3.2 Connecting more than one unit
Caution: perform the following operations before touching the cards in order to prevent
electrostatic discharge:
x wear the bracelet (connected to the earth circuit) and the heel strap
x the card should be closed inside an antistatic bag protecting it from electrostatic
discharge: remove it from the bag and place it on the light-blue mat with the yellow
edge or on the dark-blue mat.
x You can now work on the card.
Several intercommunicating cards can be connected together on units “L” or “XL”.
There are two connection types: “base-expansion” on the expansion serial line and “master-slave” on the
“plan” serial line. The “mixed” connection, instead, combines the two above connections. Details are
shown below.
3.2.1 “BASE-EXPANSION” CONNECTION
In the “base-expansion” connection, the entire intelligence of the unit resides in the base. The connected
expansions are exclusively used as additional I/O. The cards must be connected together with a three-
wire shielded cable connected from terminal J23 of the base to terminal J3 of expansion “E” or to
terminal J11 of expansion “M” (see figure 3.1).
Figure 3.1: “base-expansion” connection
The expansions must be given a specific address depending on the type of chiller and the enabled
functions:

3.2.2 “MASTER-SLAVE” CONNECTION
Intelligence is distributed instead in the “master-slave”
connections. Suppose we have a unit with 4 cooling
circuits: the master card manages circuits 1 and 2 while
the slave card manages circuits 3 and 4. In this case,
the additional card is not simply an input/output
expansion, but is fully involved managing part of the
unit. The card software is the same and identifies its
functions depending on the card address: the one with
address 1 (odd) will be the master and will
communicate with the card with address 2 (even and
greater). Pay special attention to card addresses for
this reason.
Connect the cards together with a 3-wire shielded
cable connected between terminals J11 of the cards,
as shown in figure 3.2.
Figure 3.2: “master-slave” connection
3.2.3 “MIXED” CONNECTION:
The “mixed” connection is used in units with 3/4 cooling circuits where an increase in inputs/outputs is
required. The master card manages circuits 1 and 2 while the slave card manages circuits 3 and 4.
Additionally, depending on the required functions or the type of machine, cards used simply as
expansions can be connected. The expansions will be connected to both the master and the slave if the
required inputs/outputs are circuit functions (recovery valves, freecooling,…). They will only be connected
to the master if they are machine functions (pumps, external air temperature,…).
Figure 3.3 shows the connections between the cards and the expansions: a 3-wire shielded cable
connects terminals J11 of the master and slave cards, and a 3-wire shielded cable connects terminals J23
of the master and/or slave cards with terminal J3 or J11 of expansions “E” or “M”.

CONFIGURING ANALOGUE INPUTS ON “S” OR “M” CARDS:
On “S” or “M” cards, the analogue inputs must be configured with dipswitches.
Analogue inputs B1, B2, B3 and B4 can be configured both as a temperature probe and as pressure
transducers; inputs B5 and B6 as temperature probes or as a digital input.

It is already built into the electronic controller on chillers with “L” cards; on chillers with “S” or “M” cards
it is already built into the Black Box card (if fitted).
Mount as follows:
1) If the clock card is not installed or is damaged, the mask shown to
the side is displayed in the “Clock” menu.

C0240111-04-05-GB
3.4 Configuring the terminals
The first operation to perform when a network is started up for the first time or an I/O card is replaced, is
to activate the procedure for terminal configuration.
This cannot be done with W3000 base. In this case, configure the terminals with a W3000 or W3000
compact terminal and then replace the display with a W3000 base.
Before starting this procedure it is advisable to check that each I/O card and each terminal has been
identified with the correct address established when the network was designed. It is important to
remember that the address set with the dip-switches or software configuration is only received if the
device is reset. RESET the device by disconnecting the power supply. Moreover, it is advisable to perform
global resetting of all network devices if a mistake has been made in the configuration of the addresses
(more than one card with the same address).
The configuration procedure can be activated from any terminal (keyboard), which may also be
connected temporarily only to perform configuration operations and removed upon completion. The
operations to perform are described in the following paragraphs.
3.4.1 SETTING THE KEYBOARD ADDRESS
After connecting the keyboard to the device (using two cables for W3000 and just one cable for W3000-
compact ) perform the following procedure:
1) Press [UP], [DOWN] and [ENTER] together and hold down until
the mask shown to the side appears.

