1. Brief description
Setpoint function
A setpoint generator enables the user to adjust operating parameters of a machine (like e.g. an
oven temperature, rotational speed or filling weight) in the most easiest way and relays it via the
integrated outputs to a superior control. Thereby the production engineer can determine the
adjustment range and thus guarantee a safe operation. This makes the setpoint generator an
ideal device for simple control with a few parameters or for a more complex regulation, where a
simple relation between setpoint value and the machine behavior that needs to be controlled is
not possible (e.g. the filling weight of an ampoule filling system).
For the setpoint generator the display value is changed manually by the user, depending on the
adjustment type via the front keys or via the digital inputs. The possible adjustment range is
definable via the parameters End and Offs. An output quantity Out.ra with the output range Out.En
to Out.OF is allocated to them. By changing the setpoint in the display, the initial value is linear
and carried isochronous. The following values result from a adjustment range of the setpoint from
0…2000 and an accordingly selected output range from 4…20 mA:
4 mA = 0
12 mA = 1000
20 mA = 2000
Additionally alarms can be used to warn the user about critical settings. To secure the favoured
setpoint against accidental adjustment, a releasing code S.Code can be activated or an electric
key-switch can be provided. If an external key-switch is used via digital input 1, then the device
shows a –LOC– in the display by any attempt of adjustment via the keys [▲] [▼].
By operating the setpoint via the front keys, a default value/initial value start can be recalled via
the navigation keys [▲] [▼]. It can be used for one system as emergency switch, too.
This initial value is loaded in the basic setting during system start and displayed. If L.star was
selected instead of l.save as reset behaviour reset, the device loads up the last adjusted effective
setpoint. The latter is safed approx. 1 minute after each change of the setpoint.
The two excisting digital inputs react depending on the setting of in.lev to a HiGh- or a Low- signal.

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. All adjustments are safed
automatically by the device and it changes into operating mode, if no further key operation is done
within the next 10 seconds.

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 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.
Menu level
Parameterisation level
Selection of the adjustment type for the setpoint / default value, TYPE:
Default: f.tast
With F.tASt the setpoint is adjusted by [▲] [▼], furthermore the adjusment can be locked via
the external input 1. At F.InPu there is a direct selective input of the setpoint via [P] [▲] [▼]. For
the adjustment the key [▲] or [▼] needs to be pressed first. Via input 1 the adjustment lock is
controlled. With E.tASt the adjustment of the setpoint via the external inputs 1 (+) and 2 (-) is
done. There is no additional input lock. This has to be realised by an electrical connection of the
keys if required. Confirm the selection with [P] and the display switches back to menu level.
Setting up the adjustment end value, 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 leftmost digit. After the last digit, the display
switches back to the menu level. The value that is set here, can later on not be exceeded while
adjusting the setpoint.
Setting up the adjustment start/offset value, offs:
Default: 0
Enter the start/offset 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. The value that is set here, can later on not be
undercut while adjusting the setpoint.
Setting up the adjustment initial value, StArt:
Default: 0
The initial value, which is loaded by start or pushing [▲] [▼] at the same time, is adjusted from
the smallest to the highest digit with [▲] [▼] and confirmed digit per digit with [P]. A minus sign
can only be para-meterized on the leftmost digit. After the last digit the display changes back
into menu level.

Parameterisation level
Setting up the increments, Step:
Default: 1
The increments for the adjustment types F.tast and E.Tast are adjusted from the smallest to the
highest digit with [▲] [▼] and confirmed digit per digit with [P]. After the last digit the display
changes back into menu level. Per keystroke the setpoint is changed by the increment, which
can be selected from 1…99999.
Maximum possible change acceleration, speed:
Default: pace.i
Via speed the maximum possible change accleration of the setpoint in permanent activation of
up or down can be set. At Pace.1 no multiplication of the increment takes place. For each other
pace-step the maximum speed multiplies tenfold to pace.4 with factor 1000. The change
acceleration is gradually increased at permanent active up or down.
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. The adjusted decimal point has no
influence on the increment and is displayed without additional dependency.
Setting up the switching-on behaviour, reset:
Default: l.star
With this parameter the setpoint behaviour after the switching-on of the device can be selected
by [▲] [▼] and confirmed with [P]. With L.save the last effective setting is taken over as
setpoint during switching-on, the change is taken over after 30 seconds and is then available as
initial value. At L.StAr the defined initial value Start is loaded.
Setting the active input level, In.lev:
Default: louu
The active input level can be adjusted to low or high with [▲] [▼]. With [P] the selection is
confirmed and the display changes back into menu level. This is a very important setting, as it
is used for all operation types type!
Setting the code for the adjustment lock, s.code:
Default: 0000
The code for the adjustment lock is set from the smallest to the highest digit with [▲] [▼] and
confirmed digit per digit with [P]. After the last digit the display changes back into menu level. If
the s.code is set on a value unequal 0000, the code lock is activated for type, F.tast and f.inpu.
This means at each adjustment attempt the enable code s.code is recalled. For type-settings
E.tast the enable code s.code has no meaning.

