1. Brief description
The panel instrument M1-x2 is a 4-digit device for direct voltage signals (via Shunt) and a
visual limit value monitoring via the display. The configuration happens via three front keys
or via the optional PC-software PM-TOOL. An integrated programming lock prevents
unrequested changes of the parameter and can be unlocked again via an individual code.
The electrical connection happens on the rear side via plug-in terminals.
Selectable functions like e.g. the recall of the min/max-value, a zero point slowdown, a direct
change of the limit value in operating mode and additional measuring supporting points for a
linearisation of the input signal, complete the modern device concept.

Operation
The operation is divided into two different levels.
Menu Level
Here it is possible to navigate between the individual menu items.
Parameterization level:
The parameters stored in the menu item can be parameterized here.
Functions that can be adjusted or changed are always indicated with a flashing of the
display. Adjustments made at the parameterization level should be always confirmed by
pressing the [P] key to save them. However, the display automatically saves all adjustments
and then switches to operation mode if no further keys are pressed within 10 seconds.

4.1. Programming via configuration software PM-TOOL-MUSB4:
You receive the software on CD incl. an USB-cable with a device adapter. The connection is
done via a 4-pole micromatch connector plug on the back and the PC is connected via an
USB connector plug.
System requirements: PC with USB interface
Software: Windows XP, Windows Vista
With this tool the device configuration can be created, skipped and saved on the PC. Via the
easy to handle program surface the parameter can be changed, whereat the mode of
operation and the possible selection options can be preset via 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!

5. Setting up the device
5.1. Switching on
Once the installation is complete, you can start the device by applying the current loop.
Check beforehand once again that all the 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 start-up sequence, the device switches to operation/display mode.
5.2. Standard parameterization:
To be able 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
Parameterization level
Selection of the input signal, TYPE:
Default: sens
There are several measuring inputs options: 0-60 mV or 0-150 mV signals as the
works calibration (without application of the sensor signal) and Sens as the sensor
calibration (with the sensor applied). Confirm the selection with [P] and the display
switches back to menu level.
Setting the measuring range end value, END:
Default: 1000
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 Sens was
selected as the input option, one 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 measuring range start/offset value, offs:
Default: 0000
Enter the start/offset value from the smallest to the highest digit [▲] [▼] and
confirm each digit with [P]. After the last digit the display switches back to the
menu level. If Sens was selected as the input option, one 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.

5. Setting up the device
Menu level
Parameterization level
Setting the decimal point, dot:
Default: 0
The decimal point on the display can be moved with [▲] [▼] and confirmed with
[P]. The display then switches back to the menu level again.
Setting the display time, SEC:
Default: 01.0
dann
The display time is set with [▲] [▼]. The display moves up in increments of 0.1 up
to 1 second and in increments of 1.0 to 10.0 seconds. Confirm the selection by
pressing the [P] button. The display then switches back to the menu level again.
5.3. Programming interlock RUN
Activation/deactivation of the programming lock and completion of the
standard parameterization, run:
Default: uloc
Choose between the deactivated key lock Uloc (works setting) and the activated
key lock Loc with the aid of the [▲] [▼] keys. Make 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 the [▲] [▼] keys plus [P] to unlock the keyboard.
FAIL appears if the input is wrong.

