5.4.2 CM-SW-01
Standard for all CSW105 compressors
The compressor module integrates the entire electronic
periphery of the compressor: It allows monitoring the
essential operating parameters of the compressor: mo-
tor and discharge gas temperature, phase and rotation
direction monitoring, oil supply and application limits
and thus protects the compressor from operation under
critical conditions. For further information, see Tech-
nical Information ST-150.

NOTICE
The compressor module may be damaged or
fail!
Never apply any voltage to the terminals of CN7
to CN12 – not even for test purposes!
The voltage applied to the terminals of CN13
must not exceed 10 V!
The voltage applied to terminal 3 of CN14 must
not exceed 24 V! Do no apply voltage to the
other terminals!
The following components are completely installed and
wired in the state of delivery:
• Slider position indicator.
• Oil monitoring (OLC-D1).
• Solenoid valves for capacity control and V
i
.
• Discharge gas temperature sensor.
• Low pressure and high pressure transmitter.
Modification to these components or their wiring is not
required and should not be done without consulting
BITZER.
The following components are not installed and wired in
the state of delivery and need to be connected:
• Motor temperature monitoring (PTC sensor in motor
winding).
• Phase monitoring (in case of a phase failure or inad-
missibly high phase asymmetry).
The compressor module internally supplies voltage to
the peripheral devices (solenoid valves, oil monitoring
device and slider position indicator) and to the terminal
strips CN7 to CN12.
Please refer to the Technical Information ST-150 for in-
formation on all connections.
5.4.3 SE-i1
This protection device with extended monitoring func-
tions can be used as an option for all HS.53 .. HS.85
compressors and CSH and CSW compressors.

• Dimensions and integration in the control identical to
SE-E1.
• Suitable for all CS. compressors.
• Monitoring functions are basically identical to those
of SE-E1. However, the SE-E2 monitors phase fail-
ure during the entire running time of the compressor.
For further information, see Technical Information
ST-122.
5.4.5 Monitoring of the oil circuit
• For short circuits without liquid injection (LI) for addi-
tional cooling and for small system volume and small
refrigerant charge: Indirect monitoring with oil tem-
perature sensor (standard)
!
!
NOTICE
Lack of oil leads to a too high increase in tem-
perature.
Risk of damage to the compressor!
• For circuits with liquid injection (LI) for additional
cooling and / or for great system volume as well as
parallel compounding: Monitor oil level directly with
opto-electronic oil level monitoring (option), see
chapter Opto-electronic oil level monitoring OLC-D1-
S, page 26. The connection is on the compressor
housing, see chapter Connections and dimensional
drawings, page 14, position 8.

