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.

• 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.

d'arrêt fermées jusqu'à la mise sous vide.
4.3.1 Raccordements de tuyauterie
Les raccordements sont exécutés de façon à ce que
les tubes usuels en millimètres et en pouces puissent
être utilisés. Les raccords à braser ont plusieurs dia-
mètres successifs. Suivant la section, le tube sera insé-
ré plus ou moins profon - dément. Si nécessaire, l'ex-
trémité avec le plus grand diamètre peut être sciée.
4.3.2 Vannes d'arrêt
ATTENTION
En fonction de l'utilisation, les vannes d'arrêt
sont susceptibles d'être très froides ou très
chaudes.
Risque de brûlure ou de gelure !
Porter une protection appropriée !
!
!
AVIS
Ne pas surchauffer les vannes d'arrêt !
Refroidir les vannes et l'adaptateur de brasage
pendant et après le brasage.
Température de brasage maximale : 700°C !
Pour souder, démonter les raccords de tubes et

en croix, en 2 étapes minimum.
Avant la mise en service, essayer l'étanchéité !
Lors du montage ultérieur de la vanne d'arrêt ECO :
Information
Pour augmenter la protection anticorrosion, il
est conseillé de peindre la vanne d'arrêt ECO.
4.3.3 Conduites
En règle générale, n’utiliser que des conduites et des
composants d’installation qui
• sont propres et secs à l’intérieur (sans calamine, ni
copeaux de métal, ni couches de rouille ou de phos-
phate) et
• qui sont livrés hermétiquement fermés.
Selon la version, les compresseurs sont livrés avec des
rondelles de fermeture au niveau des raccords de tube
ou des vannes d’arrêt. Avant de contrôler la résistance
à la pression et l’étanchéité et de mettre le système en
service, il faut retirer ces rondelles.
Information
Les rondelles de fermeture ne sont conçues que
comme protection pour le transport. Elles ne
sont pas faites pour séparer les différents tron-
çons de l'installation durant l'essai de résistance
à la pression.
!
!
AVIS

NOTICE
Risk of compressor damage!
Generously sized filter dryers should be used to
ensure a high degree of dehydration and to
maintain the chemical stability of the circuit.
Make sure to choose a suitable quality (molecu-
lar sieves with specially adapted pore sizes).
Information
Notice for mounting the suction-side cleaning fil-
ter, see manual SH-170.