Selection of analog output, Out.rA:
Default: 0-10
Two output signals are available: 0-10 VDC and 0-20 mA. They can be selected with [▲] [▼]
and are confirmed digit by digit with [P]. The output area can be limited via OUT.En and out.of to
e.g. 4-20 mA.
Setting up the output-final value, Out.En:
Default: 10.000
The output-final value is adjusted from the smallest digit to the highest digit with [▲] [▼] and
digit by digit confirmed with [P]. After the last digit the display changes back into menu level.
Depending on the output signal out.ra, the value relates to a voltage between 0…10 V or a
current between 0…20 mA and is reached, if the adjustment final value END is reached as
setpoint.
Setting up the initial value of the analog output, Out.OF:
Default: 00.000
The output-initial value is adjusted from the smallest digit to the highest digit with [▲] [▼] and
confirmed digit by digit with [P]. After the last digit the device changes back into menu level.
Depending on the output signal out.ra, the value relates to a voltage between 0…10 V or a
current between 0…20 mA and is reached, if the adjustment initial value offs is reached as
setpoint
User code (4-digit number-combination free available), U.CodE:
Default: 0000
With this code (>0000), all parameters are locked, if LOC was selected under menu item run
before. By pushing [P] for approx. 3 seconds during operation mode, the message Code
appears in the display. To get to the reduced parameters that were activated for the user, the
preset U.Code needs to be entered. This code has to be entered before each attempt of
parameterisation, until the A.Code (Master code) activates all parameters again.
Master code (4-digit number-combination free available), A.CodE:
Default: 1234
This code can activate all parameters, after LOC has been activated under menu item run
before. By pushing [P] for approx. 3 seconds during operation mode, the message Code
appears in the display and thus enables the user to reach all parameters by entering the A.codE.
Under run the parameterisation can be activated permanently by selecting ULOC or ProF, thus at
an anew pushing of [P] in operation mode, the code needs not to be entered again.

5.3. Programming interlock
Activation / Deactivation of the programming interlock or completion of the standard
parameterisation with change into menu group level (complete function volume), run:
Default: uloc
Choose between the deactivated key lock Uloc (works setting), the activated key lock Loc, or the
menu group level ProF with the navigation keys [▲] [▼]. Confirm the selection with [P]. After
this, the display confirms the settings with "- - - - -", and automatically switches to operating
mode. If Loc was selected, the keyboard is locked. To get back into the menu level, press [P]
for 3 seconds in operating mode. Now enter the CODE (works setting 1234) that appears using
[▲] [▼] plus [P] to unlock the keyboard. FAIL appears if the input is wrong.
To parameterise further functions, ProF needs to be set. The device confirms this setting with
„- - - - - „ and changes automatically into operation mode. By pressing [P] for approx. 3 seconds
in operation mode, the first menu group InP is shown in the display and thus confirms the
change into the extended parameterisation. It stays as long activated as ULOC is entered in

9. Safety advices
9. Safety advices
Please read the following safety advice and the assembly chapter 1 before installation and keep it for
future reference.
Proper use
The M3-7G-device is designed for the evaluation and display of sensor signals.
Attention! Careless use or improper operation can result in
personal injury and/or cause damage to the equipment.
Control of the device
The panel meters are checked before dispatch and sent out in perfect condition. Should there be any
visible damage, we recommend close examination of the packaging. Please inform the supplier
immediately of any damage.
Installation
The M3-7G-device must be installed by a suitably qualified specialist (e.g. with a qualification in
industrial electronics).
Notes on installation
• There must be no magnetic or electric fields in the vicinity of the device, e.g. due to transformers,
mobile phones or electrostatic discharge.
• The fuse rating of the supply voltage should not exceed a value of 6A N.B. fuse.
• Do not install inductive consumers (relays, solenoid valves etc.) near the device and suppress
any interference with the aid of RC spark extinguishing combinations or free-wheeling diodes.
• Keep input, output and supply lines separate from one another and do not lay them parallel with
each other. Position “go” and “return lines” next to one another. Where possible use twisted pair.
This way, best measuring results can be received.
• Screen off and twist sensor lines. Do not lay current-carrying lines in the vicinity. Connect the
screening on one side on a suitable potential equaliser (normally signal ground).
• The device is not suitable for installation in areas with a risk of explosion.
• Any electrical connection deviating from the connection diagram can endanger human life and/or
can destroy the equipment.
• The terminal area of the device is part of the service. Here, electrostatic discharge needs to be
avoided. Attention! High voltages can cause dangerous body currents.
• Galvanic isolated potentials within one complex need to be placed on an appropriate point (normally
earth or machines ground). So, a lower disturbance sensibility against impacted energy can be
reached and dangerous potentials, that can occur on long lines or due to faulty wiring, can be
avoided.

Error description
Measures
The device shows –LOC– at the attempt
of change.
• The adjustment lock for the setpoint is active,
please check if there is a key-switch.
• The active input signal In.lev has to be adjusted
to HIGH instead of LOW or vice versa.
-LOC2.
By the code recall for the setpoint
appears FAIL or there is an unexpected
code-recall.
CodE
FAIL
• At an unexpected code recall, S.CodE needs to
be set on a value unequal 0000. Check the
parametrisation and set back the parameter.
• If FAIL appears after entering the code, check
the S.CodE in the parameterisation.
3.
The word "HELP " lights up in the
7-segment display.
• The unit has found an error in the configuration
memory. Perform a reset on the default values
and re-configure the unit according to your
application.
4.
The display does not change back to
parametrisation after pressing [P].
• Programming lock is activated
• Enter correct code
5.
"Err1" lights up in the 7-segment
display
• Please contact the manufacturer if errors of this
kind occur.
6.
The device does not react as
expected.
• If you are not sure if the device has been
parameterised before, then follow the steps as
written in chapter 6 and set it back to its
delivery status.
