4.00 Controller software

4.01 Menu structure

4.02 Code number

Sensitive settings are protected by a code number. The software distinguishes between different access levels, however, so that not all menu options can be accessed by entering a single number. The code number input is basically the same for all areas. Since the dispenser is not equipped with a numeric keypad, the input is performed using the plus and minus key.

Input example:

For the purposes of our example, we will use the code number 3241.

First press the Enter key (E) until the message text (FSD V1.xxx) appears. Do not release the key yet!! Always begin your input with the plus key, pressing it until the respective digits of the code number are reached. In this example, press the plus key 3 times [3241] (keeping the Enter key pressed all the time!). Then press the minus key twice [3241], then the plus key 4 times again [3241] and finally the minus key once more [3241]. Only now can you release the Enter key. The entered code number (3241) will now be evaluated by the controller. If the number is correct, you will now find yourself in the menu at the appropriate access level.

The code numbers for the individual access levels are not given in this manual but are communicated to you separately.

9

4.03 Editing menu options

You can move through the menu with the +/- keys. If you wish to change a value, press the

Enter key. The cursor will now begin to flash, and you can change the desired values by pressing the + or – key in order to increase/decrease the selected digit. To move from one number to another, use the arrow keys. Once you have entered the value, save it and exit again with the Enter key.

To exit the menu (i.e. quit the input function), press the + and – keys SIMULTANEOUSLY.

5.00 Variable parameters

The same pump parameters are available for all 4 pumps. The description of the parameters therefore only refers to the general operating principle and not any one particular pump. To change the values of the individual pumps (feeders), select the menu option with the corresponding feeder number (L1,L2,L3,L4).

5.01 No. of pulses per 100ml of syrup

Fitted to the motor shaft of the pump is a sensor which measures the number of motor revolutions. This sensor guarantees that the dispensed beverage always contains the same amount of syrup. By entering the number of pulses per 100ml of syrup, it is possible to calibrate the pump to a different feed hose or differently tuned gear.

The syrup pulses are adjusted at the factory and do not need to be readjusted except during servicing!

5.02 No. of pulses per litre of water

The flow rate of the water is measured with the aid of a liquid turbine. This sensor guarantees that the dispensed beverage always contains the same amount of water. By entering the number of pulses per litre of water, it is possible to adjust the system to a different type of turbine.

The water pulses are adjusted at the factory and do not need to be readjusted except during servicing!

5.03 Mixing ratio

With this type of dispenser, you can enter the mixing ratio of your beverage numerically. Since the flow rate of the water and syrup is recorded by sensors, a constant mixing ratio is guaranteed at all times regardless of any fluctuations in the water pressure. The mixing ratio is entered in the form of the number of parts of water per part of syrup, i.e. a mixing ratio of 4,0 means 4 parts water to one part syrup per beverage size.

5.04 Portion size

The dispenser is equipped with a keyboard at the front. In each feeder section, there are 4 keys for dispensing the product. The top three keys are used to dispense portions of different sizes.

The portion sizes can be defined individually: simply enter the dispensed volume in ml.

11

5.05 Manual limitation

At the bottom of the product dispensing keys you will find the Manual key. Press this key if you want to dispense the product without portioning. Dispensing will stop as soon as you release the key. In order to prevent a product from being dispensed continuously due to a faulty key or the removal of more product than allowed, the dispensed volume is limited to the value set here.

Please note that the Manual key interrupts the portioning procedure. If the operator has selected one of the 3 portion sizes accidentally, he can therefore stop the dispensing process by pressing the Manual key.

5.06 Water pre- and post-feed

In order to dispense syrup-based beverages, a small amount of water has to be dispensed before the syrup itself. This is designed to prevent the syrup from sticking to the bottom of the glass and thus ensures a more even distribution.

The water post-feed is designed to ensure that the syrup is fully rinsed out of the mixing spout in order to prevent a build-up of germs.

Please enter the appropriate pre- and post-feed volumes here in ml.

If you are not sure which pre- and post-feed volumes to enter, please contact the responsible service department.

5.07 Language

The device can be set to 3 different languages. If your language is not covered, please contact the responsible service department.

5.08 Product dispensing operations

The number of product dispensing operations is stored in a non-volatile memory. This value is recorded separately per feeder for each beverage size. The total throughput for a particular feeder is also recorded. Not all of these values are displayed in the menu: to check all the values, please use the PC software.

Note on memory:

In order to extend the life of the internal memory module, the data are not loaded into the non-volatile memory after every dispensing operation, but are initially stored in a buffer. The control system only saves the data to the backing memory if no product is dispensed for 5 minutes or no saving takes place for an hour. If you want to make sure the data of the last dispensed beverage are saved, wait approx. 5 minutes before removing the mains plug.

The setting data cannot be lost, as they are transferred to the backing memory immediately on input.

