3. 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:
Parameters 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 changes into operating
mode, if no further key operation is done within the next 10 seconds.

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 parameterisation,
until the A.Code (Master code) unlocks all parameters again.
ThesameappliestoLI-1 to LI-2 !
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.
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.
Hysteresis for limit values, HY-1:
The delayed reaction of the alarm is the difference to the threshold value, which is
defined by the hysteresis.

Display overflow, dI.OUE:
With this function the display overflow (_ _ _ _ _) can be defined on a definite value.
Device undercut, dI.Und:
With this function the device undercut (_ _ _ _ _) can be defined on a definite value.
Exception is input type 4-20 mA, it already shows undercut at a signal <1 mA, so a
sensor failure is marked.
Analog values for setpoints, InP.01 … InP.30:
The setpoints are allways set according to the selected input signal. The desired
analog values can be freely parameterised in ascending order.
Back to menu group level, rEt:
With [P] the selection is confirmed and the device changes into menu group
level „–INP-“.
Display values for setpoints, dIS.01 … dIS.30:

Arithmetic, ArItH:
With this function the calculated value, not the measuring value, is shown in the
display. With no, no calulation is deposited. With [P] the selection is confirmed and the
device changes into menu level.
Rounding of display values, round:
This function is for instable display values, where the display value is changed in
increments of 1-, 5-, 10- or 50. This does not affect the resolution of the optional
outputs. With [P] the selection is confirmed and the device changes into menu level.
Sliding average determination, AVG:
Here, the number of the meterings that need to be averaged is preset. The time of
averaging results of the product of measuring time SEC and the averaged metering AVG.
With the selection of AVG in the menu level DISPL, the result will be shown in the display
and evaluated via the alarms.
Display time, DISEC:
The display is set up with [▲] [▼]. Thereby it jumps until 1 second in increments of 0.1
seconds and until 10.0 seconds in increments of 1.0. With [P] the selection is

Display flashing, FLASH:
A display flashing can be added as additional alarm function either to single or to a
combination of off-limit condition. With no, no flashing is allocated.
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/nax-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 switches into the offset value and can be changed
via the navigation keys [▲] [▼].
Display, dISPL:
With this function the current measuring value, min-/max-value, totaliser value or the
process-controlled hold-value can be allocated to the display. With [P] the selection is
confirmed and the device changes into menu level.
Zero point slowdown, ZErO:
At the zero point slowdown, a value range around the zero point can be preset, so the
display shows a zero. If e.g. a 10 is set, the display would show a zero in the value
range from -10 to +10; below continue with -11 and beyond with +11. The maximum
adjustable range of value is 99.

Special function [O]-key, 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 device is set temporarily on a
parameterised value. The device acknowledges the correct taring with oo0oo in the
display. Set.tA adds a defined value on to the currently displayed value. Via totAL the
current value of the totaliser can be displayed for approx. 7 seconds, after this the
device switches back on the parameterised display value. If tot.rE is deposited, the
totaliser can be set back by pressing of the navigation keys [▲] [▼], the device
acknowledges this with ooooo in the display. EHt.rE deletes the min/max-memory. 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. ActuA shows the measuring value for approx. 7 seconds, after
this the device switches back on the parametrised display value. The same goes for
AVG, here the sliding average values will be displayed. At AL-1…AL-4 an output can be
set and therewith e.g. a setpoint adjustment can be done. If no is selected, the [O]-key
is without any function in the operation mode.
Assignment (deposit) of key functions, tASt :
Via totAL the current value of the totaliser can be displayed for approx.7 seconds, after
this the device changes back on the parameterised display value. If tot.rE is
deposited, the totaliser can be set back by pressing of the navigation keys [▲] [▼],
the device acknowledges this with ooooo in the display. The configuration of EHt.rE
deletes the MIN/MAX-memory. Under ActuA the measurand is shown for approx.
7 seconds, after this the display returns to the parameterised display value. If AbS.UA
(absolute value) was selected, the display shows the value that has been measured
since voltage connection, without consideration of a previous taring. If no is selected,
the navigation keys are without any function in the operation mode.
