Cat. N°: 4 149 29

4. PREPARATION –CONNECTION

(continued)

Manual action of the CA + SD:

. By the handle of the associated device.

Assembling:

. On the left side of Legrand MCB, IS, RCBO or RCCB

. No tools are required. Clipped by mean of plastic clamps on the

associated device.

. Assembling products in OFF position

. The switching device of signalling auxiliaries must fit into the

housing of the handle of the associated device.

List of allowed associations (General rules):

Three auxiliaries maximum which:

- two signalling auxiliaries

(Cat. nos 4 062 50/52/56/58/60/62/64/66, 4 149 29).

- only one control auxiliary

(Cat. nos 4 062 76/78/80/82/84/86/87).

. If signalling and control auxiliaries are associated on the same

circuit breaker, the control auxiliary must be placed to the left of the

signal auxiliary (ref. 4 062 5x / 6x or 4 149 29).

List of allowed associations (Particular rules):

. With MCB’s 1,5 modules per pole width:

- if a remote tripping auxiliary (Cat. nos 4 062 76/78/80/82/84/86/

87) is already mounted on this kind of device, only 1 module

width signalling auxiliaries (Cat. nos. 4 062 64/66) can be added.

In this set up the ½ module signalling auxiliaries will not operate.

Nothing changes for the other modular references.

. With an isolating switch DX3-IS:

- only one signalling auxiliary CA type (Cat. nos 4 062

50/56/58/62/64/66) or CA+SD (Cat. n° 4 149 29).

. With a remote trip head isolating switch DX3-IS, three auxiliaries

Link Functionality:

. This function allows you to link two EMS CX3modules to create automatic actions that, once programmed, can run independently without a

connection to a manager is needed.

The basic rule is the link between an event (circuit breaker that trip, a threshold exceeded, etc.) and an action accordingly (signalling, opening

of a circuit by motorized control or contactor, etc.).

Possible associations are:

6. SYSTEM ARCHITECTURES

The EMS CX3is a polyvalent system and, according to the needs of the customer, can be set up and/or used as “Stand-alone” or “Supervised”

system. Based on this choice the configuration and addressing methods are different.

Four possible architectures are provided:

6.1 Stand-alone system

6.1.1 with local addressing (through the track wheel)

6.1.2 with remote addressing (through a computer)

6.2 Supervised (Computer Supervisory System)

6.2.1 with local addressing

6.2.2 with remote addressing

6.1 Stand-alone system

. Stand-alone = autonomous system. To be used by the end-user if it is not necessary to have a computer for the supervision outside the

envelope. Everything can be managed on site.

6.1.1 Stand-alone system with local addressing (through the track wheel)

Local addressing advantages:

-No configuration software needed to set-up the installation

-It is not necessary to use a computer to manage settings (configurations, test, ...) and to use the system (visualize and be alerted,

...). Everything can be done through the Mini configuration module (local display, cat. no 4 149 36/37).

[Refer to the technical sheet

dedicated to this module for details]

-No communication Interfaces or gateways are required.

-Installation can be done without the intervention of a System Integrator

Programming procedure:

. For EMS CX3modules which need some: mandatory through to lateral DIP-switch of each EMS CX3 modules (see § ”Module configuration”)

Addressing procedure:

. For all EMS CX3modules: mandatory through the track wheel located on the top upper face of each EMS CX3 modules

. Marked from 0 to 9 in order to locally define the Modbus address of the EMS CX3 modules

Consequences of the local addressing mode (through the track wheel):

. Each device of the system must be addressed.

. Addresses available: from 1 to 9

. Address 0 not permitted

. It is possible to assign to several devices the same address with the purpose of grouping different functions, because they are related to the

same electrical circuit. For example, it is possible to assign the same address to a signalling auxiliary module (cat. no 4 149 29), a universal

control module (cat. no 4 149 32), a measuring module, and so on. In this way on the EMS CX3mini configuration module (local display) the

grouped function will be displayed as a unique “device” with all grouped functions.

[Refer to the schemes hereunder]

Note for the mini configuration module (local display)

. It is possible to assign it the same address as another EMS CX3through the programming menu of the device

. The mini configuration module can be placed everywhere in the EMS CX3bus

6. SYSTEM ARCHITECTURES

6.1 Stand-alone system

(continued)

6.1.2 Stand-alone system with remote addressing (through a computer)

Remote addressing advantages:

-Whole configuration (addresses and functions) can be set up through the EMS Configuration software

-Configuration software available for free

-Automatic detection of the EMS CX3modules installed in the system (characteristics, functions, configuration...)

-Increased settings possibilities: load shedding function

-Increased addressing: up to 30 Modbus addresses in a system

Programming procedure:

. For EMS CX3modules which need some: possible through the lateral DIP-switch of each EMS CX3 modules (see § “Module configuration”).

Addressing procedure:

. It is not necessary to address the EMS CX3modules. The track wheel must be left in default position “0”.

. All the addressing/configuring procedure will be done with the Configuration Software (available online for free)

. With remote addressing, the software does the automatic detection of modules installed in the system, but the supervision is not possible until

the user assigns the remote address and all the characteristics to each module.

Note: it is mandatory to connect the computer to the mini configuration module with an USB-micro USB cable.

6. SYSTEM ARCHITECTURES

6.1 Stand-alone system

(continued)

6.1.2 Stand-alone system with remote addressing (through a computer)

(continued)

Consequences for the system architecture:

-for 1 mini configuration module (cat. no 4 149 36/37)

oup to 30 EMS CX3modules (eg. 30 devices grouped per functions with addresses from1 to 30)

It is possible to assign to several devices the same address with the purpose of grouping different functions, because they are related to the

same electrical circuit. For example, it is possible to assign the same address to a signalling auxiliary module (cat. no 4 149 29), a universal

control module (cat. no 4 149 32), a measuring module, and so on. In this way on the EMS CX3display or in a supervision system the grouped

function will be displayed as a unique “device” with all grouped functions.

[Refer to the schemes here under]

Note for the mini configuration module (local display)

. It is possible to assign it the same address as another EMS CX3

. The mini configuration module can be placed everywhere in the EMS CX3bus

6.2 Supervised system (Computer Supervisory System)

. Supervised system = System to be used through a Computer Supervisory System to remotely read data from the EMS CX3devices and/or do

operations on these devices (e.g. commands of a motor driven or contactor ...).

6.2.1 Supervised system with local addressing (through the track wheel)

Local addressing advantages:

-No configuration software needed to set-up the installation

-Installation can be done without the intervention of a System Integrator

Programming procedure:

. For EMS CX3modules which need some: mandatory through to lateral DIP-switch of each EMS CX3 modules (see § “Module configuration”)

Addressing procedure:

. For all EMS CX3modules: mandatory through the track wheel located on the top upper face of each EMS CX3 modules

. Marked from 0 to 9 in order to locally define the Modbus address to EMS CX3 modules

In this system the Modbus address of an EMS CX3module device or group of modules (several functions) is obtained considering the address

of the interface Modbus/EMS CX3Interface as tenth and the address of a device or group of function as unit (e.g. Interface address 1 = 10 

address of module n°5 = Modbus address 15)
