The menus are briefly described below:

• The “Unit Menu” contains information such as temperature, pressure and circuit states.

• The “Setpoint menu” is used to set the setpoints for the various available functions.

• The “I/O menu” shows the status of the digital inputs and values read from the analogue inputs.

It also shows the status of the digital outputs and the voltage supplied to the analogue outputs.

If expansions are necessary (depending on the configuration parameters), the inputs and outputs

of the latter are also shown.

• The “Clock menu”, if the clock card is present, is used to set and display the date and time.

• Parameters relative to user programming of the unit can be displayed and set in the “User

menu”.

• The “Manufacturer menu” is used to display and set critical system parameters.

3.2 Connecting more than one unit

Caution: perform the following operations before touching the cards in order to prevent

electrostatic discharge:

• wear the bracelet (connected to the earth circuit) and the heel strap

• 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.

• 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 is a combination of the other two. 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 will be the master and will communicate

with the card with address 11 (master address plus

10). 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

C0240111-01-06-GB

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”.

3.4 Configuring the terminals

The first operation to perform when a network is started up for the first time or a card is replaced, is to

perform the procedure for terminal configuration.

This cannot be achieved with the basic W3000 keypad. In this case, configure the terminals using the

W3000 or W3000 compact keypad and then connect the W3000 basic display.

Before starting, it is advisable to check that each card and each terminal has been identified with the

correct address established when the network was designed. It is important to remember that as the set

address is only read by the boards during startup, it is best to perform a global reset of all the devices if

a mistake is made when configuring the addresses (more than one card with the same address). Reset

the network by disconnecting all the devices from the power supply .

The configuration procedure can be activated from any terminal (keypad), 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 KEYPAD ADDRESS

After connecting the keypad to the device, perform the following procedure:

1) Press [UP], [DOWN] and [ENTER] together and hold down until the

mask shown to the side appears.

4) If an empty mask or a mask showing “NO LINK” appears after

pressing [ESC], it means that the keypad is not communicating with

any card. Either the card must be addressed or the plan network

must be configured.

NO LINK

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.

C0240111-01-06-GB

3.4.2 SETTING CARD ADDRESSES

The card address is set by the software using the keypad.

Proceed as follows:

1 Make sure the keypad address is set to 0 ( see para 3.4.1). Display address

Setting..........:00

I/O Card address:

2 Disconnect the card from the power supply (turn off the general

switch).

3 Power the card by pressing [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

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 board is (as shown in the example) 1; the two devices

cannot communicate.

In any case, card address 1 has been set.

6 Now perform “NETWORK CONFIGURATION” to allow the card to

communicate with its keypad

C0240111-01-06-GB

3.4.3 CONFIGURING THE PLAN NETWORK

• CONFIGURING THE PLAN NETWORK (local):

To connect several units together and remote control them, thereby forming a plan network (global), a

remote keypad controlling all the units is required.

The remote keypad cannot be used with a W3000 basic keypad. If a W3000 basic keypad is installed on

the machine, replace it with a 3000 compact.

C0240111-01-06-GB

• 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 keypad will work problem-free if the following operations are performed one after the other.

1 Set the on-board machine card and keypad

addresses (see configuring the local plan

network)

Leaving the network cable disconnected. configure

the terminals on each card and keypad (J11

connector)

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 keypad.

Connect connectors J11 together. Do not connect

the remote keyboard. This creates a plan network

comprising more than one chiller.

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 keypad to one of the units Disconnect the machine keyboard and connect the

remote keypad to the J10 connector.

8 Make sure the remote keypad address is set to

32.

Follow the procedure for addressing the keyboard

(see para 3.4.1).

9 Make sure that the devices outside the chillers

are correctly configured.

If the power unit for the remote keypad is fitted

(see below: remote keypad from 200 up to 500

metres), make sure the remote keypad is powered.

11 Connect the remote keyboard. Disconnect connector J10 from the last board and

connect it to connector “A” of the “T” shunt.

Connect connector J10 on the last board to

connector “B” of the “T” shunt.

10 Wait a few seconds until network

communication has stabilised.

• 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.

• If the plan network does not comprise just W3000 chillers, a 16-key keypad 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 keypad 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 keypad can be configured even if the plan network doe not

comprise just W3000 chillers. Simply define the keypad addressed with

32 (N.B.: on terminal 3) as Sh, i.e.: shared.

• CONNECTING THE REMOTE KEYPAD:

• “T” SHUNT:

Figure 3.4a: photo of a T shunt

Figure 3.4b: wiring diagram of a T

shunt

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.

4 Rx+/Tx+

5 GND

6 +VRL=30V

• REMOTE KEYPAD UP TO 200 metres:

To connect a remote keypad, two “T” shunt cards must be used, one near the controller and the

other near the remote keypad, configured as indicated above. The T shunt cards must be

connected together by terminals.

1. If the remote keypad monitors just one unit, proceed as follows:

• Disconnect the connector J10 connecting the keypad on the unit with the card,

and connect it to connector “A” of the “T” shunt (see figure 3.5).

• Connect connector J10 on the card to connector “B” of the “T” shunt.

The correct configuration is shown in figure 3.5:

C0240111-01-06-GB

Figure 3.5 : connecting the remote keypad (for distances less than 200 metres)

2. If a remote keypad monitors more than one unit, the above configuration may only be

used for the last card in the network (the nearest to the remote keypad).

• REMOTE KEYPAD FROM 200 metres UP TO 500 metres

N.B.: The remote keypad cannot be installed more than 500 m away.

If the remote keypad must be installed over 200 metres away from the plan network, a power

unit must be installed near the remote keypad. The only difference between this and a remote

keypad up to 200 metres is that the power unit must be to terminals 1 and 2 of the T shunt (the

one near the remote keypad)
