1. Brief description
The panel meter instrument M2-1F is a 5-digit device for pulse signals, respectivley 2- and 3-wire
sensors. The configuration happens via four keys at the front. 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 supply for the sensor, a digital input for triggering of
Hold (Tara), one analog output or switching outputs for further evaluating in the unit.
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, digital frequency filter for contact bounce suppression
and disturbance suppression with adjustable key relation, a direct threshold value regulation during
operation mode and further measuring setpoints for linearisation, complete the modern device
concept.

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. 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 „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.

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.

Setting end value of the measuring range, END:
Default: 100e3
Choose between six different frequency ranges. Confirm the selection with [P] and the display
switches back to menu level.
Setting the final value of the measuring range, END:
Default: 10000
Set the final value from the smallest to the highest digit with [▲] [▼] and confirm each digit with
[P]. A minus sign can only be parametrized 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.
Selection of the input signal, TYPE:
Default: frequ
If the scaling of the device is done via SEnS.F (Sensor calibration), the frequency range needs to
be preset under rAnGE and is adjusted by application of the final value /initial value. If FrEqU
(Factory calibration) is preferred, the final value needs to be entered under End and the final
frequency needs to be entered under EndA. Under OFFS the initial value needs to be entered and
under OFFSA the initial frequency. There is no application of the measuring signal. Confirm the
selection with [P] and the display switches back to menu level.
Parameterisation levelMenu level
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. Setting up the device
5.2. Standard parameterisation: (flat operation level)
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.
