CHARACTERISTICS OF THE REGULATION1.

The command panel of the unit allows the quick setting of the machine's operating parameters, their visualisation at any time, and the immediate summary of the machine's operating status. The display is made up of 3 figures and 4 LEDs to signal, the type of working, the visualisa-

tion of the parameters set or measured, and any alarms that have been activated. The card memorises all the settings saved with each modification and used for re-ignition after a switch-off owing to lack of voltage. With the installation of the remote control panel PR3, it is

USER INTERFACE2.

possible to control, from a distance, the turning on and off, the setting of working mode (cold-hot), and the visualisation of the alarms summary with a red indicator light (alarms).

Remote connections

• PR3

Simplified remote panel, follows the base controls that can be operated remotely from up to 30m.

CONTROL PANEL DESCRIPTION3.

Key Meaning

1 Visualisation of machine probe readings

Visualisation of triggered alarm list

3 Visualisation of operational parameters menu

4 Key to change operational parameters

5 and 6 Navigation keys

Sets the unit control, which can be local (L), from the panel on board the machine, or remote (R), from

remote panel or supervisor. The active setting is indicated by the switching on of the corresponding indicator light.

8 Sets heating  or cooling  mode;

Turns the machine on or off by setting it to STAND-BY, (only the electronic card and the electric heater are powered);

10 Cancels machine alarms and restarts it (for further information, see alarm table)

11 Led indicator of current alarms

12 Led indicator of current defrosting mode

13 Led indicator of operating compressor

FIRST TIME THE MACHINE IS SWITCHED ON

The first time the machine is switched on, it carries out a selfconfiguration operation and a series of checks through which operating parameters and electrical connections of the machine are checked. After the autotest, the company logo and

the machine type are displayed for some seconds. Then, the panel is prepared for displaying the machine probe readings (key

activated).

CONTROL SETTINGS FOR REMOTE PANEL9.

CONTROL BOARD SETTING

The command "remote" must be set on the machine control board. The timer operates either in local or remote mode. In both cases, the timer is ignored if the machine is in OFF. Moreover, the remote panel must be set to “ON”; otherwise, the machine remains off (OFF) in spite of the timer approval. The remote panel is used to manage ON/OFF and Cooling/Heating commands from a distance.

CARACTÉRISTIQUES DU RÉGLAGE1.

Le panneau de commande de l'unité permet de programmer rapidement les paramètres de fonctionnement de la machine, de les afficher à tout moment et de résumer immédiatement l'état de fonctionnement de la machine. L'écran est constitué de 3 chiffres et de 4 DEL pour

la signalisation du type de fonctionnement, l'affichage des paramètres réglés ou mesurés et des alarmes éventuellement intervenues. Sur la carte sont mémorisés tous les paramètres enregistrés à chaque modification et utilisés pour le rallumage après un arrêt pour coupure de tension.

INTERFACE UTILISATEUR2.

Avec l’installation de l'accessoire panneau à distance PR3, il est possible de commander à distance l'allumage et l'arrêt, le réglage du mode de fonctionnement (froid / chaud) et l'affichage du récapitulatif des alarmes avec témoin rouge (alarmes).
