1. INTRODUCTION

1.1. SYSTEM DESCRIPTION

Functions and features

The batch controller model F131-P is a microprocessor driven instrument designed for batching and

filling of small up to large quantities as well as displaying the flow rate, the batched total and the

accumulated total.

This product has been designed with a focus on:

▪ultra-low power consumption to allow long-life battery powered applications (type PB/PC);

▪intrinsic safety for use in hazardous applications (type XI),

▪ability to process all types of flowmeter signals;

▪transmitting possibilities with analog, pulse and communication outputs;

▪several mounting possibilities with GRP or aluminum enclosures for industrial surroundings.

Flowmeter input

This manual describes the unit with a pulse input from the flowmeter. Other versions are available to

process (0)4-20mA signals.

One flowmeter with a passive or active pulse, Namur or sine wave (coil) signal output can be

connected to the F131-P. To power the sensor, several options are available.

Standard outputs

▪Two passive transistor or relay outputs: for two- or one stage control with pulse output.

▪Pulse output to transmit a pulse that represents a totalized quantity as programmed.

▪Linear (0)4-20mA or 0-10V analog output to represent the actual flow rate as programmed. The

(0)4-20mA or 0-10V signal limits can be tuned.

Fig. 1: Typical application

FW_F131P_v1702_02_EN.docx

Page 7

Configuration of the unit

The F131-P is designed for use in many types of applications. For that reason, a setup menu is

available to program the F131-P according to your specific requirements.

The setup includes several important features, such as K-Factors, engineering units, signal

selection, power management (to extend battery life-time), etc. All settings are stored in a non-

volatile memory and therefore kept 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.

A backup of the total and accumulated total in EEPROM memory is made every minute.

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.

2. OPERATIONAL

•This device may only be operated by persons who are authorized and trained by the

operator of the facility. All instructions in this manual are to be observed.

•Take careful notice of the "Safety rules, instructions and precautionary measures" in the

front of this manual.

This chapter describes the daily use of the F131-P . This instruction is meant for users / operators.

2.1. CONTROL PANEL

The control panel has three keys. The available keys are:

Fig. 2: Control Panel

Functions of the keys

This key is used to program and save new values or settings.

The PROG/ENTER key is also used to gain access to the setup menu (read

chapter 3).

This key is used to START the batch process.

The START/key is also used to increase a value after the PROG/ENTER key has

been pressed (read chapter 3).

This key is used to pause or stop the batch process. When the batch process is

stopped, it cannot be continued. The STOP/key is also used to select the total and

the accumulated total.

The STOP/key is also used to select a digit or an option after the PROG/ENTER

key has been pressed (read chapter 3).

2.2. OPERATOR INFORMATION AND FUNCTIONS

In general, the F131-P operates in the operator

mode. The shown information depends on the

settings which are made in the setup menu.

The signal from the connected sensor is processed

by the F131-P in the background, independent from

the selected display refresh rate.

Fig. 3: Process information (typical)

▪To enter a batch quantity (change the preset)

You can only change the preset when the READY

indicator is on.

1. Press the PROG/ENTER key until the

PROGRAM indictor starts to blink.

2. Use the START/and STOP/key to change

the value.

3. Momentarily, press the PROG/ENTER key to

confirm the new preset.

Fig. 4: Program preset value (typical)

If you do not press the PROG/ENTER key to confirm, your selection is not saved.

The PRESET value can be used time after time till a new value is programmed.

Changes are only saved when you press the PROG/ENTER key.

FW_F131P_v1702_02_EN.docx

Page 9

▪Leading zero

The amount of leading zeros is dependent on the batch maximum setting. In the program mode

the leading zeros will show. When you confirm the selection with the PROG/ENTER key, the

F131-P will hide the leading zeros in the operational preset menu.

It is not possible to enter a preset value which exceeds the batch maximum setting.

E.g. if the batch maximum is set to 20000, it will not be possible to program a preset

21000. If you want to program a preset 21000, you must change the batch maximum

setting.

Fig. 5: Leading zero (typical)

▪Batch maximum/minimum

When you program a new value which is not valid, the decrease-sign ▼(batch too big, program

a smaller batch) or the increase-sign ▲ (batch to small, program a bigger batch) will show.

▪To start the batch process

The batch process can only be started when "READY" is shown. The batch process is started

by pressing the START/key. Depending on the SETUP-settings, one or two relays will be

switched. The arrows at the display indicate if the ACTUAL-value is counting up or down.

▪To interrupt or to stop the batch process

When the STOP/key is pressed once, the batch

process is paused; the actual values are not lost. At

the display, the word "PAUSE" blinks. In this case

the, the batch process can be resumed with the

START/key.

