DT85
Safety information
Appropriate use
The DT85 with its connected amplifiers must only be used for measurement
tasks and directly associated control tasks. Use for any purpose other than
the above shall be deemed to be inappropriate.
In the interests of safety, the device should only be operated as described in
the Operating 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.
General dangers of failing to follow the safety instructions
The DT85 is a state of the art unit and as such 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 (IP52 at the front, IP20 at the
back).
Maintenance and cleaning
The DT85 is maintenance-free. Please note the following points when
cleaning the housing:
- Before cleaning, disconnect the device 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 labeling on the front panel
and the display itself.
- When cleaning, ensure that no liquid gets into the device or the
connections.
Remaining dangers
The scope of supply and performance of the DT85 covers only 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. Prevailing regulations must be complied with at all times.
There must be reference to the remaining dangers connected with
measurement technology.

DT85
Any risk of remaining dangers when working with the DT85 is pointed out in
these instructions by means of the following symbols:
5
Symbol:
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:
Meaning: Potentially dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements could lead to damage to property and slight or moderate
physical injury.
Symbols for operating instructions and useful information:
Symbol:
WARNING
CAUTION
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
complies with the requirements of the relevant EC directives (see Declaration
of Conformity at http://www.hbm.com/support/dokumentation).
Working safely
Error messages must only be acknowledged once the cause of the error has
been eliminated and the danger no longer exists.
The device complies with the safety requirements of DIN EN 61010 Part 1
(VDE 0411 Part 1); protection class I.
HBMA1704-1.1 en

DT85
To ensure adequate immunity from interference, the bus lines must be
shielded cables.
The power supply connection cables only need to be shielded if the cables
are longer than 30 m or are routed outside closed buildings.
When connecting the cables (attaching and detaching terminals), action must
be taken to prevent electrostatic discharge which could damage the
electronics.
The DT85 must be operated on a safety extra-low voltage (supply voltage
18...30 V DC), which usually supplies power to one or more consumers within
a control cabinet.
1)
Should the device be operated on a dc voltage network
, additional
precautions must be taken to discharge excess voltages.
Conversions and modifications
The DT85 display 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 damage resulting there from. In
particular, any repair or soldering work on motherboards is prohibited. When
exchanging complete modules, use only original parts from HBM.
Qualified personnel
This device 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 observe 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)
Distribution system for electrical energy with greater spatial expansion (e.g. over a number of control
cabinets) that may even supply consumers with large nominal currents.

2 Application notes
The DT85 is an add-on for the twin-channel MP85 and MP85DP amplifiers of
the PME product family.
Most important applications of the DT85:
• Graphical representation of all measured values, evaluation windows and
press-fit curves with OK / NOK decision-making
• Displaying status information
• Viewing all the important MP85 settings
• Loading and storing parameter sets in/from flash or MMC memory
• Setting the most important parameters (e.g. tolerance windows) and
functions (sensor test)
• The DT85 is not suitable as a display for tolerance band mode, as an
evaluation criterion
NOTE
Measurement acquisition, analysis and curves/results storage
take place in the connected PME device. The DT85 serves as
a display and control unit.

3 Connecting the DT85
Information is exchanged between the DT85 and the MP85(DP) modules via
the CAN bus.
Up to 10 MP85 modules can be connected and parameterized. The DT85 can
be supplied with voltage via the screw terminal of the MP85 module.
Low High
0V
+UB
X 2
Voltage supply and
CAN
CAN gateway
X 2
. . . . .max. 10
active
X 3
There are two possible applications:
• Connecting the DT85 display via the CAN bus on the MP85(DP) module
• Linking the PC with the DT85 via the second CAN interface (if necessary,
use a dongle at the PC, CAN-USB)
As soon as the PC is connected and the PME Assistant has been started up,
the display is muted and works as a gateway between the MP85 and the PC.
After closing the PME Assistant, the DT85 can be re-activated by the “DT85”
function.
NOTE
The DT85 can be both connected to the MP85(DP) module and
disconnected from the MP85(DP) module while measuring
mode is running, without detriment. This also applies to
connecting a PC to the PME Assistant.

Use the ZOOM function to scale the graphic window (magnifying glass
function). In the factory setting, the display detail corresponds to the set range
window. The ZOOM range can be moved to any of the four pages.
Use the PREVIOUS key to transfer the set ZOOM range to the graphic
window, which also sets it up for all further measurements. The ZOOM Off key
resets the screen detail back to the size of the range window.
To zoom the window, you must first use the keys to select the required page,
for example, X1. You can then use the ENTER key (rotary knob) to modify the
view. Should further changes be necessary, you can now select and modify
the next page.

- The other PME modules are
displayed and selected via the
Scan function.
- Status display of the digital
inputs/outputs (1=active / 0 =
inactive).
- Status display of the entire process
and of the possible alarm cause.

- Graphical representation of the
entire process with results display
and status messages.
- In a case of NOK, the screen is
switched to inverse, to make the
NOK processes easier to recognize.
- The upper X axis is used to display
the coordinates for relative
(dynamic) windows.
See Section 4.5 for a description of the
ZOOM function

- Detailed result display for each
tolerance window and of the overall
result.
This allows conclusions to be drawn
about the course and the status of
the production process.
- Exact statistics for each tolerance
window.
Statistics can be called up for each
parameter set (Use PS+ and PS- to
select the next or the previous
parameter set). PS = parameter set

Flash error An error occurred when reading out
the Flash EOROM.
This can be a one-off read error,
please repeat the operation. If
the error occurs again, please
contact HBM Service.
For more details, please refer to the MP85 online help and operating manual.
If CAN bus communication between DT85 and MP85 does not work
properly, the below message is displayed:
The MP85 still remains operative and will not be affected.
If the interruption has been only temporary, press the ENTER key
or F1
for acknowledgement. Otherwise, the wiring has to be checked or the devices
must be restarted.
