1 Safety instructions
Appropriate use
The MVD2555 with the connected transducers may be used for measurement
and directly related control and regulation tasks, only. Any other use is not
appropriate. To ensure safe operation, the transducer may only be used
according to the specifications given in this 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.
Each time, before starting up the equipment, 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. 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.
WARNING
Due to the fact that the device has not been equipped with a proper mains
switch, the supply cable must not be connected directly to the mains. VDE
guidelines require that the device can be disconnected from the mains via a
switching device (doublebreak disconnector). It is essential that the discon
nector is labeled accordingly and easy to access and operate by the user.
Before connecting the device, make sure that the mains voltage and current
type specified on the name plate correspond to the mains voltage and current
type at the site of installation and that the current circuit used is sufficiently
safe.
Devices designed for panel mounting may only be operated in an EMC-tested
control cabinet. (see page 16).
The device complies with the safety requirements of DIN EN 61010-part1
(VDE 0411-part1); protection class I.

General dangers in the case of non-observance of the safety
instructions
The MVD2510 complies with the state of the art and is operationally reliable. If
the device is used and operated inappropriately by untrained personnel,
residual dangers might develop.
Any person charged with device installation, operation, maintenance or repair
must in any case have read and understood the operating manual and the
safety instructions, in particular.
Conditions on site
−Protect the device from direct contact with water.
−Protect the PMX system from moisture and humidity or weather conditions
such as rain, snow, etc. The degree of protection per EN 60529 standard is
IP 40 (device as a whole); IP51 (front, membrane keypad)
−Do not expose the device to direct sunlight.
−Please observe the permissible maximum ambient temperatures stated in
the specifications.
−The permissible relative humidity at 31 °C is 95 % (non condensing); linear
reduction to 50 % at 40 °C.
−It is safe to operate the MVD2555 system up to a height of 2000 m.
−Mounting in an EMC-tested control cabinet with line filter (see page 16).
Maintenance and cleaning
MVD2555 devices are maintenance-free. Please note the following points
when cleaning the housing:
−Withdraw the mains plug from the socket before carrying out any cleaning.
−Clean the housing with a soft, slightly damp (not wet!) cloth. You should on
no account use solvent, since it may damage the labelling on the front
panel and the indicator box.
−When cleaning, ensure that no liquid gets into the device or connections.
Residual dangers
The MVD2555’s scope of performance and supply covers part of the
measuring-technology, only. The plant designer/constructor/operator must in
addition design, realise and take responsibility for the measuring-system’s
safety such that potential residual dangers are minimized. The respective
regulations must in any case be observed. Residual dangers regarding the
measuringsystem must be specified explicitly.
Product liability

7
MVD2555
A0104−6.0 en HBM
In the following cases, the protection provided for the device may be ad
versely affected. Liability for device functionality then passes to the operator:
−The device is not used in accordance with the operating manual.
−The device is used outside the field of application described in this
Chapter.
−The 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 prop
erty.
Safety instructions are structured as follows:
SIGNAL WORD
Type of danger
Consequences of non-compliance
Averting the danger
−Warning sign: draws your attention to the danger
−Signal word: indicates the severity of the danger
(see table below)
−Type of danger: mentions the type or source of the danger
−Consequences: describes the consequences of non-compliance
−Defense: indicates how the danger can be avoided/bypassed
Danger class according to ANSI

situation in which failure to comply with safety
requirements can result in death or serious
physical injury.
This marking warns of a potentially dangerous
situation in which failure to comply with safety
requirements can result in slight or moderate
physical injury.
This marking draws your attention to a situation in

could lead to damage to property.
WARNING
CAUTION
NOTE
On the module
Meaning: Take details in the operating manual into account
On the module
Meaning: Disconnect mains supply before opening
On the module
Meaning: CE mark
The CE mark is used by the manufacturer to declare that the product com
plies with the requirements of the relevant EC directives (the Declaration of
Conformity can be found at http://www.hbm.com/HBMdoc).
On the module
Meaning : Statutory waste disposal mark
The electrical and electronic devices that bear this symbol are subject to the
European Waste Electrical and Electronic Equipment Directive 2002/96/EC.
The symbol indicates that the device must not be disposed of as household
garbage.

In accordance with national and local environmental protection and material
recovery and recycling regulations, old modules that can no longer be used
must be disposed of separately and not with normal household garbage.
If you need more information about waste disposal, please contact your local
authorities or the dealer from whom you purchased the product.
As waste disposal regulations within the EU may differ from country to coun
try, we ask that you contact your supplier as necessary.
Working safely
Note
Due to the fact that the device has not been equipped with a proper mains
switch, the supply cable must not be connected directly to the mains. VDE
guidelines require that the device can be disconnected from the mains via a
switching device (doublebreak disconnector). It is essential that the
disconnector is labeled accordingly and easy to access and operate by the
user.
The supply 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”, 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.
