Safety instructions
Use in accordance with the regulations
The ML71BS6 CAN bus module is to be used exclusively for measurement
tasks and directly related control tasks. Use for any purpose other than the
above shall be deemed to be not in accordance with the regulations.
To ensure safe operation, the device may only be operated in accordance with
the information given in the Operating Manual. It is also essential to comply
with the legal and safety requirements for the application concerned during
use. The same applies to the use of accessories.
General dangers of failing to follow the safety instructions
The ML71BS6 CAN bus module complies with the state of the art and is
fail-safe. The device may give rise to further dangers if it is inappropriately
installed and operated by untrained personnel.
Any person instructed to carry out installation, commissioning, maintenance or
repair of the device must have read and understood the Operating Manual
and in particular the technical safety instructions.
Remaining dangers
The scope of performance and supply of the ML71BS6 only covers part of the
range of measurement technology. In addition, equipment planners, installers
and operators should plan, implement and respond to the safety engineering
considerations of measurement technique in such a way as to minimise
remaining dangers. Prevailing regulations must be complied with at all times.
There must be reference to the remaining dangers connected with
measurement technique.
In this manual, the following symbols are used to draw your attention to any
remaining dangers that might occur when working with the ML71BS6:
Symbol:
WARNING
Meaning: Dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements can lead to death or serious physical injury.

Symbol:
Meaning: CE mark
The CE mark enables the manufacturer to guarantee that the product com-
plies with the requirements of the relevant EC directives (the declaration of
conformity is available at http://www.hbm.com/HBMdoc).
Working safely
Error messages must only be acknowledged when the cause of the error has
been removed and no further danger exists.
The device complies with the safety requirements of DIN EN 61010-Part 1
(VDE 0411-Part 1); Protection Class I.
To ensure adequate immunity from interference, use only Greenline shielded
ducting (see HBM offprint ”Greenline shielding design, EMC-compliant measuring cable; G36.35.0)

Conversions and modifications
No modifications that affect the design or the technical safety of the ML71BS6
CAN bus module may be carried out without our express agreement. Any
modification shall exclude all liability on our part for any resulting damage.
In particular any repair or soldering work on motherboards is prohibited. When
exchanging complete modules, use only original parts from HBM.
Qualified personnel
This instrument must only to be installed and used by qualified personnel,
strictly in accordance with the technical data and the safety requirements and
regulations listed. It is also essential to comply with the legal and safety
requirements for the application concerned during use. The same applies to
the use of accessories.
Qualified personnel means persons entrusted with the installation, assembly,
commissioning and operation of the product who possess the appropriate
qualifications for their function.
Maintenance and repair work on an open device with the power on must only
be carried out by trained personnel who are aware of the danger involved.

1 Introduction
The ML71BS6 is an MGCplus system module that takes measurement data
from the MGC and outputs it as CAN messages. It records up to 128
measured values per CAN port, scales them and outputs them at the CAN
bus.
Two independent CAN interfaces per channel and two different physical layers
(ISO 11898−24V and a ”low-speed” link based on the Philips TJA1053
transceiver module) are supported.
The measurement data to be transmitted can be selected either by using the
AB22A/AB32 display and control panel or by using the “MGCplus Assistant”
software from HBM.
