always return to this main display automatically.
Temperature is displayed on the upper-line of the display and the measuring unit on the
bottom line.
When "-------" is shown, then the value is too high to be displayed.
Pie graph indication
This 10 segment Pie graph gives a quick impression about the actual value in relation to its
measuring range in a scale of 0-100%.
Low-battery alarm
When the battery voltage drops, it must be replaced. At first "low-battery" will flash, but as
soon as it is displayed continuously, the battery MUST be replaced shortly after!
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 up to some weeks.

3.2.3. EXPLANATION OF SETUP-FUNCTIONS
1 - TEMPERATURE
MEASUREMENT UNIT
11 SETUP - 11 determines the measurement unit for the displayed
temperature. The following units can be selected:
°C - °F - K - _ (no unit).
Alteration of the measurement unit will have consequences for operator
and SETUP-level values.
Please note that the Span has to be adapted as well; the calculation is not
done automatically.
DECIMALS
12 This setting determines for temperature the number of digits following the
decimal point. The following can be selected:
00000 - 1111.1 - 222.22 - 33.333
SPAN
13 With the span, the sensor signal is converted to a temperature.
The span for temperature is determined on the basis of the measuring
range of the sensor.
The more accurate the span, the more accurate the functioning of the
system will be.
Example Calculating the span for temperature
Let us assume that the sensor generates the minimum
signal (e.g.0V) at a temperature of -100.0°C and the
maximum signal (e.g. 10V) is generated at 250.0 °C.
Than the span is 350.0°. Enter for SETUP - 13: "0350.0"
OFF SET
14 The indicator needs to know the measured temperature at minimum
signal. In the above example "-100.0°C".
The minus for a negative temperature can selected by pressing the
center and right button simultaneously.

HF040UEN_v0403_03 Atex_IECEx_CSA_FM
Page 12
2 - DISPLAY
BARGRAPH
21 The bar graph (pie graph) displayed at operator level is percentage-wise
related to the input signal: minimum signal is 0% (setup 43) and maximum
signal is 100% (setup 44).
With this function, the bar graph can be enabled / disabled.
Following selections are available:
OFF - ON
The functions below will only effect the optional LED-backlight.
BACKLIGHT

If a LED backlight has been supplied, the color can be selected.
Following selections are available:
OFF - GREEN - AMBER
BRIGHTNESS
(OPTION)
23
The density of the backlight can be set in following range:
1-5
One is minimum and five is maximum brightness.
3 - POWER MANAGEMENT
When used with the internal battery option, the user can expect reliable measurement over a long
period of time. The F040-U has several smart power management functions to extend the battery life
time significantly. Two of these functions can be set:
LCD NEW
31 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 input signal will be
processed and the output signal will be generated in the normal way.
The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - off.
Example battery life-time:
battery life-time with a FAST update: about 3 years.
battery life-time with a 1 sec update: about 5 years.
Note: after a button has been pressed by the operator - the display
refresh rate will always switch to FAST for 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
32 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 sensor 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.

HF040UEN_v0403_03 Atex_IECEx_CSA_FM
Page 13
4 - SENSOR
FILTER
41 The analog output signal of a sensor does mirror the actual temperature.
This signal is measured several times a second by the F040-U. The value
measured is a "snap-shot" of the real temperature as it will be fluctuating.
With the help of this digital filter a stable and accurate reading can be
obtained while the filter temperature can be set to a desired value.
The filter principal is based on three input values: the filter temperature
(01-99), the last measured analog value and the last average value. The
higher the filter value, the longer the response time on a value change will
be. Below, several filter levels with their response times are indicated:
FILTER VALUE RESPONSE TIME ON STEP CHANGE OF ANALOG VALUE IN SECONDS
50%INFLUENCE 75% INFLUENCE 90%INFLUENCE 99%INFLUENCE
01 filter disabled filter disabled filter disabled filter disabled
02 0.3 seconds 0.5 seconds 1.0 seconds 1.8 seconds

75 13 seconds 26 seconds 43 seconds 86 seconds
99 17 seconds 34 seconds 57 seconds 114 seconds
CUT-OFF
42 To ignore e.g. temperature drift, a low-level cut-off can be set as
percentage over the full range of 10V. 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%.
Examples:
SPAN
(setup 13) REQUIRED CUT-OFF CUT-OFF (setup 42) REQUIRED OUTPUT
450 °C 25 °C 25/450 x 100%=5.5% 10V x 5.5% = 0.55V
TUNE MIN / 0V
43 With this setting it is possible to calibrate the input value for 0V as the
signal from the flowmeter might not be exact 0.0V at flowrate zero.
This function will measure the real output value at flow zero.
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 "0V" 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.
FACT.: with this setting, the factory value is re-installed.
CAL SET: to select the last calibrated value.

4.4. INSTALLING THE HARDWARE
4.4.1. INTRODUCTION
Electro static discharge does inflict irreparable damage to electronics! Before installing
or opening the unit, the installer has to discharge himself by touching a well-grounded
object.
This unit must be installed in accordance with the EMC guidelines (Electro Magnetic
Compatibility).
Do ground the aluminum casing properly as indicated, if the F040-U has been supplied
with the 115-230V AC power-supply type PM. The green / yellow wire between the back-
casing and removable terminal-block may never be removed.
Fig. 7: Grounding aluminum enclosure with option PM 115-230V AC.
FOR INSTALLATION, PAY EMPHATIC ATTENTION TO:
Separate cable glands with effective IP67 (NEMA4X) seals for all wires.
Unused cable entries: ensure that you fit IP67 (NEMA4X) plugs to maintain rating.
A reliable ground connection for both the sensor, and if applicable, for the metal casing. (above)
An effective screened cable for the input signal, and grounding of it’s screen to the “┴“ terminal
or at the sensor itself, whichever is appropriate to the application.

Terminal 4-5: POWER SUPPLY UNIT - TYPE PD / PX:
To power the unit an internal battery can be used (type PB) and / or an external DC power supply
of 8-30V DC (type PX) or 16-30V DC (type PD).
Connect the "-" to terminal 4 and the "+" to terminal 5. When power is applied to these terminals, the
optional internal battery will be disabled / enabled automatically to extend the battery life time.
The input loop powered model - type F040-U-PL - does not have this power supply option.
Terminal 6: sensor supply voltage - type PD.
With this option, a sensor supply terminal comes available which offers the same voltage as
connected to terminal 5 (internally linked).
Remark: this terminal is only available if option PD has been ordered.
Terminal 9-10: power supply backlight - type ZB (option):
To power the backlight, a voltage in the range 20-30V DC has to be connected.
Maximum current 30mA. Connect the "-" to terminal 9 and the "+" to terminal 10.
