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!
2. Assembly
The panel meter M3-3F can evaluate pulses in many different ways and show the result in the 5-digit LED-
display. Available options are: frequency coverage with optional filters, summate of pulses or display values via
time, detection of a rotational speed or collection of a position via an incremental encoder. The results can be
monitored via alarm conditions and can be displayed onto the optional switching point. Furthermore the results
can be freely scaled on an optional analog output and relayed to a control system. The device can be operated
directly by Namur sensors, 3-wire sensors, switching/slider contacts, incremental encoders (HTL-/TTL-output)
or TTL-signals.
Via the 3 navigation keys on the front, the device can be adjusted onto different kind of applications and later on
different functions of the device can be controlled. The adjustment is also possible via the PC-Software PM-
TOOL with a special connecting cable. With an individual code, the created parameterisation can be protected
against changes of the user.
Numerous applications can be realised with this device, like e.g. tachometer, revolution counter, flowmeter,
dosing equipment, filling capacity meter, baking time meter of a baking oven, flying knife, position evaluation,
position surveillance, flow rate surveillance, acoustic discharge measurements and so on. By use of the
integrated, configurable functions like permanent min/max-recording, averaging, frequency filter, setpoint
setting, threshold value recording via alarm system, 30-points-linearisation, mathematic charging and many
more, you receive an universal applicable modern instrument for your demands in measuring and control
technique.

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 by pushing both navigation keys
at the same time.
Parameterisation
level
To confirm the changes made at the parameterization level.
Adjustment of the value / the setting.
Change into menu level or stop of the value input, by pushing
both navigation keys at the same time.
Menu group level
Change to menu level.
Keys for up and down navigation in the menu group level.
Change into operation mode or return into menu level, by
pushing both navigation keys at the same time.
Operation
The operation is divided into three different levels.
Menu level (delivery status)
The menu level is designed for the standard settings of the device. Only menu items which are sufficient 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:
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 saved. Pressing the [O]-key („zero-key“) 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 it
changes into operating mode, if no further key operation is done within the next 10 seconds.

4. Function and operation description
4.1 Parameterisation software PM-TOOL:
Included in the delivery 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.

Menu level Parameterisation level
Selection of the input signal,
Default:
If the scaling of the device is done via (Sensor calibration), the frequency range needs to
be preset under and is adjusted by application of the final value/initial value. If
(Factory calibration) is preferred, the final value needs to be entered under and the final
frequency needs to be entered under . Under the initial value needs to be entered and
under the initial frequency. There is no application of the measuring signal. Confirm the
selection with [P] and the display switches back to menu level.
Adjustment of pulses per rotation, :
Default:
This parameter is only important if = or = have been selected. Generally it
shows the number of pulses per rotation.
Setting end value of the measuring range, :
Default:
Choose between six different frequency ranges. Confirm the selection with [P] and the display
switches back to menu level.
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 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 .

Menu level Parameterisation level
Setting the final value of the measuring range, :
Default:
Set the final value from the smallest to the highest digit with [▲] [▼] and confirm each digit
with [P]. A minus sign can only be parameterized on the leftmost digit. After the last digit, the
display switches back to the menu level. If was selected as input option, you 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 start/offset value of the measuring range, :
Default:
Enter the start/offset value from the smallest to the highest digit [▲] [▼] and confirm each digit
with [P]. After the last digit the display switches back to the menu level. If was selected
as the input option, you 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.
Rescaling the measuring input values,
Default:
With this function, you can rescale the input value of e.g. 8.000 Hz (works setting) without
applying a measuring signal. If sensor calibration has been selected, these parameters are not
available.
