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
[O]-key (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 it changes into operating
mode, if no further key operation is done within the next 10 seconds.

4. Setting up the device
Setting up the measuring range start/offset value, offs:
Enter the start/offset value from the smallest to the highest digit with [▲] [▼]and
confirm each digit with [P]. 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.
Setting the measuring range end value, END:
Set the end 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:
There are 3 measuring input options available for known sensor sensibilities: SENS.1 for
1 mV/V, SENS.2 for 2 mV/V and SENS.3 for 3,3 mV/V. Each sensor is measured and
calibrated up to 4 mV/V via SEnS.F. Confirm the selection with [P] and the display
switches back to menu level.

Sonderfunktion [O]-Taste, tASt.4:
For the operation mode, special functions can be deposited on the [O]-Taste. This
function is activated by pressing the key. With tArA the display is tared to zero und
safed permanently as Offset. The device acknowledges the correct taring with oo0oo in
the display. Set.tA switches into the Offset value and can thus be changed via the
navigation keys [▲] and [▼]. EHt.rE deletes the MIN/MAX memory. ActuA shows the
measurand for approx. 7 seconds, then the display changes onto the parametrised
display value. If HOLD has been selected, the moment can be hold constant by pressing
the [O]-key, and is updated by releasing the key. Advice: Hold is activated only, if HOLD
is selected under parameter DISPL. If AbS.UA (Absolute value) was selected, the display
shows the values that have been measured since the voltage has been connected,
without consideration of a previous taring. With t.tAra (temporarily Tara) the Offset is
determined by rising shoulder of the digital input and kept only for the period of the
signal. Via SE.CAL a sensor calibration is done by pushing the zero-key, the flow
diagram is shown in chapter 4.4. At AL-1…AL-8 an output can be set and therewith e.g. a
switch of the metering point can be done. If no is selected, the [O]-key is without any
function in the operation mode.
Setting up the display time, SEC:
The display time is set with [▲] [▼]. The display moves up in increments of 0.1 sec up
to 1 sec and in increments of 1.0 sec up to 10.0 sec. Confirm the selection by pressing
the [P] button. The display then switches back to the menu level again.
Setting the decimal point, dot:
The decimal point on the display can be moved with [▲] [▼] and confirmed with [P].
The display then switches back to the menu level again.

Function for threshold value undercut /exceedance, Fu-1:
A limit value undercut is selected with Louu (for LOW = lower limit value), a limit value
exceedance with High (for HIGH = higher limit value). If e.g. limit value 1 is on a
threshold level of 100 and allocated with function High, an alarm is activated by
reaching of the threshold level. If the threshold value was allocated to Low, an alarm
will be activated by undercutting the threshold value, as long as the hysteresis is zero.
The same applies to LI-1 to LI-2 !
Special function digital input, dIG.In:
The above given parameters can be set for the operation mode onto the optional
digital input aswell. See function description tASt.4.
Threshold values / Limit values, LI-1:
The limit value defines the threshold, that activates/deactivates an alarm.
Hysteresis for Threshold values, HY-1:
The delayed reaction of the alarm is the difference to the threshold value, which is
defined by the hysteresis.

4. Setting up the device
Activation / deactivation of the programming lock or completion of the standard
parameterization with change into menu group level (complete function range),
run:
With the navigation keys [▲] [▼], you can choose between the deactivated key lock
Uloc (works setting) and the activated key lock Loc, or the change into the menu group
level ProF. 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 1 2 3 4) that appears using [▲] [▼]
plus [P] to unlock the keyboard. FAIL appears if the input is wrong. To parameterize
further functions ProF needs to be set. The device confirms this setting with „-----„
and changes automatically in 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 activated as long as ULOC or
LOC is entered in menu group RUN.
Master code (4-digit number-combination, free available), A.CodE:
All parameters can be unlocked with this code, after LOC has been activated under
menu item run. By pressing [P] for 3 seconds in operation mode, the display shows
COde and enables the user to reach all parametes by entering the A.codE. Under run the
parametrisation 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.
User code (4-digit number-combination, free available), U.CodE:
If this code was set (>0000), all parameters are locked for the user, if LOC has been
selected before under menu item run. By pressing [P] for 3 seconds in operation
mode, the display shows COde. The U.Code needs to be entered to get to the reduced
number of parameter sets. The code has to be entered befor each parametrisation,
until the A.Code (Master code) unlocks all parameters again.

parametrised on the highest digit. After the last digit, it can then be chosen between
nOCA and CAL.With nOCA the display value that has been adjusted bevor can now be
taken over, with CAL the matching is done via the measuring section and the analog
input value is taken over. It is always adopted to 100%. With [P] the selection is
confirmed and the device changes back into menu level.
Setting up the measuring range end value End:
The final value has to be adjusted from the smallest to the highest digit with [▲] [▼]
and needs to be confirmed digit per digit with [P]. A minus sign can only be
parametrised on the highest digit. After the last digit, it can then be chosen between
nOCA and CAL.With nOCA the display value that has been adjusted bevor can now be
taken over, with CAL the matching is done via the measuring section and the analog
input value is taken over. It is always adopted to 100%. With [P] the selection is
confirmed and the device changes back into menu level.
Selection of the input signal tYPE:
Available as measuring inputs are SENS.1 for 1 mV/V, SENS.2 for 2 mV/V and SENS.3 for
3.3 mV/V for known sensor sensibilities. Via SEnS.F each sensor is calibrated and
measured up to approx. 4 mV/V. With [P] the selection is confirmed and the device

Assignment (deposit) of key functions, tASt:
For the operation mode, special functions can be deposited on the navigation keys
[▲] [▼], in particular this function is made for devices in housing size 48x24 which do
not have a 4th key ([O] key). If the MIN-/MAX-memory is activated with EHtr, all
measured MIN/MAX-values are safed during operation and can be recalled via the
navigation keys. The values get lost by re-start of the device. If the threshold value
correction LI.12 or LI.34 is choosen, the values of the threshold can be changed during
operation without disturbing the operating procedure. With tArA the device is tared to
zero and safed permanently as Offset. The device confirms the correct taring by
showing ooooo in the display. Set.tA changes into the offset value and can be changed
via the navigation keys [▲] [▼]. The configuration of EHt.rE deletes the MIN/MAX-
memory. Under ActuA the measuand is shown for approx. 7s, after this the display
returns to the parametrised display value. If AbS.UA (Absolute value) was selected, the
display shows the value that has been measured since voltage connection, without
