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 prescri e its use for metrological checking of the energy counter’s accuracy.
VIEWING OF MEASUREMENTS
– The
s and t uttons allow the measurement display pages to e scrolled one at a time. The current page can e recognized through the unit of measurement shown in the top part of the display.
– Some measurements may not e 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 utton permits access to su -pages (for example, to display the maximum and minimum values recorded for the selected measurement).
– The su -page displayed currently is indicated at the ottom right y one of the following icons:
– IN = Instantaneous value – Current instantaneous value of the measurement, displayed y default every time the page is changed.
– HI = Highest peak – Highest value measured y the energy meter for the corresponding measurement. HIGH values are stored and preserved even in the a sence of a power supply. They can e reset through a
dedicated command (see command menu).
– LO = Lowest peak – Lowest value measured y the energy meter from the moment voltage is applied. It is reset with the same command used for the HI values.
– AV = Average value – Time-integrated (average) value of measurement. Permits display of a measurement with slow variations. See Integration menu.

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 e 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 e ena led as well y setting parameter P02.09 to ON.
These energies are highlighted y the flashing of the unit of measurement and y the “-” sign, and are displayed after the imported energies y pressing
t .
– If display of energy y individual phase is ena led (P02.10=ON), three independent additional pages, one per phase, will e displayed, including total and partial energy.
– If programma le input P13.01 is set to TAR-A, all the energy meters indicated are also present divided y Tariff 1 and Tariff 2. These meters are displayed in the system meter su -pages (see Tariffs paragraph).
TARIFFS
– For energy metering, the DME D305T2MID 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 availa le. Activating this makes the selection illustrated in the ta le:
– The device features a VAC programma le input.
– The default function setting is TAR-A, which therefore permits selection etween 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 su -page of the system meters (total and phase if ena led).
– The active tariff can e selected through a dedicated command on the Mod us protocol (see Mod us protocol technical instruction).
HOUR COUNTER INDICATION
– If the hour counter is ena led (see menu P05), the DME D305T2MID 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 e reset and activated with different sources (see the parameters of the P05 group).

ALARM INDICATION
– If alarms are ena led (see menu P09), the DME D305T2MID displays the page, with the corresponding status and the format indicated in the figure:
– With alarm activated, the word ON flashes with the triangle sym ol, while if it is not activated the word OFF is constant.
– If no alarm is programmed, dashes are displayed. After a out 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 e used to make the display acklighting 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 e automatic, on the disappearance of the alarm conditions, or requires manual intervention through the commands menu
(C.07).

– Na hlavní stránce se zobrazuje činný výkon, který se právě používá v soustavě, procento činného výkonu ve srovnání se jmenovitým výkonem soustavy a počitadlo celkové činné energie systému.
– Uživatel má možnost určit, na jakou stránku a podstránku se má displej DME D305T2MID automaticky vrátit po uplynutí času bez stisknutí tlačítek.
– Počitadlo energií lze naprogramovat i tak, aby zobrazení zůstalo tam, kde bylo zanecháno.
– Pro nastavení těchto funkcí viz menu P02 – Utility.
ČELNÍ METROLO ICKÁ KONTROLKA
– Přední červená kontrolka vysílá 10 000 impulzů za každou kWh spotřebované energie vztažené na sekundární vinutí PT.
– Četnost blikání kontrolky poskytuje okamžitou indikaci velikosti výkonu požadovaného v daném okamžiku.
– Interval blikání, barva a intenzita svícení kontrolky odpovídají normám předepisujícím použití těchto kontrolek pro metrologickou kontrolu přesnosti počitadla energie.
ZOBRAZENÍ NAMĚŘENÝCH HODNOT
– Tlačítka
s a t umožňují procházet jednotlivými stránkami pro zobrazení naměřených hodnot. Aktuální stránka se pozná podle zobrazené měrné jednotky v horní části displeje.
– Některé hodnoty nemusejí být zobrazeny: to závisí na naprogramování a připojení přístroje (jestliže je například naprogramovaný pro systém bez nulového vodiče, nezobrazí se hodnoty pro tento vodič).
– Na každé stránce umožňuje tlačítko přístup na podstránky (například pro zobrazení maximálních a minimálních hodnot zapsaných pro zvolené měření).
– Běžně zobrazená podstránka je ukázána dole vpravo jednou z následujících ikon:
– IN = Okamžitá hodnota – Okamžitá stávající hodnota se defaultně zobrazí při každé změně stránky.
– HI = Maximální okamžitá hodnota – Nejvyšší hodnota naměřená multimetrem pro příslušné měření. Hodnoty HI H se uloží do paměti, kde zůstanou i bez napájení. Lze je vynulovat příslušným příkazem (viz příkazové menu).
– LO = Minimální okamžitá hodnota – Nejnižší hodnota naměřená multimetrem od připojení napětí. Resetuje se stejným příkazem jako hodnot HI.
– AV = Integrovaná hodnota – Hodnota integrovaného (zprostředkovaného) měření v čase. Umožňuje zobrazit měření s pomalými změnami. Viz menu Integrace
– MD = Maximální integrovaná hodnota – Maximální hodnota integrované hodnoty (max demand). Zůstane v energeticky nezávislé paměti a lze ji resetovat příslušným příkazem.
