Safety rules

1. Read throught the instructions before you put the FCD-II into
operation. Follow all the operations according exactly to the directions
for use.

2. Keep to the directions for use and to the indications that may appear
on the FCD-II.

3. Cut off power supply before opening the connection cover or
unscrewing the front panel.

4. The FCD-II is protected according to the safety rules IP65, i.e. it is
protected against sprays of water , but only if the transparent cover is
closed.

5. The voltage must agree with the values written on the label on the
back.

6. The FCD-II is provided with a terminal for the earthwire. The
grounding must be absolutely connected.

7. The FCD-II should not be put into operation without the connection
cover (danger of wounding if the electronics is touched).

8. Cut off power supply and call a technician if one of the following
cases occurs:

- if water or other fluids have entered the FCD-II.

- the FCD-II doesn’t work correctly even though you have followed all
the instructions given. Do not try to change anything on your own;
do not press any key trying to get some reaction.

- if the FCD-II falls down and the box is damaged.

1 Introduction

The FCD-II is a precise control system with the most modern
microprocessors.

The quantity of fluids, that passes throught the installation is constantly
measured. Bar keepers don’t have to change their habits: the FCD-II corrects
the intertias present inside the flowmeter automatically .

The FCD-II has several counters that can be questioned at any time. Each
pipe can be calibrated precisely according to its use (i.e. according to the
drinks that have to be measured: beer , mineral water, pre-mix, etc...).

The access to special functions on the flow computer FCD-II is possible only
by using intelligent keys.

The FCD-II signals whenever a keg is empty by using a flowmeter provided
with foam detection. Also in the standard version a relay is avalaible with
which further alarm systems can be connected.

2 Versions

The FCD-II is avalaible in the following versions:

- control of four pipes, art. no 923-9104 (standard version)

- control of eight pipes, art. no 923-9108

- control of twelve pipes, art. no 923-91 12

- control of sixteen pipes, art. no 923-91 16
The FCD-II can be equipped with additional modules. Four additional pipes

per modules can be added. The FCD-II can contain no more than four
modules (i.e. 16 pipes).

2.1 Contents of packing (standard version)

- 1 FCD-II

- 2 cable inlets PG1 1 (art. no 699-0003)

- one for the power supply cable 230V ( 3 wires with min. section of

2

0.75mm

- one for four flowmeter cables (external diameter max. 4mm).

- 1 cable inlet PG9 (art. no 699-0002) used for the cable of the serial

interface RS-485.

- 1 intelligent key with the black ring (master key) art. no 990-0002

- 1 intelligent key with the silver ring (cleaner key) art. no. 990-0000

- 1 manual art. no 823-1001

and external diameter 6.80mm)

3 Installation

Choose a suitable place for the FCD-II and keep to the following instructions:

- the unit has to be easily reached.

- the unit has to be put at a comfortable height.

- the place has to be well illuminated (the display has no rear light)

Choose whether to install the cable inlets on the rear side or on the bottom
side of the FCD-II box.

Bottom side

Page 5

rear side

Cut out as many holes as you need on the side chosen by using a
screwdriver and a hammer . T ake one of the cable inlet s PG-1 1 in order to
connect the first group of the four flowmeters. Unscrew the nut and put the
screw into the corresponding hole and fix it. Then install the second cable
inlet PG-1 1 for the 230 V cable. If you need an interface, install the cable inlet
PG-9 as well.

Place the FCD-II as follows:
Fix a screw into the wall and hang the FCD-II on it. Open the connection

cover . For additional safety of the unit, two more screws can be fixed on its
corners.

3.1.1 Flowmeter

Number progressively each cable of the flowmeters which will be connected
to the FCD-II. Insert the cable of the first flowmeter into the corresponding
cable inlet. Take off the cable insulation for about 5 cm and strip each wire
(about 5mm).

Put each wire of the first flowmeter into the terminal as follows:
Press the white lever by using a small screwdriver (no 0 or no 1). At the same

time, insert the wire into the terminal. Release the lever.
Connect the flowmeter wires as follows:

Page 7

- green wire = terminal „-“ on Flowmeter 2

- brown wire = terminal „+“ on Flowmeter 1

- white wire = terminal „S“ (signal)

- yellow wire* = terminal „L“ (empty keg indicator) on Flowmeter 3
*Not all flowmeter models dispose of a foam indicator .
Repeat this operation for each flowmeter .
Note: the wire colours listed above are a DIGMESA-code and can be

changed.

3.1.2 Power supply

Insert the 230V cable ( a 3-pole cable with a section of 1,5mm2 is
recommended) into the cable inlet. Take off the cable insulation for about 5
cm and strip each wire (about 5mm).

Connect each wire as follows:
Phase = orange terminal
Neutral = blue terminal
earthing = green terminal
Close the connection cover , connect the flowmeters and turn power on.
