Introduction

Ce guide d’installation concerne la section du système de commande frigorifique équipée pour communiquer avec la ligne de transmission de données LonWorks ® .

Il ne décrit que la partie assurant l’interface avec les régulateurs actuels et il étudie les deux principes de transmission LonWorks ® utilisés par Danfoss, à savoir l’interface FTT

10 et l’interface RS 485.

Les recommandations données par ce document s’adressent aux monteurs et électriciens frigoristes chargés de l’installation des régulateurs frigorifiques Danfoss. Mais les principes supérieurs de LonWorks

restent valables et ils sont disponibles dans les entreprises qui connaissent bien l’installation des réseaux LonWorks ® .

Section objet de ce guide

Ce guide étudie :

- les principes de configuration

- le câble à utiliser

- la longueur du câble

- le bouclage du câble

- la nécessité ou non d’un amplificateur

- la visibilité de chaque régulateur sur le réseau

- le procédé à suivre pour le remplacement d’un régulateur

- le procédé à suivre pour le remplacement d’une passerelle

Limitation

A l’heure actuelle, l’AKA 243 peut desservir un maximum de

60 adresses (régulateurs) sur le réseau LON. Les autres adresses (de 61 à 125) sont réservées à la section

DANBUSS. Si on a besoin de plus de 60 adresses, il faut ajouter d’autres réseaux avec chacun son AKA 243.

Les produits et leur sortie de transmission de données

Gateway

AKA 243A

AKA 243B

Il existe deux types de passerelles. L’AKA 243A est dotée d’une interface de transfert FTT 10 et l’AKA

243B d’un transfert RS485.

Régulateurs de la série EKC 200, 300

et 400.

Pont (Bridge)

Ces régulateurs peuvent être

élargis d’une carte à circuits imprimés comprenant soit FTT

10 ou RS 485

Le pont comporte une connexion

FTT 10 et une connexion RS 485

Amplificateur

Le programme ne comprend actuellement pas d’amplificateurs. Cette fonction s’obtient avec deux ponts montés dos à dos.

Principes

Cette page présente les principes des deux formes de transmission de données, leurs câbles de liaison et l’utilisation respective d’amplificateurs.

FTT 10 ou RS 485 ?

Il appartient à l’utilisateur de choisir la forme de transmission, mais le facteur déterminant est souvent le prix qui depend de la configuration de l’installation et du nombre de régulateurs. Il faut évidemment tenir compte des autres composants

LonWorks

que l’on désire ajouter à l’installation.

FTT 10

• On peut installer le câble de façon pratique pour l’installation en question. Les dérivations de toutes sortes sont admises.

• Longueur maximum du câble : 500 m.

• Nombre maximum de régulateurs AKA 243A non comprise est 60.

• Si la longueur totale des câbles d’une distance partielle dépasse 500 m, il faut installer un amplificateur.

RS 485

Combinasion

Amplificateur

Pour la configuration avec FTT 10, se reporter aux pages 4 et suivantes.

• Installer le câble de façon à relier les régulateurs en série.

Il faut éviter les bifurcations.

• Longueur maximum du câble : 1200 m

• Nombre maximum de régulateurs AKA 243B non comprise est 60.

• Si la longueur totale des câbles d’une distance partielle dépasse 1200 m, il faut installer un amplificateur.

Pour la configuration avec RS 485, se reporter aux pages 6 et suivantes.

• On peut combiner les deux types au moyen d’un pont.

• Le nombre maximum est toujours 60.

• Un pont n’a pas d’adresse

• Respecter les contraintes de chacun des deux types.

FTT 10

Câblage

Type de câble

Pour obtenir une transmission satisfaisante des données, il faut que le câble soit conforme aux spécifications émises par l’ECHELON Corporation. En voici les critères les plus importants :

Utiliser un câble à paires de conducteurs torsadés, de préférence avec blindage. La section du conducteur doit être de 0,60 mm au moins.

Exemples de câbles à utiliser :

- Belden 7701NH unifilaire 1 x 2 x 0,65 mm, non blindé

Belden 7702NH unifilaire 2 x 2 x 0,65 mm, non blindé

Belden 7703NH unifilaire 1 x 2 x 0,65 mm, blindé

Belden 7704NH unifilaire 2 x 2 x 0,65 mm, blindé

LAPP UNITRONIC Li2YCY(TP) multifilaire 2 x 2 x 0,65 mm, blindé

Dätwyler Uninet 3002 4P unifilaire 4 x 2 x 0,6 mm, blindé

Le câblage est au choix et les bifurcations sont admises.

Eloigner le câble des sources de nuisances électriques et de leurs câbles (les relais, les contacteurs et surtout le « ballast

électronique » des tubes fluorescents sont de puissantes sources de bruit électrique). Un écart de 10 à 15 cm au moins convient.

