1. Brief description
1. Brief description
The panel meter IM2 is a 5-digit device for direct voltage signals and a visual threshold value monitoring via
the display. The configuration happens via four front keys or via the optional PC software PM-TOOL. An
integrated programming interlock prevents unrequested changes of the parameters and can be unlocked
again by an individual code. Optional the following functions are available: a supply for the sensor, a digital
input for triggering of Hold (Tara) or an analog output for further processing in the equipment.
By use of the two optional galvanic isolated setpoints, free adjustable threshold values can be controlled and
reported to a superior master display.
The electrical connection is carried out on the back side via plug-in terminals.
Selectable functions like e.g. the request of the min/max-value, an average determination of the measuring
signals, a nominal preset respectively setpoint preset, a direct change of threshold value in operation mode
and additional measuring supporting points for linearisation complete the modern device concept.

4. Function and operation description
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, 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 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.

Parameterisation level
User code (4-digit number-combination, free available), U.CodE:
Default: 0000
If this code is set (>0000), all parameters are locked for the user, if LOC has been selected under
menu item run. By pressing [P] for approx. 3 seconds in operation mode, the message CODE is
shown in the display. Enter the preset u.code to get access to the set of parameters which are
released for the user. The code needs to be entered bevor each try of parameterisation, as
long as A.Code (Master code) all parameters are released again.
Master code (4-digit number-combination free available), A.CodE:
Default: 1234
After LOC has been activated under menu item Run, this code can be used for releasing all
parameters. By pressing [P] for approx. 3 seconds in operation mode, the message CODE is
shown in the display and offer the user access to all parameters by entering A.codE. While
leaving this parameterisation it can be released permanently under run by selecting ULOC or
ProF. So, at an anew pressing of [P] in operating mode, an anew entereing of the code is not
needed.
5.3. Programming interlock „run“
Activation / Deactivation of the programming interlock or completion of the standard
parameterisation with change into menu group level (complete function volume), run:
Default: uloc
With the navigation keys [▲] [▼], choose between the deactivated key lock Uloc (works
setting), 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 1234) 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 into 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 as long activated as ULOC is entered in
menu group RUN, thus the display is set back in standard parameterisation again.

Parameterisation level
Number of additional setpoints, SPCt:
Default: 00
30 additional setpoints 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 setpoints, dIS.01 … dIS.30:
Under this parameter setpoints 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 setpoints, InP.01 … InP.30:
The setpoints are always preset according to the selected input signal mA/V. The demanded
analog values can be freely adjusted in ascending order.
Device undercut, dI.Und:
Default: -i9999
With this function the device undercut (_ _ _ _ _) can be defined on a definite value. Exception is

The display time is set up with [▲] [▼]. Thereby you switch up to 1 second in increments of
0.1 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 steps 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 calulation 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.

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 measurand, the min/max-value, the totaliser, the processcontrolled 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 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
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 for approx.
7 seconds, 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 for approx. 7 seconds, after this the device
switches back on the parameterised display value With light the brightness of the display is
adjusted. This setting is not safed and gets lost at a restart fo the device. Via selection L1.1, L1.1-2,
li.1-3, l1.1-4 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

function by pressing the key. With tArA the device is set temporarily on zero and safed
permanently as offset. The device acknowledges the correct taring by showing ooooo in 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 for approx. 7 seconds, 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. EHt.rE deletes the min/max-memory. 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 is selected under parameter DISPL. ActuA shows the measuring value for
approx. 7 seconds, after this the device switches back on the parameterised display value. The
same goes for AvG, here the sliding average value will be displayed. Via se.cal a sensor
calibration is done by pressing the zero key, the operating diagram is shown in chapter 8. The
constant value const can be called up via the key or adjusted digit per digit. At AL-1…AL-4 an

The analog output signal can refer to different functions, in detail this are the current
measurand, min/max-value or totaliser function/sum-function, the sliding average value, the
constant value or the difference between the current value and the constant value. If HoLd is
selected the signal of the analog output will be hold and processed just after deactivation of
HOLD. With [P] the selection is confirmed and the device changes into menu level.
Selection analog output, Out.rA:
Default: 4-20
There are 3 output signals availabe: 0-10 VDC, 0-20 mA and 4-20 mA. With this function the
demanded signal can be selected.
Setting up the final value of the analog output, Out.En:
Default: 10000
The final value can be adjusted from the smallest to the largest digit with [▲] [▼]. 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.

last digit, the display switches back to the menu level.
Overflow behavior, O.FLoU:
Default: edge
To recognise and evaluate faulty signals, e.g. by a controller, the overflow behavior 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 mA and 20 mA, or to.OFF (input value smaller than initial
value, analog output changes on e.g. 4 mA), to.End (higher than final value, analog output
changes on e.g. 20 mA). If to.MIn or to.MAX is set, the analog output changes 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.

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 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. Sensor calibration offset / final value
8. Sensor calibration offset / final value
The device is equipped with a semi-automatic sensor calibration (Su.x). 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.

10. Safety advices
10. Safety advices
Please read the following safety advice and the assembly chapter 1 before installation and keep it
for future reference.
Proper use
The IM2-12-deviceis 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 IM2-12-devicemust 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.
