display will be updated quickly during a 30 second period, after which the update frequency will
slow-down again.
Fig. 3: Example of display information during process.
For the Operator, the following functions are available:
Display level (volume) / height or percentage
This is the main display information of the F073-T. After selecting any other information, it will
always return to this main display automatically.
Level (or volume) is displayed on the upper-line of the display and the percentage, height or
nothing on the bottom line (depending on the configuration settings).
When ------- is displayed, then the value is too high to be displayed. The arrows indicate
the increase/decrease of the level trend.
Programming the level alarm values
Note: This function might not be accessible due to a configuration setting.
When the SELECT key is pressed a few times, following level alarm values are displayed:
low level alarm: enter here 40 USGAL for example,
high level alarm: enter here 600 USGAL for example.
To change the alarm value, the following procedure must be executed:

BRIGHTNESS
(OPTION)
45
The brightness of the backlight can be set in following range:
1 - 5
1is minimum and 5is maximum brightness.
5 - POWER MANAGEMENT
When used with the internal battery option, the user can expect reliable measurement over a long
period of time. The F073-T has several smart power management functions to extend the battery life
time significantly. Two of these functions can be set:
LCD NEW
51 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 - 30 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
52 The unit has two power modes: operate and 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 SELECT twice.

HF073TEN_v0403_05 Atex_IECEx_CSA_FM
Page 16
6 - SENSOR
FILTER
61 The resistive signal of a sensor mirrors the actual level. This signal is
measured several times a second by the F073-T. The value measured is
a "snap-shot" of the real level 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 resistive 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:
FILTER VALUE RESPONSE TIME ON STEP CHANGE OF RESISTIVE VALUE.

75 13 seconds 26 seconds 43 seconds 86 seconds
99 17 seconds 34 seconds 57 seconds 114 seconds
CUT-OFF
62 To ignore e.g. vibration due to an empty tank, a low-level cut-off can be
set as percentage over the full range of 100% signal. When the resistive
value is below required with this setting, the signal will be ignored.
The cut-off value can be programmed in the range 0.0 - 99.9%.
CALIBR. LOW / 0%
63 With this setting it is possible to calibrate the input value for 0% as the
signal from the sensor might not reflect its reference value at level zero.
This function will measure the provided resistance value at level 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

6 - SENSOR (CONTINUED)
CALIBR. HIGH / 100%
64 With this setting it is possible to calibrate the input value for 100% as the
signal from the sensor might not reflect it’s reference value at maximum
level. This function will measure the provided resistance value at
maximum level.
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% value. After pressing enter, CAL SET will be
displayed as soon as the calibration is completed. From
that moment, the resistive value must be more than the
calibrated value for the signal to be processed.
DEFAULT: with this setting, the manufactures value is re-installed.
CAL SET: to select the last calibrated value.

4. INSTALLATION
4.1. GENERAL DIRECTIONS
Mounting, electrical installation, start-up and maintenance of this instrument may only
be carried out by trained personnel authorized by the operator of the facility. Personnel
must read and understand this Operating Manual before carrying out its instructions.
The F073-T may only be operated by personnel who are authorized and trained by the
operator of the facility. All instructions in this manual are to be observed.
Ensure that the measuring system is correctly wired up according to the wiring
diagrams. Protection against accidental contact is no longer assured when the housing
cover is removed or the panel cabinet has been opened (danger from electrical shock).
The housing may only be opened by trained personnel.
Take careful notice of the "Safety rules, instructions and precautionary measures" in
the beginning of this manual.
4.2. INSTALLATION / SURROUNDING CONDITIONS
Take the relevant IP classification of the casing into account (see manufactures plate). Even an IP67
(NEMA 4X) casing should NEVER be exposed to strongly varying (weather) conditions.
When panel-mounted, the unit is IP65 (NEMA 4)!
When used in very cold surroundings or varying climatic conditions, take the necessary precautions
against moisture by placing a dry sachet of silica gel, for example, inside the instrument case.
Mount the F073-T on a solid structure to avoid vibrations.
