.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

• 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.

.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.

.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.

.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.
