2. Inputs
Latch/Reset (Terminal 4)
Static input for display storage. If it is activated
(pnp) with a 4…30 V DC input signal, the cur-
rent measuring value is retained on the display
until this input is released or its signal level
sinks below 2 V DC. The determination of the
minimum and maximum value continues in the
background. If an electrical reset is program-
med for MIN, MAX, or for the Totalizer functi-
on, the function of the input changes to that of
a reset input. It is therefore no longer possible
to perform a Latch.
Current input (Terminal 5)
Analog current measurement input with rever-
se polarity protection and current limitation to
50 mA. The signal line carrying the analog +
signal must be connected here.
To prevent interference signals due
to the power supply, this input is
galvanically isolated. Therefore, the
most negative signal line must be
connected to the analog reference
ground input for measurement.
Analog GND (Terminal 6)
Analog reference input.
If no galvanic separation is required between
the measuring circuit and the supply voltage,
pin 2 or 3 must be connected to this terminal.
Voltage input (Terminal 7)
Analog voltage measurement input.
The signal line carrying the analog + signal
must be connected here. In case of reverse
polarity, this input is protected by a diode.
To prevent interference signals due
to the power supply, this input is
galvanically isolated. Therefore, the
most negative signal line must be
connected to the analog reference
ground input for measurement.
3. Setting of the operating parameters
3.1 Selection of the displayed value and
reset of the minimum, maximum values
and of the totalizer
Pressing the right key allows switching
between the display of the current measured
value, the minimum and maximum value and
the totalizer value, provided these have been
activated during programming.
Press once to display the current function
("Act", "Min", "Max" or "totAL") for 2 seconds.
If the right key is pressed once more during
this period, the current function changes and
"Act", "Min", "Max" or "totAL" is displayed for
about 2 seconds for confirmation. Then, the
value is displayed. If "Min", "Max" or "totAL" is
selected, this value can be erased by pressing
the left red key, provided the reset has been
enabled in the programming menu. If neither
the maximum or minimum value storage nor
the totalizer function has been activated in
the setup, the keys have no function during
operation.

4.12 Total sum counter (totalizer)
Measured value totalizing
switched off
Measured value totalizing
switched on
In case of counter over
or underflow (>99999 or
<-19999), the display flashes
every second.
In case of values >99999,
the counter goes on counting
and looses no value until
reaching the internal counter
value 199999. When the
internal counter value 199999
is reached, no more values
are added. The display goes
on flashing every second, but
the value remains 99999.
In the negative direction,
when it reaches <-19999, the
value stops immediately and
flashes every second.
No leading zero blanking in
case of overflow.
The totalizer adds the cur-
rent measured value every
second. Totalizing only takes
place within the set measu-
ring range (4.1, 4.4, 4.6)
4.13 Totalizer decimal point setting
As for the current measured value, the
decimal point for the display can also be pro-
grammed for the sum (totalizer value). This
has no effect on the display accuracy (only
for display purposes). However, the expected
maximum sum must be taken into conside-
ration.
If, as in example 8.5, the expected sum is
1000, one decimal place should be set at the
maximum.
Factory setting
Sufficiently digits should be reser-
ved for the display of the expected
sum, as the sum stops at 199999
and the measuring result thus gets
lost. If the 5-digit display is not suf-
ficient, the "Factor" (4.14) and the
"Scaler" (4.15) allow adjusting the
sum accordingly.
!
Select the decade with the
left key and set a factor bet-
ween 0.0001 and 9.9999 with
the right key.
4.14 Factor
The displayed totalizer value can be adapted
optimally for the measuring task thanks to the
factor. If for example the current measured
value must be displayed in small units such
as grams, but the result of the sum must be
displayed in kilograms or tons, input the corre-
sponding factor (multiplier):
Note: Factor and scaling only affect
the totalizer.
Total scaling = Factor x Scaling!

english
Page 6 (R60046.0009 - Index 1)
4.15 Scaling
Scaling allows extending the display range
for the totalizer or reducing it for a very fine
setting.
Select the required scale
with the right key: 1 (factory
setting), 0.1, 0.01, 0.001 or
0.0001.
In example 8.6 on page 9
the tank can contain more
than 100,000 l. Scaling 0.01
allows displaying the sum in
hectoliters. As the scaler
(= multiplier) only affects the
sum, the current flow rate is
still displayed in liters/second.
Note: Factor and scaling only affect
the totalizer.
Total scaling = Factor x Scaling!
Electrical reset only. The
reset key is disabled. The
Latch/Reset input operates
as a RESET input. When
actuated, it sets the totalizer
to 0.
Manual reset only. The
Latch/Reset input operates
as a LATCH input. The
current value displayed is
frozen.
4.16 Totalizer reset
There are four possibilities to reset the tota-
lizer. This setting affects the function of the
Latch/Reset input.
4.17 End of programming
The programming routine is
performed once more.
The value set until now can
be checked and modified.
The programming routine
ends and all set values are
taken over as new para-
meters.
The device is then ready for
operation.

