1. Brief description
1. Brief description
The panel meter instrument M3-11 is a 5-digit device for direct current / direct voltage signals and a visual
threshold value monitoring via the display. The configuration happens via 4 keys at the front or via the
optional PC software PM-TOOL. The integrated programming interlock prevents unrequested changes of
parameters and can be unlocked again with an individual code. Optional the following functions are
available: a supply for the sensor, a digital input for triggering of Hold (Tara), two analog outputs and
interfaces for further evaluating in the unit.
With help of the galvanic isolated setpoints (optional), free adjustable limit values can be controlled and
reported to a superior master display.
The electrical connection is done via plug-in terminals on the back side.
Selectable functions like e.g. the recall of the min/max-value, an averaging of the measuring signals, a
nominal presetting or setpoint presetting, a direct threshold value regulation during operation mode and
further measuring setpoints for linearisation, complete the modern device concept.

4. Description of function and operation
Operation
The operation is divided into three different levels.
Menu level (delivery status)
This level was designed for the standard settings of the device. Only menu items which are sufficent to set
the device into operation are displayed. To get into the professional level, run through the menu level and
parameterise prof under menu item RUN.
Menu group level (complete function volume)
Suited for complex applications as e.g. linkage of alarms, setpoint treatment, totaliser function etc. In this
level function groups which allow an extended parameterisation of the standard settings are availabe. To
leave the menu group level, run through this level and parameterise uloc under menu item RUN.
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 saved. Pressing the [O]-key leads to a break-off of the value input and
to a change into the menu level. All adjustments are saved automatically by the device and changes into
operating mode, if no further key operation is done within the next 10 seconds.

Function chart:
4.1 Parameterisation software PM-TOOL:
Part of the PM-TOOL are the software on CD and an USB-cable with device adapter. The connection
happens via a 4-pole micromatch-plug on the back side of the device, to the PC-side the connection
happens via an USB plug.
System requirements: PC incl. USB interface
Software: Windows XP, Windows VISTA
With this tool the device configuration can be generated, omitted and saved on the PC. The parameters can
be changed via the easy to handle program surface, whereat the operating mode and the possible selection
options can be preset by the program.
CAUTION!
During parameterisation with connected measuring signal, make sure that the measuring signal has no
mass supply to the programming plug. The programming adapter is galvanic not isolated and directly
connected with the PC. Via polarity of the input signal, a current can discharge via the adapter and destroy
the device as well as other connected components!

seconds and up to 10.0 seconds in increments of 1.0. With [P] the selection is confirmed and
the device changes into menu level.
Rounding of display values, round:
Default: 00001
This function is for instable display values, where the display value is changed in
increments of 1, 5, 10 or 50. This does not affect the resolution of the optional outputs. With [P]
the selection is confirmed and the device changes into menu level.

Sliding average determination, AVG:
Default: 1.0
Here, the number of the meterings that need to be averaged is preset. The time of averaging
results of the product of measuring time SEC and the averaged metering AVG. With the selection
of AVG in the menu level DISPL, the result will be shown in the display and evaluated via the
alarms.

Parameterisation level
Zero point slowdown, ZErO:
Default: 00
At the zero point slowdown, a value range around the zero point can be preset, so the display
shows a zero. If e.g. a 10 is set, the display would show a 0 in the value range from -10 to +10;
below continue with -11 and beyond with +11. The maximum adjustable range of value is 99.
Definite contstant value, const:
Default: 0
The constant value can be evaluated via the alarms or via the analog output, like the current
measurand. The decimal place cannot be changed for this value and is taken over by the
current measurand. This way, a setpoint generator can be realised via the analog output by this
value. Furthermore it can be used for calculating the difference. At this the constant value is
substracted from the current measurand and the difference is evaluated in the alerting or by the
analog output. Thus regulations can be displayed quite easily.
Minimum constant value, con.mi:
Default: -i9999
The minimum constant value is adjusted from the smallest to the highest digit with the
navigation keys [▲] [▼] and confirmed digit per digit with [P]. A minus sign can only be
adjusted on the highest digit. After the last digit the display changes back into menu level.
Maximum constant value, con.ma:
Default: 99999
The maximum constant value is adjusted from the smallest to the highest digit with the
navigation keys [▲] [▼] and confirmed digit per digit with [P]. A minus sign can only be
adjusted on the highest digit. After the last digit the display changes back into menu level.
Display, dISPL:
Default: actua
With this function the current measurand, min/max value, totaliser value or the processcontrolled Hold-value can be allocated to the display. With [P] the selection is confirmed and

