Рис. 1
With the controller OFF, insert the key PSOPZKEY00 in the connector KEY/SPV. Connect and disconnect the serial and programming key
options with the 12-pin connector (relay) removed.
Note: the configuration jumper must be inserted in position A (technical leaflet MCH200485*)
Supervisor option
Connect the serial option (code MCH200485*) to the connector KEY/SPV.
Warnings
• If using a single power transformer for the μC2SE and the accessories, connect all the G0 terminals on the various controllers or boards to the same terminal on the secondary, and all the G terminals to the other terminal on the secondary, to avoid damaging the instrument;
• For use in residential environments, a shielded cable (conductor + shield) is required for the tLAN connections (EN 55014-1);
• Avoid short-circuits between V+ and GND so as to not damage the instrument:
• Separate the power cables (relay outputs) from the probe, digital input and serial cables;
• Use the power transformer exclusively dedicated to the electronic controllers.
Protection against electric shock and warnings for maintenance
Disconnect the power supply before working on the board during the assembly, maintenance and replacement operations.
The system made up of the control board (MCH200*03*) and the other optional cards (MCH200002*, MCH200485*, MCHRTF****,
CONVONOFF*, CONV0/10A*, EVD000040*) represents a control device to be incorporated in class I or class II equipment. The class of
protection against electric shock depends on how the control device is integrated into the unit made by the manufacturer.
The protection against short-circuits, due to defective wiring, must be guaranteed by the manufacturer of the equipment that the control
device is built into.

Настройка через параметре “/4”
Опциональный программатор
Выключив контроллер, подсоедините программатор PSOPZKEY00 к разъему KEY/SPV. Перед
подсоединением и отсоединением программатора или адаптера последовательного интерфейса
проверьте, что 12-контактный разъем (реле) отсоединен.
Прим.: перемычка должна стоять в положении A (см. техническое описание для MCH200485*)
Опциональная диспетчеризация
Подсоедините адаптер последовательного интерфейса (код MCH200485*) к разъему KEY/SPV.
Внимание
• При питании контроллера μC2SE и аксессуаров от одного силового трансформатора, все клеммы
GO разных контроллеров или плат подсоединяются к одной клемме вторичной обмотки, а все клеммы
G подсоединяются к клемме вторичной во избежание повреждений оборудования;
• При использовании в жилых помещениях применяется экранированный (проводник + экран)
соединительный кабель tLAN (EN 55014-1);
• Берегитесь короткого замыкания между клеммами V+ и GND во избежание порчи оборудования:
• Кабели питания (релейные выходы) прокладываются отдельно от кабелей датчиков, цифровых
входов и последовательного интерфейса;
• Используемый силовой трансформатор должен быть предназначен для электронных
контроллеров.
Защита от поражения электрическим током, указания по обслуживанию
Перед сборкой, обслуживанием или заменой платы отсоедините электрическое питание.
Если в состав системы входит плата управления (MCH200*03*) и другие опциональные платы
(MCH200002*, MCH200485*, MCHRTF****, CONVONOFF*, CONV0/10A*, EVD000040*), она
представляет собой устройство класса I или II. Класс защиты от поражения электрическим током
зависит от правильности интеграции устройства управления в контроллер производителем.
Защита от короткого замыкания из-за неисправной проводки обеспечивается изготовителем
оборудования, куда интегрируется устройство управления.

  When stopping, the valve is managed fi rst and then the actual compressor as a whole. Both FIFO logic and timed operation will involve either one circuit or the other. The activation and deactivation of the valves are not subject to timers, but rather only a hysteresis that is equal to the set point and the differential of the step (in fact the valve performs the same function as a hermetic compressor).
