1 Safety instructions
Intended use
The module and the measurement modules and transducers connected to it
must only be used for measurements and directly related control and regulation
tasks. Use for any purpose other than the above is deemed improper use.
In the interests of safety, the module must only be used as described in the
operating manual. When the module is in use, it is essential to comply with the
applicable legal and safety requirements for the relevant application. The same
applies to the use of accessories.
Before starting up the module for the first time, you must first run a project
planning and risk analysis that takes into account all the safety aspects of
automation technology. This particularly concerns personal and machine
protection.
Additional safety precautions must be taken in plants where malfunctions could
cause major damage, loss of data or even personal injury. If an error occurs,
these precautions will ensure that safe operating conditions have been
established.
This can be achieved, for example, through mechanical interlocking, fault
messages, limit value switches, and similar things.

Safety instructions
CX27C-R A05417_02_E00_01 HBM: public 5
Safety requirements
A module must not be directly connected to a power supply system. The
allowed supply voltage range is:
SCX Module 10 DC ... 30 DC
SEX23-R 10 DC ... 36 DC
SMX Module 10 DC ... 30 DC
SUPX Module 10 DC ... 30 DC
The supply voltage connection as well as the signal and sense leads must be
installed in such a way that electromagnetic interference does not adversely
affect device functionality. (HBM recommendation: "Greenline shielding
design", can be downloaded from http://www.hbm.com/greenline).
Automation equipment and devices must be covered over in such a way that
adequate protection or locking against unintentional actuation is provided (e.g.
access checks, password protection, etc.).
When devices are working in a network, these networks must be designed in
such a way that interference in individual nodes can be detected and the nodes
can be shut down.
Safety precautions must be taken both in terms of hardware and software, so
that a line break or other interruptions to signal transmission, e.g. via the bus
interfaces, do not cause undefined states or loss of data in the automation
device.
Conditions on site
For all modules:
SPlease observe the maximum allowed ambient temperatures stated in the
specifications.
SMake sure that the device is exposed to as little direct sunlight as possible
in hot operating environments.

Safety instructions
6A05417_02_E00_01 HBM: public CX27C-R
Maintenance and cleaning
The modules are maintenance-free. Note the following points when cleaning
the housing:
SBefore cleaning, disconnect the module from all connections.
SClean the housing with a soft, slightly damp (not wet!) cloth. You should
never use solvents, since they could damage the label on the front panel
and damage the display.
SDo not subject the device to high water pressure while cleaning.
General dangers of failing to follow the safety instructions
The module is a state of the art device and as such is failsafe. The module
may give rise to residual dangers if it is inappropriately installed and operated
by untrained personnel. Any person instructed to carry out installation, start-up,
maintenance or repair of the module must have read and understood the
operating manual and in particular the technical safety instructions.
Residual dangers
The scope of supply and performance of the module covers only a small area
of measurement technology. In addition, equipment planners, installers and
operators should plan, implement and respond to the safety engineering
considerations of measurement technology in such a way as to minimize
residual dangers. On-site regulations must be complied with at all times. There
must be reference to the residual dangers connected with measurement
technology. After making settings and carrying out activities that are password-
protected, you must make sure that any controls that may be connected
remain in safe condition until the switching performance of the module has
been tested.
Product liability
In the following cases, the protection provided for the device may be adversely
affected. Liability for equipment functionality passes to the operator when:
SThe device is not used in accordance with the operating manual.
SThe device is used outside the field of application described in this chapter.
SThe operator makes unauthorized changes to the device.

4.1 Power supply
Connect a DC supply voltage of 10 - 30 V to connector X104. Use a voltage
supply with sufficient power if any MX modules connected to the CX27C-R
also need to be supplied.
The DC voltage supply must be a SELV voltage supply, meeting the require
ments of IEC/EN/DIN EN 609501. The supply voltage must be protected by
an adequate DC fuse (e.g. LITTELFUSE KLKD 6, LFPHV001) with a maximum
current of 5 A.
HBM offers the NTX002 power supply for laboratory or general steady-state
operation. On the primary side, this provides a selection of international
connector types and 24 V and 30 watts on the secondary side. A CX27C-R
and two additional MX modules can be supplied in this way.
4.2 Ground connection and grounding
Lay the signal and data leads separately from the current-carrying power line.
Cable ducts made of sheet metal with an internal partition are ideal.
When there are differences in potential in or at the connected measurement
system, you will have to integrate the CX27C-R into the potential equalization
line through the functional earth connector.
4.3 Connecting the measurement modules
The SomatXR module CX27C-R is a so-called gateway. A gateway is used so
that networks based on completely different protocols can communicate with
each other.
Thus the main task of the Industrial Ethernet gateway CX27C-R is to receive
and forward data from the modules connected via FireWire.
Data is transmitted via the FireWire connections and the module is synchro
nized for time and supplied with the optimum voltage. Data transmission is
asynchronous (all nodes) or isochronous (to a specific node, e.g. CX27C-R).
You can connect a total of twelve modules with each other in series via
FireWire.

Connections and displays
14 A05417_02_E00_01 HBM: public CX27C-R
SomatXR or QuantumX modules are connected to the gateway via FireWire.
Connect cable 1-KAB272-x to any of the gateway’s connectors and the other
end to connector X102 of the first measurement module.
Then keep threading: connector X101 to X102 of the second measurement
module, etc. You will usually have to provide another voltage supply after three
modules. The supply voltage of the modules is connected through FireWire
(maximum 1.5 A via FireWire). The power consumption of a module is
explained in the data sheet. The supply voltages in a system should all have
about the same voltage value.
4.4 Inclusion of Industrial Ethernet fieldbus and
connection to PC.
The CX27C-R Gateway has two Ethernet interfaces and one fieldbus interface
(IN/OUT) for a network connection. The Ethernet interfaces on the front and
back of the module are equivalent, and are implemented as M12 sockets
(X coded).
Ethernet M12 X coded RJ45

RX_D2- 4 6
BI_D3+ 7 4
BI_D3- 8 5
BI_D4+ 5 7
BI_D4- 6 8
Generally, only one of the two Ethernet interfaces should be used in order to
prevent problems with the network configuration.
Measurement tasks: central interface for all connected modules and their
measured values.
Maintenance tasks: central interface for all connected modules for diagnosis or
updates.