12

5.09 “Empty” monitor

A bag size can be entered for each product feeder. The dispensed volume of product is then subtracted after each dispensing operation. When the residual volume reaches zero, the feeder in question is blocked after the dispensing operation and a corresponding message is generated. The LED of the Manual key also lights up at the same time, so that you can tell from a distance that the feeder is no longer in action.

Whenever you insert a new bag in the device or replace a bag which was not completely emptied, you must always reset the counter for the bag size. To do this, press the Enter key and the Manual key of the relevant feeder SIMULTANEOUSLY until the reset message appears

(approx. 5 seconds) and the LED of the Manual key lights up.

To suppress the bag monitoring function, set the bag size to zero.

5.10 Motor protection

The computer determines the required motor rpm ( = motor impulses) on account of the incoming water impulses and the passed on syrup impulses. The motor rpm collapses with a heavy-working pump. The torque, which is necessary to move a heavy-working pump rpm-adjusted, climbs over the max. torque of the motor (Overload). The safety device prevents an overload of the motor by an adjustable max. permissible motor-pulse-width for an adjustable time between 0,5 and 4 seconds.

The maximum pulse-width is set at 100 % and the maximum time at 1 second by the plant.

This safety device prevents damages at the pump motor, which can result from dirt or faults at the pump.

6.00 Display

When the adapter box is connected to the display, the word “LOCK“ appears in the display, and all information is relayed to the PC. In this case, the display is no longer used for display or input purposes.

If a PC is connected to the display, the keyboard is also locked. The device is then operated via the PC software.

13

7.00 PC connection

The PC connection offers quick access and is a convenient way of editing all device parameters except for the temperature.

In order to connect a PC, an interface converter is used (optional).

Please do not try to connect the dispenser without this adapter under any circumstances, as this may destroy the PC interface.

7.01 Connecting the PC

• Install the FSD Control program on your PC. This is performed via an installation routine.

• Connect the interface converter (Fig. 1) to the PC

• Open the service cover in the door of the dispenser (Fig. 2)

• Plug the PC connecting cable into the interface (Fig. 3 + 4)

Fig. 1 Fig. 2

7.02 Reading out parameters with the PC

The parameters are transferred to the PC by pressing the “Readout“ button.

Readout

7.03 Editing parameters with the PC

Change the parameters according to your requirements, then save the data in the dispenser.

Save

The parameters may only be changed by trained personnel !

15

8.00 Temperature adjustment

The temperature is adjusted via a thermostat at the rear of the device. For this purpose, remove the rear panels (13.01 Opening the rear panels). The factory setting is approx. 3 degrees

Celsius. The set temperature is the water temperature; the cooling chamber temperature is approx. 1.5 degrees Celsius above this value.

9.00 Drainage of condensation

The built-up condensation is channelled to the drip tray via a hose system. Please check the drain hose to make sure it is never blocked or covered.

10.00 Bag container

In order to ensure safe storage of the syrups inside the device, the syrup bags are placed in the bag containers.

Open the bag container

• Place the syrup bag in the container so that the dispensing spout can be inserted through the hole in the container

• Push the bag adapter into the retaining device

• Close the bag container

11.00 Inserting the bag containers in the device

Insert the bag containers in the device so that the hoses make contact with the pump.

16

12.00 Pumps

The wave-like motion of the pump frame causes the syrup in the hose to be pumped to the dispensing spout in measured doses.

Take care to keep the pump blades clean. Juice concentrate between the blades will distroy pump and gear!

12.01 Opening the pump

The pump cover can be released by pushing the open button at the side.

12.02 Inserting and connecting the feed hose

After opening the pump, insert the feed hose in the pump housing.

• Mount the dispensing spout on the water nozzle

• Close the pump

• Open the dispensing spout by rotating it half a turn to the right

17

12.03 Water flush

This key on the pump is used to flush the syrup out of the mixing spout completely in order to prevent a build-up of germs.

Only activate the water flush once the dispensing spout is mounted and pointing downwards !

13.00 Maintenance

13.01 Opening the rear panels

The rear panels of the device can be removed without the use of a tool. They are removed from the retainer by simply pulling them out from behind.

Never operate the device with the rear panels removed!

Ventilation of the condenser is only possible when the rear

panels are mounted!

13.02 Cleaning

Only use mild detergents and a damp cloth for cleaning.

The water cooling element and water-conducting components may only be cleaned with beverage dispenser approved detergents.

If the pump-lamella is dirty, it is necessary that the pump is dismantled and cleaned into warm water by the service.

Do not allow any moisture to get inside the device.

13.03 Cleaning the condenser

The condenser should be cleaned of the accumulated dust at regular intervals (half-yearly). For this purpose, remove the rear panels and vacuum-clean the condenser from below.
