Safety instructions

1 Safety instructions
Notice
The safety instructions described here also apply to the
power pack NTX001 and the active backplane BPX001
and BPX002.
Appropriate use
A module integrated into the CANbus by the relevant
connector is to be used exclusively for measurement and
test tasks. Use for any purpose other than the above is
deemed to be non-designated use.
To ensure safe operation, the module must only be ope
rated as described in the general operating manual and in
accordance with the information detailed in this document.
It is also essential to comply with the legal and safety re
quirements for the application concerned during use. The
same applies to the use of accessories.
Each time you start up the module, you must first run a
project planning and risk analysis that takes into account
all the safety aspects of automation technology. This par
ticularly 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. In the event of a fault, these
precautions establish safe operating conditions.
This can be done, forexample, by mechanical
interlocking, error signaling, etc.

Safety instructions
6A4461-2.0 HBM: public CANBus
Notice
The module must not be connected directly to a power
supply system. The supply voltage must be 10 V … 30 V
(DC).
General dangers of failing to follow the safety
instructions
Every module is a state of the art device and as such is
failsafe. 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,
commissioning, maintenance or repair of the modules
must have read and understood the Operating Manuals
and in particular the technical safety instructions.
The scope of supply and performance of the modules
only covers 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.

Safety instructions
CANBus A4461-2.0 HBM: public 7
Maintenance and cleaning
The modules are maintenance-free.
SBefore cleaning, disconnect all connections.
SClean the housing with a soft, slightly damp (not wet!)
cloth. Never use solvent, as this could damage the
label or the housing.
SWhen cleaning, ensure that no liquid gets into the
module or connections.
Bus connecting and Outputs
Particular attention must be paid to safety when
connecting to the CANbus and when sending CANbus
messages. Ensure that integration alone, status or
control signals cannot initiate any actions that may pose
a danger to persons or the environment.
Product liability
In the following cases, the protection provided for the
device may be adversely affected. Liability for device
functionality then passes to the operator:
SThe device is not used in accordance with the operat
ing manual.
SThe device is used outside the field of application de
scribed in this section.
SThe operator makes unauthorized changes to the
device.
Warning signs and danger symbols
Important instructions for your safety are specifically
identified. It is essential to follow these instructions in
order to prevent accidents and damage to property.

Safety instructions

CANBus A4461-2.0 HBM: public 9
Working safely
The supply connection, as well as the signal and sensor
leads, must be installed in such a way that
electromagnetic interference does not adversely affect
device functionality (HBM recommendation: "Greenline
shielding design", downloadable from the Internet at
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 malfunctions in
individual nodes can be detected and 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.
Error messages should only be acknowledged once the
cause of the error is removed and no further danger
exists.
Conversions and modifications
The module must not be modified from the design or
safety engineering point of view except with our express
agreement. Any modification shall exclude all liability on
our part for any resultant damage.
In particular, any repair or soldering work on
motherboards (exchanging components) is prohibited.
When exchanging complete modules, use only original
parts from HBM.

Safety instructions
10 A4461-2.0 HBM: public CANBus
The module is delivered from the factory with a fixed
hardware and software configuration. Changes can only
be made within the possibilities documented in the
manuals.

This manual is intended to support you in connecting
your QuantumX or SomatXR system to a CANbus with
the following modules:
- MX471B(-R)
- MX840B(-R)
In the following we will refer to these modules as
MX471B and MX840B and only state the SomatXR
modules in case of significant differences.
When using the CX23-R data recorder there are some
restrictions related to the CANbus options (see CX23-R
manual).
The catmanEASY or MX Assistant software packages
have extensive online Help and can be used to configure
a CAN port.

5 QuantumX / SomatXR and CAN
5.1 General information
The MX471B module provides four independent CAN
bus nodes that are all electrically isolated from each
other and power supply. Module MX840B provides an
electrically isolated CANbus node on channel 1.
Connected devices are not directly addressed during
data transmission on a CAN bus. A unique identifier de
notes the contents of a message (e.g. rotational speed or
engine temperature).
The identifier also signifies the priority of the message.
Message = identifier + signal + additional information
Device connected to the bus = node
Each node on the MX471B can be parameterized either
as a receiver or as transmitter (gateway). The online help
that comes with the respective software package
provides detailed information about parameterization.
Notice
To ensure normal operation, the CAN bus needs to be
terminated at both ends, and only there, using appropri
ate termination resistors.
A 120-ohm termination resistor can be individually con
nected in the module by software. Termination is also
required when short cables with low bit rates are used.
Please refer to the data sheet for the relation between bit
rate and maximum bus line length.

QuantumX / SomatXR and CAN
CANBus A4461-2.0 HBM: public 17
The configuration of a node is retained after switching the
modules off and on.
For decoding signals at a rate greater than 2000/s,
please set up signal inputs 1 to 8 on the MX471B. The
signal buffers of these signal inputs have been expanded
accordingly.
