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 insulated 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.
Selcetable 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.

2. Assembly
Please read the Safety advice on page 32 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 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:
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 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 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 is
done via a 4-pole micromatch-plug on the back side of the device, to the PC-side the connection ist done 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 safed 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, you can 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 (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.
5. Setting up the device
5. Setting up the device
Setting the end value of the measuring range, 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 a sensor calibration 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 the start/offset value of the measuring range, 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 a sensor
calibration 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.
Selection of the input signal, tYPE:
Default: s.600u
There are several measuring input options: 0-600/-300 VAC or 0-5/-1 AAC signals as works
calibration (without application of the sensor signal) and S.600v, S.300v, se.5a and se.1a as sensor
calibration (with the sensor applied). Confirm the selection with [P] and the display switches
back to menu level.

5. Setting up the device
Setting up the initial value of the analog output, Out.OF:
Default: 00000
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.
Setting up the final value of the analog output, Out.En:
Default: 10000
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.
Threshold values / Limits, LI-1:
Default: 2000
This value defines the threshold, that activates/deactivates an alarm.
Selection of analog output, Out.rA:
Default: 4-20
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 display time, SEC:
Default: 1.0
The display time is set with [▲] [▼]. The display moves up in increments of 0.1 sec up to 1 sec
and in increments of 1.0 sec up to 10.0 sec. Confirm the selection by pressing the [P] button.
The display then switches back to the menu level again.
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.
