Подключение УЗО компании Legrand

Назначение устройства защитного отключения ─ защита человека от удара током, а электротехники – от токов перегрузки и короткого замыкания. Они предотвращают утечку тока, возгорание кабеля в случае короткого замыкания и выход из строя электрооборудования при нарушении работы сети. При этом схема подключения УЗО проста и эффективна.

Требования пожарной безопасности требуют установки устройств защитного отключения в жилых, торговых, офисных, промышленных помещениях. Многие заводы-изготовители с мировым именем выпускают надёжные устройства по цене от 1500 рублей. Французская компания Legrand – один из таких производителей. Она выпускает автоматы линейки DX с рабочим током до 80 А.

Схема подключения УЗО Legrand

Производитель предусматривает три правила подключения:

• включать только после вводного автомата;
• исключить прохождение нулевой фазы и фазы цепи, которую нужно защитить;
• использовать только оригинальные детали и элементы.

УЗО Legrand нужно подключать в распределительном шкафу, предварительно включив электрический счётчик. Это нужно для того, чтобы обеспечить надёжную защиту оборудования при коротком замыкании, перебоях в сети. Недостаток этого способа в том, что при неполадках в сети обесточится вся электросистема. Для предотвращения такой ситуации нужно подключать аппарат на участке, где могут возникнуть перебои сети.

На рисунке изображена однофазная схема подключения УЗО. При включении устройства в трёхфазную сеть схема будет аналогичной, но с небольшими отклонениями.

Чтобы убедиться в исправности УЗО, нужно проверить его в тестовом режиме. Если этого не сделать, устройство не выполнит свою работу и возгорания не избежать. Работоспособность оборудования Legrand проверяют кнопкой «Тест». При её нажатии имитируется неисправность сети, которая вызывает срабатывание оборудования. Если аппарат сработал мгновенно, значит, он находится в рабочем состоянии.

Старая электробытовая техника, осветительное оборудование вызывают утечку тока на корпус. Это провоцирует частое срабатывание УЗО. Поэтому для повышения пожарной безопасности рекомендуется при установке защитного оборудования стоит проверить все приборы, устранить неисправные, заменить сломанные узлы и детали.

Цена устройств защитного отключения Legrand зависит от:

Перед покупкой УЗО стоит чётко определить задачи и функции, которые оно должно выполнять, решить, потребуется ли вспомогательное оборудование.

Подскажите по подключению УЗО Легранд.

Не сочтите флудом. У электрика проблема с УЗО говорит не рабочее..взял домой проверить.
Но на удивление на УЗО нет обозначения где фаза а где нуль .(( это нормально ?
Подключать по классике слева фаза справа ноль ?
Заранее спасибо!

Если обозначений нет — значит ему пофигу, можно и так и так.
Ткните ему провод с вилкой и на Тест нажмите — должно отшибить.

да
фирма-производитель и модель у того УЗО есть?

Написано же в названии темы — Легранд. 30 мА 40 А

А самому загуглить официальное изображение данного устройства слабо?
модель, я так понимаю, LR 2-полюсная? Мы тут все экстрасенсы. модель сообщать нет необходимости.
Данная модель не имеет полярности, то есть ей пофиг справа/слева и снизу/сверху
А вообще, у Леграна N обычно справа, если вам это интересно.

УЗо ведет себя странно. подсоединил на вход фыазу с нулев и воткнул в розетку. Тест срабатывает. Но на выход фаза не приходит..

значит контакт обгорел. Такое возможно, если УЗО не было грамотно защищено вышестоящим автоматом.
Если отключить УЗО от сети взвести, то оба полюса не прозваниваются?

Не все работает в плане тока Это видно старая вилка плохо подходила к розетке..сейчас в другую пробовал и случайно рукой тронул фазу -довольно сильно щепнуло. а УЗО не сработало..толи 30 мА много толи легранд подкачал..в воде если стоять 30 мА мало поможет..получается надо 10 мА брать на всю квартиру ?

У меня в хрещевке нет земли, как проверить на утечку его ?

если б сильно щипнуло, то вы бы тут с нами не общались. Человек чувствует ток порядка 2-3 мА, значит удар был в районе 3. 29 мА — УЗО и не должно было отключиться.

jud-suss написал :

Значит пусть будет 30 мА мы всегда его ставим по стандарту.Но тут читал тему ч то человека в ванной ударило, стояло 30м А у него нога отказала)) ..поэтому в ванну 10 мА ставим..правда его хрен где найдешь..

В это что криминального ? Ложные срабатывания будут ?

jud-suss написал :
В это что криминального ? Ложные срабатывания будут ?

да. Очень вероятно. Может даже не дать включить вообще — будет отключаться мгновенно. Ориентировочно можно оценить ожидаемый ток утечки:

ПУЭ
7.1.83. Суммарный ток утечки сети с учетом присоединяемых стационарных и переносных электроприемников в нормальном режиме работы не должен превосходить 1/3 номинального тока УЗО. При отсутствии данных ток утечки электроприемников следует принимать из расчета 0,4 мА на 1 А тока нагрузки, а ток утечки сети — из расчета 10 мкА на 1 м длины фазного проводника.

УЗО может срабатывать в диапазоне 1/2. 1 от номинала, поэтому ожидаемый ток утечки и не должен превышать 1/3 от номинала. Чтоб быть уверенным что ложных срабатываний не будет

Если в квартире 200 м проводки и нагрузка 25 А, то 200*0,00001 +25*0,0004= 10 мА , то есть, УЗО с номиналом 10 мА обязано сработать, а УЗО с номиналом 30 мА обязано не сработать.