Il faut amplifier le signal pour chaque 500 m de câble. Il faut au maximum 250 m entre un régulateur et une passerelle ou entre un régulateur et un amplificateur.

Veiller à relier les bons fils du câble au régulateur. Même avec

4 conducteurs dans le câble à l’intérieur du blindage, on ne peut pas choisir les couleurs facilement. Les fils sont torsadés par paires, et il faut absolument utiliser une paire de fils torsadés ensemble.

En cas de plusieurs fils « disponibles » dans le câble, il ne faut les utiliser que pour la transmission de données.

Embouts des câbles / Bouclage

a a b

Pour obtenir une transmission satisfaisante des données, il faut respecter certains principes pour les embouts des câbles et leur bouclage.

Ne dénuder que la longueur de câble nécessaire. Poursuivre la torsade des fils jusqu’aux bornes.

Relier un blindage éventuel à la passerelle et aux amplificateurs s’il y en a.

Lorsque tous les câbles ont été installés sur les différentes unités, il faut boucler le câble.

- a

Pour la première distance reliée à la passerelle, on courtcircuite le contact à cavalier situé près de la borne. Ceci s’applique uniquement si aucun des branchements en étoile ne dépasse 250 m.

(Le contact à crochet d’une AKA 243A se boucle à 52,3 ohm.)

-b

Si des amplificateurs sont installés, il faut également boucler la distance subséquente. Pour ceci, installer une résistance unique à travers les fils du câble. On peut installer les résistances à n’importe quel point du câble. Noter la valeur de la résistance.

- c

Si une distance de câble dépasse 250 m, le bouclage doit

être double, c’est à dire qu’il faut installer une résistance à chaque bout du câble.

Les autres distances en étoile éventuelles ne sont pas à boucler. Noter la valeur des résistances. Il faut ouvrir le contact à crochet.

(On peut accepter que les résistances 52.3 ohm aient une valeur comprise entre 50 et 60 ohm.)

(On peut accepter que les résistances 120 ohm aient une valeur comprise entre 100 et 130 ohm.)

- Dätwyler Uninet 3002 4P unifilaire 4 x 2 x 0,6 mm, blindé

Le câblage se fait de régulateur à régulateur, et les dérivations ne sont pas permises.

Eloigner le câble des sources de nuisances électriques et de leurs câbles (les relais, les contacteurs et surtout le « ballast

électronique » des tubes fluorescents sont de puissantes sources de bruit électrique). Un écart de 10 à 15 cm au moins convient.

Embouts des câbles / Bouclage

Amplificateur

Pour obtenir une transmission satisfaisante des données, il faut respecter certains principes pour les embouts de câbles et leur bouclage.

Ne dénuder que la longueur de câble nécessaire. Poursuivre la torsade des fils jusqu’aux bornes.

Relier un blindage éventuel à la passerelle et aux amplificateurs s’il y en a.

Lorsque tous les câbles ont été installés sur les différentes unités, il faut boucler le câble.

- Une distance de câble à RS485 est obligatoirement bouclée aux deux bouts.

- Pour la première distance reliée à la passerelle, on courtcircuite le contact à cavalier situé près de la borne.

(Le contact à crochet d’une AKA 243B se boucle à 120 ohm.)

- Les autres bouts de câbles sont bouclés au moyen de résistances.

(On peut accepter que les résistances 120 ohm aient une valeur comprise entre 100 et

130 ohm.)

Exemple

Ici, un régulateur unique est installé dans une armoire. Se méfier de l’écart entre le câble et le régulateur. Le système le considère comme un bras de réactance de la ligne de transfert. Assurer un écart convenable par rapport aux relais, leurs câbles et tout autre élément émetteur de bruit électrique.

Exemple

Ici, plusieurs régulateurs sont installés dans une armoire.

Utiliser un câble toronné – entre les régulateurs aussi.

Un amplificateur pour un transfert RS485 peut être généré par deux ponts.

Régulateurs EKC

Adressage

Après installation des régulateurs, il faut signaler à la passerelle qu’ils sont prêts à fonctionner sur le réseau et lui communiquer leurs adresses. Procéder comme suit :

1) Le menu o03 de chaque régulateur permet d’inscrire une adresse. Une adresse est un numéro entre 1 et 60.

2) Pour porter cette adresse à la connaissance de la passerelle, passer au menu suivant (o04) et le régler sur

ON. Le régulateur apparaît alors à la passerelle (message de service).

3) Au bout de 30 secondes environ, la passerelle envoie l’adresse choisie pour affichage sur le régulateur EKC.

Si par erreur on choisit la même adresse pour deux régulateurs ou plus, le premier seulement est visible pour la passerelle.