8. Examples
8.1 Temperature measurement
A temperature sensor with linear characte-
ristics (in case of non-linear sensors, install
linearizing components upstream) delivers 0 V
at -10°C and 10 V at 80°C. The selected mea-
suring range is 0…10 V. 0 V is the smallest
measured value possible. The display value
-10 is now assigned to this measured value.
Accordingly, 10 V is the largest measured
value. The display value 80 is assigned to this
measured value. The display is now set for the
sensor and can display any intermediate value.
Display value freely positionable
within the measuring range

Page 8 (R60046.0009 - Index 1)
8.2 Filling level measurement
A filling level sensor with linear characteristics
(in case of non-linear sensors, install linea-
rizing components upstream) delivers 4 mA
when a container is empty and 20 mA when it
is full. The value 10 m3must be displayed for
the full container and 0 m3for the empty cont-
ainer. The selected measuring range is
4…20 mA. 4 mA is the smallest measured
value possible. The display value 0 can now
be assigned to this measured value. Accor-
dingly, 20 mA is the largest measured value.
The display value 10 is assigned to this mea-
sured value. The display is now set for the
sensor and can display any intermediate value.
8.3 Removed quantity
Instead of the filling quantity, the value to
display is the removed quantity. The selected
measuring range is again 4…20 mA. A display
value of 10 is now assigned to the smallest
measured value (4 mA) and a display value of
0 is assigned to the largest measured value
(20 mA).
8.4 Filling level measurement with limit
value display
In this third case too, the available quantity
must be displayed ; the container has a
capacity of 10 m3but it can be filled at the
maximum to 8 m3. Moreover, the content shall
not sink below 1 m3. So, for values > 8 m3„Hi“
must be displayed and, for values < 1 m3„Lo“
must be displayed.
The selected measuring range is 4…20 mA.
The display value 0 is assigned to the smallest
input value and 10 is assigned to the largest
input value. In addition, the menu item "Mini-
mum input signal" is used to set the measured
value that corresponds to a content of
1 m3, e.g. 5.6 mA and the menu item "Maxi-
mum input signal" is used to set the measured
value that corresponds to a content of 8 m3,
e.g. 16.8 mA. Therefore, „Hi“ is displayed for
input values > 16.8 mA and „Lo“ for input valu-
es < 5.6 mA.

8.5 Weight measurement with totalizing
The quantity of granulate is to be determined
by means of flow measurement. At full flow
rate (= 10 kg/sec.), the measuring sensor
delivers 20 mA
The selected measuring range is 0…20 mA.
Assign the value 0 to the lowest input signal
and 10 to the highest. To display the sum in
tons, set a factor of 0.001.
The decimal point is only for display
purposes. For a current value dis-
play of 10.0, the totalizer would add
every time 100.
This must be taken into considera-
tion accordingly when setting the
factor.
If the current flow rate is to be dis-
played with one decimal place, set
the factor to 0.0001.
!
8.6 Flow measurement with totalizing
The flowing quantity and the totalized quantity
are to be displayed alternately. The measuring
sensor with linear characteristics (in case
of non-linear sensors, install linearizing
components upstream) delivers 4 mA when
stopped and 20 mA at full flow speed, which
corresponds in this example to 90 l/minute.
Select with "range“ the measuring area 4…20
mA and, for the minimum and maximum input
signal "lo.act" and "hi.act", the respective
factory setting.
Assign the display value 0 to the lowest input
signal "lo.display" and assign the value 1.5
(corresponding to l/second) to the highest input
signal "hi.display".
Set the decimal point for the totalizer "dp.tot"
according to the expected maximum quantity:
for the maximum volume of a 100,000 l bottling
plant, select zero decimal place for the totalizer
and, as this still is not sufficient, use "scaler"
0.01 to increase the display range by two
places, in order to display the totalized quantity
in hectoliters.
Press the right key to switch between the dis-
play of the current value and the display of the
totalizer. Various factors allow displaying the
totalized volume also in other units, e.g. with
factor 2 in 0.5 l bottles or with factor 2.6420
in gallons.