Схема подключения проходного выключателя Legrand

Проходные выключатели выглядят как обычные, но схема их подключения немного отличается от традиционных устройств. Ничего сложного здесь нет, но у пользователей иногда возникают трудности. Чтобы окончательно разобраться в вопросе, прочитайте эту статью. В ней подробно описано подключение выключателей проходного типа Legrand. Помимо этого, вы узнаете принцип работы подобных устройств и их виды.

Что такое проходной выключатель

Если у вас дома находится лестница на другой этаж, приходится подниматься по ней в темноте или оставлять включенным свет, ведь для того чтобы выключить его, нужно спуститься вниз. Это относится и к длинным коридорам. Конструкция проходного типа позволяет включать свет в одном месте, а выключать в другом. Выгода от ее установки очевидна. Традиционные устройства только замыкают и размыкают контакты. Проходные модели состоят из одной общей и двух перекидных рабочих линий, поэтому и управлять ими можно из разных точек.

Почему Legrand

Это крупнейшая компания, продукция которой считается в России одной из самых популярных. Была основана в 1866 году и с тех пор обрела огромный опыт в производстве различных изделий для электросетей. Для изготовления выключателей и других продуктов используют качественный фарфор. За производством следят на каждом этапе, чтобы все компоненты были долговечными и удобными в эксплуатации. Сегодня продукция компании Legrand представлена более чем в 60 странах мира.

Особенности подключения проходных выключателей

Из-за принципа работы такие устройства часто называют переключателями. Вообще, на каждом корпусе обычно расположена схема. Здесь также указаны степень защищенности и обозначения зажимов. Буквой «C» обозначают общую линию, а «P» относят к перекидным контактам. Если их расположить неправильно, вся схема работать не будет. Но так как переключатели бывают разных видов, то и способы их подключения немного отличаются. В любом случае перед началом работ не стоит забывать о безопасности. Поэтому в первую очередь следует отключить электричество.

Устройство и принцип работы переключателей Legrand

У продукции французской компании Legrand отличное соотношение цены и качества. Ее товары надежные и учитывают самые современные технологические тенденции. Несмотря на это, устройства для управления осветительными приборами достаточно простые. Принцип их действия сводится к тому, чтобы замыкать и размыкать цепь. А состоят они из нескольких основных компонентов:

коммутирующий модуль с переключающим механизмом;

одна или несколько клавиш для управления переключающим механизмом.

Одноклавишные модели

Конструкция представляет собой выключатель с одним входом и двумя выходами. Этим они напоминают обычные двухклавишные модели. Использовать их для проходного действия не получится, так как принцип работы отличается. Один из выходов является общим, второй – перекидным. Два устройства соединяют между собой с помощью кабеля. Когда нажимают на клавишу первого устройства, цепь замыкается, и включается свет. Разомкнуть цепь помогает второй выключатель. В обратной последовательности они действуют точно так же.

Схема подключения одноклавишных моделей

К главным особенностям выключателей Legrand Etika можно отнести безвинтовые зажимы. Достаточно вставить кабель в специальный разъем, причем использовать можно как одножильные провода, так и многожильные с сечением от 1 до 2,5 квадрата. Чтобы было удобно работать с зажимами, следует зачистить провода примерно на 1 см. Для подключения потребуются два устройства. Чтобы было проще понять, как их соединить, посмотрите на схему:

К первому устройству подключают фазу. Затем соединяют его со вторым при помощи двух кабелей. К светильнику подключают провод со второго устройства и нулевой. Когда оба устройства находятся в состоянии 1, светильник включен. Если какое-то устройство находится в состоянии 2, свет не горит. Такой подход является самым легким и дешевым. Стоит отметить, что модели с сенсорным управлением или подсветкой подключаются почти так же. Единственным отличием здесь выступает отдельная цепь для питания.

Двухклавишные модели

В отличие от одноклавишных типов, здесь присутствуют 2 входа и 4 выхода. Чтобы их не перепутать, достаточно присмотреться к обозначениям. Они указаны стрелочками. Схема здесь немного сложнее, но все равно достаточно простая. Нужно лишь соблюдать элементарные правила монтажа электрики. Двухклавишные модели используют, чтобы управлять сразу несколькими светильниками или одним светильником, но с двумя лампами.

Схема подключения двухклавишных моделей

Как и в случае с одноклавишным выключателем, здесь не используются винтовые зажимы, да и принцип подключения такой же, просто больше входов и выходов. Более понятно можно это увидеть на схеме:

Из этой схемы видно, что фаза не проводится отдельно к каждому входу первого выключателя. Во-первых, в этом нет смысла. Во-вторых, так получается дороже. Достаточно установить перемычку. Если в светильнике 3 лампы, устанавливают трехклавишные переключатели по такому же принципу.

Несколько выключателей

Соединить пару переключателей, в том числе с двумя или тремя клавишами, не так уж сложно. Но иногда требуется управлять светом из нескольких мест. Например, можно использовать три, четыре или больше точек. Схема принципиально отличается от тех, которые были представлены выше. Здесь используют промежуточный перекрестный прибор. Например, для создания трех точек потребуется установить 2 проходных переключателя и 1 перекрестный. Он работает с двумя цепями. Когда одна отключается, прибор создает новую цепь. Схему можно представить следующим образом:

1 – первый проходной переключатель;

2 – второй проходной переключатель;

3 – перекрестный переключатель.

Когда требуется еще больше точек, устанавливают дополнительные перекрестники. В такой схеме очень много подключений, поэтому следить за правильным ходом работ особенно важно.

Как проверить подключение

Чтобы схема работала правильно, после подключения устройств следует их протестировать. И только потом можно заняться окончательным монтажом. Проверить работу достаточно легко. Нужно лишь повторить 5 простых шагов:

Включить первый переключатель.