5.4.6 Dispositifs de sécurité pour la limitation de
pression (HP et LP)
• Nécessaires pour sécuriser le champ d’application
du compresseur de manière à éviter que des condi-
tions d’utilisation inadmissibles ne surviennent.
• Il ne faut en aucun cas les raccorder au raccord de
maintenance de la vanne d’arrêt !
• Régler les pressions d’enclenchement et de déclen-
chement conformément aux limites d’application et
les contrôler exactement au moyen d’un test.
5.4.7 Chauffage d’huile
Le chauffage d'huile garantit le pouvoir lubrifiant de
l'huile même après des temps d'arrêt prolongés. Il per-
met d'éviter un enrichissement de fluide frigorigène
dans l'huile et donc une réduction de la viscosité.
L'huile doit être chauffée pendant l'arrêt du compres-
seur en cas :
• D'installation en extérieur du compresseur,
• D'arrêts prolongés,
• D'un grand volume de fluide frigorigène,
• De risque de condensation de liquide frigorigène
dans le compresseur.
Les connexions se font conformément aux Informations
techniques KT-150.
Isoler le séparateur d'huile
L'opération à faibles températures ambiantes ou tem-
pératures élevées côté haute pression pendant les
temps d'arrêt (p. ex. pour les pompes à chaleur) néces-
site une isolation additionnelle du séparateur d'huile.
6 Mettre en service
Avant de sortir de l'usine, le compresseur est soigneu-
sement séché, son étanchéité contrôlée et il est rempli
de gaz de protection (N
2
).
DANGER
Danger d'explosion !
Le compresseur ne doit en aucun cas être mis
sous pression avec de l'oxygène (O
2
) ou
d'autres gaz techniques !
AVERTISSEMENT
Danger d'éclatement !
Risque de décalage critique de la limite d'inflam-
mabilité du fluide frigorigène en cas de surpres-
sion.
Ne pas mélanger de fluide frigorigène (par ex.
en tant qu'indicateur de fuite) au gaz d'essai (N
2
ou air).
Pollution en cas de fuite ou de dégonflement !
!
!
AVIS
Danger d'oxydation de l'huile !
Utiliser de préférence du nitrogène déshydraté
(N
2
) pour contrôler la résistance à la pression et
l'étanchéité de l'ensemble de l'installation.
En cas d'utilisation d'air séché : Mettre le com-
presseur hors-circuit – obligatoirement maintenir
les vannes d'arrêt fermée.
6.1 Contrôler la résistance à la pression
Contrôler le circuit frigorifique (groupe assemblé) selon
la norme EN378-2 ou toute autre norme de sécurité
équivalente également valable. Le compresseur a déjà
fait l'objet avant sa sortie d'usine d'un contrôle de sa ré-
sistance à la pression. Un simple essai d'étanchéité est
donc suffisant, voir chapitre Contrôler l'étanchéité, page
94. Si toutefois, l'ensemble du groupe assemblé doit
subir un contrôle de sa résistance à la pression :
DANGER
Danger d'éclatement dû à une trop grande pres-
sion !
La pression d'essai ne doit pas dépasser la
pression maximale admissible !
Pression d'essai : 1,1 fois la pression de service
maximale admissible (voir plaque de désigna-
tion). Différencier les côtés de haute et de
basse pression !
5.4.7 Подогреватель масла
Подогреватель масла обеспечивает смазывающую
способность масла даже после длительных периодов
простоя компрессора. Он предохраняет от повышения
концентрации хладагента в масле и таким образом от
снижения его вязкости.
Подогреватель масла должен быть включен в периоды
простоя компрессора, при:
• установке компрессора вне помещения,
• длительных периодах простоя,
• большой заправке хладагентом,
• опасности конденсации хладагента в компрессоре.
Подключение осуществляйте в соответствии с
технической информацией КТ-150.
Изоляция маслоотделителя
При эксплуатации при низких температурах окружающей
среды или при высоких температурах на стороне
высокого давления во время останова (например,
тепловые насосы) требуется дополнительная изоляция
маслоотделителя.
5.4.6 Предохранительные устройства для
ограничения давления (HP и LP)
• Необходимы для ограничения области применения
компрессора, для исключения недопустимых рабочих
условий.
• Ни в коем случае не подключать реле к сервисному
штуцеру на запорном клапане!
• Установите давление замыкания и размыкания в
соответствии с областью применения и выполните
тестовые проверки, чтобы точно их подтвердить.
6 Ввод в эксплуатацию
Компрессор на заводе-изготовителе уже тщательно
высушен, испытан на плотность и заполнен защитным
газом (N
2
).
ОПАСНОСТЬ
Возможен взрыв!
Ни в коем случае не допускается проводить
испытания компрессора кислородом (О
2
) или
другими промышленными газами!
ПРЕДУПРЕЖДЕНИЕ
Опасность разрыва!
Может произойти опасное снижение точки
воспламенения хладагента при высоком
давлении!
Никогда не добавляйте хладагент в газ для
испытания (N
2
или воздух) – например, как
индикатор утечек.
Возможны загрязнения окружающей среды
утечками хладагента при испытании контура и
при откачке испытательного газа!
ВНИМАНИЕ
Опасность окисления масла!
Испытание на прочность и плотность всей
системы предпочтительно проводить сухим
азотом (N
2
).
При использовании сухого воздуха:
компрессор должен быть отсечен от системы -
держите запорные клапаны закрытыми.
6.1 Испытание давлением на прочность
Испытайте смонтированный холодильный контур
согласно указанию, EN 378-2 (или другому
действующему стандарту безопасности). Компрессор
уже был испытан на прочность давлением на
заводе-изготовителе. Поэтому достаточно провести
испытание на плотность, смотрите главу Испытание
на плотность, страница 27. Однако, если вся система
испытывается давлением на прочность:
ОПАСНОСТЬ
Опасность разрыва из-за высокого давления!
Пробное давление не должно превышать
максимально допустимых значений!
Пробное давление: 1,1*максимально
допустимое рабочее давление (смотрите
заводскую табличку). При этом разделяйте
сторону высокого и низкого давления!

