board. (Program
+ EPROM = Firmware.) The firmware version should be quoted when seeking advice.
(d)
FRAM Faults
This checks to see how many times the program has tried to write to the non-volatile
memory should always been at (0), this is a program to check for faults that are occurring in
the machine.
