Safety instructions
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.
An earthed socket must be used for the mains plug (protection class I and II).
Do in no case use the device when the mains line has suffered damage.
Do in any case switch off the device before opening it; disconnect the mains
plug.
Built-in devices may only be used in the appropriate housing.
The device complies with the safety requirements of DIN EN 61010-part1
(VDE 0411-part1); protection class I.
Due to the fact that the device has not been equipped with a proper
mains switch, the connected supply cable may not be connected to
mains directly. According to a VDE recommendation these devices must
be equipped with a switching device (e.g. with a mains switch) that can
be disconnected from mains supply.
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.
Conditions on site
Protect desktop devices from moisture or atmospheric influences such as
rain, snow, etc.
Protect the device from direct sunlight.

General dangers in the case of non-observance of the safety
instructions
The MVD2555 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.
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.
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 amplifier system has been
tested.
In this manual, the following symbols are used to point out residual dangers:
Symbol: DANGER
Meaning: Maximum danger level
Warns of an imminently dangerous situation in which failure to comply with
safety requirements will result in death or serious bodily injury.
Symbol: WARNING
Meaning: Dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements can result in death or serious bodily injury.

Symbol: CAUTION
Meaning: Potentially dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements could result in damage to property or some form of
bodily injury.
Symbols pointing out notes on use and waste disposal as well as useful
information:
Symbol: NOTE
Points out that important information about the product or its handling is being
given.
Symbol:
Meaning: CE mark
The CE mark enables the manufacturer to guarantee that the product
complies with the requirements of the relevant EC directives (the declaration
of conformity is available at http://www.hbm.com/HBMdoc).
Symbol:
Meaning: Statutory marking requirements for waste disposal
National and local regulations regarding the protection of the environment and
recycling of raw materials require old equipment to be separated from regular
domestic waste for disposal.
For more detailed information on disposal, please contact the local authorities
or the dealer from whom you purchased the product.

Safe operation
Do only quit error messages if the reason for the error has been eliminated
and there is no more danger.
Reconstruction and modifications
HBM’s express consent is required for modifications regarding the MVD2555’s
construction and safety. HBM does not take responsibility for damage
resulting from unauthorized modifications.
In particular, repair and soldering works on the boards (replacement of
components except for EPROMS) are prohibited. If complete componentry is
replaced use original HBM components, only.
Qualified personnel
The device may be used by qualified personnel, only; the technical data and
the special safety regulations must in any case be observed. When using the
device, the legal and safety regulations for the respective application must
also be observed. The same applies if accessories are used.
Qualified personnel means: personnel familiar with the installation, mounting,
start-up and operation of the product, and trained according to their job.
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.

1.2 General
The panel-frame measuring amplifier MVD2555 for instrument panel
mounting (in accordance with DIN43700) is suitable for recording and
processing measured values from passive transducers in the industrial test
bench engineering sector and for monitoring production processes.
The essential features:
DTransducers that can be connected: S.G. full and half bridges, inductive full
and half bridges, piezoresistive and potentiometric transducers, LVDT
D10-digit alphanumeric display
DTouch-sensitive keypad control; individual buttons can be locked
D2 peak value stores for maximum and minimum values, as well as
envelope and instantaneous value
D4 limit switches
DRS232 or RS485 serial interface for connecting a computer or a printer
DParameter memory for saving up to 8 data sets
DControl inputs and outputs (potential-separated through optical couplers)
DThe MVD 2555-RS485 version can be operated together with other
MVD2555s (at a common RS485 bus)
All the commands needed for device setup over the serial interface and for
querying the measured values are listed and described in a separate
Operating Manual document ”Operating the MVD2555 by Computer” .