Убедиться в том, что лампа загорелась.

Перейти ко второму переключателю и нажать на клавишу.

Убедиться в том, что лампа потухла.

Повторить действия в обратном порядке.

Если в каком-то положении переключатели работают неправильно, значит, при подключении была совершена ошибка. Может быть, перепутали местами контакты «P» и «C». Конечно, не стоит забывать подать напряжение в цепь.

В больших помещениях проходные переключатели значительно упрощают возможность использования осветительных приборов, да еще и помогают сэкономить. Именно поэтому их все чаще выбирают покупатели. Установить их не так уж сложно. Если вы только собираетесь покупать проходной переключатель, посмотрите каталог компании Vivaset. У нас широкий ассортимент продукции и доступные цены.

• The command can be selected independently from lines status. If in presence of auxiliary voltage necessary to electric command, it can be done only if it respects the chosen functional logic. The ATS continuously checks, in fact, that the provided command is in compliance to breakers status (Q1 – Q2 – QC) and to functioning logic table chosen for the plant. If the command is not coherent, it will be discarted.

• The command of changeover devices, in Legrand Default configuration, is continuos. The user can set the kind of command modifying the parameter P07.n.06 (using the layout with three devices, it is recommended to use the continuos command).

In the Standard configuration, (device with 2 sources (U-U) and 1 tie breaker), logic control is done respecting the following table:

The selected device is highlighted using a blinking square frame around it.

After the device has been selected, the command can be done using the related keys “OPEN” and “CLOSE” in the “command area” (the command will be received if the button is pushed for at least 0.5s).

The command is given only to the selected device. If the command isn’t in agreement with the logic control, it will be discarted and the square frame blinks until the command is coherent.

In the setup U-G , Pressing MAN key the generator starting command is automatically given (the relative output must be necessary enabled). For example, if line 2 is set for U-G mode (U-G setup with tie breaker QC ), the starting command of generator is possible just when the device Q2 is selected.

To remove the starting generator command, it is necessary to select the device related to generator line and press MAN.

The cooling time counter starts, after few time the command is removed and the generator stops.

In case the ATS is set in “closed transition” mode, the command of devices occurs like for “open transition” mode.

Automatic mode (AUT)

• In automatic mode, the ATS checks permanently the lines and breakers status. Starting from the status of lines S.Q1 and

S.Q2, it performs autonomously the closing/opening operations of breakers Q1, Q2 and, in function of command logic chosen, it manages the command of tie breaker QC and the optional startup/shutdown of the generator set.

• When the main line (S.Q1) exceeds the specified limits for a time higher than the one set, the green LED (line presence) switches off giving a “threshold out” alarm. The ATS disconnects the load from S.Q1 and connects it to the S.Q2 (if it is available and within admitted limits) closing also the QC. After S.Q1 returns within the specified thresholds, the ATS moves the load on this one after it has checked the stability and the quality of line and it opens the QC.

• During the transfer operations with tie breaker QC, the device Q2 stays closed assuring the service continuity of load.

• The automatic functioning cycles are different in relation of kind of logic applied.

The programmables logics control are the following:

• Control of 2 lines and 1 tie breaker (2 lines and three devices — Default)

2S — 1T SI Standard Legrand

2S — 1T-PL

2S — 1T-PL

2S — 1T –AI

2S — NPL

• Control of 2 lines and 2 devices in “open transition” mode

• Control of 2 lines and 2 devices in “closed transition” mode

For each logic it is possible to choose the kind of lines control selectioning the mode U-U, U-G, G-G, establishing if the command is related to motor breakers or contactors and defining the line priority.

3.3.1 Control of 2 lines and 1 tie breaker QC (2 lines and 3 devices) — Standard

The ATS in standard configuration is able to control 2 lines U-U (Utility — Utility) and 1 tie breaker. This kind of control can be modified in case of necessity to associate a generator.

It is possible to select different kinds of control in function of plant requirements.

It is possible to bring some changes passing from a control U-U to U-G or G-G. To do this is enough to modify the parameter of line to control, to activate the extended programmables outputs with external modules to control generator.

In the followings tables are shown the different logics:

3.3.2 Logic type C: 2S – 1T – SI Standard Legrand (Default)

With this logic it is possible the control of 2 sources S.Q1 and S.Q2 supplied from transformers or generics lines. The sources characteristics have to allow the contemporary power supply of Load 1 and Load 2. Using this logic, it is possible to supply loads from a single source closing a line breaker Q1 or Q2 and the tie breaker QC.

3.3.6 Control of 2 lines and 2 changeover devices

The ATS can control 2 power sources S.Q1 and S.Q2 and control the changeover of them using devices Q1 and Q2.

In this configuration the ATS can manage the changeover in “open transition” or “closed transition” modes.

These different modes of control require different setup of changeover system.

3. Operating mode

3.3.7 “Open transition” changeover:

The logic of control and changeover in mode “open transition” respects the general rules of switch between two lines. This command logic provides to open the device of not commanded line and after the closing of commanded line. The same logic of command is applied when the priority line comes back.

It is possible to apply this logic to systems U-U, U-G and G-G.

The advantage of this kind of management is to have possibility to mechanically interlock breakers and to avoid the temporary closing (also manually of both lines on the load).

3.3.8 “Closed transition” changeover

N.B. The “closed transition” (see parameter P.08.14 of menu M08 “switch”) control logic can be used only with ATS in AUT mode (automatic control of sources and devices). If the ATS is switched in MAN mode (electric command of breakers from ATS), it works following the “open transition” logic. The same behaviour is present passing from

AUT to OFF/RESET mode.

