1. Brief description
The panel meter instrument M3-36 is a 5-digit device for resistance values up to 100 kΩ and a visual
threshold value monitoring via the display. The configuration happens via 3 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 available are one analog output or
interfaces for further evaluating in the unit.
With help of the two galvanic isolated switching points (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 value setting or setpoint setting, a direct threshold value regulation during operation mode and
additional measuring supporting points for linearisation complete the modern device concept.

4. Function description 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 that are 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 is
done via a 4-pole micromatch-plug on the back side of the device, to the PC-side the connection ist done 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 safed 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!

available. Confirm the selection with [P]. The display then switches back to the menu level
again.
Setting the end value of the measuring range, END:
Default: 10000
Set the end value from the smallest to the highest digit with [▲] [▼] and confirm each digit with
[P]. A minus sign can only be parameterized on the highest value digit. After the last digit, the
display switches back to the menu level. If Sr.xxx was selected as input option, you can only
select between noca and cal. With noca, only the previously set display value is taken over, and
with cal, the device takes over both the display value and the analogue input value.
Setting the start/offset value of the measuring range, offs:
Default: 0
Enter the start/offset value from the smallest to the highest digit with [▲] [▼] and confirm each
digit with [P]. After the last digit the display switches back to the menu level. If Sens was
selected as input option, you can only select between noca and cal. With noca, only the
previously set display value is taken over, and with cal, the device takes over both the display
value and the analogue input value.
Setting the decimal point, dot:

The display then switches back to the menu level again.
Selection of analog output, Out.rA:
Default: 4-20
Three output signals are available: 0-10 VDC, 0-20 mA and 4-20 mA, with this function, the
demanded signal is selected.
Setting up the final value of the analog output, Out.En:
Default: 10000
The final value is adjusted from the smallest digit to the highest digit with [▲] [▼] and digit by
digit confirmed with [P]. A minus sign can only be parameterised on the highest digit. After the
last digit, the device changes back into menu level.
Setting up the initial value of the analog output, Out.OF:
Default: 00000
The final value is adjusted from the smallest digit to the highest digit with [▲] [▼] and digit by
digit confirmed with [P]. A minus sign can only be parameterised on the highest digit. After the
last digit, the device changes back into menu level.
Threshold values / limits, LI-1:
Default: 2000
This value defines the threshold, that activates/deactivates an alarm.
Hysteresis for limit values, HY-1:
Default: 00000
The delayed reaction of the alarm is the difference to the threshold value, which is defined by
the hysteresis.

5. Setting up the device
Menu level
Parameterisation level
Function for threshold value undercut / exceedance, Fu-1:
Default: high
A limit value undercut is selected with Louu (for LOW = lower limit value), a limit value
exceedance with High (for HIGH = higher limit value). If e.g. limit value 1 is on a threshold level
of 100 and allocated with function High, an alarm is activated by reaching of the threshold level.
If the threshold value was allocated to Low, an alarm will be activated by undercutting the
threshold value, as long as the hysteresis is zero.
The same applies to Li-1 to LI-2 !
User code (4-digit number-combination, free available), U.CodE:
Default: 0000
If this code was set (>0000), all parameters are locked for the user, if LOC has been selected
before under menu item run. By pressing [P] for 3 seconds in operation mode, the display
shows COde. The U.Code needs to be entered to get to the reduced number of parameter sets.
The code has to be entered befor each parametrisation, until the A.Code (Master code) unlocks
all parameters again.
Master code (4-digit number-combination, free available), A.CodE:
Default: 1234
All parameters can be unlocked with this code, after LOC has been activated under menu item
run. By pressing [P] for 3 seconds in operation mode, the display shows COde and enables the
user to reach all parameters by entering the A.codE. Under run the parameterisation can be
activated permanently by selecting ULOC or ProF, thus at an anew pushing of [P] in operation
mode, the code needs not to be entered again.
5.3. Programming interlock „RUN“
Activation / deactivation of the programming lock or completion of the standard
parameterisation with change into menu group level (complete function range), run:
Default: uloc
With the navigation keys [▲] [▼], choose between the deactivated key lock Uloc (works
setting) and the activated key lock Loc, or the change into the menu group level ProF. 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. To parameterise further functions ProF needs to be set. The device confirms this
setting with „- - - - -„ and changes automatically in operation mode. By pressing [P] for approx.
3 seconds in operation mode, the first menu group InP is shown in the display and thus confirms
the change into the extended parameterisation. It stays activated as long as ULOC or LOC is

