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.
Monitoring functions:
• Temperature monitoring.
• Monitoring of the PTC control circuit to detect any
short-circuit or line break/sensor failure.
• Rotation direction monitoring.
• Monitoring of phase failure and asymmetry.
• Monitoring of the maximum cycling rate.
For further information, see Technical Information
CT-110.
5.4.4 SE-E2
Optional protection device for operation with frequency
inverter and soft starter (for a ramp time shorter than
1 s).
• 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.

8.3 Soupape de décharge incorporée
La soupape ne nécessite aucune maintenance. Elle af-
fiche une différence de pression de réponse de 28 bar.
Cependant, en cas de dégonflement répété en raison
de conditions de fonctionnement anormales, une fuite
permanente est possible. Résultat, les performances
sont réduites et la température du gaz de refoulement
augmente.
8.4 Clapet de retenue incorporé
Après l'arrêt, le compresseur fonctionne un court ins-
tant en sens inverse (environ 5 s, jusqu'à l'égalisation
de pression dans le séparateur d'huile). En cas de dys-
fonctionnement ou d'encrassement, ce temps s'allonge.
Le clapet doit alors être remplacé.
AVERTISSEMENT
Le compresseur est sous pression !
Risque de blessures graves.
Évacuer la pression du compresseur !
Porter des lunettes de protection !
Position de montage : dans la sortie du gaz de refoule-
ment au dessous de la vanne d'arrêt de refoulement ou
le raccord de tube. Remplacement voir instructions de
maintenance SW-170.
9 Mettre hors service
9.1 Arrêt
Laisser le réchauffeur d'huile en marche jusqu'au dé-
montage. Cela évite un trop grand enrichissement de
l'huile en fluide frigorigène.
AVERTISSEMENT
Risque d'évaporation du fluide frigorigène à par-
tir de l'huile.
En fonction du fluide frigorigène, risque accru
dû à l'inflammabilité !
Les compresseurs arrêtés et l'huile usée
peuvent encore contenir une quantité relative-
ment importante de fluide frigorigène dissous.
Fermer les vannes d'arrêt et aspirer le fluide fri-
gorigène !
9.2 Démontage du compresseur
AVERTISSEMENT
Le compresseur est sous pression !
Risque de blessures graves.
Évacuer la pression du compresseur !
Porter des lunettes de protection !
Fermer les vannes d'arrêt du compresseur. Aspirer le
fluide frigorigène. Ne pas dégonfler le fluide frigorigène
mais l'éliminer dans le respect de l'environnement !
Retirer les assemblages à vis ou la bride des vannes
du compresseur. Retirer le compresseur de l'installa-
tion, si nécessaire en utilisant un engin de levage.
8.3 Встроенный предохранительный клапан
Данный клапан обслуживанию не подлежит. Его
давление срабатывания составляет 28 bar.
Однако, многократное повторное срабатывание
данного клапана в результате ненормальных
условий эксплуатации может привести к постоянным
перетечкам. Следствием этого будет являться падение
производительности и рост температуры нагнетания.
8.4 Встроенный обратный клапан
После выключения компрессор в течение короткого
промежутка времени работает в обратном направлении
(примерно 5 сек, до достижения выравнивания давления
в маслоотделителе). При дефекте или загрязнении
обратного клапана этот период удлиняется. В этом
случае необходимо заменить клапан.
ПРЕДУПРЕЖДЕНИЕ
Компрессор находится под давлением!
Возможны серьезные травмы.
Сбросьте давление в компрессоре!
Наденьте защитные очки!
Место установки: Фланец на выходе нагнетаемого газа
маслоотделителя. Сначала демонтируйте запорный
клапан на нагнетании. Подробную информацию
смотрите в инструкции по обслуживанию SW-170.

NOTICE
Risk of damage to the compressor.
Tighten screws and nuts only to the prescribed
tightening torque and, if possible, crosswise in
at least 2 steps.
• Charge with new oil.
• Test tightness before commissioning.
8.3 Integrated pressure relief valve
The valve is maintenance-free. Its response pressure
difference is 28 bar.
However, after repeated venting, it may leak perman-
ently because of abnormal operating conditions. The
consequences are reduced performance and a higher
discharge gas temperature.
8.4 Integrated check valve
After being shut off, the compressor runs reverse for a
short time (approx. 5 s, until pressure compensation in
the oil separator takes place). When the check valve is
damaged or clogged, this time extends. The valve must
then be changed.
WARNING
The compressor is under pressure!
Serious injuries are possible.
Depressurize the compressor!
Wear safety goggles!
Mounting position: in discharge gas outlet flange below
the discharge shut-off valve or pipe connection. Re-
placement see maintenance instructions SW-170.
9 Decommissioning
9.1 Standstill
Leave the oil heater switched on until disassembly.
This prevents increased refrigerant concentration in the
oil.
WARNING
Risk of refrigerant evaporation from the oil.
Increased risk of flammability, depending on the
refrigerant!
Shut-down compressors or used oil may still
contain rather high amounts of dissolved refri-
gerant.
Close the shut-off valves on the compressor
and extract the refrigerant!
9.2 Dismantling the compressor
WARNING
The compressor is under pressure!
Serious injuries are possible.
Depressurize the compressor!
Wear safety goggles!
Close the shut-off valves on the compressor. Extract
the refrigerant. Do not deflate the refrigerant, but dis-
pose of it properly!
Loosen screwed joints or flanges on the compressor
valves. Remove the compressor from the system; use
hoisting equipment if necessary.
9.3 Disposing of the compressor
Drain the oil from the compressor. Dispose of waste oil
properly! Have the compressor repaired or dispose of it
properly!
When returning compressors that have been operated
with flammable refrigerant, mark the compressor with
the symbol "Caution flammable gas", as the oil may still
contain refrigerant.