The logic of command and control of two lines for the changeover in “closed transition” is used to reduce to minimum the interruptions of energy. This logic allows to avoid the second interruption of energy during the changeover between secondary line (generator) to primary line (grid). Generally it is applied in changeover system type (U-G). In case of blackout of primary line, the relative breaker is opened and the starting command of generator on secondary line is given. After the secondary line (generator) is available, the breaker Q2 will be closed and the load is supplied from S.Q2.

When the primary line is available again, the ATS waits that all parameters of voltage, frequency and phases synchronism are correct and it commands the closing of Q1. The breaker Q2 will remain anyway close for a configurable time. After, the changeover is completed opening Q2. For a short period, the load is supplied from net and generator in parallel.

For this application it is MANDATORY to have specific generators capable to self regulate in order to guarantee that 2 lines are in perfect synchronism.

N.B. For this application, the mechanical interlock HAVE NOT TO BE INSTALLED to permit the contemporary closing of the lines.

4. Power-up

• The ATS can be supplied at 100-240VAC o 12-24-48VDC. In case of simultaneous presence of both power supplies, priority is given to the AC power supply.

• After first power-up the device normally starts in OFF/RESET mode.

• During the normal work of ATS, if it switches off, when it will be switched on it comes to operating mode actives before the switching off.

If it is necessary to modify this behaviour, the parameter P01.03 in the M01 “utilities” menu has to be changed.

• The automatic transfer switch can be supplied with a second Vaux with the input “DC battery” from 12VDC to 48VDC.

The same input could be used for the battery control, if it is activated. In this case it is necessary to set the correct battery voltage in the menu M04 “battery”.

• During power-up all the LEDs blink in order to verify their operation.

5. Main menu

• The “main menu” is made up of a group of graphic icons that allow to access to functions. In function of selected icon, a description will appear on the display.

Fig. 14 — Main menu

• The main menu allows the quick access to measurements and settings.

• Starting from main page, press ✓ OK. The menu screen is displayed.

• Press or to rotate clockwise/counter clockwise to select the required function. The selected icon is highlighted and the central part of the display shows the description of the function.

• Press (AUT) ✓ OK to activate the selected function.

6. Password access

• The ATS has a password function that at first switching on is not active in order to access to all parameters (Password

OFF).

N.B. In case of password activation/modify, it is recommended to make a copy of it to guarantee future access with desired rights.

• It is possible to define different level of password in order to permit different access to “settings/commands” menu in function of access rights.

• If password is activated, in order to enter to protected data, it is necessary to insert the correct code.

• To enable password management and to define numeric codes, see M03 “password” menu.

• There are different access levels:

• Password disabled (OFF)– The password is disabled. Complete access to all parameters (Legrand Default).

• Password enabled (ON) – The password is enabled:

— Access without to insert password (Lev.1)— The password is enabled but not inserted. This access allow the visualization only.

— User Level access (Lev.2)— It allows the change of mode, the clearing of recorded values and editing of a limited number of setup parameters.

— Advanced Level access (Lev.3) — Complete access to all parameters.

8. Expandability

• The automatic transfer switch can be expanded with additional modules.

It is possible to connect a maximum of 3 expansion modules at the same time.

Fig. 32 — Expansion modules

• The expansion modules provide additional resources in order to extend the checking and managing chances. These ones can be parameterized and managed through the dedicated setup menus.

• The supported expansions modules can be grouped in the following categories:

— I/O modules

• Procedure to add an expansion module:

— remove the power supply to automatic transfer switch (230VAC and auxiliary in DC, if present);

— remove the protecting cover of one of the expansion slots;

— insert the upper hook of the module into the fixing hole on the left of the expansion slot;

— rotate right the module body, inserting the connector on the bus;

— push until the bottom clip snaps into its housing.

• Unless otherwise indicated, the insertion order of the modules is free.

• Fit the specific module lock accessory included in the package to improve expansion module fixing safety in applications subjected to strong vibrations.

• To fit this accessory:

— remove the two right screws with a Torx T7 screwdriver

— Set the jumper over the previously coupled modules

— fasten the screws back in their original seat.

• Once expansion modules are installed, the ATS recognize them when it will be powered on. It automatically recognises the kind of mounted expansions modules showing it on display.

• At switching on, if the device configuration has changed compared to the last saved, (one module has been added or removed), the ATS asks the user to confirm the new configuration. In case of confirmation, the new configuration will be saved and will become effective, otherwise the mismatch will be shown at every subsequent power-on of the system.

Figura 33 — Configuration change

N.B. One time the module has been installed, the associated functions have to be set by the user.

8. Expandability

• The I/O numbering is shown under each module.

• The I/O status (active/not active) is graphically shown in the following way:

— ACTIVE: with words in negative (white on black background)

— NOT ACTIVE: with words in positive (black on white background)

Fig. 34- I/O Active/Not active

• The setup menus related to the modules are always accessible, even if the expansion modules are not physically fitted.

• It is possible to add modules I/O of the same type; the setup menus are multiple and identified by a sequential number.

• The following table shows how many modules of each group can be mounted at the same time.

9. Communication

• Into menu “communication” M10 it is possible set COM channel

• The ATS has an integrated communication port RS-485 (COM1).

• The inputs and outputs are identified by a code and a sequence number. Example: the digital inputs are identified by code INPx, where x is the number of the input. In the same way, digital outputs are identified by code OUTx.

The numeration of input/output is based on mounting position of expansion modules, with progressive numeration from top to bottom.

• The expansion I/O numbering starts from the last I/O fitted on the base unit. For example, for digital inputs , INP1…

INP12 on the basic unit and thus the first digital input on the expansion modules will be named INP13. The I/O numbering is shown in the following table:

• Inputs/outputs can be associated to internal variables (bit) that can be associated between them.

