Peripheral devices
The compressor module is delivered pre-installed if
ordered with the compressor. It is an option for recip-
rocating compressors of the following series:
• 4FES-3(Y) to 8FE-70(Y): Compressors for standard
refrigerants
• 4PTE(U)-6(L)K to 6CTE(U)-50(L)K: Compressors for
transcritical CO

applications
Depending on the compressor series, different peri-
pheral devices can be combined. Peripheral devices
ordered with the compressor are delivered either fully
installed, pre-mounted or enclosed with the delivery,
depending on the unit. They can also be retrofitted.
All peripheral devices that can be operated with the
CM-RC-01 and the respective compressor series are
listed in the following tables: see chapter Peripheral
devices for compressors for standard refrigerants, page
9 and see chapter Peripheral devices for com-
pressors for transcritical CO
4.1
Standard
These peripheral devices are supplied as standard with
the compressor module and are essential for operation
with CM-RC-01. They are supplied fully assembled and
electrically connected if the respective compressor is
ordered with CM-RC-01. If a compressor module is ret-
rofitted, these components must also be mounted and
electrically connected to the CM-RC-01.
4.2
Options
These peripheral devices extend the operating and
monitoring capabilities of the CM-RC-01. If ordered with
the compressor, they are delivered pre-assembled and
electrically connected, if possible. They can also be ret-
rofitted.
Capacity control and start unloading: If a cylinder bank
is equipped with start unloading, it is no longer avail-
able for capacity control. A 4-cylinder compressor can
be equipped with a maximum of either 2 CRII capacity
regulators (variant A) or with start unloading and an ad-
ditional capacity regulator (variant B).
Peripheral devices that are not factory assembled and
electrically connected must always be activated with
the BEST SOFTWARE, see chapter Activating peri-
pheral devices, page 28.
