1. Brief description
The panel meter instrument M2-14H is a 5-digit device for AC current / AC voltage signals
(TRMS) and a visual threshold value monitoring via the display. The configuration happens via
four keys at the front or by 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 the following functions are available: a digital input for triggering of
Hold (Tara), aswell as one analog output for further evaluating in the unit.
With help of the galvanic isolated setpoints (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 presetting or setpoint presetting, a direct threshold value regulation during
operation mode and further measuring setpoints for linearisation, complete the modern device
concept.

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 under menu item .
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
under menu item .
Parameterisation level:
Parameters 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. 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 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 happens via a 4-pole micromatch-plug on the back side of the device, to the PC-
side the connection happens 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 saved 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.

5.1. Switching on
Once the installation is complete, 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 ( ) 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 .

widespread detuning of the melt pressure sensors.
Setting up the physical unit,
Default:
One can choose between the above shown physical units. It will be displayed on
the 5th digit of the display.
Number of additional setpoints,
Default:
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,
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

increments 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

averaging results of the product of measuring time and the averaged metering
. With the selection of in the menu level the result will be shown in the
display and evaluated via the alarms.
Zero point slowdown,
Default:
At the zero point slowdown, a value range around the zero point can be preset, so
the display shows a zero. If e.g. a 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

Suppression of negative Offsets, :
Default:
This function can be used to suppress negative display values. When ON, the
function is active and all measured values below OFFS (measurand of initial
value) are ignored, OFF is selected and negative numerical values are displayed,
all measured values are linearized. With [P] the selection is confirmed and the
display changes to the menu level.
Definite contstant value, :
Default:
The constant value can be evaluated via the alarms or via the analog output, like
the current measurand. The decimal place cannot be changed for this value and is
taken over by the current measurand. Like this a setpoint generator can be
realised via the analog output by this value. Furthermore it can be used for
calculating the difference. At this the constant value is substracted from the current
measurand and the difference is evaluated in the alerting or by the analog output.
Thus regulations can be displayed quite easily.
Minimum constant value, :
Default:
The minimum constant value is adjusted from the smallest to the highest digit with
the navigation keys [▲] [▼]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, :
Default:
The maximum constant value is adjusted from the smallest to the highest digit with

Brightness control, :
Default:
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

Assignment (deposit) of key functions,
Default:
For the operation mode, special functions can be deposited on the navigation keys

which do not have a 4th key ([O]-key). If the min/max-memory is activated with

recalled via the navigation keys. The values get lost by restart of the device. If the
threshold value correction or is choosen, the values of the threshold can
be changed during operation without disturbing the operating procedure. With
the device is tared to zero and saved permanently as offset. The device confirms
the correct taring by showing ooooo in the display. switches into the offset
value and can be changed via the navigation keys [▲] [▼]. Via the current
value of the totaliser can be displayed, after this the device changes back on the
parameterised display value. If is deposited, the totaliser can be set back by
pressing of the navigation keys [▲] [▼], the device acknowledges this with ooooo
in the display. The configuration of deletes the min/max-memory. Under
the measurand is shown, after this the display returns to the parameterised
display value. If (absolute value) was selected, the display shows the value
that has been measured since voltage connection, without consideration of a
previous taring. Via selection , , , 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 is selected, the navigation keys are without any function in the operation
mode.
