1. Brief description / 2. Assembly
1. Brief description
The panel instrument M1-1U is a 4-digit device for measuring of different kind of measuring signals such as
direct voltage/direct current, temperature and frequency and a visual limit value monitoring via the display.
The configuration happens via three front keys or via the optional PC-software PM-TOOL. An integrated
programming interlock prevents unrequested changes of the parameter and can be released again via an
individual code. The electrical connection happens on the rear side via plug-in terminals.
Selectable functions like e.g. the recall of the min/max-value, Tara-function, averaging, a direct change of
the limit value in operating mode and additional measuring support points for linearisation complete the
concept of a modern device.
2. Assembly
Please read the Safety instructions on page 23 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!

4. Description of function and operation
4. Description of function and operation
The device comes with three keys, which are used for parameterisation of the device and whose deposited
functions can be called up during operation. Functions, that can be adjusted or changed are always signalised
by a flashing of the display. Adjustments that were made in the „Parameterisation level“ are always confirmed
with [P] and thus saved. The device saves however automatically all adjustments and changes back into
operating mode, if no more key actuation takes place within 10 seconds.
4.1. Operating and display elements
Key symbol Function in operating mode Function at parameterisation
Program key [P] Change the parameterisation with program
key [P].
Change into a lower parameterisation
-level or to deposited values.
Minus key [▼]
Depending on adjusted key functions, use
the minus key [▼] for calling up the
minimum value or changing a lower limit
value.
Change between parameter and
changing of parameter within the
value level.
Plus key [▲]
Depending on adjusted key functions, use
the plus key [▲] for calling up the
maximum-value or changing a lower limit
value.
Change between parameter and
changing of parameter within the
value level.
Numerical values are adjusted from the smallest to the highest digit with [▲] [▼] and confirmed digit per digit
with [P]. A minus sign can only be adjusted on the leftmost digit. After the last digit, the display changes back
into menu-level.
Example: Setting up the device parameter, e.g. selection of the input signal
Parameter Choice
Example: Setting up numerical values, e.g. final value of measuring range
A switched-on relay or an activated switching point will be reported optically by a flashing of the respective
switching point LED next to the 7-segment display. A display over-/underflow is displayed by four bars „- - - -„.
4.2. Programming via configuration software PM-TOOL MUSB4:
The software comes on CD incl. an USB-cable with a device adapter. The connection happens via a 12-pole
micromatch connector plug on the back and the PC is connected via an USB connector plug.
System requirements: PC with USB interface
Software: Windows XP, Windows Vista
With this tool the device configuration can be created, readout and saved on the PC. Via the easy to handle
program surface the parameter can be changed, whereat the mode of operation and the possible selection
options can be preset via the program.
CAUTION!
During parameterisation with a connected measuring signal, make sure that the measuring signal has no mass
supply to the programming plug. The programming adapter is galvanically not isolated and directly connected
with the PC. Via polarity of the input signal, a current can discharge via the adapter and destroy the device as
well as other connected components!

6.1. Selection of the input signal: type
During the adjustment of the type, an allocation of the input version takes place. Selectable are 5 input
types: Voltage, Current, Pt100(0), Thermocouple and Pulse signal.
6. Parameterisation
5.1. Switching on
Once the installation is complete, start the device by applying the voltage supply. Check beforehand once
again that all the electrical connections are correct.
Starting sequence
For 1 second during the switching-on process, the segment test (88888) is displayed, followed by an
indication of the software type and, after that, also for 1 second, the software version. After the start-up
sequence, the device switches to operating/display mode.

Determine the decimal representation of the display value with the decimal point. It is used for the adjustment
of the limit values, too.

With this function the final value/initial value can be rescaled to e.g. 19.5mA/3.2mA without application of the

tArA: Setting up the Tara value / Offset value
The preset value is added to the linearised value. So the characteristic line can be shifted by the selected
amount.
ZErO: Zero-point slowdown
Here, a range of values around the zero-point can be preset, where the display shows a zero. If e.g. a 10 is
adjusted, the display would show a zero within a range of value of -10 to +10 and continue below with
-11 and above with +11.
OVEr: Overflow and underflow behaviour
The overflow/underflow of the measuring input will be signaled by 4 horizontal bars at the top respectively by 4
bars at the bottom. Exception is input type „4-20“ (mA), where a measurand smaller than 1 mA can already be
valuated as underflow. This shall indicate a sensor failure.
no No additional check of the range takes place. By leaving the display range, the display remains
on the smallest value „dI.Lo“ respectively highest value „dI.HI“.
AdC At exceedance/undercut of the display range „dI.Lo“ / „dI.HI“ over-/underflow will be displayed.
rAnG
The measuring signal needs to be exactly in the preset measuring range „EnD“/“OFFS“, so
that an overflow will not be detected. The display range and transformer range will be
monitored additionally.

6.1.3.2. Rotation speed measurement

500 500 Hz with pulse-duty factor 1:1 => minimal pulse length 1 ms
PPt: Pulse per rotation
With this parameter the number of pulse per rotation can be entered directly. It generally works with sprockets
and their number of sprockets, incremental encoder and their resolution or glands with a number of boreholes.
For simple flow meter with impeller it is only neccessary to enter the number of pulse per liter or cubic metre.
tIME: Time base
In general the time base for rotation speed is always set on „MIn“, it can of course be changed into seconds or
hours.
dot: Comma / decimal place
Determine the decimal representation of the display value with the decimal point. A rotation speed with up to 3
positions after decimal point can be displayed, if they are small enough.
Example: Rotation speed measurement
The rotation speed of a roller in a steel works needs to be displayed in turns/minute with one position after
decimal place. The rotational speed will be recorded via a perforated disc with 18 holes, positioned in an angle
of 20°. The maximum rotation speed of the roller is 60 turns/minute. Like this, adjust for example FILt =100;
PPt =18;tIME =MIn;dot =0.0. The difficulty with the adjustment of the filter is to calculate the pulse length
precisely.

PnP Active sensor output. A pull-down is operated in the device.
I.tYP: Pulse signal
There a three modes for the triggering of the pulse input:
Co.bA: Counter base
As standard the device records incoming pulses during counter operation. However the counter basis can also
be used as system time in seconds or minutes. In doing so the pulse input turns into gate time, it counts at
wing PoSI (HIGH-signal) and stands at LOW. The logic is contrary at wing nEGA.
EdGE: Counting start / counting end (wing)
The active wing declares when the counting takes place. The pulse recording PuLS is choosen as counter
basis, via this it will be declared if the internal counter will be increased by the positive wing PoSI or the
negative wing nEGA. If time is taken as time basis, then the active-triggering/HIGH-triggering will be selected
with PoSI and the passive triggering/LOW-triggering will be selected with nEGA. The counter reset is always
statical.