When the STOP/key is pressed two times, the

batch process is stopped completely. In this case the

actual values are "lost" and the system returns to

steady state: the batch process cannot be resumed.

Fig. 6: Process paused (typical)

▪Flow rate indication

This function might not be available: it depends on the configuration of the unit.

During batching, the actual flow rate will be shown on the bottom-line of the display.

It depends on the configuration settings if flow rate is shown continuously or alternating with the

preset value.

▪Clear batch total

The value for total can be reset. To do so, select Total and press PROG followed by STOP -

STOP. After pressing the STOP/key once, the flashing text "PUSH STOP" is shown. To

avoid a reset at this stage, press another key than the STOP/key or wait for 20 seconds.

The reset of total DOES NOT influence the accumulated total.

▪Display accumulated total

When the STOP/key is pressed, total and accumulated total are shown. The accumulated

total cannot be reset. The value will count up to 99,999,999,999. The unit and number of

decimals are shown according to the configuration settings for total.

▪Low-battery alarm

Only use original batteries. Original batteries can be ordered at the manufacturer.

The use of unapproved batteries will void the warranty.

•

At the end of the battery’s life-time, the

voltage starts to drop. When the voltage

becomes too low, the battery indicator comes

on. When the battery indicator is on, install a

new and fresh battery as soon as possible.

Fig. 7: Low-battery alarm (typical)

FW_F131P_v1702_02_EN.docx

Page 10

▪No-flow alarm

The F131-P offers a no-flow monitoring feature: When the flowmeter does not generate a signal

during a certain (preset) time period, the F131-P will shut-off the control output(s) and bring the

batch controller in alarm status.

The “PAUSE” and “ALARM” indicators come on and NO FLOW is shown. Press the STOP/key to

confirm the alarm status and note that the “PAUSE” indicator stays on. Now you can cancel or

continue the batch (after you have solved the possible problem).

▪Alarm

When the alarm indicator is shown, refer to Appendix B: Problem Solving.

3.2.1. EXPLANATION OF SETUP MENU 1 - PRESET

UNIT

This setting is used to select the engineering unit for the indication of the

batch total, the accumulated total and the pulse output.

When you change the engineering unit, you must recalculate and

reprogram the K-factor for the (accumulated) total. When you

recalculate and reprogram the K-Factor, the history for

(accumulated) batch total is not correct anymore, because the

(accumulated) batch total is not recalculated. For future reference,

best practice is to make a note of the accumulated total before you

program the recalculated K-Factor.

DECIMALS

This setting is used to set the amount of digits behind the decimal point

for the (accumulated) total indication.

K-FACTOR

This setting is used to set the K-Factor for the total. With the K-Factor, the

flowmeter pulse signals are converted to a quantity. The K-Factor is

based on the number of pulses generated by the flowmeter per selected

engineering unit, for example per m3. A more accurate K-Factor (more

decimals, as set in decimals K-Factor) allows for a more accurate

operation of the system.

Example 1: Calculating the K-Factor.

The flowmeter generates 2.4813 pulses per liter and the selected unit is

m3. A cubic meter consists of 1000 liter which gives 2.4813 pulses*1000

liter=2481.3 pulses per m3. So, the K-Factor is 2481.3. Enter for the

Flowmeter K-Factor: 24813 and for the flowmeter K-Factor decimals: 1.

Example 2: Calculating the K-Factor.

The flowmeter generates 6.5231 pulses per gallon and the selected

engineering unit is gallons. So, the K-Factor is 6.5231. Enter for the

Flowmeter K-Factor: 65231 and for the Flowmeter K-Factor decimals: 4.

When you recalculate and reprogram a new K-Factor, the history for

(accumulated) batch total is not correct anymore, because the

(accumulated) batch total is not recalculated. For future reference,

best practice is to make a note of the accumulated total before you

program the recalculated K-Factor.

DECIMALS K-FACTOR

This setting is used to set the amount of digits behind the decimal point

for the K-Factor.

BATCH MIN

This setting is used to set the lower limit for a batch volume. An operator

cannot set a batch volume which is beyond the lower limit.

BATCH MAX

This setting is used to set the upper limit for a batch volume. An operator

cannot set a batch volume which is beyond the upper limit.

3.2.2. EXPLANATION OF SETUP MENU 2 - FLOW RATE

The settings for total and flow rate are entirely separate. In this way, different engineering units can

be used for each e.g. cubic meters for total and liters for flow rate.

UNIT

This setting is used to select the engineering unit for the indication of the

flow rate.