Brightness control, Light:
Default: 15
The brightness of the display can be adjusted in 16 levels from 00 = very dark to 15 = very
bright via this parameter or alternatively via the navigation keys from the outside. During the
start of the device the level that is deposited under this parameter will always be used, even
though the brightness has been changed via the navigation keys in the meantime.
Display flashing, FLASH:
Default: no
A display flashing can be added as additional alarm function either to single or to a combination
of off-limit condition. With no, no flashing is allocated.
Assignment (deposit) of key functions, tASt:
Default: no
For the operation mode, special functions can be deposited on the navigation keys [▲] [▼], in
particular this function is made for devices in housing size 48x24mm which do not have a 4th
key ([O]-key). If the min/max-memory was activated by EHtr, all measured min/max-values are
saved during operation and can be recalled via the navigation keys. The values get lost by
restart of the device. If the threshold value corrections LI.12 or LI.34 were choosen, the values of
the threshold can be changed during operation without disturbing the operating procedure. With
tArA the device is tared to zero and saved permanently as offset. The device confirms the
correct taring by showing ooooo in the display. Set.tA switches into the offset value and can be
changed via the navigation keys [▲] [▼]. Via totAL the current value of the totaliser can be
displayed, after this the device changes back on the parameterised display value. If tot.rE was
deposited, the totaliser can be set back by pressing of the navigation keys [▲] [▼], the device
acknowledges this with showing ooooo in the display. The configuration of EHt.rE deletes the
min/max-memory. Under ActuA the measurand is shown, after this the display returns to the
parameterised display value. If AbS.UA (absolute value) was selected, the display shows the
value that has been measured since voltage connection, without consideration of a previous
taring. Via selection L1.1, L1.1-2, li.1-3, l1.1-4, in case of 8 switching points li.1-5…li.1-8, threshold
values can be addressed via the navigation keys; they can be changed digit per digit or taken
over by pushing the [P]-key. The adjustment is taken over directly, an excisting limit value
monitoring and the current measurement will not be influenced by this. If no is selected, the
navigation keys are without any function in the operation mode.

For the operation mode, special functions can be deposited on the [O]-key. This function is
activated by pressing the key. With tArA the device is set temporarily on a parameterised value.
The device acknowledges the correct taring with showing ooooo in the display. Set.tA adds a
defined value on to the currently displayed value. Via totAL the current value of the totaliser can
be displayed, after this the device switches back on the parameterised display value. If tot.rE
was deposited, the totaliser can be set back by pressing the navigation keys [▲] [▼], the
device acknowledges this with showing ooooo in the display. EHt.rE deletes the min/maxmemory. If HOLD has been selected, the moment can be hold constant by pressing the [O]-key
and is updated by releasing the key. Advice: Hold is activated only, if HOLD was selected under
parameter DISPL. ActuA shows the measuring value, after this the device switches back on the
parameterised display value. The same goes for AVG, here the sliding average values will be
displayed. A sensor calibration is done by triggering of the digital input via se.cal, the flow
diagram is shown in chapter 9. The constant value const can be recalled via the digital input, or
changed digit per digit. At AL-1…AL-4 an output can be set and therewith e.g. a setpoint
adjustment can be done. If no is selected, the [O]-key is without any function in the operation
mode.

Device address, ADDR:
Default: 001
The device address is adjusted from the smallest to the largest digit with the navigation keys
[▲] [▼] and confirmed digit per digit with [P]. A device address up to max. 250 is available.
Interface data: Baudrate 9600 bit/s, 8 databyte, 1 stopbit, no parity (8n1).
ModBus operating modes, b.mode:
Default: ascii
There are two different types of operating modes: ASCII and rtu. Modbus transfers no binary
cycle, but the ASCII-Code. Thus it is directly readable, however the data throughput is smaller
in comparison to the RTU. Modbus RTU (RTU = Remote Terminal Unit) transfers the data in
binary-coded. This leads to a good data troughput, even though the data cannot be evaluated
directly, as they first need to be transfered into a readable format.
Timeout, tIout:
Default: 000
The monitoring of the data transfer is parameterised in seconds up to maximum 100 seconds;
there is no monitoring with an input of 000. The timeout is adjusted from the smallest to the
largest digit with the navigation keys [▲] [▼] and confirmed digit per digit with [P]. After the

Operating current / Quiescent current
Operating current
By operating current the alarm S1-S4 is off
below the threshold and on on reaching the
threshold.
Quiescent current
By quiescent current the alarm S1-S4 is on
below the threshold and switched off on
reaching the threshold.
Switching-on delay
The switching-on delay is activated via an
alarm and e.g. switched 10 seconds after
reaching the switching threshold, a shortterm exceedance of the switching value does
not cause an alarm, respectively does not
cause a switching operation of the relay. The
switching-off delay operates in the same way,
keeps the alarm / the relay switched longer
for the parameterised time.

8. Interfaces RS232 and RS485
The interface RS485 is connected via a screened data line with twisted wires (Twisted-Pair). On each end
of the bus segment a termination of the bus lines needs to be connected. This is neccessary to ensure a
secure data transfer to the bus. For this a resistance (120 Ohm) is interposed between the lines Data B (+)
and Data A (–).

9. Sensor alignment offset / final value
9. Sensor alignment offset / final value
The device is equipped with a semi-automatic sensor calibration (SENSu / SENSa). A switching output
operates the trimming resistor, which exists in some sensors. An adjustment of offset and final value takes
place, after which the sensor can be used directly. Depending on parameterisation, the calibration can be
realized via the 4th key or via the digital input. It is possible to key during the calibration steps. So, reference
signals can be connected manually. However the calibration will be interrupted after 30 seconds.

11. Safety advices
11. Safety advices
Please read the following safety advices and the assembly chapter 2 before installation and keep
it for future reference.
Proper use
The M3-11-device is designed for the evaluation and display of sensor signals.
Danger!
Careless use or improper operation can result in
personal injury and/or cause 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 M3-11-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 the 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 isolated potentials within one complex need to be placed on an 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.