Number of additional supporting points, SPCt:
Default: 00
30 additional supporting points can be defined to the initial value and final value, so linear
sensor values are not linearised. Only activated setpoint parameters are displayed.
Display values for supporting points, dIS.01 … dIS.30:
Under this parameter supporting points are defined according to their value. At the sensor
calibration, like at final value/offset, one is asked at the end if a calibration shall be activated.
Analog values for supporting points, InP.01 … InP.30:
The supporting points are always preset according to the selected input signal mA/V. The
demanded analog values can be freely adjusted in ascending order.

Display time, DISEC:
Default: 01.0
then
The display time is set up with [▲] [▼]. Thereby you switch up to 1 second in steps of 0.1 and
up to 10.0 seconds in steps 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 incements 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.
Arithmetics, ArItH:
Default: no
Reciprocal
Root extraction
Square
With this function the calculated value, not the measuring value, is shown in the display. With
no, no calculation is deposited. With [P] the selection is confirmed and the device changes into
menu level.
Sliding average determination, AVG:
Default: 10
Under this menu item, the number of measurements that need to be averaged are preset. The
averaging time results from the product of measuring time SEC and the averaged measurements
AVG. With selection of AVG in menu level DISPL the result is shown in the display and evaluated
when entered in the alarm AL1-Al4 or the analog output Outpt.
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.10 is set, the display would show a zero in the value range from -10 to +10;
below continue with -11 and beyond with +11. The maximum adjustable range of value is 99.

Menu level
Parameterisation level
Solid contstant value, const:
Default: 0
The constant value can be evaluated like the current measurand via the alarms or the analog
output. The decimal place cannot be changed for this value and is taken over from the current
measurand. So, with this value a setpoint generator can be realised via the analog output.
Furthermore it can be used as calculated difference. At this the constant value needs to be
subtracted from the current measurand and the difference is evaluated in the alerting or via the
analog output. Thus regulation can be displayed quite easy with this parameterisation.
Minimum constant value, con.mi:
Default: -i9999
The minimum constant value is selected and adjusted from the smallest to the highest digit with
[▲] [▼] 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 selected and adjusted from the smallest to the highest digit
with [▲] [▼] 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 measuring value, the min-value, the max-value, the totaliser, the
process-controlled hold value, the sliding average value, the constant value or the difference
between constant value and current value can be allocated to the display. With [P] the
selection is confirmed and the device changes into menu level.
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 correction LI.12 or LI.34 is choosen, the values of the
threshold can be changed during operation without disturbing the operating procedure. With
tArA the device is set temporarily on a parameterised value. The device acknowledges the
correct taring with oo0oo in the display. Set.tA switches into the offset value and can be adjusted
via the navigation keys. 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 is deposited, the totaliser
can be set back by pressing of the navigation keys [▲] [▼], the device acknowledges this with
ooooo in the display. By allocation on EHt.rE the min/max-memory is deleted. At ActuA the
measuring value is shown, after this the device switches back on the parameterised display
value. With light the brightness of the display is adjusted. This setting is not saved and gets lost
at a restart fo the device. Via selection L1.1, L1.1-2, li.1-3, l1.1-4, in case of 8 switching points li.15…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.

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 max. 100 seconds; there
is no monitoring with an input of 000. The timeout is adjusted from the smallest to the largest

difference between current measurand and constant value. If HoLd is selected, the signal of the
analog output will be kept. It can be continued processing after a deactivation of Hold. With [P]
the selection is confirmed and the device changes into menu level.
Selection analog output, Out.rA:
Default: 4-20
Three output signals are available: 0-10 VDC, 0-20 mA and 4-20 mA. Select the desired signal
with this function.
Setting the final value of the analog output, Out.En:
Default: 10000
The final value is adjusted from the smallest to the highest digit with [▲] [▼] and confirmed
digit per digit with [P]. A minus sign can only be parameterised on the highest digit. After the
last digit the device changes back into menu level.
Setting the initial value of the analog output, Out.OF:
Default: 00000
The initial value is adjusted from the smallest to the highest digit with [▲] [▼] and confirmed
digit per digit with [P]. A minus sign can only be parameterised on the highest digit. After the
last digit the device changes back into menu level.

