Safety instructions
Before connecting the device, make sure that the mains voltage and current
type specified on the type plate correspond to the mains voltage and current
type at the site of installation and that the current circuit used is sufficiently
safe.
Due to the fact that the device has not been equipped with a proper
mains switch, the connected supply cable must not be directly
connected to the mains. The maximum permissible supply voltage is
18...30 V.
According to a VDE recommendation these devices must be equipped
with a switching device (e.g. with a mains switch) for disconnection
from the mains. Make sure, that the device can quickly be disconnected
from the mains at any time.
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.

6PME-MP70DP
HBM A0658−7.2 en
Appropriate use
The MP70DP module and its connected transducers may be used for mea-
surement tasks only and directly related control tasks. To ensure safe opera-
tion, the transducer may only be used as specified in the operating manual. It
is also essential to follow the respective legal and safety regulations for the
application concerned during use. The same applies to the use of accesso-
ries.
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.
General dangers due to non-observance of the safety instructions
The MP70DP module complies with the state of the art and is safe to operate.
If the equipment is used and operated inappropriately by untrained personnel,
residual dangers may arise.
Anyone responsible for installing, starting up, maintaining or repairing the
equipment needs to have read and understood the operating manual and in
particular the safety instructions.
Conditions on site
Protect the devices from moisture or atmospheric influences such as rain,
snow, etc.
Protect the device from direct sunlight. Ensure sufficient ventilation.
Maintenance and cleaning
The MP70DP module is maintenance-free. Please note the following points
when cleaning the housing:
−Before cleaning, disconnect the devices from the power supply.
−Clean the housing with a soft, slightly damp (not wet!) cloth. You should
never use solvent, since this could damage the labelling on the front panel
and the display.
−When cleaning, ensure that no liquid gets into the device or connections.

Residual dangers
The scope of supply and list of components provided with the MP70DP cover
only part of the scope of measurement technique. 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 residual dangers. Prevailing regulations must be complied with
at all times. Residual dangers connected with measurement technology need
to be pointed out.
Any risk of residual dangers when working with the MP70DP is pointed out in
this introduction by means of the following symbols:
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: Possible 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.
Symbol: NOTE
Points out that important information about the product or its handling is being
given.
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.

8PME-MP70DP
HBM A0658−7.2 en
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).
Working safely
Error messages should only be acknowledged once the cause of the error is
removed and no further danger exists.
The device complies with the safety requirements of DIN EN 61010 Part 1
(VDE 0411 Part 1).
The device must be mounted on a support rail connected to grounded
conductor potential. Both the support rail and the MP70/MP70DP module
must be free of paint, varnish and dirt at the point of installation.
To ensure adequate immunity from interference, the bus cables (CAN an for
MP70DP, Profibus DP) must be shielded, twisted−pair lines. The transducer
cables must also be shielded. To ensure adequate immunity from
interference, use Greenline shielding only (conncect the shield of the
transducer cable to the plug housing).
The cables of the digital inputs and outputs of the MP70/MP70DP should not
be longer than 30 m or should they be routed outside the building where the
system is located. Otherwise proper functioning of the device cannot be
guaranteed. The effects of strong electromagnetic fields or lightning strike
could result in damage to the instrument.
When connecting cables (fitting and extracting terminals), measures must be
taken to prevent electrostatic discharge which could damage the electronics.
The MP70/MP70DP module must be operated with a separated extra−low
voltage (18...30 V DC supply voltage), which usually supplies one or more
consumers within a control cabinet.
Should the equipment be operated on a dc voltage network1), additional
precautions must be taken to discharge excess voltages.
1) Distribution system for electrical energy with greater physical expansion (over several control cabinets, for
example) that may possibly also supply consumers with high nominal (rated) currents.

1.2 General information on MP70DP and variants
There are three different basic variants:
DMP70DP
DMP70DPS7
DMP70S7
MP70DP
The MP70DP module is a Profibus DP gateway for
measuring amplifiers of the PME family. As many as
8 measurement modules (MP01, MP30, MP55,
MP60) can be connected to the gateway.
Communication between the Profibus DP gateway
MP70DP and the modules is handled by the
integrated CAN interface. The modules are linked
together by a 10-pin ribbon cable (see Chapter 3.1
and Chapter 6). In addition to this, MP70DP has an
arithmetic function. The MP70DP forms the sum of
the gross values from a maximum of 8 input channels (measurement
modules). This value is used internally for further signal conditioning (peak
values, limit values). These variables are available both at the CAN-BUS and
the Profibus DP.

11
PME-MP70DP
HBMA0658−7.2 en
MP70DPS7
The MP70DPS7 module is an enhancement of the DP
version. An additional analogue output and four control
inputs and outputs respectively are available via
plug−in terminals.
MP70S7
The MP70S7 module corresponds to the MP70DPS7
described above, although the Profibus functions are
not available here.
Settings and parameters are assigned to the MP70DP module via the
keyboard and the display, or by using the PME Assistent. The PME Assistent
program provides a simple operator interface running under Windows for
assigning parameters to the modules (described in the ”PME Assistent” online
help).
