5 Mounting and activation of the completion sensor kit
WARNING
The compressor is under pressure!
Serious injuries are possible.
Depressurize the compressor!
Wear safety goggles!
5.1 Mounting the components of the completion
sensor kit to CS. compressors
The wired and connected CS. screw compressors, ex-
cept for CSHP compressors, can be ordered ex factory
either with the SE-i1 basic sensor kit or with the full
sensor kit. Scope of functions, see chapter Monitoring
functions, protective functions and extent of delivery,
page 4.
Therefore, all components of the completion sensor kit
must be mounted to the compressor only if:
• the basic sensor kit is to be upgraded to the full func-
tionality of the full sensor kit.