5. Setting up the device
5.4. Extended parameterization
By pressing the [▲] & [▼] keys during standard parameterization for one second, the
display switches to the extended parameterization mode. Operation is the same as in
standard parameterization.
Menu level
Parameterization level
Rescaling the measuring input values, EndA:
With the aid of this function, one can rescale the input value of e.g. 50 mV (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 the aid of this function, one can rescale the input value of e.g. 0,5 mV (works
setting) without applying a measuring signal. If sensor calibration has been
selected, these parameters are not available.
Setting the tare/offset value, tArA:
Default: 0
The given value is added to the linerarized value. In this way, the characteristic
line can be shifted by the selected amount.
Zero point slowdown, ZErO:
Default: 0
With zero point slowdown, a value range around zero can be preselected at which
the display shows zero. If, for example, a 10 is set, the display would show a zero
in the range from -10 to +10 and continue below it with -11 and above it with +11.
7
5. Setting up the device
Menu level
Parameterization level
Min/max-value inquiry - assignment of key functions, Tast:
Default: no
For the operating mode enter here either a min/max-value inquiry or a threshold
value correction on the arrow keys.
If the min/max-memory was activated with EHER, the measured min/max-values will
be saved during operation and can be called up via the arrow keys [▲] [▼]. The
values are lost if the device is restarted.
If the threshold value correction LI.1 was selected, the limit values can be changed
during operation without hindering the operating procedure.
With tara the display is tared to zero and is saved permanently as offset. The
device confirms the correct taring by showing 0000 in the display. If No was
parameterized, the navigation keys [▼] [▲] have no function in operating mode.
Flashing of display, FLAS:
Default: no
Here, the flashing of the display can be added as an extra alarm function, either to
the first limit value (select: LI-1), the second limit value (select: LI-2) or to both limit
values (select: LI-12). With No (works setting), no flashing is assigned at all.
Limit values, LI-1:
Default: 0200
For both limit values, two different values can be parameterized. With this, the
parameters for each limit value are called up one after the other.
Hysteresis for limit values, HY-1:
Default: 0000
For both limit values, a hysteresis function exists that reacts according to the
functional principle (operating current / quiescent current).

5. Setting up the device
Menu level
Parameterization level
Function if display falls below / exceeds limit value, FU-1:
Default: hi9h
To indicate if the value falls below the lower limit value, Louu can be selected
(LOW = lower limit value) and if it goes above the upper limit value, high can be
selected (HIGH = upper limit value). LOW corresponds to the quiescent current
principle and HIGH to the operating current principle.
Limit value, LI-2:
Default: 0300
For both limit values, two different values can be parameterized. With this, the
parameters for each limit value are called up one after the other.
Hysteresis for limit values, HY-2:
Default: 0000
For both limit values, a hysteresis function exists that reacts according to the
functional principle (operating current / quiescent current).
Function if display falls below / exceeds limit value, FU-2:
Default: hi9h
To indicate if the value falls below the lower limit value, Louu can be selected
(LOW = lower limit value) and if it goes above the upper limit value, high can be
selected (HIGH = upper limit value). LOW corresponds to the quiescent current
principle and HIGH to the operating current principle.
9
5. Setting up the device
Menu level
Parameterization level
Setting the code, CODE:
Default: 1234
With this setting, it is possible to select an individual code (works setting 1 2 3 4) for
locking the keyboard. To lock/release the key, proceed according to menu item
run.
Supporting points - number of additional supporting points, SPCt:
Default: 0
In addition to the start and end value, 8 extra supporting points can be defined to
linearise non-linear sensor values. Only the activated set point parameters are
displayed.
Display values for supporting points, dIS1 … dIS8:
Under this parameter the supporting points are defined on a value basis. At the
sensor calibration one will be asked at the end (like at final value/offset, too), if a
calibration shall be triggered.
Analogue values for supporting points, INP1 … INP8:
Supporting points are always preset according to the selected input signal mV.
Here the desired analog values can be freely adjusted in ascending order.
10
6. Reset to default values
6. Reset to default values
To return the unit to a defined basic state, a reset can be carried out to the default values.
The following procedure should be used:
• Switch off the power supply
• Press [P]-button
• Switch on voltage supply and press [P]-button until „- - - -“ is shown in the display.
With reset, the default values of the program table are loaded and used for subsequent
operation. This sets the unit back into the state in which it was supplied.
Caution! All application-related data are lost.

9. Safety advices
9. Safety advices
Please read the following safety advices and the assembly chapter 2 before installation and
keep it for future reference.
Proper use
The M1-x2-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 M1-x2-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 0.5A 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 freewheeling diodes.
• Keep input, output and supply lines separate from each other and do not lay them parallel
with each other. Position “go” and “return lines” next to one another. Where possible use
twisted pair. So, the best measuring results can be received.
• 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.