Setting..........:00
I/O Card address:
2) Press [ENTER] to set the required keyboard address (e.g.: 21 )
using [UP] and [DOWN]
Display address
Setting..........:21
I/O Card address:--
3) This mask means that the address of the keyboard has been
set.
Display address
changed
4) If an empty mask appears, instead, it means that the keyboard
is not communicating with any card. Either the card must be
addressed or the plan network must be configured.
N.B.: This is a timed procedure; if the parameters are not set within a few seconds, the display turns off.
In this case, the operation must be repeated.
3.4.2 “S”, “M” AND “B” CARD SETTINGS
In “S”, “M” or “B” cards the card address is set by the software using the keyboard.
Proceed as follows:
1) Make sure the keyboard address is set to 0 ( see para 3.4.1).
2) Disconnect the card from the power supply (turn off the
general switch).
3) Power the card and press [ALARM] and [UP] together; hold
the keys down until the mask shown to the side appears.
pLan address: 0
UP: increase
DOWN: decrease
ENTER: save & exit
14

C0240111-04-05-GB
4) Set the required address (e.g.: 1 )
To do this, press [UP] or [DOWN]; press [ENTER] to confirm.
pLan address: 1
UP: increase
DOWN: decrease
ENTER: save & exit
5) An “empty” mask appears because the address of the keyboard
is 0 and that of the card is (for example) 1; the two devices
therefore cannot communicate. Disconnect the power supply
from the card (N.B.: the address set for the keyboard will not
be reset)
6) Set the keyboard address (see para 3.4.1): do not set it to zero
or to an address that is already used in the previously set card.
When the keyboard address is set, a blank mask appears.
7) Repeat the keyboard address setting procedure but this time
set the “I/O card address” field with the address number used
for the card. A mask similar to the one shown to the side will
appear.

8) Configure the plan network (see para 3.4.4).
3.4.3 “L”, “XL” AND “E” CARD SETTINGS
1) Make sure the card is disconnected from the power supply
2) Set the required address using the dip-switches (see below)
3) Set the keyboard address (see para 3.4.1)
4) Configure the plan network (see para 3.4.4)
In this case set the card address with the following dip-switches:

To connect several units together and remote control them, thereby forming a plan network (global),
connect a remote keyboard controlling all the plans (local).
The remove keyboard cannot be used with a W3000 base keyboard. If a W3000 keyboard is fitted to the
unit, change it with a W3000 or W3000 compact.
x CONFIGURING THE PLAN NETWORK (global):
It is easy to install a PLAN network (global). Just a few but essential operations are required. If just one
of these is not performed correctly, the entire system will not work.
The remote keyboard will work problem-free if the following operations are performed one after the
other.
1 ) Set the on-board machine card and
keyboard addresses (see configuring the
local plan network)
Leaving the network cable disconnected.
configure the terminals on each card and
keyboard (then connect the remote keyboard).
2 ) Check the chillers work correctly without
being connected to the network.
3 ) Disconnect the power supply from the
chillers
4 ) Connect all the chillers to the network
except for the remote keyboard. Connect connectors J11 together. Do not connect
the remote keyboard !!!
5 ) Power the chillers.
6 ) Check that all the networked devices work
correctly
If any faults occur, check the configuration of the
terminals to make sure that no two devices have
the same address.
7 ) Connect the remote keyboard to one of the
units (see below: connecting the remote
keyboard)
If the converter is fitted (see below: remove
keyboard from 200 to 500 metres away), make
sure the remote keyboard is powered.
8 ) Make sure the remote keyboard address is
set to 32. Follow the procedure for addressing the remote
keyboard.
9 ) Make sure that the devices outside the
chillers are correctly configured.
Make sure that no two components of the
network share the same address (to avoid
conflicts)
10) Wait a few seconds until network
communication has stabilised.
17

C0240111-04-05-GB
x If there is global network comprising just W3000 chillers, the W3000-compact can be used as a
remote keyboard. After configuring the various units (each with a different address in order not
to generate conflicts in the global network), connect the remote keyboard and repeat the
procedure.
In this case, the various machines of the network are switched by pressing [ESC] and [UP]
together.
x If the plan network does not comprise just W3000 chillers, a 16-key keyboard must be used. In
this case, press [UNIT] to switch between one card and another. In this case, however, the
terminals must be given a special configuration as the 16-key keyboard is only recognised on
“terminal 3”.
The terminal configuration procedure remains the same up to point 6 of paragraph 3.4.5, after
which:
7) The remote keyboard can be configured even if the plan
network doe not comprise just W3000 chillers. Simply
define the keyboard addressed with 32 (N.B.: on
terminal 3) as Sh, i.e.: shared.

Let us analyse a vital component for connecting several
units in a network: the “T” shunt.
This is a shunt with phone connectors (called A,B,C in
figure 3.4b).
CONFIGURATION: For our purposes, configure
terminals J14 and J15 (see Figure 3.4b). There are
several pins in each terminal. Short pins 1 and 2 with a
jumper.