Example: limit thresholds can be applied to detected measures or eventual counter related to an activation or fan input x.

• The following table shows all the internal variables managed by the ATS with their range (number of variables per type).

Functions associated to the inputs are the 6 described in the above table.

• LIMx: internal variable that identifies a limit value set by the user and managed by the ATS. Its status (active or not) depends by out-of-limits of one measurement set by the user.

• CNTx: internal counters that can count pulses coming from an external source (through a digital input INPx) or the times that a certain condition has been verified.

Example: defining a limit threshold LIMx as count source, it will be possible to count how many times one measurement has exceeded a certain limit.

• REMx: it allows the managing of remote variables.

• UAx: it allows the activation and managing of 4 programmable alarms.

• PLCx: management of variables of PLC logic (see dedicated programming manual).

• TIMx: management of timer

9.1

Limit thresholds (LIMx)

• The LIMx thresholds are internal variables whose status depends by out-of-limits of one measurement set by the user.

(example: phase to phase voltage L1-L2 higher than 400V).

• The setting of thresholds value is calculated starting from a base value.

Example: “400 V” adding a multiplicative factor “x 1” 400 x 1 = 400V).

• For each LIM, there are two thresholds: upper and lower.

N.B. The upper threshold must always be set to a value higher than the nominal one and the lower threshold must always to be set to a value lower than the nominal one.

• The control mode of thresholds can be done in 3 modes:

— MIN function: when the value of selected measure is under lower limit, after the delay set, the threshold will be activated. When the value of selected measure is over the upper limit, after delay set, the threshold will be restored.

— MAX function: when the value of selected measure is higher than the superior limit, after the delay set, the threshold will be activated. When the value of selected measure is under lower limit, after delay set, the threshold will be restored.

— MAX+MIN function: when the value of selected measure is under lower limit or over the upper limit, after the delays set, the threshold will be activated. When the value of selected measure comes back into the limits, the threshold will be restored (if not retenitive).

• The managing of limit can be done in 2 modes: with memory or without memory. In the first case the reset of the alarm can be done only manually (retenitive); in the second case the reset of alarm is automatic, if the value comes back into the limits. The setting can be done using the dedicated command in the “commands” menu.

See setup menu M15 “Limit thresholds”.

9.2

Remote-controlled variables (REMx)

• The automatic transfer switch, with an external supervision software, can activate outputs (OUTx) via Modbus protocol

RS 485 channel. This can be done with remote variables REMx.

9.3

User Alarms (UAx)

• User can set a maximum of 8 programmable alarms (UA1…UA8).

• Conditions that generates the alarm can be different:

— In association of one thresholds LIMX set.

— Activation of digital inputs INPx.

— The same criterion can be used to combine an alarm to complex conditions resulting from the logical Boolean combination of inputs and thresholds, etc. The PLCx variables will be used in this case.

• For each alarm, the user can define a message that will appear on the alarm page.

• Properties of alarms can be defined by the user in the same way that normal alarms.

• When several alarms are activated at the same time, they are displayed sequentially, and their total number is shown on the status bar.

• To reset one alarm that has been programmed with latch, use the dedicated command in the “commands” menu.

• For details on alarm programming and definition, refer to setup menu M21 “User alarms”.

9.4

Counters (CNTx)

• This function allows, by selecting a control channel, to activate a counter (see chapter M16 “counters”).

• It is possible to count:

— Impulses acquired from inputs INPx;

— The numbers of activations of outputs OUTx;

— The overcome of limits LIMx;

— Activation of known variables.

• The description of counters CNTx can be customized with a test of maximum 16 characters.

• The unit of measure of counters Umn can be customized with a test of maximum 6 characters.

9.5

PLC Logic (PLCx)

• ACU Software can be set using a ladder program for creating a PLC internal logic inside the ATS, so as to be able to freely manage any function necessary for generator accessory applications.

• In the program logic, all the variables managed internally by the ATS can be entered, such as inputs (INPx), threshold limits (LIMx), remote variables (REMx), controller states (RALx) etc.

• The processing results of the various branches of the ladder logic are stored in internal variables (PLCx), which may later be used to control the ATS outputs, or as support memories to built a more complex logic or to control the alarms defined by the user (UAx).

• It is additionally possible to create timers inside the PLC program using the programmable timers of the M17 menu.

• The operation of the logic created with the ladder program may be checked in real time and possible corrected on the specific ACU software window.

9.6

Timers (TIMx)

• The system includes 8 timer variables, named TIM1..TIM8.

• These variables may be used either in the PLC ladder logic or in combination with the OUTx outputs or in combination with UAx user alarms.

• Each timer variable has an input which controls it (e.g. a LIMx limit or an INPx inputs etc.). The state of this variable changes from FALSE to TRUE (ramp up) and the timing variable also changes from FALSE to true but only remains true for the specified time and then returns FALSE.

• Whenever the input variable becomes false, the TIMx variable also becomes FALSE (this also occurs before the end of the programmed time) and the time counter is reset to zero.

10. Keypad lock

• The automatic transfer switch keypad can be locked, avoiding not desidered command.

• Once the keypad is locked, it will only be possible to view measures, but not to change operating mode or to operate in MAN mode on devices. If the icon menu is shown and the keypad is locked, wait 2 minutes to return to main page.

• The activation of keypad lock can be made in the followings ways:

— With a programmable input (activate the function “keypad lock”);

— With frontal keys;

— With SW ACU.

• To lock or unlock the keypad, press key and, while holding it down, press key three times without releasing it at the end.

Release then key and then press it 5 times, then release both keys.

