4.2.2 Pumping

(e.g. after overflowing from supply 

1

)

1

Press the green button 

= switch on the transfer

pump.

2

The green indicator light comes on.

The pump is protected against overheating (excessive
ambient temperature or insufficient supply pressure over
a long period). At a cylinder head temperature above
90°C the pump is switched off automatically and an indi
cator light in the red button (Stop) comes on.

In the event of leaks or other malfunctions, immediately
press the Emergency Stop button.

If necessary remove the power plug.

When the desired pressure has been attained:

3

Press the red button = switch off the transfer pump. At
a filling end pressure of 220 bar, the transfer pump is
automatically switched off.

4

When filling is complete, close the 200 bar filler valve.

OPERATION

4.2.2 Перекачивание

(например, после перепуска из накопительного балло
на 

1

)

1

Нажмите зеленую кнопку 

= включить перекачи

вающий насос.

2

Включается зеленая индикаторная лампа.

Насос защищен от перегрева (вследствие чрезмерной
температуры окружающей среды или недостаточного
питающего давления в течение длительного периода
времени). При температуре головки цилиндра выше
90 °C насос автоматически выключается и загорается
красная кнопка (Останов).

При возникновении утечек или других неисправностей
немедленно нажмите кнопку аварийного останова.

При необходимости выньте вилку электропитания.

Когда будет достигнуто желательное давление:

3

Нажмите красную кнопку = выключите перекачи
вающий насос. При конечном давлении наполнения
220 бар перекачивающий насос автоматически вы
ключается.

4

Когда заправка завершена, закройте наполнитель
ный вентиль 200 бар.

4.2.3 Окончание процесса заправки

1

Закройте вентили на заправленных кислородных
баллонах.

2

Откройте предохранительный клапан  200 бар,  пока
не стравится давление – затем снова закройте.

3

Свинтите заправленные кислородные баллоны с на
полнительных соединителей и немедленно заглушите
наполнительные порты и вентили баллонов.

4

Закройте впускной вентиль

ЭКСПЛУАТАЦИЯ

4.2.3 Ending the filling process

1

Close the valves of the filled oxygen cylinders.

2

Open the 200 bar relief valve until the pressure is re
leased – then close again.

3

Unscrew the filled oxygen cylinders from the filler con
nection and immediately seal the filler ports and cylin
der valves.

4

Close supply valve 

V1

.

4.3 Combination of overflow and pumping

(Perform as specified below, if all supply cylinders are
first filled with 200 bar)

1

Overflow from supply 

1

2

Pump from supply 

until the filling end pressure is 220

bar.

4.3

Комбинация перепуска и перекачивания

(Выполняется, как указано ниже, если все баллоны для
хранения кислорода исходно заправлены до 200 бар)

1

Перепуск из накопительного баллона 

1

2

Перекачивание из накопительного баллона 

1

, пока

не будет достигнуто конечное давление наполне
ния  220 бар.

Если давление в накопительном баллоне 1 падает
ниже 110 бар:

1

Перепуск из накопительного баллона 

1

2

Перекачивание из накопительного баллона 

1

, пока не

будет достигнуто давление наполнения 110 бар.

3

Перепуск из накопительного баллона 

2

4

Перекачивание из накопительного баллона 

2

, пока

не будет достигнуто конечное давление наполне
ния  220 бар.

Если после операций заправки давление падает
до 55 бар в накопительном баллоне 1 и до 110 бар
в накопительном баллоне 2:

1

Перепуск из накопительного баллона 

1

2

Перепуск из накопительного баллона 

2

3

Перекачивание из накопительного баллона 

до

давления 220 бар.

If the pressure in supply 1 falls below 110 bar:

1

Overflow from supply 

1

2

Pump from the supply 

until the pressure reaches 110

bar.

3

Overflow from supply 

2

4

Pump from supply 

until the filling end pressure is 220

bar.

If the pressure falls to 55 bar in supply 1 and to 110
bar in supply 2 after further filling operations:

1

Overflow from supply 

1

2

Overflow from supply 

2

3

Pump from supply 

up to a pressure 220 bar.
