2. Electrical connectio
Connection example:
Profibus arranges the devices in sequence. An allocation in form of a star is not acceptable! Both ends of the
data line require a termination. One in the triggering included termination needs to be activated. The maximum
allowable length of the data line depends on the baudrate an is 1000 m.
For simplification of the electrical connection, the terminals are carried out doubly. At the last device of tha
bus-line, the termination can be switched onto the bus-line with two bridges.

3. Function and operation description
Operation
The device is triggered via Profibus and shows numerics and signs in a 6-digit 7-segment
display.
Thereby the communication can be triggered via a Bus master. The display recognizes
automatically the used Baudrate with a Bus master and needs as single information the
Profibus address, which can be parametrised via the keypad of the display.
Parameterisation level:
Parameter deposited in the menu item can here be parameterised.
Functions, that can be changed or adjusted, are always signalised by a flashing of the
display. Settings that are made in the parameterisation level are confirmed with [P] and thus
safed. By pressing the [O]-key (zero-key) it leads to a break-off of the value input and to a
change into the menu level.
All adjustments are safed automatically by the device and it changes into operating mode, if
no further key operation is done within the next 10 seconds.

4. Setting up the device
Adjusting the brightness brt:
With this parameter the brightness of the display can be reduced onto 25% of the total
brilliancy. With [P] the selection is confirmed and the device switches back into menu
level.
Setting the decimal point, dot:
The decimal point on the display can be moved with [▲] [▼] and confirmed with [P].
The display then switches back to the menu level again.
Selection of the device address Adr:
Device addresses from 1-125 can be parametrised. The address 126 is preset as
default value, which is the delivery state. After changing this parameter, the device
does a soft test bevor switching back into operation mode. After this, the new address
will be directly in use.
Parameterisation levelMenu level
4.1. Switching-on
Once the installation is complete, you can start the device by applying the voltage supply.
Before, check once again that all electrical connections are correct.
Starting sequence
For 1 second during the switching-on process, the segment test (8 8 8 8 8) is displayed
followed by an indication of the software type and, after that, also for 1 second the software
version. After the starting sequence, the device switches to operation/display mode.
4.2. Standard parameterisation: (Flat operation level)
To parameterize the display, press the [P] key in operating mode for 1 second. The display
then changes to the menu level with the first menu item TYPE.
4. Setting up the device

4. Setting up the device
Administrator code / Master code (4-digit number-combination free available),
A.Co:
With this code all parameters can be re-activated, after LOC has been activated under
menu item run before. By pushing [P] in operation mode for approx. 3 seconds, CodE
occurs in the display and enables the user to reach all parameters by entering the
A.co. While leaving the parameterisation under run, the parameterisation can be
activated permanently by selection of ULC. So that at a renew pushing of [P] in
operating mode, no new entering of the code needs to be done.
Activiation / Deactivation of the programming interlock or closing-off of the
parametrisation, run:
With the navigation keys [▲] [▼], one can choose between the deactivated key lock
Uloc (works setting) and the activated key lock Loc. Confirm the selection with [P].
After this, the display confirms the settings with "-----", and automatically switches to
operating mode. If Loc was selected, the keyboard is locked. To get back into the
menu level, press [P] for 3 seconds in operating mode. Now enter the CODE (works
setting 1 2 3 4) that appears using [▲] [▼] plus [P] to unlock the keyboard. FAIL
appears if the input is wrong. By pressing [P] in operation mode for approx. 3
seconds, the first menu group adr appears in the display and thus confirms the
change into parameterisation. It stays activated as long as ULOC is entered in menu
group RUN, thus the display is set back in standard parameterisation again.

6. Error indications
6. Error indications
The display controls several possibilites of errors and shows them if required in the display.
Overflow behavior
If a process value (Integer value) is transfered, that exceeds the display range of the
display, then the display shows a fast flashing display with the incorrect value, this means
the available significant digits. The minus sign needs its own digit. The same happens in
operation type 5, if segments are triggered, that are not available in the display. In this case
the defined display segments are flashing with a high frequency.
Error indications
During the starting sequence a check of the configuration is done. Furthermore an error
number / warning number can be found in the Gateway. It then alerts a checksum error, an
EEPROM error or a Profibus error.
After this the device processor starts with the cyclic scanning of the display segments that
need to be displayed, which state the operating mode.
Watchdog in Gateway is invalid„Er8“Watchdog overflow
Gateway works in an inoperative operating type„Er7“Configuration error
Profibus master offline„Er6“Data exchange error
Gateway receives too many data„Er5“DATA overflow
Gateway checksum of a parameter is faulty„Er4“PCHECKSUM error
Gateway Profibus error„Er3“SPC3 error
Communikation error with EEPROM„Er2“EEPROM error
Gateway does not answer„Er1“Gateway error
Parameter in device processor is not consistent„HLP“Checksum error
DescriptionMessageSource of error
If an initialisation error occurs, the error indications appers directly in the display. At an
operating error the display reacts with fast flashing of the current dates for at least 10
seconds.
Occured errors can be called up by shortly pushing the [▲] or [▼] key. The single errors
can be called up by pushing the keys shortly several times. Each single error can be
deleted by pushing the [▲] or [▼] key for approx. 1 second.
If no error did occur then „noE“ appears. After the error indication the display changes back
automatically into operting mode after approx. 7 seconds.

9. Safety advice
Please read the following safety advice and the assembly chapter 1 before installation
and keep it for future reference.
Proper use
The M2-device is designed for the evaluation and display of sensor signals.
Danger! Careless use or improper operation can result in
personal injury and/or damage to the equipment.
Control of the device
The panel meters are checked before dispatch and sent out in perfect condition. Should
there be any visible damage, we recommend close examination of the packaging. Please
inform the supplier immediately of any damage.
Installation
The M2-device must be installed by a suitably qualified specialist (e.g. with a
qualification in industrial electronics).
Notes on installation
• There must be no magnetic or electric fields in the vicinity of the device, e.g. due to
transformers, mobile phones or electrostatic discharge.
• The fuse rating of the supply voltage should not exceed a value of 6A N.B. fuse.
• Do not install inductive consumers (relays, solenoid valves etc.) near the device and
suppress any interference with the aid of RC spark extinguishing combinations or free-
wheeling diodes.
• Keep input, output and supply lines separate from one another and do not lay them
parallel with each other. Position “go” and “return lines” next to one another. Where
possible use twisted pair. So, you receive best measuring results.
• Screen off and twist sensor lines. Do not lay current-carrying lines in the vicinity. Connect
the screening on one side on a suitable potential equaliser (normally signal ground).
• The device is not suitable for installation in areas where there is a risk of explosion.
• Any electrical connection deviating from the connection diagram can endanger human life
and/or can destroy the equipment.
• The terminal area of the devices is part of the service. Here electrostatic discharge needs
to be avoided. Attention! High voltages can cause dangerous body currents.
• Galvanic insulated potentials within one complex need to be placed on a appropriate point
(normally earth or machines ground). So, a lower disturbance sensibility against impacted
energy can be reached and dangerous potentials, that can occur on long lines or due to
faulty wiring, can be avoided.