• When the keypad is locked, the display shows the sentence “KEYBOARD LOCKED”. If the keypad isn’t locked the display shows the sentence “KEYBOARD UNLOCKED”.

• The managing of setting parameters can be done also using the PC Software “ACU configurator” (available to free download on Legrand E-catalogue.

• Using software ACU it is possible to transfer set-up parameters from ATS to PC, generating a file. It is also possible to transfer to ATS a file with parameters from SW ACU.

• It is possible to transfer parameters in 2 ways:

— Total transfer: all parameters are uploaded on ATS in one time

— Partial transfer: only menu with modified data will be uploaded to the ATS

• The PC can be used also to define “information page” where to add informations, charachteristics, data etc…concerning the application.

11.4

IR port

• The parameters of the automatic transfer switch can be configured and consulted also through the front optical port, using a USB or WiFi dongle.

• Using this port it is possible to configure and to dialogue with the automatic transfer switch without the need to access to the rear of the device or having to open the electrical panel. This connection is isolated from internal circuit ensuring safety for the operator.

• This port guarantees IP65 front protection.

• Simply holding the USB/WiFi dongle up to the front panel, connecting the plugs to the connectors the device will be connected. The recognition between devices will be shown by the green “LINK” LED on the programming dongle.

12. Generator test

• The ATS allows to the user to program a periodical control of generator start.

• The automatic test is a periodic test carried out at specific intervals (interval managed on from “setup” menu). This test can be done only if the ATS is in AUT mode and the function has been enabled.

• It is possible to decide in which days of the week the automatic test can be executed and at what time of the day (hours; minutes). See menu M11 “automatic test”.

• If there are multiple generators in the system, only one is started for each automatic test. The others will be started in sequence the next time.

• After starting, the generator works for a programmable time after which it stops. The message “T.AUT” appears on the display before starting.

• The test can be enabled or disabled for each single generator using the parameters of menu M11 and on the Automatic

Test display page without needing to open the setup menu.

— On the Automatic Test page, press and at the same time.

— Select the required generator by pressing and . Enable the test with and disable it with .

— OK Save and exit the setting.

— The test can be stopped by pressing key OFF — RESET.

12.1

Generator command with simulation of line missing.

• It is possible to simulate the lack of the priority line by SW in order to verify the behavior of the transfer switch system.

• The simulation can be started either using the “commands” menu (command C.24) or via a digital input, for example connecting it to a key switch, programming the function of the input to the execution of the command C.24.

• The simulation consists in considering the priority line absent for 3 minutes (even if it is actually present). During this time the main page shows the message “SIMUL xxx” with the countdown of the time.

• The simulation will cause the start of the generator (if present) and a load transfer exactly as in the automatic cycle.

• It is possible to stop the simulation at any time by passing in OFF mode.

N.B. Doing the simulation through commands menu, user must start from the OFF mode (which allows access to the menu). Once selected and confirmed the C.24 command, exit the command menu. The unit will independently switch to

TEST mode and it starts the simulation.

13. Parameters

• In menu “parameters” are described all parameters, their changes and it is defined the work mode of ATS. Menu is composed by 22 parts: from M01 to M22.

• Each menu is composed by specific parameters Px that can be modified in function of needs.

For example, the definition of control characteristics of power sources can be definied by the customer using parameters of M08 “load changeover” menu and M09 “source line control ” menu.

• With menu M09 it is possible to set nominal data for power sources such as nominal voltage, nominal frequency that could be used to set thresholds.

• The ATS can be set to do voltage checks in three-phases lines with or without neutral, bi-phases or single-phase

(P02.07).

• In case of lines three-phases or bi-phases it is possible to choose if monitor/control phase-phase voltage or phase-neutral voltage or both. (P02.08).

N.B. Nominal voltage set with P02.02 must be referred to phase-phase voltage.

It is possible set a transformation ratio TV associated to the control inputs establishing criteria in M02 “general” menu. In case a lower voltage is applied but proportional to that of plant, limits of measures will be real values of plant.

• P07.n.01 — Alphanumeric description which identifies the line breaker on the display synoptic panel.

• P07.n.02 — Interlock time from the opening instant of the breaker Qn to the closing of another breaker.

• P07.n.03 — Timeout between sending of a control from a line breaker and the actual execution of the operation. After having sent an opening or closing control to the breaker, alarms A03 or A04 are generated if it is not positioned correctly before the timeout. It works when the auxiliary state contacts of the breakers is programmed and wired.

• P07.n.04 — Minimum opening control time, when the breaker control is defined by means of a pulse (P08.01 = Pulse breaker). For applications with motorized line breakers, this must be set to a sufficient time to allow complete charging of the springs. This time is considered also when working in continuous control mode.

• P07.n.05 — Closing control pulse time.

• P07.n.06 – Otherwise, the breaker control is selected as continuous (P08.01 = Continuous breaker), defines the behaviour of the board when it switches to the OFF operating mode. OFF = The control relays are de-energised. NOC = The control relays remain in in their original state (No Change).

• P07.n.07 — In case of timeout caused by the line breaker Qn failing to close (open feedback contact) causes the transfer of the load on an alternative line.

• P07.n.08 — Minimum coil deactivation pulse duration for breaker opening pulse.

• P07.n.09 — Time elapsed between minimum voltage opening pulse and breaker spring loading control.

• P07.n.10 — This defines whether in case of failure to close the ATS must perform a retry consisting of a cycle of opening/spring recharging cycles followed by a new closing attempt. The failed closing alarm will be generated if the second attempt also fails. OFF = Closing is not retryed. AUT = Retry is manual only. AUT+MAN = Retry enabled in both modes. CLOSING = Closing retry is executed in AUT or MAN only in case of failed closing but not when breaker opens unexpectedly.