Alteration of the engineering unit will have consequences for

operator and SETUP-level values, they will not be automatically

recalculated to the value of the new selected unit. The K-factor has

to be adapted as well; the calculation is not done automatically.

TIME

This setting is used to set the time unit for the flow rate calculation. Note

that the flow rate is given in engineering unit/time unit, e.g. liters/minute

(l/min).

When you change this setting, also recalculate and change the

settings for the analog rate-min and analog rate-max.

DECIMALS

This setting is used to set the amount of digits behind the decimal point

for the flow rate indication.

K-FACTOR

This setting is used to set the K-Factor for the flow rate. With the K-

Factor, the flowmeter pulse signals are converted to a quantity. The K-

Factor is based on the number of pulses generated by the flowmeter per

selected engineering unit, for example per m3. A more accurate K-Factor

(more decimals, as set in decimals K-Factor) allows for a more accurate

operation of the system.

DECIMALS K-FACTOR

This setting is used to set the amount of digits behind the decimal point

for the K-Factor.

FW_F131P_v1702_02_EN.docx

Page 15

CALCULATION

The flow rate is calculated by measuring the time between a number of

pulses, for example 10 pulses. The more pulses the more accurate the

flow rate will be. The maximum value is 255 pulses.

This setting does influence the update interval for the flow rate and

thus, indirectly the update interval of the analog output.. (maximum

update 10 times a second). If the output response is too slow, decrease

the number of pulses. For low frequency applications (< 10Hz): do not

program more than 10 pulses, else the update time will be very slow.

For high frequency applications (> 1kHz): do program 50 or more pulses.

CUT-OFF

This setting is used to set the threshold for a minimum flow. If during this

time less than XXX-pulses are generated (refer to Calculation), the flow

rate will be shown as zero. The cut-off has to be entered in seconds.

3.2.3. EXPLANATION OF SETUP MENU 3 - OVERRUN

Due to system parameters which are beyond the settings of the batch controller, an overrun can

occur at the end of a batch. The batch controller analyzes the overrun volume and automatically

corrects the volume each time after each batch (self learning).

OVERRUN

For an accurate overrun correction, it is necessary that the flowmeter

meets certain technical demands, such as "high resolution" and shows no

"false" overrun due to a slow update time. Do not enable this function if

the flow meter is not compatible to this function.

TIME

The overrun characteristic of the system will be analyzed during a certain

time after the batch relay has been de-energized. In this way, false signal

generated through leakage are eliminated. Enter here the expected time

needed by the system to stop a batch. It is advisable to provide extra time

in order to avoid an incorrect overrun correction or false leakage alarms.

The next batch can only be started after the overrun time is completed!

3.2.4. EXPLANATION OF SETUP MENU 4 - ALARM

The F131-P offers a no-flow monitoring feature: When the flowmeter does not generate a signal

during a certain (preset) time period, the F131-P will shut-off the control output(s) and bring the

batch controller in alarm status.

NO-FLOW

This setting is used to program the behavior of the no-flow alarm. When

the flow rate is zero, it is possible to ignore or disable the no-flow

monitoring.

TIME

This setting is used to set a delay time for the related alarm. When the

alarm condition is still valid after the delay time, an alarm is given.

3.2.5. EXPLANATION OF SETUP MENU 5 - DISPLAY

DISPLAY

This setting is used to set the behavior of the counter during a batch

process: count down (quantity to do) or count up (quantity done).

FLOW RATE

This setting is used to determine how the flow rate will be shown during a

batch process. The settings are:

▪off: flow rate will not be shown;

▪batch after the start, the flow rate will be shown till the end of the

batch. (advise: set the display to setting "decrease";

▪toggle: flow rate is shown alternating with the preset value.

LIGHT

The backlight brightness can be adjusted from 0% (off) to 100% (full

brightness) in steps of 20%.

When the F131-P is only loop powered, the backlight is disabled. An

external power supply is required to supply the backlight.

3.2.6. EXPLANATION OF SETUP MENU 6 - POWER MANAGEMENT

When used with the internal battery option (type PB/PC), the user can expect reliable measurement

over a long period of time. The F131-P has several smart power management functions to extend

the battery life time significantly. Two of these functions can be set.

LCD NEW

The calculation of the display-information influences the power

consumption significantly. When the application does not require a fast

display refresh rate, it is strongly advised to select a slow refresh rate.

Please understand that NO information will be lost; every pulse will be

counted and the output signals will be generated in the normal way.

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.

Example battery life-time with a coil pick-up:

•1kHz pulse and FAST update: about 2 years;

•1kHz pulse and 1 sec update: about 5 years.

BATTERY MODE

The F131-P has two modes: operational or shelf.