Remplacement

Après le remplacement d’un régulateur sur le réseau, il ne faut pas oublier de lui donner la même adresse et de la communiquer à nouveau à la passerelle. (Ceci s’applique même si le module LON reste en place.)

Après un changement de passerelle, les adresses EKC sont importées à l’aide d’une fonction de lecture dans la passerelle

(fonction utilisée à la place de la fonction « o04 »).

La fonction est enclenchée en utilisant la console AKA 21 ; elle s’appelle « Press Enter to scan LON bus » (appuyer sur

ENTER pour importer bus LON).

Introduction

This manual provides a description of the configuration and operation of the m2 functions relating to the EKC 210/301 controllers only. For a full description of all the standard m2 functions, refer to Manual m2 -

RS.8A.N.

The m2 has the facility to communicate 2-way with the EKC 201 and

EKC 301 controllers. This enables the following facilities via the m2 unit: display and modification of defined controller setup parameters.

provides alarms generated as a result of readings returned by the controller (local), or alarm reporting as a result of alarm states detected by the controller itself (remote).

Principle

Shown on this page is the principle of the data communication and wiring to the controllers.

Validity

This document was made in May 2001 and applies to m2 software version B2.0 onwards.

Controller Point Setup

m2 Communication with EKC201/301

When a EKC controller is logged onto a m2 system, whatever the controllers address is parameter (o03) will be automatically be assigned as the point number on the m2. This will include overwriting any previous settings set to that point number.

Ensure before logging a EKC controller onto a m2 system, that the address set is available in the m2. If not available then change the address on the controller.

To configure a controller point, the controller must first be logged on, after which select the Point Setup option from the Setup menu and select the point number of the EKC controller. The controller

Point Setup screen is as displayed.

The controller point setup screen differs from the standard point setup screen as follows:

Introduction

This manual provides a description of the configuration and operation of the m2 functions relating to the EKC 331 capacity controller only. For a full description of all the standard m2 functions, refer to Manual m2 -

RS.8A.N.

The m2 has the facility to communicate 2-way with the EKC 331 capacity controller. This enables the following facilities via the m2 unit: display and modification of defined controller setup parameters.

provides alarms generated as a result of readings returned by the controller (local), or alarm reporting as a result of alarm states detected by the controller itself (remote).

Principle

Shown on this page is the principle of the data communication and wiring to the controllers.

Validity

This document was made in May 2001 and applies to m2 software version B2.0 onwards.

To view the Controller Point Detail Screen is the same procedure as a standard Point Detail Screen. The Controller Point Detail

Screen is displayed as shown.

There are five information areas that are displayed. These areas display the following information: this area will display icons indicating the status of the controller, the icons being of the following:

- fans on

- compressors on this indicates the compressor or condenser pressure.

this indicates whether the point has been setup for 'Local' or 'Remote' alarms.

- Local

- Remote

This area also displays 'inhibit' and

'inhibit pulldown' icons, if the point has been setup for 'Local'.

- an inhibited point.

- a point in inhibit pulldown.

Indicates the upper alarm limit setting. When the of the symbol is scrolling, it indicates that the upper alarm limit has been exceeded.

Indicates the setpoint setting.

Indicates the lower alarm limit setting. When the part of the symbol is scrolling, it indicates that the lower alarm limit has been exceeded.

Controller Point Setup

When a EKC controller is logged on to a m2 system, whatever the controllers address is parameter (o03) will automatically be assigned as the point number on the m2. This will include overwriting any previous settings set to that point number.

Ensure before logging a EKC controller onto a m2 system, that the address set is available in the m2. If not available then change the address on the controller.

Point Setup screen is as displayed.

The controller point setup screen differs from the standard point setup screen as follows:

Type

This field is automatically set when

(Setting the Point Type)

the controller is logged on and therefore must be adjusted.

Defr PDown

(Defrost Pulldown)

This field is not used.

Alarms (Setting the

Alarms Source)

LOCAL

Use this field to specify the source of the alarms. The two settings are:

REMOTE

This will set the m2 to report alarms as a result of alarm states detected by the controller, and allow the controller to manage defrost lockout.

The point setup screen will differ depending on whether the point has been set to 'Local' or 'Remote'. The differences are as follows: m2 Communication with EKC331 Manual RS.8A.T1.02

Controller Point Setup (Screen 2)

The guide recommends using twisted pair cables with shielding for optimal data transmission. Examples include Belden 7701NH, Belden 7702NH, Belden 7703NH, Belden 7704NH, LAPP UNITRONIC Li2YCY(TP), and Dätwyler Uninet 3002 4P.

The maximum cable length for FTT 10 is 500 meters, while the maximum length for RS 485 is 1200 meters. Amplification is required for longer distances.

Each EKC controller can be assigned an address between 1 and 60. The address is set on the controller itself and must be communicated to the gateway.
