5.4 SETUP MENU EXPLANATIONS
5.4.1 MENU 1: DISPLAY
Calculating the Span
The Span is used to convert the sensor signal to a process value. The basis is the selected process
value at 20 mA. Two examples are given.
Example 1. Level measurement with offset 0
● The sensor generates 20 mA at a level of 2,481.3 Liter.
● The level will be displayed using L, with 1 decimal (1.1: DISPLAY > UNIT and 1.3: DISPLAY > DECIMALS).
● Thus, the span is 2481.3.
● Enter the Span as 24813 at 1.5: DISPLAY > SPAN.
Example 2. Level measurement with offset
● The sensor generates 4 mA at a level of 200.00 USGAL, and 20 mA at level 652.31 USGAL.
● The level will be displayed using SGAL, with 2 decimals (1.1: DISPLAY > UNIT and 1.3: DISPLAY >
DECIMALS).
● Thus, the Span is 652.31 – 200 = 452.31 and the Offset is 200.00.
● Enter the Span as 45231 at 1.5: DISPLAY > SPAN and 200 at 1.4: DISPLAY > OFFSET.

for the Span. The following can be selected:
00000 - 1111.1 - 222.22 - 33.333 - 4.4444 - .55555
1.4 OFFSET Sets the actual process value at 4 mA signal. A minus sign can be
entered by pressing the ▲ and ► keys simultaneously.
1.5 SPAN The Span is used to convert the sensor signal to a process value. The
Span is based on the selected measurement unit, decimals and time
unit at maximum signal (20 mA).
Accuracy of the measurement system depends on the accuracy of the
Span.
Examples are given just above this table.
1.6 DIRECTION With setting NORMAL, the displayed value increases with growing input
current. With setting REVERSE, the displayed value decreases with
increasing input current.
1.7 CURRENT Select ON to enable access to displaying the actual input current in mA
in OPERATOR mode (see Section : Process value[»9]).

levels as 0% and 100% in OPERATOR mode (see Section : Process
value[»9]).
1.9 BARGRAPH Enables or disables display of the bargraph. The bargraph (piegraph) is
related to the input signal with the graph at zero at minimum signal and
100% at maximum signal.
5.4.2 MENU 2: SENSOR
2 SENSOR
2.1 FORMULA The F490-A-PL can process the analog signal in two ways: linear or as a
root.
●Interpolation: the signal is processed in a linear way
R = S x I
●Square root: the signal is processed applying a square root
R = S √ I
where R is the process value, S is the maximum value at 20mA
(1.5: DISPLAY > SPAN), and I is the scaled analog input between 0 (for
minimum input, 4 mA) and 1 (for maximum input, i.e. 20mA).

2 SENSOR
2.2 FILTER The analog output signal of a sensor mirrors the actual process value.
This signal is sampled several times per second by the F490-A-PL.
Consequently, random and/or fast changes in sensor signal may lead to
instable displayed process values. With the help of the filter setting a
stable and accurate reading can be obtained. The filter function is based
on three values: the last sampled input signal, the last average value
and the set filter level. The higher the filter level chosen, the slower the
response of the unit to step changes in the process value will be.
The table below gives response times related to filter levels.

2.3 CALIBRATE LOW The F490 is calibrated in factory using a very accurate current source. In
case the sensor signal does not equal 4mA at the offset process value,
this function is needed to set the minimum input current at minimum
level.
Be very sure that the offered tuning signal is stable and correct
before using it for calibration, since this setting has major
influence on the accuracy of the system.
The input loop powered version of the F490-A-PL (Type PL) requires an
input signal of at least 4 mA, not lower.
After pressing PROG, one of three options can be selected.
●CALIBRATE: with this choice, the minimum input will be set at the
actual input current. After pressing ENTER, CAL SET will be
displayed when the calibration process is completed. From now on,
the input current must be higher than the newly calibrated value in
order to be processed.
●DEFAULT: re-installs the factory calibration.
●CAL SET: selects the latest calibrated value.
2.4 CALIBRATE HIGH The unit is calibrated in factory using a very accurate current source. In
case the sensor signal does not equal 20mA at maximum process value,
this function is needed to set the input current at maximum level (offset
+ span).
Be very sure that the offered tuning signal is stable and correct
before using it for calibration, since this setting has major
influence on the accuracy of the system.
After pressing PROG, one of three options can be selected.
●CALIBRATE: with this choice, the maximum input will be set at the
actual input current. After pressing ENTER, CAL SET will be
displayed when the calibration process is completed. From now on,
the input current must be lower than the newly calibrated value in
order to be processed.
●DEFAULT: re-installs the factory calibration.
●CAL SET: selects the latest calibrated value.

6.2.2 OPENING, ASSEMBLING AND CLOSING THE F-SERIES
Panel mount versions (Type HB or HC) do not have a back cover. When removed from their
mounting panel the connectors are readily accessible.
Opening the unit
To open the F-Series enclosure, the front cover needs to be removed. Please follow this procedure.
1. If necessary, clean the enclosure with an anti-static
cloth made damp with a mild soap solution. Wait for
the enclosure to dry before opening.
2. While loosening the screws, hold on to the front cover
to prevent it from falling down.
3. Unscrew all 4 screws from the front of the enclosure
and (if present) mind that the serrated washers are
kept with the screws.
4. Carefully take the front cover away from the rear
cover, minding that the wiring stays intact.
5. Depending on the work to be done, all terminal
connectors can be removed from their mating parts
and the front cover is now completely separate.
Closing / replacing the cover
1. Re-insert all terminals to their original position.
2. Carefully position the front cover onto the back cover,
making sure that the gasket falls nicely into the gutter of
the back cover.
3. Place all 4 screws into the front cover and mind that the
serrated washers are replaced (metal enclosure only).
4. Fasten all 4 screws in an alternating way so that the front
cover is placed evenly across the edge of the back cover.
5. Tighten the 4 screws with the torque value for the type of
enclosure as specified in following table
Plastic enclosure 1 Nm
Aluminum enclosure 1 Nm
Stainless steel enclosure 2 Nm
