2.3. OPERATOR INFORMATION AND FUNCTIONS
In general, the F010-P will always function at Operator level. The information displayed is dependant
upon the SETUP-settings. All pulses generated by the connected flowmeter are measured by the
F010-P 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 flowrate
This is the main display information of the F010-P. After selecting any other information, it will
always return to this main display automatically.
When "-------" is shown, then the flowrate value is too high to be displayed.
Piegraph indication
This 10 segment Piegraph gives a quick impression about the actual value in relation to its
measuring range in a scale of 0-100%.
As soon as the input value is 5% above the calibrated measurement range, the piegraph
starts flashing.
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.
Fig. 4: Example of low-battery alarm.
Range error
As soon as the input value is 5% outside the calibrated measurement range, the piegraph
starts flashing. Meanwhile, LO RANGE or HI RANGE will be displayed.

SCROLLING THROUGH SETUP-LEVEL
Selection of function-group and function:
SETUP is divided into several function groups and functions.
Each function has a unique number, which is displayed below the word "SETUP" at the bottom of
the display. The number is a combination of two figures. The first figure indicates the function-group
and the second figure the sub-function. Additionally, each function is expressed with a keyword.
After selecting a sub-function, the next main function is selected by scrolling through all "active" sub-
functions (e.g. 1, 11, 12, 13, 14, 1, 2, 3, 31 etc.). The “CLEAR” button can be used
to jump a step back if you missed the desired function.

3.2.3. EXPLANATION OF SETUP-FUNCTIONS
1 - FLOWRATE
MEASUREMENT UNIT
11 SETUP - 11 determines the measurement unit for flowrate.
The following units can be selected:
mL - L - m3 - mg - g - kg - ton - GAL - bbl - lb - cf - REV - no unit -
scf - Nm3 - NL - P.
Alteration of the measurement unit will have consequences for operator
and SETUP-level values. Please note that the K-Factor has to be adapted
as well; the calculation is not done automatically.
TIME UNIT
12 The flowrate can be calculated per second (SEC), minute (MIN), hour
(HR) or day (DAY).
DECIMALS
13 This setting determines for flowrate the number of digits following the
decimal point. The following can be selected:
00000 - 1111.1 - 222.22 - 333.333 - 4.4444 - .55555
K-FACTOR
14 With the K-factor, the flowmeter pulse signal is converted to a flowrate.
The K-factor is based on the number of pulses generated by the
flowmeter per selected measurement unit (SETUP 11), for example per
liter. The more accurate the K-factor, the more accurate the functioning of
the system will be.
Example 1: Calculating the K-factor.
Let us assume that the flowmeter generates 2.4813 pulses per
liter and the selected unit is "cubic meters / m3". A cubic meter
consists of 1000 parts of one liter which implies 2,481.3 pulses
per m3. So, the K-factor is 2,481.3. Enter for SETUP - 14:
"24813" and for SETUP - 15 - decimals K-factor "1".
Example 2: Calculating the K-factor.
Let us assume that the flowmeter generates 6.5231 pulses per
gallon and the selected measurement unit is gallons. So, the K-
Factor is 6.5231. Enter for SETUP - 14: "65231" and for
SETUP - 15 decimals K-factor "4".
DECIMALS K-FACTOR
15 This setting determines the number of decimals for the K-factor
(SETUP 14). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5
Please note that this SETUP - influences the accuracy of the K-factor
indirectly. This setting has NO influence on the displayed number of digits
for "flowrate" (SETUP 13)!
CALCULATION
16 The flowrate is calculated by measuring the time between a number of
pulses, for example 10 pulses. The more pulses the more accurate the
flowrate will be. The maximum value is 255 pulses.
Note: the lower the number of pulses, the higher the power consumption
of the unit will be (important for battery powered applications).
Note: for low frequency applications (below 10Hz): do not program more
than 10 pulses else the update time will be very slow.
Note: for high frequency application (above 1kHz) do program a value of
100 or more pulses.
CUT-OFF TIME
17 With this setting, you determine a minimum flow requirement thresh-hold,
if during this time less than XXX-pulses (SETUP 26) are generated, the
flowrate will be displayed as zero.
The cut-off time has to be entered in seconds - maximum time is 999.9
seconds.
GRAPH. MAX.
18 The piegraph gives the Operator an indication of the flowmeter output
value in relation to its measuring range. Enter with this setting, the
maximum flowrate at which value the piegraph will indicate 100%.

HF010PEN_v0403_03 Atex_IECEx_CSA_FM
Page 13
2 - DISPLAY
BARGRAPH
21 The bargraph (piegraph) displayed at operator level is percentage-wise
related to the input signal: minimum signal is 0% and maximum signal is
100% (setup 18).
With this function, the bargraph can be enabled / disabled.
Following selections are available:
OFF - ON
The functions below will only effect the optional LED-backlight.

(OPTION)
22
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 F010-P 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:
life-time with a coil pick-up, 1kHz. pulses and FAST update: about 2 years.
life-time with a coil pick-up, 1kHz. pulses and 1sec 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.

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 F010-P 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.

4.4.2. TERMINAL CONNECTORS WITH POWER SUPPLY - TYPE : PB / PD / PL / PX
For Intrinsically Safe applications: read chapter 5.
The following terminal connectors are available:
Fig. 8: Overview of terminal connectors F010-P-(PB / PD / PX) and options.
SENSOR SUPPLY
Type PB / PD / PX - terminal 3: sensor supply 1.2V, 3.2V:
Terminal 3 provides a limited supply voltage of 3.2 V DC (coil signals 1.2V) for the signal output of
the flowmeter.
Note: This voltage MAY NOT be used to power the flowmeters electronics, converters etc, as it will
not provide adequate sustained power ! All energy used by the flowmeters pick-up will directly
influence the battery life-time (type PB). It is strongly advised to use a "zero power" pickup such as a
coil or reed-switch when operating without external power. It is possible to use some low power NPN
or PNP output signals, but the battery life time will be significantly reduced (consult your distributor).
Type PD - terminal 6: sensor supply 8.2V:
With this option, a basic but real sensor supply of max. [email protected] is available to power e.g. a
Namur sensor.

REMARKS: TERMINAL CONNECTORS:
Terminals 1-3; Flowmeter input:
Three basic types of flowmeter signals can be connected to the unit: pulse, active pulse or coil. The
screen of the signal wire must be connected to the common ground terminal
The input signal type has to be selected with the correct SETUP-function (read par. 3.2.3.)
Coil-signal:
The F010-P is suitable for use with flowmeters which have a coil output signal.
Two sensitivity levels can be selected with the SETUP-function:
COIL LO: sensitivity from about 90mVp-p.
COIL HI: sensitivity from about 20mVp-p.
Type ZF (option): offers for setting COIL HI : sensitivity from about 10mVp-p.
Type ZG (option): offers for setting COIL HI : sensitivity from about 5mVp-p.
Pulse-signal NPN / NPN-LP:
The F010-P is suitable for use with flowmeters which have a NPN output signal. For reliable pulse
detection, the pulse amplitude has to go below 1.2V. Signal setting NPN-LP employs a low-pass
signal noise filter, which limits the maximum input frequency - read par. 3.2.3.
