5.7 Wiring in the state of delivery

Interventions on components that are delivered wired
and on their electrical connections are not necessary.
They are fully installed and wired at delivery:
5.7.1

HS.95: pre-fitted components

• Slider position indicator (B70)
• Solenoid valves for capacity control and V
M12, M15 and M16)
• Low pressure and high pressure transmitters (B51
and B50)
• Discharge gas temperature sensor (B02)
• Oil monitoring (OLC-D1, B30)
• Oil pressure transmitter (B54)
• Motor temperature monitoring (B03 to B08)
• Rotation direction monitoring
5.7.2

CSW105: pre-fitted components

i • Oil filter monitoring (B42)

5.8 High pressure switch

According to EN378, each compressor must be
provided with a high pressure switch (B10) for safety
cut-out in the safety chain. Depending on the displace-
ment and refrigerant charge, it must be designed as a
safety pressure cut-out and / or only as pressure cut-
out. The software-controlled monitoring of the com-
pressor module via the high pressure transmitter (B50)
does not sufficiently ensure the safety cut-out function.
The high pressure switch (B10) should preferably be
connected to terminal strip CN3. The data are analysed
and logged in this case.
The installation of a low pressure switch is not neces-
(M11,
i sary, depending on local regulations. The compressor
module is provided with an automatic low pressure cut-
out function.
