Safety instructions
Use in accordance with the regulations
The MP55 module and its connected transducers are to be used exclusively
for measurement tasks and directly related control tasks. Use for any addi-
tional purpose shall be deemed to be not in accordance with the regulations.
In the interests of safety, the instrument should only be operated as described
in the User Manual. It is also essential to observe the appropriate legal and
safety regulations for the application concerned during use. The same applies
to the use of accessories.
The device must not be connected directly to the mains supply. The
maximum permissible supply voltage is 18...30 V.
General dangers of failing to follow the safety instructions
The MP55 module corresponds to the state of the art and is safe to operate.
The instrument can give rise to further dangers if it is inappropriately installed
and operated by untrained personnel.
Everyone involved with the installation, commissioning, maintenance or repair
of the instrument must have read and understood the User Manual and in par-
ticular the technical safety instructions.
Conditions on site
Protect the device from direct contact with water (IP20).
Maintenance and cleaning
The MP55 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 MP55 cover
only part of the scope of measurement technology. In addition, equipment
planners, installers and operators should plan, implement and respond to the
safety engineering considerations of measurement technology in such a way
as to minimise residual dangers. Prevailing regulations must be complied with
at all times. There must be reference to the residual dangers connected with
measurement technology.
Any risk of residual dangers when working with the MP55 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 lead to death or serious physical injury.
Symbol: CAUTION
Meaning: Possible dangerous situation
Warns of a possibly dangerous situation in which failure to comply with safety
requirements can cause damage to property or lead to some form of physical
injury.
Symbol: NOTE
Means 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 com-
plies with the requirements of the relevant EC directives (the declaration of
conformity is available at http://www.hbm.com/support/dokumentation).

Working safely
Error messages should only be acknowledged if the cause of the error is re-
moved and no further danger exists.
The instrument complies with the safety requirements of DIN EN 61010,
Part 1 (VDE 0411, Part 1).
To ensure adequate immunity from interference, use only Greenline shielded
ducting (place the shield of the transducer cable onto the connector housing).
The MP55 module must be operated with an extra-low safe voltage (supply
voltage 18 to 30 V DC).
Conversions and modifications
The MP55 module must not be modified from the design or safety engineering
point of view except with our express agreement. Any modification shall ex-
clude all liability on our part for any damage resulting therefrom.
In particular, any repair or soldering work on motherboards is prohibited.
When exchanging any modules, only original HBM parts must be used.
Qualified personnel
This instrument is only to be installed and used by qualified personnel strictly
in accordance with the technical data and with the safety rules and regulations
which follow. It is also essential to comply with the appropriate legal and
safety regulations 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 dangers involved.

1.2 Introduction
The MP55 module from the PME product line is a carrier-frequency amplifier,
and is ideal for connecting the widest possible technological varieties of force,
pressure, torque and displacement transducers as well as load cells. The
MP55 module is set up, and its parameters are assigned, using either the key-
board and display or the PME Assistent. The PME Assistent provides an easy
operator interface under MS-Windows and this is used for assigning parame-
ters to modules (as described in the ”PME Assistant” online help).

NOTE
Use standard HBM cable for the transducer connection. When using
other shielded, low-capacitance measuring cable, connect the trans-
ducer cable shielding to the connector housing in accordance with the
HBM Greenline concept (publication S1578). This ensures EMC protec-
tion.
1) For cable lengths in excess of 50 m, one resistor with half the value of the bridge resistance (RB/2) must
be switched on at the transducer in place of each of the feedback bridges. If the transducers are cali-
brated in six-core circuit, the resistors must be switched on directly in the sensor circuit.

4.4 CAN-interface
The CAN-bus is connected via terminal plug 1. A maximum of 32 CAN users
can be connected to a bus segment (in accordance with the CANopen specifi-
cation). The CAN-bus needs a terminating impedance of 120 Ω in the first and
last bus users. The bus line can have a maximum of two terminating resistors.
The MP55 module has a built-in terminating resistor which is enabled by
toggle switch S14 (see page 11).
