Page 7
Configuration of the unit
The F190-A is designed for use in many types of applications. For that reason, a setup menu is
available to program the F190-A according to your specific requirements.
The setup includes several important features, such as span, engineering units, signal selection,
power management (to extend battery life-time), etc. All settings are stored in a non-volatile memory
and therefore saved in the event of a power failure or an exhausted battery.
Display information
The unit has a LCD with (optional) backlight to show the process information, status and alarm
messages. The display refresh rate is programmed in the setup menu.
At a key press, the display refresh rate will switch to FAST for 30 seconds. When 'OFF' is selected,
the display goes off after 30 seconds after the last key press. The display temporarily comes on after
a key press.
Options
The following options are available: isolated or active (0)4-20mA / 0-10V analog output, full Modbus
communication RS232/485/TTL (also battery powered), intrinsic safety, mechanical relay or active
output, power- and sensor-supply options, panel mount, wall mount and weather proof enclosures,
flame proof enclosure and LED backlight.
All F190 offer three alarm outputs. A fourth output (R4) is only available with type OS.
R4 may be mentioned in this manual since firmware and general functions are identical for all

This key is used to program and save new values or settings.
The PROG-key is also used to gain access to SETUP-level; please read chapter 3.
SELECT-key
This key is used to SELECT the displayed information, like level and height.
CLEAR-key
This key is used to CLEAR values.
2.3 OPERATOR INFORMATION AND FUNCTIONS
In general, the F190-A will always function at Operator level. The information displayed is dependent
upon the SETUP-settings. The signal from the connected sensor is processed by the F190-A in the
background, whichever screen refresh rate setting is chosen. After pressing a key, the display will be
updated very quickly during a 30 second period, after which it will slow-down again.
Fig. 3: Example of display information during process.
For the Operator, the following functions are available:
▪Display process value / percentage
This is the main display information of the F190-A. After the selection of any other information, it
will always return to this main display automatically. The displayed information depends on the
configuration setting. When "-------" is shown, the value is too high to be displayed.
The arrows indicate the increase/decrease of the level trend.

FW_F190-A_M_v2201-01_EN.docx

SPAN
With the span, the sensor signal is converted to a quantity. The span is
based on the engineering unit (Setup 1.1) and the level at 20 mA (or max
signal). Enter the span with the decimals (set in Setup 1.6). The more
accurate the span, the more accurate the functioning of the system will be.
Example 1: Calculating the Span.
Assume that the sensor generates 20 mA at a pressure of 18.95 bar, the
selected unit is mbar. The span is thus 18,950 mbar. Enter for the span:
"18950" and for the span decimals "0".
Example 2: Calculating the Span.
Assume that the sensor generates 20 mA at a level of 652.31 USGAL, and
the selected unit is ". The span is 652.31.
Enter for the span: "65231" and for the span decimals "2".

DELAY TIME LOW-
LOW
These settings allow an alarm generated by the low-low, low, high and
high-high alarm monitoring functions to be ignored during the set time
period. When the alarm situation still persists after this time, the alarm will
be reflected on the display and outputs as configured.
When the hysteresis mode (SETUP 3.5) is set to disabled, removal of a
previously generated alarm is done immediately.
If the hysteresis mode is set to a mode other than disabled, the delay time
is also used to delay the removal of a previously generated alarm. When
the alarm situation is still absent after this time, the alarm status will be
removed from the display and outputs if applicable.
3.2
DELAY TIME LOW

DELAY TIME HIGH
3.4
DELAY TIME HIGH-

Note: If no hysteresis is required but a delay before removing an alarm is
also needed, this can be achieved by setting the hysteresis mode to either
Balanced or Unbalanced and setting the hysteresis values to zero (0).
3.5
HYSTERESIS
MODE
The hysteresis mode gives the opportunity to separate the alarms setpoint
and reset point from each other. This can prevent fast toggling of alarms
and alarm outputs.
Additionally, when a delay time is set (SETUP 3.1 - 3.4), fluctuations that
would otherwise cause an alarm will also be filtered out.
Hysteresis can also be used to reduce small process actions and combine
them into single larger actions. For example, filling a tank to 80% and then
enabling the pump to empty the tank to 50%, instead of continuously
turning the pump on and off.
The hysteresis mode is selected for all alarms together. The available
hysteresis modes are explained and illustrated in following the table.