After "shelf" has been selected, the F131-P can be stored for several

years; it will not process the sensor signal; the display is switched off but

all settings and totals are stored. In this mode, power consumption is

extremely low.

To wake up the F131-P again, press the START/key two times.

3.2.8. EXPLANATION OF SETUP MENU 8 - ANALOG OUTPUT

A linear 4-20mA signal (option AB: 0-20mA or option AU: 0-10V) output signal is generated that

represents the flow rate. The settings for the flow rate influence the analog output directly. The

relationship between the flow rate and the analog output is set with the following settings.

OUTPUT

If the analog output is not used, select disable to minimize the power

consumption (e.g. save battery life-time).

Option AP: When a power supply is available but the output is disabled, a

3.5mA signal will be generated.

RATE-MIN

Enter here the flow rate at which the output should generate the minimum

signal (0)4mA or 0V - in most applications at zero flow. The number of

decimals shown depend upon setup 23. The engineering units/time (e.g.

L/min) are dependent upon setup 21 and 22.

RATE-MAX

Enter here the flow rate at which the output should generate the maximum

signal (20mA or 10V) - in most applications at maximum flow. The number

of decimals shown depend upon setup 23. The engineering units/time

(e.g. L/min) are dependent upon setup 21 and 22.

CUT-OFF

To ignore leakage of the flow for example, a low flow cut-off can be set as

a percentage of the full range of 16mA, 20mA or 10V.

When the flow is less than the required rate, the current will be the

minimum signal (0)4mA or 0V.

Example: Calculate the cut-off.

Rate-min: 0L/min [4mA], Rate-max: 100 L/min [16mA], Cut-off: 2%

Required rate [L/min]: (rate-max - rate-min)*cut-off: (100-0)*2%=2 L/min

Output [mA]: rate-min + (rate-max*cut-off): 4+(16*2%)=4.32mA

TUNE-MIN

The (0)4mA or 0V value can be tuned precisely with this setting. The

initial minimum analog output value is (0)4mA or 0V. However, this value

might differ slightly due to ambient influences such as temperature for

example.

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 (0mA or 0V). 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)4mA or 0V represents the maximum flow rate and the 20mA or 10V

represents the minimum flow rate.

TUNE-MAX

The 20mA or 10V value can be tuned precisely with this setting. The initial

maximum analog output value is 20mA or 10V However, this value might

differ slightly due to ambient influences such as temperature for example.

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 20mA or 10V. 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)4mA or 0V represents the maximum flow rate and the 20mA or 10V

represents the minimum flow rate.

FILTER

This setting is used to stabilize the output signal. With the help of this

digital filter a more stable but less actual representation of the flow rate

can be obtained.

The filter principal is based on three input values: the filter level (01-99),

the last calculated flow rate and the last average value. The higher the

filter level, the longer the response time on a value change will be.

3.2.9. EXPLANATION OF SETUP MENU 9 - RELAYS

Two control outputs are available to control relays or valves. Relay 2 can also be used as pulse

output according the batch total (actual) or accumulated total.

RELAYS

This submenu is used to set the function of related output.

1-Step: The F131-P is used for one-stage batch control while R2 is used

as a scaled pulse output.

2-Step: The F131-P is used for two-stage batch control.

PRECLOSE

According to the setting 91 - 2-step, relay two will be used to control a

second valve for the batch process. If the product is batched in two steps,

the switch-off-moment for relay 2 has to be set. The switch moment is

based on the remaining quantity before the end of batch.

If preclose is set to zero, relay 2 will switch simultaneously with relay 1.

The settings: width, decimals, amount and pulse are only valid when

relay 2 is used as a scaled pulse output. A scaled pulse output is used to

indicate that the batch or accumulated total has increased with the value

as set in the setup 95.

WIDTH

When relay 2 is used as a scaled pulse output:

The pulse width determines the time that the output will be active; in other

words the pulse duration. Value “zero” will disable the pulse output.

The pulse signal always has a 50% duty cycle, hence the minimum time

between the pulses is equal to the pulse width setting. If the frequency

should go out of range –when the flow rate increases for example –an

internal buffer will be used to “store the missed pulses”: As soon as the

flow rate slows down, the buffer will be “emptied”.

It might be that pulses will be missed due to a buffer-overflow, so it is

advised to program this setting within its range!

DECIMALS

This setting is used to set the amount of digits behind the decimal point for the

amount.

AMOUNT

A pulse will be generated every time a certain quantity is added to the

total. Enter this quantity here while taking the decimals for pulse into

account.

PULSE

The pulse generation is controlled by the batch total or the accumulated

total.

When set to “batch”, the buffer (setting: Width) will be emptied when a

new batch is started.
