Operation
The operation is divided into three different levels.
Menu level (delivery status)
This level is 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, totalisator
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 safed. By pressing the
„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 changes into operating mode, if no
further key operation is done within the next 10 seconds.

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.
Menu level
Parameterisation level
Selection of the input signal, TYPE:
If the scaling of the device is done via SEnS.F (Sensor calibration), the frequency range
needs to be preset under rAnGE and is adjusted by application of the final value /initial
value. If FrEqU (Factory calibration) is preferred, the final value needs to be entered
under End and the final frequency needs to be entered under EndA. Under OFFS the initial
value needs to be entered and under OFFSA the initial frequency. There is no
application of the measuring signal. Confirm the selection with [P] and the display
switches back to menu level.
Setting the measuring range end value, END:

display switches back to menu level.
Setting the measuring range final value, END:
Set the final value from the smallest to the largest digit with [▲] [▼] and confirm each
digit with [P]. A minus sign can only be parametrized on the highest value digit. 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.

to 1 sec and in increments of 1.0 sec up to 10.0 sec. Confirm the selection by pressing
the [P] button. The display then switches back to the menu level again.
Rescaling the measuring input values, EndA:
With this function, you can rescale the input value of e.g. 19.5 mA (works setting)
without applying a measuring signal. If sensor calibration has been selected, these
parameters are not available.
Rescaling the measuring input values, OFFA:
With this function, you can rescale the input value of e.g. 3.5 mA (works setting)
without applying a measuring signal. If sensor calibration has been selected, these
parameters are not available.

Menu level
Parameterisation level
Setting of the impulse delay, dELAY:
With the impulse delay of 0 – 250 ms (max), frequencies can be collected, which are
even smaller than by the predetermined measuring time of the device. If e.g. a delay
of 250 seconds is set, this means that the device waits up to 250 seconds for an edge,
before it assumes a 0 Hz-frequency. Thus frequencies up to 0.004 Hz can be
collected.
Selection of analog output, Out.rA:
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:
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 parametrised 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:
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 parametrised on the highest
digit. After the last digit, the device changes back into menu level.
Threshold values / limit values, LI-1:
For both limit values, two different values can be parameterized. With this, the
parameters for each limit value are called up one after another.

4. Setting up the device
Menu level
Parameterisation level
Hysterisis for limit values, HY-1:
For all limit values exists a hysterisis function, that reacts according to the settings
(threshold exceedance / threshold undercut).
Function if display falls below / exceeds limit value, FU-1:
The limit value undercut can be selected with Louu (LOW = lower limit value) and limit
value exceedance can be selected with high (HIGH = upper limit value). If e.g. limit
value 1 is on a switching threshold of 100 and occupied with function „high“, the alarm
will be activated by reaching the threshold. If the limit value is allocated to „Low“, an
alarm will be activated by undercut of the threshold. See page 29.
Threshold values / limit values, LI-2:
For both limit values, two different values can be parameterized. With this, the
parameters for each limit value are called up one after another.
Hysterisis for limit values, HY-2:
For all limit values exists a hysterisis function, that reacts according to the settings
(threshold exceedance / threshold undercut).
Function if display falls below / exceeds limit value, FU-2:
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. By allocation of limit value Louu , an alarm is activated
by falling below the threshold value.

Parameterisation level
User code (4-digit number-combination, free available), U.CodE:
If this code is set, the user can only choose from a reduced number of parameter sets.
He has e.g. no access to the scale of the measuring inputs. Still, a changing of the
limit values and the allocation of the analog output are allowed. This reduced
parameterisation is activated by selecting LOC in menu item run. The device confirms
the setting with „- - - - -„ and changes into operation mode. By pressing [P] for 3
seconds in operation mode, the display shows COde and thus confirms the change into
the reduced parameterisation. It stays activated as long as the standard
parameterisation is activated again by the input of A.Code (master code).
Master code (4-digit number-combination free available), A.CodE:
No parameterisation is allowed if this code is set. This function ist activated by
selecting LOC in menu item run. The device confirms the setting with „- - - - -„ and
changes into operation mode. By pressing [P] for 3 seconds in operation mode, the
display shows COde and thus confirms the activation of the master code. The user can
only come to the parameterisation by the correct input of the number-combination. It
stays activated as long as ULOC is entered in menu group run, this sets the device back
into standard parameterisation.
Activation / deactivation of the programming lock or completion of the standard
parameterization with change into menu group level (complete function range),
run:
With the navigation keys [▲] [▼], you can choose between the deactivated key lock
Uloc (works setting) and the activated key lock Loc, or 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 parametrise 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 is entered in menu group RUN , thus the display is set back in standard
parameterisation again.

Setting up the tare/offset value, tArA:
The given value is added to the linerarized value. In this way, the characteristic line
can be shifted by the selected amount.
Number of additional setpoints, SPCt:
30 additional setpoints can be defined to the initial- and final value, so linear sensor
values are not linearised. Only activated setpoint parameters are displayed.
Display values for setpoints, dIS.01 … dIS.30:
Under this parameter setpoints are defined according to their value. At the sensor
calibration, like at Endwert/Offset, one is asked at the end if a calibration shall be

Assignment (deposit) of key functions, tASt:
For the operation mode, special functions can be deposited on the navigation keys
[▲] [▼], in particular this function is made for devices in housing size 48x24 which do
not have a fourth key ( [O] key). If the MIN-/MAX-memory is activated with EHtr, all
measured MIN/MAX-values are safed during operation and can be recalled via the
navigation keys. The values get lost by re-start 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 parametrised value. The device acknowledges the correct taring with
oo0oo in the display. Set.tA adds a defined value on to the currently displayed value. Via
totAL the current value of the totalisator can be displayed for approx.
7 seconds,
after this the device jumps back on the parametrised display value. If tot.rE is deposited,
the totalisator can be set back by pressing of the navigation keys [▲] [▼], the device

Dependency alarm1, ALrM.1:
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 or the totalisator-/sum-value.
Is Hold selected, then 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 devices changes into menu level.

Parameterisation level
Threshold values / limit values, LI-1:
For both limit values, two different values can be parameterized. With this, the
parameters for each limit value are called up one after another.
Hysterisis for limit values, HY-1:
For all limit values exists a hysterisis function, that reacts according to the settings
(threshold exceedance / threshold undercut).
Function if display falls below / exceeds limit value, FU-1:
The limit value undercut can be selected with Louu (LOW = lower limit value) and limit
value exceedance can be selected with high (HIGH = upper limit value). If e.g. limit
value 1 is on a switching threshold of 100 and occupied with function „high“, the alarm
will be activated by reaching the threshold. If the limit value is allocated to „Low“, an
alarm will be activated by undercut of the threshold.
Switching-on delay, ton-1:
For limit value 1 one can preset a delayed switching-on of 0-100 seconds.
Switching-off delay, toF-1:
For limit value 1 one can preset a delayed switching-off of 0-100 seconds.

4.4. 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 or Min-/Max-value.

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 seonds
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.

7. Safety advices
7. Safety advices
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.
