1 Safety instructions
Appropriate use
The PMX amplifier system is to be used exclusively for
measurement tasks and directly related control tasks.
Use for any purpose other than the above is deemed to
be non-designated use. In the interests of safety, the
device should only be operated as described in the
Operating Manuals. 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.
Safety instructions
This can be done, for example, by mechanical
interlocking, error signaling, limit value switches, etc.
Notice
The device must not be directly connected to the DC
voltage supply system. Supply voltage 10 V … 30 V
(DC).
Before commissioning, ensure that a suitable supply
voltage is used and that the circuit used is sufficiently
protected.
PMX A4354-2.2 HBM: public 13
Page 14
Safety instructions
The device may only be supplied with separated extralow voltage (safety isolating transformer according to DIN
VDE 0551 / EN60742). Only operate built-in devices once
they are installed in the housing provided. The device
development is based on DIN EN 61010 Part 1 (VDE
0411 Part 1).
General dangers of failing to follow the safety
instructions
The PMX system is a state of the art unit and as such is
reliable. The module may give rise to dangers if it is
inappropriately installed and operated by untrained
personnel.
Any person instructed to carry out installation, starting up,
maintenance or repair of the module must have read and
understood the Operating Manual and in particular the
technical safety instructions.
Conditions at the place of installation
S Protect the device from direct contact with water.
S Protect the PMX system from moisture and humidity
or weather conditions such as rain, snow, etc.
S Do not expose the device to direct sunlight.
S Please observe the permissible maximum ambient
temperatures stated in the specifications.
S The permissible relative humidity at 31 °C is 95 %
(non condensing); linear reduction to 50 % at 40 °C.
S Install the device so that it can be disconnected from
the supply voltage at any time without difficulty.
S It is safe to operate the PMX system up to a height of
2000 m.
14 A4354-2.2 HBM: public PMX
Page 15
Safety instructions
Maintenance and cleaning
The PMX system is maintenance-free.
S Before cleaning, disconnect all connections.
S Clean the housing with a soft, slightly damp (not wet!)
cloth. You should never use solvents, since these
could damage the labeling.
S When cleaning, ensure that no liquid gets into the
module or connections.
Residual dangers
The scope of supply and performance of the PMX system
only covers a small area 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 minimize remaining dangers. On-site
regulations must be complied with at all times. There
must be reference to the remaining dangers connected
with measurement technology.
Product liability
In the following cases, the protection provided for the
device may be adversely affected. Liability for device
functionality then passes to the operator:
S The device is not used in accordance with the
operating manual.
S The device is used outside the field of application
described in this Chapter.
S The operator makes unauthorized changes to the
device.

By buying the PMX measuring amplifier system, you
have chosen a high-quality HBM measurement system
that is compact, powerful and variable. The data rate for
all the measurement and calculation channels is 19,200 /
38,400 measurements per second. The device thus
achieves an overall processing rate of approx. 400,000
measured values per second.
Numerous different measurement, control and
automation tasks can be resolved with this measurement
system.
Connection to a PC (HOST)
The PMX measuring amplifier system is connected to a
PC via the standard ETHERNET interface, and can be
parameterized and operated via the internal web server.
The link to an automation system can be connected via
digital and analog inputs/outputs, as well as over the
fieldbus interfaces of the PMX, to a control (PLC) or a
primary automation system.
Internal calculation channels
The PMX has 32 internal calculation channels as
standard, which are freely available for evaluations and
mathematical measurement signal calculations.
Automation tasks from peak values to PID controllers can
be implemented simply and elegantly.

Connection technique
Transducers are connected to the amplifiers via plug
terminals.
Plug terminals using push-in technology are available as
standard, with a screw-on system also available as an
option. If required, both types can be coded with the
enclosed coding pins to prevent mix-ups.
TEDS (Plug&Measure)
PMX amplifiers support TEDS (Transducer Electronic
Data Sheet, IEEE1451.4). When transducers are
connected, they are automatically detected. This
efficiently minimizes setup times and user error.
PMX web server
An easy to operate web server that is specifically tailored
to the PMX and is suitable for the measurement cards, is
integrated into the device for configuration, data
acquisition and visualization.
This gets you quickly to your measurement result, where
you can visualize the measured data and view them at a
later date.
PC software catman®EASY/AP
The HBM catman® software can be used to acquire,
condition and analyze the PMX measurement data, as an
option. This allows vast quantities of measurement data
to be displayed (stripchart function), analyzed and
exported in the most commonly used formats.

8.4 Measurement cards / transducer
8.4.1 Intrinsically safe measurement circuits -
To operate transducers (load cells, force transducers,
etc.) in potentially explosive atmospheres, intrinsically
safe measurement circuits (Ex II (1) GD, [EEx ia]IIC)
must be set up on the PX455 by connecting safety
barriers (Zener barriers) type SD01A. The safety barriers
must also be mounted on the DIN rail like the PMX. An
ATEX test certificate must be available for the
transducers used. Transducers with 350 ohm bridge
resistance can be used. One transducer per
measurement channel of the PC455 can be operated
(parallel connection is not possible).
The PX455 offers 4 measurement channels with 4.8kHz
carrier frequency measurement. If the measurement
signals need to be added/subtracted or mean values
formed, this can be set using the internal PMX calculation
channels.
connection
Operation with Zener barriers
Important
In addition to the SD01A, the negative operating voltage
of the PMX must be grounded!
Cable lengths of up to max. 100 m are permissible. TEDS
cannot be used.
The measurement accuracy of the PX455 with operation
of the SD01A is max. 0.5%.

Transducer connection in a four/three wire
configuration:
When connecting a transducer in a four/three wire
configuration, the sense leads must be connected to the
corresponding bridge excitation circuit (PIN 2'-2 and
Pin 3'-3) by wire bridges, as otherwise a sensor error will
be detected.
TEDS functionality is not available when connecting in a
fourwire configuration.

8.4.2.5 PX455 with Pt100 temperature measurement
With the PX455 measurement module, temperatures can
be measured with an uncertainty of +/-1°C without an
external preamplifier. A 100 ohm precision resistor
(R_comp) with a maximum tolerance of 0.1% is added to
a Pt100 resistor to make a half bridge circuit. The PMX
calculated channel "Pt100 on PX455" converts the meas
ured bridge unbalance to degrees Celsius and performs a
corrective calculation appropriate to the sensor cable be
ing used (R_wire).
Good heat dissipation is essential to keep the measure
ment error caused by the self heating of the Pt100 as low
as possible! This can be done, for example, by mounting
it on a metallic body.

8.4.3.5 PX401 with charge amplifier
Piezoelectric sensors can be operated with the PX401 via
external CMA or CMD charge amplifiers. The charge
amplifiers convert the sensor signal into a +/-10 V voltage
signal. The reset/operate charge amplifier signal can take
place in the PMX from an external controller or via a
PX878 digital output. The CMA charge amplifier can be
supplied directly by the PX401 measurement module.
Important
Due to the inrush current of the CMD charge amplifier,
the current feed of the CMD must be separate and not via
the PX401 measurement module.
