Safety instructions
Appropriate use
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.
Conditions on site
Protect the device from direct contact with water (IP20).
Maintenance and cleaning
The MP85/MP85DP 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.
Remaining dangers
The scope of supply and list of components provided with the MP85/MP85DP
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 considerationsof measurement technology
in such a way as to minimize remaining dangers. Prevailing regulations must
be complied with at all times. There must be reference to the remaining
dangers connected with measurement technology.

Any risk of residual dangers when working with the MP85/MP85DP is pointed
out in this introduction by means of the following symbols:
PME-MP85
Symbol:
Meaning: Dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements can result in death or serious physical injury.
Symbol:
Meaning: Potentially 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
physical injury.
Symbols indicating application notes and useful information:
Symbol:
WARNING
CAUTION
NOTE
Indicates that important information is given about the product or how to
handle it.
Symbol:
Meaning: CE mark
With the CE mark, the manufacturer guarantees that his product complies
with the requirements of the relevant EC guidelines (see Declaration of
conformity at the end of this operating manual).
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
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.
7
Conversions and modifications
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.
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 danger involved.

Distribution system for electrical power with greater spatial expansion (e.g. via several control panels) that
may possibly even supply consumers with high nominal (rated) currents.

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.

Then the MMC can be removed.
Storing Data is written to the MMC. Upon completion of data sto-
rage, the state changes to “Ready”; SET ³ STOP is displayed.
Stopped Before removing the MMC from the device,
you must press the SET key to close all files
and write the FAT.

The message “MMC Disk Closed” or in case of an error
“MMC DiskClose Err” is displayed for a short time.
Then the MMC changes to the “Stopped” state and can be
removed from the device.
If there is no more free memory available on the MMC, the
status automatically changes to “Stopped”.
The only way to exit this state is to remove the MMC from
the device. Afterwards, there will be an automatic reinitialization.
5. Error types

2.2 Configuring the hardware
2.2.1 Voltage supply / Transducer
• Connect the power supply cable and the transducer to the module
(Chapters 5.3 and 5.4).
CAUTION
Be sure to comply with the safety instructions!
• Activate the power supply.
• The device will run a self-test (approx. 10 secs) and will then, if working
properly, be in measuring mode. During the self-test, the control
outputs stay at 0V.
If ! appears in the display or the status LED shows red, please consult
Chapter 7 ”Error messages”.
• Connecting the bus system
To find out how to connect several devices to a CAN bus, refer to Chapter 5.5.
How to set up the CAN address and the baud rate is described in Chapter
2.1.3.
NOTE

2.2.2 Connecting the CAN adapter (LPT and USB)
To enable PME devices to communicate with the PC, you first have to link the
device to the PC.
1. Connecting LPT to CAN (parallel interface)
• Switch off the PC and attach the LPT to CAN adapter to the parallel
interface port of the PC.
Unfortunately it is not possible to operate a printer from this parallel
interface at the same time. You need a second parallel interface.
• Attach the cable on the adapter between the male connector of the PS2
mouse and the female connector of the PC. This cable is needed to supply
power for the adapter. Alternatively you can attach this power supply cable
between the keyboard connector and the relevant PC socket.
• Attach the CAN connector cable to the MP85 to the adapter.
• Activate the PC.
2. Connecting USB to CAN
First install the PME Assistant.
• Attach the USB to CAN adapter to a free USB interface on your PC.
• The PC will immediately detect the adapter (Plug and Play).
A floppy disk is supplied with the adapter. It includes the driver required for
installation.
