active (flashing)
– The main page displays the active power currently used in the system, the active power percentage with respect to the rated value for the system and the total active energy meter for the system.
– The user can choose the page and sub-page that the DME D305T2 display returns to automatically after a certain time has elapsed without the buttons being pressed.
– It is also possible to program the energy meter so that the display always remains that which was last selected.
– For the setup of these functions, see the P02 – Utility menu.
FRONT METROLOGY LED
– The red front LED pulses 10,000 times for each kWh of energy consumption, referred to the CT secondary.
– The flashing frequency of the LED provides an immediate indication of the amount of power required in a given moment.
– The duration of the flashing, the colour and the intensity of the LED comply with the standards that prescribe its use for metrological checking of the energy counter’s accuracy.
VIEWING OF MEASUREMENTS
– The
s and t buttons allow the measurement display pages to be scrolled one at a time. The current page can be recognized through the unit of measurement shown in the top part of the display.
– Some measurements may not be displayed, depending on the programming and the connection for the device (for example, if programmed for a system without neutral, the measurements relating to neutral are
not displayed).
– For every page, the button permits access to sub-pages (for example, to display the maximum and minimum values recorded for the selected measurement).
– The sub-page displayed currently is indicated at the bottom right by one of the following icons:
– IN = Instantan ous valu – Current instantaneous value of the measurement, displayed by default every time the page is changed.
– HI = High st p ak – Highest value measured by the energy meter for the corresponding measurement. HIGH values are stored and preserved even in the absence of a power supply. They can be reset through a
dedicated command (see command menu).
– LO = Low st p ak – Lowest value measured by the energy meter from the moment voltage is applied. It is reset with the same command used for the HI values.
– AV = Av rag valu – Time-integrated (average) value of measurement. Permits display of a measurement with slow variations. See Integration menu.
– MD = Maximum D mand – Peak integrated value (max demand). Remains stored in non-volatile memory and can be reset with a dedicated command.

ENERGY METER INDICATION
– There are five dedicated pages for energy meters.
• Imported and exported active energy
• Inductive or capacitive reactive energy
• Apparent energy.
– Each page displays the total and partial value (can be reset from commands menu).
– If the unit of measurement is displayed continuously, it means that the meter is for imported energy (positive). Display of exported (negative) energies can be enabled as well by setting parameter P02.09 to ON.
These energies are highlighted by the flashing of the unit of measurement and by the “-” sign, and are displayed after the imported energies by pressing
t .
– If display of energy by individual phase is enabled (P02.10=ON), three independent additional pages, one per phase, will be displayed, including total and partial energy.
– If programmable input P13.01 is set to TAR-A, all the energy meters indicated are also present divided by Tariff 1 and Tariff 2. These meters are displayed in the system meter sub-pages (see Tariffs paragraph).
TARIFFS
– For energy metering, the DME D305T2 can manage 2 independent tariffs in addition to total and partial.
– The tariff is normally selected through the digital input, or optionally through messages sent through the communication protocol.
– To select the 2 tariffs, the TAR-A input function is available. Activating this makes the selection illustrated in the table:
– The device features a VAC programmable input.
– The default function setting is TAR-A, which therefore permits selection between the two tariffs 1 and 2.
– The text tAr-1 or tAr-2 flashes to indicate the selected tariff and consequently the meter reading that is increasing.
– The meter readings for the tariffs are displayed as a sub-page of the system meters (total and phase if enabled).
– The active tariff can be selected through a dedicated command on the Modbus protocol (see Modbus protocol technical instruction).
HOUR COUNTER INDICATION
– If the hour counter is enabled (see menu P05), the DME D305T2 displays the hour counter page, with the format indicated in the figure:
– There is a total hour counter and 4 partial hour counters that can be reset and activated with different sources (see the parameters of the P05 group).

LIMIT THRESHOLD STATUS INDICATION (LIMx)
– If the limit thresholds are enabled (see menu P08), the DME D305T2 displays the page, with the corresponding status and the format indicated in the figure:
– With limit threshold activated, the word ON flashes, while if it is deactivated the word OFF is constant. If no limit threshold is programmed, dashes are displayed.
ALARM INDICATION
– If alarms are enabled (see menu P09), the DME D305T2 displays the page, with the corresponding status and the format indicated in the figure:
– With alarm activated, the word ON flashes with the triangle symbol, while if it is not activated the word OFF is constant.
– If no alarm is programmed, dashes are displayed. After about 3s, the scrolling text of the alarm programmed in parameter P09.n.05 appears.
– With several alarms active, the texts are displayed in succession.
– Dedicated parameter P02.14 for the utility menu can be used to make the display backlighting flash in the event of an alarm to highlight the presence of the fault.
– The alarm reset method depends on parameter P09.n.03. This determines whether it can be automatic, on the disappearance of the alarm conditions, or requires manual intervention through the commands menu
(C.07).

(clignotante)
– La page principale affiche la puissance active actuellement appliquée dans l’installation, le pourcentage de la puissance active par rapport à la puissance nominale de l’installation et le compteur d’énergie active
totale du système.
– L’utilisateur peut spécifier sur quelle page et sur quelle sous-page l’écran DME D305T2 doit revenir automatiquement après un certain délai, sans avoir à appuyer sur des touches.
– Il est également possible de programmer le compteur d’énergie de manière à ce que l’affichage reste toujours dans l’état où il a été laissé.
– Pour le réglage de ces fonctions, voir le menu P02 – Utilitaire.
LED MÉTROLOGIQUE FRONTALE
– La LED rouge frontale émet 10 000 impulsions par kWh d’énergie consommée, se référant au secondaire du TA.
– La fréquence de clignotement de la LED donne une indication immédiate de l’importance de la puissance nécessaire à un moment déterminé.
– La durée du clignotement, la couleur et l’intensité de la LED sont conformes aux normes qui prévoient son utilisation aux fins d’un contrôle métrologique quant à la précision du compteur d’énergie.
AFFICHAGE DES MESURES
– Les touches
s et t permettent de faire défiler une par une les pages d’affichage des mesures. La page en cours peut être détectée gr ce à l’affichage de l’unité de mesure dans la partie supérieure de l’écran.
– En fonction de la programmation et du branchement de l’appareil, il est possible que certaines mesures ne soient pas affichées (par exemple s’il est programmé pour un système sans neutre, les mesures indiquées
pour le neutre ne seront pas affichées).
– Pour chaque page, la touche permet d’accéder à des sous-pages (par exemple, pour afficher les valeurs maximales et minimales enregistrées pour la mesure sélectionnée).
– La sous-page en cours d’affichage est indiquée en bas à droite par une des icônes suivantes :
– IN = Val ur instantané – Valeur instantanée actuelle de la mesure, affichée par défaut chaque fois que l’on change de page.
– HI = Val ur maximal instantané – Valeur la plus élevée mesurée par le compteur d’énergie pour la mesure correspondante. Les valeurs HIGH sont enregistrées et conservées même en l’absence d’alimentation.
Elles peuvent être remises à zéro à l’aide de la commande appropriée (voir le menu des commandes).
– LO = Val ur minimal instantané – Valeur la plus basse mesurée par le compteur d’énergie à partir de la mise sous tension. Elle est remise à zéro avec la même commande que celle utilisée pour les valeurs HI.
– AV = Val ur intégré – Valeur de la mesure intégrée (médiate) dans le temps. Permet de voir une mesure avec des variations lentes. Voir le menu Intégration.
– MD = Val ur intégré maximal – Valeur maximale de la valeur intégrée (max demand). Elle reste enregistrée dans la mémoire rémanente et peut être remise à zéro avec la commande appropriée.
