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.
5
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.
MVD2555
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:
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:

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.
MVD2555
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.

D Loosen the four screws at the back of the housing.
D Carefully extract the back panel of the housing backward, with the
motherboard attached, until the jumper arrangement is accessible. You can
place a screwdriver between the connection board and the housing and
lever out the back panel.
D By following the diagram, change whichever setting is relevant to you with
the aid of the jumpers.
2.2.1 Setting the analogue output signal
To make the analogue output signal setting (voltage or current), use jumpers
ST11. Choose between "20 mA or 4 ... 20 mA in the control dialogue.
2.2.2 Choosing the operating mode for synchronization
To synchronize several devices, set one device as the Master. All the other
devices should then set to Slave. To make the ”Master” and ”Slave”
selections, use jumpers ST13, ST14 and ST15.
2.2.3 Replacing the fuses
To replace the fuse, remove the back panel of the housing as described. The
fuse (230 V/T63mA L; 115 V/T125mA L) will then be accessible on the

3.5 Synchronization
If several devices are used right next to one another or if their cables run parallel, the devices should be synchronized. To achieve this, one device is set to
Master and all the others (max. seven) to Slave. The setup with jumpers on
the amplifier motherboard is described in Chapter 2.1. As well as these settings, the devices must be linked together for synchronization.

3.6 Setting the reading angle of the display
Depending on the mounting position, it may be possible to adjust the reading
angle. A potentiometer is used for this limited adjustment. The potentiometer
is located behind the keyboard under the display. To set a new viewing angle,
proceed as follows:
D Remove the plastic frame of the display from the housing.
D Carefully lever out the keyboard (e.g. with the aid of a screwdriver).
D Use a screwdriver to turn the potentiometer and set the optimum reading
angle.
D Put back the keyboard. Make sure that the plug is correctly threaded at the
bottom edge of the keyboard. Quickly test the keyboard by pressing a key.
If it functions correctly, you can continue.
D Insert and tighten the fastening screws.
D Push the plastic frame back on the housing.
3.7 Connecting the serial interface
PK232-interface:
On the back of the device, there is anRS232 or RS485 serial
interface for connecting a computer or a terminal. The
PK485-interface is brought out at sockets Bu2 and Bu3.
When connecting a printer, a simple line printer needing no
RS485
When connecting a computer, it is possible to enter into dialogue with the
MVD2555. You can use control commands to make all the device settings and
query the measured values. An overview of the interface commands has been
compiled in another part of the Operating Manual ” Operating the MVD2555
by computer ”.
more than 4 seconds to print a line is sufficient. The printout
has 12 columns. This corresponds to a line length of 132
characters. Select the measured values to be printed as
described in Chapter 4.4.11.

4 Setting up and operation
4.1 Commissioning and factory settings
Some of the steps you need to take to commission your measurement chain
(panel-frame amplifier and transducer) are listed below, so that you can carry
out an initial function test of all components. The description basically covers
adapting the MVD2555 to the transducer type to be used. We also warn about
certain errors which can typically occur during commissioning.
D Follow the steps given in the previous chapter to connect the mains cable
and the transducer to the measuring amplifier.
Please observe the safety instructions!
D Turn on the power switch.
D The device runs a function test and is then in measuring mode. Duration
of the function test: 1.5 s (if autocalibration is enabled, approx. 2.5 s).
During the function test, the warning output stays at 0 V. The factory
settings are active.
D Check the choice of output signal shown on the display. Use
the gross signal (no labelling in the display).
NOTE
If the error message CALERR. appears here, this can have the following
causes:
- No six-wire feedback connected
- Incorrect transducer/sensor connection
to select
- No transducer/sensor connected
Remedy:
Switch off the device. Connect the transducer properly. Switch the de-
vice back on.