• P07.n.11, P07.n.12— Conditional enable of breaker. OFF = Breaker is enabled normally. Any other setting = The breaker is enabled only if the selected variable is active. When the variable is not active, if the tie breaker is open, its closing will be avoided. If the breaker is closed, it will be opened.

• P08.01 – This defines the transfer device type for power lines valid for all breakers Qn defined in menu M07.

Pulse breaker = Motorised breakers with pulse control. Continuous breaker = motorised breakers with continuous control. Contactor = Contactor coil control.

• P08.02 — This defines the transfer strategy. OBP = (Open Before Presence) this means that in automatic mode the opening control of a switch is generated when the line is beyond the limits regardless of the alternative line state.

OAP = (Open After Presence) this means that in automatic mode the opening control of breaker is only sent after an alternative line is present in the limits.

• P08.03 — If in automatic mode all the sources are simultaneously non available (feedback with OC contact) for longer

Automatic transfer switch

than this time alarm A09 load timeout not powered appears.

• P08.04 — If this parameter is enabled after a transfer to an alternative line the return on the priority line does not occur automatically when it is re-established but must be controlled in manual mode.

OFF = Automatic return ON = Return to manual.

• P08.05 — Motor start-up delay when the priority line is not within the set limits. If it is set to OFF, the starting cycle starts at the same time as the opening of the priority line breaker.

• P08.06 – P08.07 – P08.08 — These parameters allow a timed rotation in the application with multiple generator exchanging the priority between the generators. P08.06 defines the rotation interval between the generator. The day of the day at which the rotation will occur is defined by P08.07 and P08.08.

If the rotation range is higher than 24h, then the rotation always occurs at the indicated time every n days. If it is lower than 24h, then it occurs at the indicated time and in the sub-multiples. For example, if the time is set to 12:30 with the rotation every 6h, there will be a rotation at 12:30, one at 18:30, one at 0:30 etc.

• P08.09 – This defines the time which separates the starting for one unit from the following one. If this time elapses after sending a start control without having detected the presence of voltage, alarm A2n Line n generator not available is generated and the system starts a second generator, where available.

• P08.10 – Normal = This parameter is set in normal modality for default. In this modality the ATS manages in automatic lines in function of quality and stability criteria set in menu “parameters”.

EJP (Effacement Jours Pointe) = in this modality, the ATS manage the lines in function of external signals that command the load transfer from the grid to the generator. This request is managed in two times using 2 programmable inputs set with the functions “Remote starting off load” and “Remote changeover” for EJP.

When the starting of generator is requested by means of closing of contact “remote changeover”, the starting generator delay starts (P08.11). At the end the generator starts. After, when changeover command arrives, the ATS checks the status of generator and the load is transferred.

Load will be supplied by the generator until the changeover command input persists. When this command lapses, the

ATS prepares to transfer the load on the main line starting the cooling cycle of generator. The EJP function is only enabled if the system is in automatic mode. The cutouts and alarms function as usual.

EJP-T = The EJP/T function is a simplified variation of the previous EJP, and in this case the engine start is controlled in the same way, but a timer switches the load instead of an external signal. This function therefore uses only one digital input, the starting input. The switching delay starts from when the programmable input INPx associated to the starting command closes (parameter P08.12).

SCR = The SCR function is very similar to the EJP function. In this mode, the starting input enables generator starting as for EJP, without waiting for start delay P08.11. The remote changeover input still has a switching go-ahead function after “Changeover delay” P08.12.

• P08.11 – Delay between the EJP start signal and the effective start signal sent to the generator.

• P08.12 – Delay for switching the load from S.Q1 to S.Q2 in EJP and SCR mode.

• P08.13 – If ON, in EJP , EJP-T and SCR mode, the load will not be switched back to the priority line in the case of a generator failure, but only when the signals on the EJP inputs give a go-ahead.

• P08.14 – Enabling to “close transition”.It allow how the changeover of load will be manage between two power sources all present (see chapter 3.3.7 — 3.3.8).

OFF = the load will be switched with “open transition” (Default).

ON = two power sources will be synchronized (if it is possible) or a spontaneous synchronization will be waited until a specific time.

The syncrhronization thresholds are defined from parameters P08.15 — P08.16 — P08.17 — P08.18. In presence of all synchronizations conditions, the load will be switched with “close transition” and temporary parallel. Obviously, the breakers and external protections must be appropriately configured in this case.

IN-PHASE = In this case, the synchronisation conditions will be sought but transfer will occur in all cases with the transition open. In this case, the load is passed to a new source the amplitude and phase of which is synchronised with the previous one

• P08.15 – Maximum voltage difference between the two sources to be synchronised expressed as a percentage of the rated voltage.

• P08.16 — Maximum frequency difference between the two sources to be synchronised.

• P08.17 — Maximum phase angle difference between the two sources to be synchronised.

• P08.18 — Minimum simultaneous dwell time between the three previous conditions before the synchronism is considered reliable.

• P08.19 — Maximum waiting time for the synchronisation conditions. After this time, an open transition is performed.

• P08.20 — Instantaneous parallel time in closed transition.

• P08.21 — P08.22 — These define the ON and OFF time of the pulse controls for increasing or decreasing the voltage or frequency, respectively. These times influence the programmed outputs with the increase voltage, decrease voltage, increase frequency and decrease frequency functions. The signals are intended to be sent to a generator control unit with the purpose of reaching synchronisation conditions.

• In the case of one or more alarms, the behaviour of the automatic transfer switch depends on the properties settings of the active alarms.

13.22

Alarm properties

The ATS has the possibility to manage and generate different types of user alarms (User Alarms, Uax) and for each one can be associated different properties:

• Alarm enabled – General enabling of the alarm. If the alarm isn’t enabled, it’s like if it doesn’t exist.