Opto-electronic oil level monitoring OLC-D1-S
The OLC-D1-S is an opto-electronic proximity sensor
that monitors the oil level with infrared light. Depending
on the mounting position and electrical connection, the
same unit can be used for monitoring the minimum and
maximum oil levels.
The monitoring device comprises two parts: a prism
unit and an opto-electronic unit.
• The prism unit – a glass cone is mounted directly
into the compressor housing.
• The opto-electronic unit is designated as OLC-D1. It
is not directly connected to the refrigerating circuit. It
is screwed into the prism unit and integrated in the
system's control logic. No external control device is
required.
Delivery in a pre-setup state
If the prism unit of the OLC-D1-S has been ordered
pre-assembled, the compressor will have already been
tested as a whole in the factory for strength pressure
and tightness. In this case, it will only be necessary to
screw in the opto-electronic unit and to connect it elec-
trically (see Technical Information ST-130). Sub-
sequent tightness testing will not be required in this
case.
When retrofitting, both prism and electronic unit must
be mounted. For a detailed mounting description,
please see Technical Information ST-130.
5.4.6 Safety devices for pressure limiting (HP and LP)
• These safety devices are required for securing the
compressor's application range in order to avoid un-
acceptable operating conditions.
• Do not connect any safety devices to the mainten-
ance connection of the shut-off valve!
• Set cut-in and cut-out pressures according to the ap-
plication limits and perform a test to exactly check
them.
5.4.7 Oil heater
The oil heater ensures the lubricity of the oil even after
long standstill periods. It prevents increased refrigerant
concentration in the oil and therefore reduction of vis-
cosity.
The oil heater must be operated while the compressor
is at standstill in case of
• outdoor installation of the compressor,
• long shut-off periods,
• high refrigerant charge,
• possible refrigerant condensation in the compressor.
Connection according to Technical Information KT-150.
Isolating the oil separator
Operating at low ambient temperatures or with high
temperatures on the high-pressure side during stand-
still (e.g. for heat pumps) requires additional isolation of
the oil separator.
6 Commissioning
The compressor has been carefully dried, checked for
tightness and filled with a holding charge (N
2
) before
leaving the factory.
DANGER
Risk of explosion!
Never pressurize the compressor with oxygen
(O
2
) or other industrial gases!
WARNING
Risk of bursting!
A critical shift of the refrigerant ignition limit is
possible in case of excess pressure.
Do not add a refrigerant (e.g. as a leak indic-
ator) to the test gas (N
2
or air).
Environmental pollution in case of leakage and
when deflating!
!
!
NOTICE
Risk of oil oxidation!
Check the entire system for strength pressure
and tightness, preferably using dried nitrogen
(N
2
).
When using dried air: Remove the compressor
from the circuit – make sure to keep the shut-off
valves closed.

SB-170-9 27
6.1 Checking pressure strength
Check the refrigerant circuit (assembly) according to
EN378-2 (or other applicable equivalent safety stand-
ards). The compressor had been already tested in the
factory for strength pressure. A tightness test is there-
fore sufficient, see chapter Checking tightness, page
27. If you still wish to perform a strength pressure test
for the entire assembly:
DANGER
Risk of bursting due to excessive pressure!
The pressure applied during the test must never
exceed the maximum permitted values!
Test pressure: 1.1-fold of the maximum allow-
able pressure (see name plate). Make a distinc-
tion between the high-pressure and low-pres-
sure sides!
6.2 Checking tightness
Check the refrigerant circuit (assembly) for tightness,
as a whole or in parts, according to EN378-2 (or other
applicable equivalent safety standards). For this, create
an excess pressure, preferably using dried nitrogen.
Observe test pressures and safety reference, see
chapter Checking pressure strength, page 27.
6.3 Evacuation
• Switch on the oil heater.
• Open all shut-off valves and solenoid valves.
• Use a vacuum pump to evacuate the entire system,
including the compressor, on the suction side and
the high-pressure side.
With the vacuum pump shut off, a "standing vacuum"
lower than 1.5 mbar must be achieved.
• Repeat the operation several times if necessary.
!
!
NOTICE
Risk of damage to the motor and compressor!
Do not start the compressor while it is in a va-
cuum!
Do not apply any voltage, not even for testing!
6.4 Charging refrigerant
Use only permitted refrigerants, see see chapter Ap-
plication ranges, page 5.
DANGER
Risk of bursting of components and pipelines
due to hydraulic excess pressure while feeding
liquid.
Serious injuries are possible.
Avoid overcharging the system with refrigerant
under all circumstances!
WARNING
Risk of bursting due to counterfeit refrigerants!
Serious injuries are possible!
Purchase refrigerants only from reputable man-
ufacturers and reliable distributors!
!
!
NOTICE
Risk of wet operation during liquid feeding!
Measure out extremely precise quantities!
Maintain the discharge gas temperature at least
20 K above the condensing temperature.
➙ Before charging with refrigerant:
➙ Do not switch on the compressor!
➙ Switch on the oil heater.
➙ Check the oil level in the compressor.
• Fill liquid refrigerant directly into the condenser or re-
ceiver; on systems with flooded evaporator, maybe
directly into the evaporator.
• Blends must be taken out of the charging cylinder as
a solid liquid.
• After commissioning, it may be necessary to add re-
frigerant: While the compressor is running, charge
with refrigerant on the suction side, preferably at the
evaporator inlet. Blends must be taken out of the
charging cylinder as a solid liquid.
