The MP85/MP85DP module and its connected transducers are to be used
exclusively for measurement tasks and directly related control tasks. Use for
any purpose other than the above shall be deemed to be not in accordance
with the regulations.
To ensure safe operation, the device may only be operated in accordance with
the information given in the Operating 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.
The device must not be connected directly to the mains supply. The
supply voltage may be 18 to 30 V.
General dangers of failing to follow the safety instructions
The MP85/MP85DP module corresponds to the state of the art and is
fail−safe. The device may give rise to further dangers if it is inappropriately
installed and operated by untrained personnel.
Any person instructed to carry out installation, commissioning, maintenance or
repair of the device must have read and understood the Operating Manual
and in particular the technical safety instructions.

Working safely
Error messages must only be acknowledged when the cause of the error has
been removed and no further danger exists.
The instrument complies with the safety requirements of DIN EN 61010, Part
1 (VDE 0411, Part 1) protection class I.
The device must be mounted on a supporting rail connected to the protective
earth potential. Make sure, that at this spot both the supporting rail and the
MP85/MP85DP module are free from dirt and other foreign material.
To guarantee adequate immunity from interference, the buses (CAN and in
the case of MP85DP, Profibus DP) should be run with shielded and twisted
2-wire lines. The transducer lines should also be run using shielded cables.
A0897−3.4 enHBM
Page 7
PME-MP85
The shield of each transducer cable should be connected at the PME end by
as short a line as possible (t5 cm) and a blade connector (4.8 mm;
“Faston”).
The lines to connect the power supply and the digital control inputs and
outputs only need to be shielded if the cable length exceeds 30 m or if the
lines are installed outside closed buildings.
When connecting the lines (clip on and pull off clamps) and when replacing
the MMC, measures must be taken against electrostatic discharge to prevent
damage to the electronics.
The MP85/MP85DP module should be operated at a separated extra−low
voltage (SELV) (supply voltage 18 − 30 V DC) that usually supplies one or
more consumers within a control panel.
1)
If the device is operated on a direct voltage network
, additional precautions
must be taken to discharge excess voltages.

The MP85/MP85DP module must not be modified from the design or safety
engineering point of view except with our express agreement. Any
modification shall exclude all liability on our part for any resulting damage.
In particular, any repair or soldering work on motherboards is prohibited.
When exchanging complete modules, use only original parts from HBM.
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 legal and safety
requirements for the application concerned during use. The same applies to
the use of accessories.

The PME Assistant provides a simple user interface under MS-Windows for
parameterizing the modules.
The PME Assistant is the sole means of parameterizing and setting up
the MP85/MP85DP module (described in the Online Help).
To do this you need an LPT → CAN or USB → CAN interface converter, that
has to be ordered separately (1−PMESETUP; 1−PMESETUP-USB).
The software allows you to set all the device parameters apart from the one
for the CAN-BUS interface used for setup.
The software also allows you to set up the other devices of the PME family.

Fig. 5.4:Transducer connection in four-wire technology
NOTE
To connect the transducers, use standard cable from HBM or another
shielded, low-capacitance measurement cable. Connect the shield of
each transducer cable via the shortest possible lead (t5 cm) and a
blade connector (4.8 mm; “Faston”) to the right of screw terminal 6. This
ensures EMC protection.
1)
For cable lengths >50 m, instead of feedback bridges, a resistance with half the value of the bridge
resistance (RB/2) must be activated at the transducer. If the transducers are calibrated in a six-wire circuit,
the resistances must be activated directly into the sensor circuit.

Synchronization:
Synchronization is advisable for carrier-frequency fed transducers if
D the transducer cables of several devices are installed side by side
D the measuring points are close together and unshielded
Synchronisation prevents carrier frequency differences leading to disturbing
superpositions.
PME-MP85
When synchronizing several modules, one device has to be declared the
master. The remaining devices must be set to slave (use Setup).
Synchronization between modules should always − even if you are working
without a CAN bus − be effected with the ribbon cable.

PME-MP85
A supply voltage is available at screw terminals 5 and 6, pins 7 and 8 for
feeding incremental transducers and transducers with an SSI interface.
Switch S1 is used to toggle between an internal and an external supply. The
device has to be opened to do this. (see Chapter 3).
•Transducer supplied from the MP85/MP85DP:
Transducer supply voltage 5V "10 %, 150 mA max. (for both channels
together). The supply is then not electrically isolated from the
measurement system.
•Transducer supplied from an external power pack:
At screw terminal 3, pins 5 and 6, a voltage between 10 − 30 V
24 V
) including ground is applied. A current of max. 300 mA (for both
DC
(nominal
DC
channels together) can then be drawn at transducer terminals 5 and 6.
This external supply voltage is electrically separated from the signal ground
and at the same time feeds the digital control outputs.

5.5CAN interface
The CAN bus is connected via screw terminal 1. A maximum of 32 CAN
nodes can be connected in one bus segment (under CANopen specification).
The CAN bus needs a terminating resistance of 120 Ω in the first and last bus
nodes. The bus line must have no more than two terminating resistances. A
terminating resistance is integrated in the MP85DP module and is activated
by toggle switch S2.

Installation:
•Connect the MP85DP module to the 24 V supply voltage and set the
required Profibus address via the keyboard or the Setup program.
•Connect the Profibus cable to the MP85DP module. Ensure that a
terminating resistance is connected to the first and last Profibus unit (the
housing of the Profibus connector usually contains a sliding switch for this
purpose).

All the diagrams relate to a positive logic.
6.1Timing of the test operations
a.) Storing curves and results without data loss
The below diagrams apply, if you choose the “without data loss” storage method and want to save curves and/or results on the MMC or externally via
CAN. The READY signal is not reset to 1 until the device is ready to save data
for the next process.
NOTE
Before starting a new measurement, the READY bit must have been reset to 1.

PME-MP85
b.) Process optimized storage of curves and results
The below diagrams apply, if you choose the “Process optimized storage” storage method and want to save curves and/or results on the MMC or externally
via CAN. In contrast to the “Storing without data loss” method, the READY signal can be reset to 1 even if the device is not yet ready to save new data.
Consequently the results and curve files might not be transmittes if you start a
new measurement immediately. This method should only be chosen if extremely fast processes must be monitored and the results and curves are merely
used for random sample checks.
NOTE
Before starting a new measurement, the READY bit must have been reset to 1.
