1. Brief description
The panel meter instrument M2-14 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.

Please read the Safety advices on page 34 before installation and keep this user manual for
future reference.
1. After removing the fixing elements, insert the device.
2. Check the seal to make sure it fits securely.
3. Click the fixing elements back into place and tighten the clamping screws by hand. Then use
a screwdriver to tighten them another half a turn.
CAUTION! The torque should not exceed 0.1 Nm!
The dimension symbols can be exchanged before installation via a channel on the side!

4. Description of function and operation
Operation
The operation is divided into three different levels.
Menu level (delivery status)
This level is designed 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.
Level Key Description
Menu level
Change to parameterisation level and deposited values.
Keys for up and down navigation in the menu level.
Change into operation mode.
Parameterisation
level
Confirms the changes made at the parameterisation level.
Adjustment of the value / the setting.
Change into menu level or break-off in value input.
Menu group level
Change to menu level.
Keys for up and down navigation in the menu group level.
Change into operation mode or back into menu level.

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 .
5. Setting up the device
5. Setting up the device
Menu level Parameterisation level
Selection of the input signal,
Default:
Available as measuring input options are 0-50 VAC/0-10 VAC or 0-5 AAC/0-1 AAC
signals as works calibration (without application of the sensor signal) and
and as sensor calibration (with the sensor applied). Select with
[▲] [▼] and confirm the selection with [P].
Setting the end value of the measuring range, :
Default:
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 was
selected as input option, one can only select between and With , only
the previously set display value is taken over, and with , the device takes over
both the display value and the analogue input value.

5. Setting up the device
Menu level Parameterisation level
Setting the start/offset value of the measuring range, :
Default:
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 was selected as input option, one can only select between
and With , only the previously set display value is taken over, and with ,
the device takes over both the display value and the analogue input value.
Setting the decimal point, :
Default:
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 up the display time, :
Default:
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 up to 10.0 seconds. Confirm the selection by
pressing the [P] button. The display then switches back to the menu level again.
Selection of analog output,
Default:
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,
Default:
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 parameterised on
the highest digit. After the last digit, the device changes back into menu level.
