2. Ingredient Coefficient Sub-Program
There is an ingredient coefficient value for each ingredient allocated to a canister in
the canister configuration sub program (Vision 300/400 only). The ingredient
coefficients are used to determine the weight of each ingredient used.The formula used
in the calculation is:-
I
ngredient coefficient x ingredient quantity = hundredth's of a gramme of ingredient in drink
This formula enables an accurate count of the weight of each ingredient used to be
logged, using information found in both the Operators and Engineers weight counters.
Although the machines are pre-programmed with preset values for all the ingredient
coefficients, these values may vary with ingredients from different manufacturers and
may not be accurate for the particular ingredient being used. More accurate coefficients
may be calculated in the following way:
1. Set the ingredient quantity time to 100 in the drink sub program.
2. Using a suitable container, collect the dispensed ingredient for the drink type
at the dispense nozzle of the canister.
3. Accurately weigh the ingredient in grammes, taking into account the weight of
the container used.
4. Round the weight to the nearest whole number to give the ingredient
coefficient. As an example, if the weight of ingredient using a dispense time of
100 was found to be 57.84 grammes, the ingredient coefficient would be 58.
Note: The accuracy of the weight counters is entirely dependent upon the accuracy
of the measurement of ingredient used to determine the ingredient coefficient.
Crane Stentorfield can accept no responsibility for the accuracy of ingredient
coefficient values supplied by any other party.
3. Output Test Sub-Program
This sub-program enables the engineer to individually test each output of the machine.
1. On entry into the sub-program the LCD will display the first output (Inlet Valve),
with its present state (off) beneath it.
2. Pressing the arrow keys allows the engineer to cycle through the outputs in turn,
displaying the name of each one. In order to test an output, press the “1” key to
switch it on, and the “0” key to switch it off. The caption at the bottom of the
LCD will show the current state of the output. If the output is left ‘ON’ for more
than three seconds the protection circuit will switch it ‘OFF’, even though the
