Page 9
For the Operator, the following functions are available:
▪Display process value / percentage
This is the main display information of the F190-A. After selecting 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 trend.
▪Programming the high / low alarm values
Remark: this function might not be accessible: it depends on the configuration of the unit. The
alarm value is related to the process value or percentage (depends on configuration setting).
When the SELECT-key is pressed a few times, the alarm values for low and high will be
displayed. To change the alarm value, following procedure must be execute:
1) press PROG: the word "PROGRAM" will be flashing,
2) use to select the digits and to change the blinking digit,
3) set the new alarm value by pressing the PROG/ENTER key.
When data is altered but PROG/ENTER has not been pressed yet, then the alteration can
still be cancelled by waiting for 20 seconds or by pressing PROG/ENTER for a few seconds:
the former value will be reinstated.
▪Alarm
When the actual value is outside the allowed range, an alarm message will be displayed at
the bottom line of the display indicating the type of alarm: LO-LO ALARM, LO ALARM,
HI ALARM or HI-HI ALARM.
The alarm is terminated automatically as soon as the process value is in its range again. Due
to the setup configuration it might be that the process value is outside its range without an
immediate alarm.
▪Low-battery alarm
When the battery voltage drops, it must be replaced.
Only original batteries supplied by the manufacturer may be used, else the guarantee and
liability will be terminated. The remaining lifetime after the first moment of indication is
generally several days.

3.2.6. EXPLANATION OF SETUP MENU 4 –POWER MANAGEMENT
When used with the internal battery option (type PB / PC), the user may hold the concern of reliable
measurement over a long period of time. The F190-A has several smart power management
functions to extend the battery life time significantly. Two of these functions can be set:
LCD NEW
4.1
The calculation of the display-information influences the power
consumption significantly. When the application does not require a fast
display update, it is strongly advised to select a slow refresh-rate.
Please understand that NO information will be lost; the signal will be
processed and the output-signals will be generated in the normal way.
The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - 30 sec - off.
Example 3: Battery life-time
battery life-time with FAST update: about 1 years.
battery life-time with 1 sec update: about 3 years.
Note: after a button has been pressed by the operator - the display
refresh-rate will always be FAST during 30 seconds. When "OFF" is
selected, the display will be switched-off after 30 seconds and will be
switched-on as soon as a button has been pressed.
BATTERY-MODE
4.2
The unit has two modes: operational or shelf.
After "shelf" has been selected, the unit can be stored for several years; it
will not process the signal, the display is switched-off but all settings are
stored. In this mode, power consumption is extremely low.
To wake-up the unit again; press the SELECT-key twice.
3.2.7. EXPLANATION OF SETUP MENU 5 –SENSOR
FORMULA
5.1
The F190-A can process the (0)4-20mA signal in two ways:
Interpolation or 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
5.2
The analog output signal of a sensor represents the actual process value.
This signal is measured several times a second by the F190-A. The
process 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 principal 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.
Below, several filter levels with their response times are indicated:

CUT-OFF
5.2
To ignore e.g. vibration, a low-level cut-off can be set as percentage over
the full range of 16mA (or 20mA). When the analog value is less than
required with this setting, the signal will be ignored.
The cut-off value can be programmed is the range 0.0 - 99.9%.
Example:
SPAN
(setup 1.5)
REQUIRED
CUT-OFF
CUT-OFF
(setup 5.2)
REQUIRED OUTPUT
450 L
25 L
25/450 x 100%=5.5%
16mA x 5.5% + 4mA = 4.88mA
TUNE MIN / 4MA
5.3
With this setting it is possible to calibrate the input value for (0)4mA as the
signal from the sensor might not be exact 4.0 mA (or 0.0 mA) at minimum
signal. This function will measure the real output value at minimum signal.
▪Warning: be very sure that the offered signal is correct
before the calibration is executed as this function has
major influences on the accuracy of the system!
After pressing PROG, three settings can be selected:
▪CALIBRATE: with this setting, the input will be calibrated with the
actual "(0)4mA" value. After pressing enter, CAL SET will be
displayed as soon as the calibration is completed. From that moment,
the analog value must be more than the calibrated value before the
signal will be processed.
▪DEFAULT: with this setting, the manufactures value is re-installed.
▪CAL SET: to select the last calibrated value.
TUNE MAX / 20MA
5.4
With this setting it is possible to calibrate the input value for 20mA as the
signal from the sensor might not be exact 20.0 mA at maximum signal.
This function will measure the real output value at maximum signal.
▪Warning: be very sure that the offered signal is correct
before the calibration is executed as this function has
major influences on the accuracy of the system!
After pressing PROG, three settings can be selected:
▪CALIBRATE: with this setting, the input will be calibrated with the
actual "20mA" value. After pressing enter, CAL SET will be displayed
as soon as the calibration is completed. From that moment, the
analog value must be less than the calibrated value for a reliable
measurement.
▪DEFAULT: with this setting, the manufactures value is re-installed.
▪CAL SET: to select the last calibrated value.
3.2.8. EXPLANATION OF SETUP MENU 6 –ANALOG OUTPUT

TUNE MIN / 4MA
6.6
The initial minimum analog output value is 0/4mA or 0V. However, this
value might differ slightly due to external influences such as temperature
for example. The 0/4mA or 0V value can be tuned precisely with this
setting.
▪Before tuning the signal, be sure that the analog signal is not
being used for any application!
After pressing PROG, the current will be about 4mA (or 0mA / 0V). The
current can be increased / decreased with the arrow-keys and is directly
active. Press ENTER to store the new value.
Remark: the analog output value can be programmed “up-side-down” if
desired, so 20mA at minimum process value for example!
TUNE MAX / 20MA
6.7
The initial maximum analog output value is 20mA (or 10V). However, this
value might differ slightly due to external influences such as temperature
for example. The 20mA value (or 10V) can be tuned precisely with this
setting.
▪Before tuning the signal, be sure that the analog signal is not

Remark: the analog output value can be programmed “up-side-down” if
desired, so 4mA at maximum process value for example!
FILTER
6.8
This function is used to stabilize the analog output signal.
The output value is update eight times per second. With the help of this
digital filter a more stable but less actual reading can be obtained.
The filter principal is based on three input values: the filter level (01-99),
the last analog output value and the last average value. The higher the
filter level, the longer the response time on a value change will be.