Overflow behaviour, O.FLoU:
Default: edge
To recognise and evaluate faulty signals, e.g. by a controller, the overflow behaviour of the
analog output can be defined. As overflow can be seen either EdGE, that means the analog
output runs on the set limits e.g. 4 and 20 mA, or to.OFF (input value smaller than initial value,
analog output switches on e.g. 4 mA), to.End (higher than final value, analog output switches on
e.g. 20 mA). If to.MIn or to.MAX is set, the analog output switches on the smallest or highest
possible binary value. This means that values of e.g. 0 mA, 0 VDC or values higher than 20 mA
or 10 VDC can be reached. With [P] the selection is confirmed and the device changes into
menu level.

Each setpoint (optional) can be linked up via 4 alarms (by default). This can either be inserted
at activated alarms AL1/4 or deactivated alarms ALN1/4. If LOGIC is selected, logical links are
available in the menu level LoG-1 and CoM-1. One can only get to these two menu levels via LOGIC,
at all other selected functions, these two parameters are overleaped. Via On/OFF the setpoints
can be activated/deactivated, in this case the output and the setpoint display are set/not set on
the front of the device. The parameters Cal, Cal.of and CAL.en can only be used in accordance
with the semi-automatic calibration (Chapter 9. Sensor alignment). At Cal the relay switches
during sensor calibration, at cal.of during offset calibration and at Cal.en during the calibration of
the final value. With [P] the selection is confirmed and the device changes into menu level.

Dependency alarm 1, ALrM.1:
Default: actua
The dependency of alarm.1 can be related to special functions, in detail these are the current
measuring value, the min-value, the max-value, the totaliser value/sum value, the constant
value or the difference between the current measurand and the constant value. If Hold was
selected, the alarm is hold and processed just after deactivation of HOLD. EHtEr causes the
dependency either by pressing the [O]-key on the front of the housing or by an external signal
via the digital input. With [P] the selection is confirmed and the device changes into menu level.
Example:
By using the maximum value Alarm.1 = Max.va in combination with a threshold monitoring
Fu-1 = High, an alarm confirmation can be realised. Use the navigation keys, the 4th key or the
digital input for confirmation.

Threshold values / limit values, LI-1:
Default: 2000
The limit value defines the threshold, that activates/deactivates an alarm.
Hysteresis for threshold values, HY-1:
Default: 00000
The delayed reaction of the alarm is the difference to the threshold value, which is defined by
the hysteresis.
Function for threshold value undercut / exceedance, Fu-1:
Default: high
A limit value undercut is selected with Louu (for LOW = lower limit value), a limit value
exceedance with High (for HIGH = higher limit value). If e.g. limit value 1 is on a threshold level
of 100 and allocated with function High, an alarm is activated by reaching of the threshold level.
If the threshold value was allocated to Low, an alarm will be activated by undercutting the
threshold value, as long as the hysteresis is zero.
Switching-on delay, ton-1:
Default: 000
For limit value 1 one can preset a delayed switching-on of 0-100 seconds.

7. Alarms / Relays
7. Alarms / Relays
This device has 4 virtual alarms that can monitor one limit value in regard of an undercut or exceedance.
Each alarm can be allocated to an optional relay output S1-S2; furthermore alarms can be controlled by
events like e.g. hold-value or min/max-value.
Function principle of alarms / relays
Alarm / Relay x
Deactivated, instantaneous value, min/max-value, hold value, totaliser
value, sliding average value, constant value, difference between
instantaneous value and constant value or an activation via the digital
input
Switching threshold
Threshold / limit value of the change-over
Hysteresis
Broadness of the window between the switching thresholds
Working principle
Operating current / quiescent current
Operating current
By operating current the alarm S1-S2 is off
below the threshold and on on reaching the
threshold.
Quiescent current
By quiescent current the alarm S1-S2 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 short-term
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 parametrised time.

8. Interfaces
8. Interfaces
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 (sense). 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 M3-36-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 M3-36-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 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.
