1. Brief description
1. Brief description
The panel meter M2-1M is a 5-digit device for connection to a 4-wire-measuring bridge with
calibration contact (80% alignment) 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 10 V bridge feeding,
a digital input for the triggering of Hold (Tara) or the 80%-alignment and two optional galvanic
insulated setpoints, by which 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 (zerokey) 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.

5. Setting up the device
5.1. Switching-on
Once the installation is complete, you can start the device by applying the voltage supply. First, 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.
5.2. Standard parameterisation: (Flat operation level)
To parameterise 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

Selection of the input signal, tYPE:
Default: sens.f
There are 3 measuring input options available for known sensor sensibilities: SENS.1 for 1mV/V,
SENS.2 for 2mV/V and SENS.3 for 3,3mV/V. Each sensor is measured and calibrated up to 4mV/V
via SEnS.F. Confirm the selection with [P] and the display switches back to menu level.
Setting the measuring range end value, 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 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 up the measuring range start/offset value, 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.

The display then switches back to the menu level again.
Special function [O]-key, tASt.4:
Default: no
…
For the operation mode, special functions can be deposited on the [O]-Taste. This function is
activated by pressing the key. With tArA the display is tared to zero und safed permanently as
Offset. The device acknowledges the correct taring with oo0oo in the display. Set.tA switches
into the Offset value and can thus be changed via the navigation keys [▲] & [▼]. EHt.rE deletes
the min/max memory. ActuA shows the measurand, then the display changes onto the
parameterised display value. The same goes for AVG, here the sliding average value is
displayed. 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. If AbS.UA (absolute value) was selected, the display shows the values that have
been measured since the voltage has been connected, without consideration of a previous
taring. With t.tAra (temporarily Tara) the offset is determined by rising shoulder of the digital
input and kept only for the period of the signal. Via SE.CAL a sensor calibration is done by
pushing the zero-key, the flow diagram is shown in chapter 4.4. At AL-1…AL-8 an output can be
set and therewith e.g. a switch of the metering point can be done. If no is selected, the [O]-key
is without any function in the operation mode.

Threshold values / Limit values, LI-1:
Default: 2000
This limit value defines the threshold, that leads to an activation / deactivation of the alarm.
Hysteresis for limit values, HY-1:
Default: 0
The difference to the threshold value that causes the delay of the actuation of the alarm, is
defined by the hysteresis.
Function if display falls below / exceeds limit value, FU-1:
Default: high
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.

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 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 tared to zero and safed permanently as Offset. The device confirms the
correct taring by showing ooooo in the display. Set.tA changes into the offset value and can be

Depedency of alarm1, ALrM.1:
Default: actua
The dependency of alarm1 can be related to special functions, in detail these are the current
measurand, the min-value, the max-value, the absolute value or the sliding average value. If
Hold is selected the alram 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 or the fourth key for
confirmation.
Threshold values /Limits, LI-1:
Default: 2000
This limit value defines the threshold, that leads to an activation / deactivation of the alarm.
Hysteresis for threshold values, HY-1:
Default: 00000
The difference to the threshold value that causes the delay of the actuation of the alarm, is
defined by the hysteresis.
Function for threshold value exceedance/-undercut, Fu-1:
Default: high
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.

6. Reset to factoty settings
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 button [P]
• 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 to the state in which it was supplied.
Caution! All application-related data are lost.

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 or min-/max-value.
Function principle of alarms / relays

Working principle
Operating strom / 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 parameterised time.

8. Sensor calibration Offset / Final value
8. Sensor calibration Offset/Final value
The device has an automatic calibration at mass pressure sensors, where an integrated switching
output operates an often available 80% calibration. Like this offset and final value are adjusted, and
the sensor can be applied directly after this. The calibration can be done via the 4th key or the digital
input, depending on the parameterisation.

10. Safety advices
10. Safety advices
Please read the following safety advice and the assembly chapter 2 before installation and keep it
for future reference.
Proper use
The M2-1M-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 M2-1M-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.
