Groups
When the units are enabled, each time the unit code is selected the vending machine enables a unit spiral
(the choice of which spiral of the unit to be enabled is made on a rotation basis involving all spirals of the
unit to guarantee equal use).
The unit creation mechanism is based on the assignment of the selection code (product identification
number) to more than one physical motor.
By default, each motor is associated with the code corresponding to the motor itself.
Therefore, motor XY will be enabled following selection of the code XY.
The technician may vary this situation by assigning a different code to each motor.
By assigning the same code XY to more than one motor, a unit of motors is created with XY as their
selection code.
Enabling of a unit affects statistics, independence, etc..
The "STATISTICS TABLE" summarises all the effects.
When units are disabled, each motor works only after the default code is selected.
Example
Assuming that drawer 2 has 5 spirals and we want to sell the same product in the first 3 spirals, using the
single selection code 121 for this.
The following prices are assigned
Product 121 --> price = 0.10
Product 122 --> price = 0.20
Products 123, 124, 125 --> price = 0.30
We go to the code assignment menu (menu "Unit codes").
Select motor 121.
By default, we have: motor 121 assigned to code 121.
M121 --> 121
This is fine. 121 will be our main unit selection.
We now move onto motor 122 and set it up in such a way that it is assigned not to code 122, but rather
to code 121.
From
M122 --> 122
We go to
M122 --> 121
The same applies for motor 123
M123 --> 121
We do not modify motors 124 and 125
M124 --> 124
M125 --> 125
We enable unit management (menu "Unit enabling").
Now, by selecting product 121, the vending machine will supply a product using spiral 121 (at a price of
0.10).
A second selection of product 121 will lead to the supply of a product from spiral 122 (at a price of 0.10).
If we select product 121 three more times, we will obtain supplies from spirals 123, then 21 and finally 122
(always at a price of 0.10).
If product 122 or 123 is selected, it will be classed as 'not available'.
By selecting product 124, we obtain a product from spiral 124 (at a price of 0.30).
Statistically, the results are for 5 supplies of product 121, 1 supply of product 124 and 0 supplies for all
others.
Faulty motor example:
Should one of the unit motors report an error for any reason, this motor is disabled and the error recorded
in the error LOG. The unit will continue functioning as before, but less one motor.
Motor 122 reports an error.
--> The LOG records an error for motor 122 --> and motor 122 is disabled.
3 selections of product 121 lead to the supply of the product from spirals 121, then 123 and then 121
again.
Unit deactivation example:
If we deactivate the units, selecting code 123 leads to the supply of product 123 at a price of 0.30.
