1 Safety instructions
Appropriate use
A CANHEAD module with connected sensors or transducers is to be used ex
clusively for measurement tasks and related control tasks .Use for any purpose
other than the above shall be deemed to be inappropriate.
In the interests of safety, the device should only be operated as described in
the Operating Manual. It is also essential to observe the appropriate legal and
safety regulations for the application concerned during use. The same applies
to the use of accessories.
Each time, before starting up the equipment, you must first run a project plan
ning and risk analysis that takes into account all the safety aspects of automa
tion 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. In the event of a
fault, these precautions establish safe operating conditions.
This can be done, for example, by mechanical interlocking, error signaling, limit
value switches, etc.
Conditions on site
SProtect the device from direct contact with water.
SProtect the CANHEAD system from humidity or effects of the weather such
as rain, snow, etc. The equipment complies with protection class IP20 per
DIN EN 60 529. Connection threads in the housing need to be locked during
operation.
SDo not expose the instrument to direct sunlight.
SObserve the maximum permissible ambient temperatures given in the spe
cifications.
SThe permissible relative humidity at 31 ºC is 80 % (non condensing); linear
reduction down to 50 % at 40 ºC.
SThe devices are classed as overvoltage category II, pollution grade 2 equip
ment.

Safety instructions
6A01185_11_X00_00 HBM: public CANHEAD
SPlace the device so that it can easily be disconnected from the mains at any
time.
SThe CANHEAD system can be safely operated up to a height of 2000 m
General dangers of failing to follow the safety instructions
The device is a state of the art unit and as such is reliable. The module may
give rise to dangers if it is inappropriately installed and operated by untrained
personnel.
Any person instructed to carry out installation, starting up, maintenance or
repair of the module must have read and understood the Operating Manual
and in particular the technical safety instructions.
Maintenance and cleaning
The CANHEAD system is maintenance‐free.
SBefore cleaning, disconnect the equipment completely.
SClean the housing with a soft, slightly damp (not wet!) cloth. Never use
solvents, since these could damage the labelling on the front panel and the
display.
SWhen cleaning, ensure that no liquid gets into the equipment or connec
tions.
Residual dangers
The scope of supply and performance of the CANHEAD system 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 remaining dangers. On-site regulations must be complied with at all
times. There must be reference to the remaining dangers connected with
measurement technology.
Safety rules
The supply connection, as well as the signal and sense leads, must be
installed in such a way that electromagnetic interference does not adversely

CANHEAD A01185_11_X00_00 HBM: public 7
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 (such
as 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, such as via the
bus interfaces, do not cause undefined states or loss of data in the automation
device.
Conversions and modifications
The device must not be modified from the design or safety engineering point of
view except with our express agreement. Any modification shall exclude all lia
bility on our part for any damage resulting therefrom.
In particular, any repair or soldering work on motherboards is prohibited. When
exchanging complete modules, use only original parts from HBM.
The product is delivered from the factory with a fixed hardware and software
configuration. Changes can only be made within the possibilities documented
in the manuals.
Qualified personnel
Qualified persons means persons entrusted with the installation, fitting, com
missioning and operation of the product who possess the appropriate qualifica
tions for their function.
This device is only to be installed and used by qualified personnel, strictly in
accordance with the specifications and the safety rules and regulations.
This includes people who meet at least one of the three following requirements:

Safety instructions

4 Field of application
The CANHEAD system is 10‐channel measurement electronics for quar
ter‐bridge, half‐bridge, and full‐bridge strain gages, DC voltage sources and
strain gage‐based transducers.
The special feature of HBM's CANHEAD concept is the separate assembly of
the base module and the plug‐in amplifier module.
SBase module
Sfor wiring the SG or transducer connection cables
Base modules for SG‐quarterbridges (CB1014, CB1015) are available for all
the standard SG resistance values (120, 350, 700, 1000 
SAmplifier module
Sfor implementing highly‐sensitive and precise measurements
So when installing the strain gages ‐ for example, in experimental stress analy
sis ‐ the base module (with all the wiring) is connected to the strain gages first.
This allows the the amplifier module to be used for other measuring tests until
its ultimate involvement. It is also possible to remove the amplifier module with
out the intelligent base module losing the measuring point specific data that
has been saved.

Notice
Avoid electrostatic discharge! Ensure that any person or object is electrostati
cally discharged by touching a grounded object, before touching the CAN
HEAD module during measurement. Non‐observance may result in invalid
measured values being supplied for up to 200 ms.

Bus configuration
CANHEAD A01185_11_X00_00 HBM: public 15
5 Bus configuration
With a bus system, intelligent measurement electronics are interconnected or
connected to the central evaluator and server / PC by a data line.
A CAN bus with a fixed baud rate has been chosen for the transfer of data
generated in the base module and in the amplifier module. This gives the opti
mum ratio between management data, parameterization data and process data
(measured values) with at the same time faster data transfer rates and greater
bus lengths.
The bus allows cyclic and acyclic data to be transferred. This ensures that the
synchronized AD converter operating in parallel can process in real time. A
HBM specific CAN protocol is used for data transport of up to 12 CANHEADs
in one bus line.
5.1 Bus configuration with MGCplus
The master here is the ML74B communications module, to read the data into
an MGCplus system. In conjunction with catman measurement software, this

5.2 Bus configuration with CANHEADdirect
CANHEADdirect includes a hardware interface and an API (Application Pro
gramming Interface). The CANHEADdirect module enables CANHEAD mod
ules to be directly connected to a PC (USB port).
A power supply unit provides the voltage (10...30 V) for the CANHEADdirect
module. A CAN bus is used for data transmission between the CANHEAD
modules and the CANHEADdirect (see chapter 9).
The PC-internal API uses CANopen protocol for communication with the CAN
HEAD modules. CANHEADdirect enables the CAN bus voltage supply to be
switched on and off to reset the bus.
An example program can be used to check the system functions and parame
terize the sensors using HBM's catman software.