• Only AUT – The alarm can be generated only when automatic transfer switch is in AUT operating mode.

• Retained alarm – It remains in the memory even if the cause of the alarm has been eliminated.

• Global alarm – It activates the output assigned to this function.

• Q1 Locked– When the alarm is active, no commands are sent to Q1.

• Q2 Locked – Like previous property, referred to Q2.

• Siren – It activates the output assigned to this function, as configured in the alarm table.

• Inhibition – The alarm can be temporarily disabled by activating an input that can be programmed with the Inhibit alarms function.

• No LCD – The alarm is normally managed, but not shown on the display. This property is associated only if the alarm is not retenitive.

ALARM EXPLANATION

Battery voltage beyond the lowest threshold for a time exceeding the time set.

Battery voltage beyond the highest threshold for a time exceeding the time set.

The Q1 changeover device did not perform the opening or closing operation within the max. time set. After alarm A03 generation, the opening or closing command is inhibited.

Alarms are generated only if at least one of the two power sources S.Q1 or S.Q2 are present.

The Q2 changeover device did not perform the opening or closing operation within the max. time set. After alarm A04 generation, the opening or closing command is inhibited.

Alarms are generated only if at least one of the two power sources S.Q1 or S.Q2 are present.

The phase sequence recorded on S.Q1 (line 1) does not correspond to the one programmed.

The phase sequence recorded on S.Q2 (line 2) does not correspond to the one programmed.

The load has been without power for a time longer than the maximum specified with P05.11, either because both source lines (S.Q1 and S.Q2) were absent or because both Q1 and Q2 remained open.

Alarm generated by the input programmed with the Local battery charger alarm function connected to an external battery charger when at least one of the sources is in the limits.

Alarm generated by the input programmed with the generator

1 battery charger alarm function connected to an external battery charger when at least one of the sources is in the limits.

Alarm generated by the input programmed with the generator

2 battery charger alarm function connected to an external battery charger when at least one of the sources is in the limits.

Alarm generated by the opening of the external input with

Emergency function. Both Q1 and Q2 will be opened.

Q1 (Line 1) has tripped because of a plant protection (contact

CTR), signalled by activation of the input with function “Q1 breaker trip”.

Q2 (Line 2) has tripped because of a plant protection (contact

CTR), signalled by activation of the input with function “Q2 breaker trip”.

Q1 is not available because the input with function “Q1 breaker withdrawn” indicate that the breaker is not inserted into the base.

Q2 is not available because the input with function “Q2 breaker withdrawn” indicate that the breaker is not inserted into the base.

Alarm generated by the input Generator S.Q1 (Line 1) ready.

Alarm generated by the input Generator S.Q2 (Line 2) ready.

Alarm generated when the maintenance hours for S.Q1 arrive to zero. See M12 menu. Use the command menu to restore the working hours and to reset the alarm.

ALARM EXPLANATION

Alarm generated when the maintenance hours for S.Q2 arrive to zero. See M12 menu. Use the command menu to restore the working hours and to reset the alarm.

Alarm generated when the number of operations for S.Q1 reach the value sated in the menu M12. Use the menu commands to restore the function and to reset the alarm.

Alarm generated when the number of operations for S.Q2 reach the value sated in the menu M12. Use the menu commands to restore the function and to reset the alarm.

The device that manages the draw of auxiliary power supply from one of the available lines (DPS-auxiliary contact) signals a failure or improper operation.

QC did not perform the opening or closing operation before the timeout. The opening or closing control is inhibited after the alarm has been generated. The alarms are only generated if one of the power sources is present, i.e. higher than the minimum programmed thresholds.

QC has tripped because of a plant protection (contact CTR), signalled by activation of the input with function “QC breaker trip”.

QC is not available because the input with function “QC breaker withdrawn” indicate that the breaker is not inserted into the base.

The user alarm is generated by enabling the variable or associated input in menu M15.

14.1

Programmable inputs function table

The configuration installed on ATS by Legrand ensures the correct work if standard wiring diagrams supplied are respected.

WARNING: the modify of parameters could generate incompatibility with supplied wiring diagrams. It is recommended to not modify the original configuration.

Using expansion modules is possible to increase the amount of inputs available in order to do additional checks and controls (this solution is recommended to avoid the change of work mode of inputs in case of specific applications).

• The following table shows all the functions that can be attributed to the INPn programmables digital inputs.

• Each input can be set for an reverse function (NA – NC), delayed energizing or de-energizing at independently set times.

• Some functions require another numeric parameter, defined in the index (x) specified by parameter P12.n.02.

• See menu M12 “Programmable inputs” for more details.

The contact generates the breaker Q1 withdrawn alarm when the contact is open.

The contact generates the breaker Q2 withdrawn alarm when the contact is open.

When closed, it causes changeover to secondary line even if main line voltage is within limits.

It could be used to change priority between S.Q1 and S.Q2. The secondary line circuit breaker remains activated until this line remains within limits. It can be used for EJP function.

In AUT mode, when closed, it inhibits the return to main line after it has reverted to the limit range.

It is used to prevent the second power cut out due to re-transfer from occurring automatically at an unforeseeable time.

Inhib. Return open tra.

In AUT mode, when closed, it prevents automatic return to the priority line in open transition after it returns into the limits (it prevents opening of the line in use in the following conditions: input closed and so line in limits).

This prevents the second energy interruption caused by retransfer occurring automatically in an unpredictable moment in open transition.

Rem. Start off load

In AUT mode, when closed, it causes the starting of the priority generator after the time set with Pxx.xx. May also be used for the EJP function.