FW_F190-A_M_v2201-01_EN.docx
Page 16
MODE
LOW ALARMS
HIGH ALARMS
DISABLED
This mode is used when only simple setpoints are required. An alarm is generated
when the process value reaches the setpoint. The alarm is removed when the process
value passes the setpoint again in the right direction.
In this mode, the delay time is only active when an alarm is set, not when it is reset.
BALANCED
This mode is mostly used for control functions, e.g. a pump. It will allow the process
value to fluctuate within a band set by the hysteresis value, around the entered
setpoint.
When the setpoint is changed, the hysteresis band moves along with it.
In this mode, the delay time is active both when an alarm is set and when it is reset.
UNBALANCED
This mode is usually used for alarm monitoring applications. It causes an alarm to be
generated as soon as the process value reaches the entered setpoint. The alarm will
be removed when the process value changes in the right direction with the value set
for hysteresis.
When the setpoint is changed, the point at which the alarm is removed moves along
with it.
In this mode, the delay time is active both when an alarm is set and when it is reset.
ABSOLUTE
This mode can be used when the application requires independent setpoints and reset
points to be available.
An alarm is generated as soon as the process value reaches the entered setpoint and
the alarm will be removed when the process value crosses the reset point again.
When the setpoint is changed, the reset point remains at the same position; equally,
when the reset point is changed, the setpoint remains at the same position. This is
particularly useful when it is desired to change the setpoint at operator level but the
reset point must remain at the same position.
In this mode, the delay time is active both when an alarm is set and when it is reset.

FORMULA
The F190-A can process the analog input in two ways:
linear interpolated or as square root.
•Interpolation: the signal is processed linear: R = S x I
•Square root: for differential pressure: R = S I
where:
R = The calculated value
S= Span: the maximum value at 20mA. The span is programmed with
setting 1.5.
I = Input: the scaled analog value; in these formulas value 0 (zero) for
(0)4mA and value 1 (one) for 20mA.

FILTER
The analog output signal of a sensor represents the actual process value.
This signal is measured several times a second. The value measured is a
"snap-shot" of the real value as it will be fluctuating.
With the help of this digital filter a stable and accurate reading can be
obtained while the filter level can be set to a desired value.
The filter principle is based on three input values: the filter level (01-99),
the last measured analog value and the last average value. The higher the
filter level, the longer the response time on a value change will be.

initial minimum analog output value is (0) 4mA or 0 V. However, this value
might differ slightly due to ambient influences such as temperature for
example.
Before tuning the signal, make sure that the analog signal is idle (not
used) for any application!
After pressing PROG, the current will be about 4 mA (0 mA or 0 V). The
current can be increased / decreased with the arrow keys and is directly
active. Press ENTER to store the new value.
If required, you can program the analog output 'up-side-down'. The (0)4

OUTPUT RELAY 1
Assign the way outputs R1 R4 behave when an alarm is generated.
The following can be selected:
DEFAULT The output is switched on when an alarm is present and off
when the alarm is removed.
FAIL-SAFE The output is switched on when no alarm is present and off
when the alarm is removed.
This has the advantage that during a power failure, external
systems will detect an alarm since the output cannot be
switched on anymore.
PULSE When an alarm is present, the output toggles on and off with
a frequency of 0.25 Hz (2 seconds on, 2 seconds off). This
allows for a horn to be connected that will blow with an
interval to raise more attention.
When the alarm is removed, the output is turned off.

Clearing the alarm status of the outputs may be allowed in Operator mode. The following settings
enable or disable the clearing of alarms in Operator mode.
Clearing an alarm switches off the related output while the alarm status is still present. The alarm
indication on the display will not be cleared. In case an alarm reoccurs the output will be switched on
again. See Clear Alarm outputs on page 9 for an instruction how to clear alarms in Operator mode.
