4. Setting-up of the device
4. Setting up the device
4.1. Switching on
Once the installation is complete, you can start the device by applying the current loop. Check beforehand
once again that all the electrical connections are correct.
Starting sequence
For 1 second during the switching-on process, the segment test (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 start-up sequence, the
device switches to operation/display mode.
4.2. Standard parameterization:
To be able 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
Parameterization level
Selection of the input signal, TYPE:
Default: sens
There are two measuring input options for the current loop: 4-20 mA as works calibration
(without application of the sensor signal) and Sens as sensor calibration (with the sensor
applied). Confirm the selection with [P] and the display switches back to the menu level.
Setting the measuring range end value, END:
Default: 2000
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 Sens was selected as the 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 measuring range start/offset value, offs:
Default: 0400
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 Sens was selected as
the 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 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.
6
4. Setting-up of the device
Menu level
Parameterization level
Setting the display time, SEC:
Default: 01.0
then
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 to 10.0 seconds. Confirm the selection by pressing the [P] button. The
display then switches back to the menu level again.
Activation / deactivation of the programming lock and completion of the standard
parameterization, run:
Default: uloc
With the aid of the [▲] [▼] keys, you can choose between the deactivated key lock Uloc (works
setting) and the activated key lock Loc. Make 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, you must press [P] for 3
seconds in operating mode. You must now enter the CODE (works setting 1 2 3 4) that appears
using the [▲] [▼] keys plus [P] to unlock the keyboard. FAIL appears if the input is wrong.
4.3. Extended parameterization
By pressing the [▲] & [▼] buttons during standard parameterization for one second, the display switches to
the extended parameterization mode.
The operation is the same as in standard parameterization.
Menu level
Parameterization level
Rescaling the measuring input values, EndA:
Default: 20.00
With the aid of this function, you can rescale the input value of 4-20 mA (works setting) without
applying a measuring signal. If sensor calibration has been selected, these parameters are not
available.
Rescaling the measuring input values, OFFA:
Default: 4
With the aid of this function, you can rescale the input value of 4-20 mA (works setting) without
applying a measuring signal. If sensor calibration has been selected, these parameters are not
available.

4. Setting-up of the device
Menu level
Parameterization level
Setting the tare /offset value, tArA:
Default: 0
The given value is added to the linerarized value. In this way, the characteristic line can be
shifted by the selected amount.
Zero point slowdown, ZErO:
Default: 0
With zero point slowdown, a value range around zero can be preselected at which the display
shows zero. If, for example, a 10 is set, the display would show a zero in the range from -10 to
+10 and continue below it with -11 and above it with +11.
4.3.1. MIN/MAX value inquiry - Assignment of key functions, Tast:
Default: no
Here, you can enter for the operating mode either a min/max-value inquiry or a threshold value
correction on the arrow keys.
If the min/max-memory is activated with EHER, the measured min/max-values will be saved
during operation and can be called up via the arrow keys [▲] [▼]. The values are lost if the
device is restarted.
If the threshold value correction LI.1 is selected, the limit values can be changed during
operation without hindering the operating procedure.
With tara the display is tared to zero and is saved permanently as offset. The device confirms
the correct taring by showing 0000 in the display. If No is parameterized, the navigation keys
[▼] [▲] have no function in operating mode.
4.3.2. Flashing of display, FLAS:
Default: no
Here, flashing of the display can be added as an extra alarm function, either to the first limit
value (select: LI-1), the second limit value (select: LI-2) or to both limit values (select: LI-12). With
No (works setting), no flashing is assigned at all.
4.3.3. Limit values / Limits, LI-1:
Default: 0800
For both limit values, two different values can be parameterized. With this, the parameters for
each limit value are called up one after the other.

4. Setting-up of the device
Menu level
Parameterization level
Hysteresis for limit values, HY-1:
Default: 0000
For both limit values, a hysteresis function exists that reacts according to the functional
principle (operating current / quiescent current).
Function if display falls below / exceeds limit value, FU-1:
Default: hi9h
The limit value undercut can be selected with Louu (LOW = lower limit value) and limit value
exceedance can be selected with high (HIGH = upper limit value). If e.g. limit value 1 is on a
switching threshold of 100 and occupied with function high, the alarm will be activated by
reaching the threshold. If the limit value is allocated to Low, an alarm will be activated by
undercut of the threshold.
Limit value /Limits, LI-2:
Default: 1200
For both limit values, two different values can be parameterized. With this, the parameters for
each limit value are called up one after the other.
Hysteresis for limit values, HY-2:
Default: 0000
For both limit values, a hysteresis function exists that reacts according to the functional
principle (operating current / quiescent current).
Function if display falls below / exceeds limit value, FU-2:
Default: hi9h
The limit value undercut can be selected with Louu (LOW = lower limit value) and limit value
exceedance can be selected with high (HIGH = upper limit value). If e.g. limit value 1 is on a
switching threshold of 100 and occupied with function high, the alarm will be activated by
reaching the threshold. If the limit value is allocated to Low, an alarm will be activated by
undercut of the threshold.

4. Setting-up of the device
Menu Level
Parameterization level
Setting the code, CODE:
Default: 1234
With this setting, it is possible to select an individual code (works setting 1 2 3 4) for locking the
keyboard. To locl/release the key, proceed according to menu item run.
4.3.4. Set points - Number of additional set points, SPCt:
Default: 0
In addition to the start and end value, 8 extra set points can be defined to linearize non-linear
sensor values. Only the activated set point parameters are displayed.
Display values for setpoints, dIS1 … dIS8:
Under this parameter the value of the setpoints is defined. With sensor calibration, as with end
value/offset, you will be asked at the end whether a calibration should be made.
Analogue values for setpoints, INP1 … INP8:
The set points are only displayed with the works calibration (4-20 mA) Here, the desired
analogue values can be freely selected. The input of constantly rising analogue values must be
carried out by the customer/user.
4.4. Reset to default values
To return the unit to a defined basic state, a reset can be carried out to the default values.
The following procedure should be used:
• Switch off the power supply
• Press button [P]
• Switch on loop current (approx. 3.8 mA) and press [P]-button until „- - - -“ is shown in the display.
With reset, the default values of the program table are loaded and used for subsequent operation. This puts
the unit back to the state in which it was supplied.
Caution! All application-related data are lost.

7. Safety advices
7. Safety advice
Please read the following safety advice and the assembly chapter 1 before installation and keep it for future
reference.
Proper use
The M1-7S-device is designed for the evaluation and display of current loop signals. With the setpoints, it is
possible to perform simple control tasks (only possible for devices with setpoints).
Danger!
Careless use or improper operation can result in
personal injury and/or 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 M1-7S-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.
• 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. So, you receive best
measuring results.
• 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 where there is 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 devices is part of the service. Here electrostatic discharge needs to be avoided.
Attention! High voltages can cause dangerous body currents.
• Galvanic insulated potentials within one complex need to be placed on a 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.
