6.1 Post-installation check and switching on the device

Make sure that all post-connection checks have been carried out before you commission
your device:

• ‘Post-installation check’ checklist in Section 3.5

• ‘Post-connection check’ checklist in Section 4.2

Once the operating voltage is applied, the display lights up and the green LED indicates that
the device is operational.
When you commission the device for the first time, you program the setup in accordance
with the descriptions provided in these Operating Instructions in the following sections.
When commissioning a device already configured or preset, measuring is immediately
started as per the settings. The values of the channels currently activated appear on the
display. Changes to the display can be made in the Display menu item (→ ä 30 ‘Step 7:
Configuring the display functions’).

6.2 General information on the device configuration

You can commission/configure your device locally using the three integrated keys, or by PC.
You require the Commubox FXA291 to connect the device to a PC (see ‘Accessories’ section).

Advantages of configuring the device using FieldCare Device Setup:

• The device data are saved in the FieldCare Device Setup and can be called up at any time.

• Entries can be made more quickly using the keyboard.

6.3 Notes on setup access protection

Access to the setup is enabled when the device leaves the factory. Access can be locked via
the setup.

Proceed as follows to lock the device:

1. Press ‘E’ to get to the configuration menu

2. Press ‘+’ , ‘Setup’ is displayed→ , press ‘E’

3. Press ‘+’ again until ‘System’ is displayed, press → ‘E’

4. ‘Access code’ is displayed, press → ‘E’

5. Set the code: the desired numerical value is configured by pressing the ‘+’ and ‘-’ keys.
The access code is a four-digit number. The corresponding position of the number is
displayed in plain text.
To confirm the value entered and to go to the next position, press ‘E’.

6. Confirm the last position of the code to exit the menu. The code is displayed in full. Press
‘+’ to scroll to the last point of the ‘x Back’ submenu and confirm this point. As a result,
the value is accepted and the user returns to the level of the ‘Setup’ item. Also exit this
submenu via the last ‘x Back’ parameter to get back to the measured value/channel
display.

Remove the protective foil from the display as this restricts display legibility

7. Configure the display functions (→ ä 30)

The following section provides a detailed account of how to set up the two-channel device
and the differential pressure application package (brief overview of the configuration
→ ä 23, only available in the two-channel version). If you want to configure a single-
channel device, please proceed as explained in Section 6.4.2.

6.4.1 Step 1: Selecting the application conditions/number of active

input channels

Application conditions of a two-channel device

Call up the Setup menu after performing the post-installation check.
Press ‘E’ → press ‘+’ → ‘Setup’ is displayed, press → ‘E’.
Select your application conditions in the first point of the setup. The following options are
available:

1. Differential pressure (‘Diff pressure’): application package; parameters are
automatically preconfigured for you.

2. Single channel (‘1-channel’): universal input 2 (‘Analog in 2’) is deactivated (‘off’)
from the software side. The second channel can always be activated at a later stage via
‘Setup’ → ‘Analog in 2’ (→ ä 24).

3. Two channels (‘2-channel’): universal input 1 (‘Analog in 1’) and universal input 2
(‘Analog in 2’) are preconfigured with the following values:
– Signal type (‘Signal type’): ‘Current’
– Signal range (‘Signal range’): ‘4-20mA’

The following section provides a detailed description of the "Differential pressure" application
package.
To set up the device in single-channel/two-channel applications, please proceed with the
device setup as explained in Section 6.4.2 (analog input 1 (‘Analog in 1’)).

If the application or the parameter selected are subsequently changed, parameters
already configured are retained (e.g. if the differential pressure application is
changed to two-channel → ‘Calc value 1’ remains at the Difference parameter).

Differential pressure application

A concise setup is available for differential pressure applications.
Once the differential pressure application setup has been successfully completed, the
configured parameters of the analog inputs and the linearization points are used to
automatically form the difference between the two inputs and linearize the signal. As a
result, the volume is already shown on the display (= calculated value 2).

NOTICE

The following is essential to ensure values are calculated correctly and that the setup
functions properly:

‣ Sensor 1 returning the higher pressure: connected to analog input 1 (‘Analog in 1’)
‣ Sensor 2 returning the lower pressure: connected to analog input 2 (‘Analog in 2’)

Fig. 6: Differential pressure application

Setup → Application → Diff pressure

After selecting the differential pressure application by confirming the "Diff pressure"
parameter, the parameters, which are displayed in succession and can be edited, must be
configured individually for your application.
Some parameters are already configured for you by selecting the application setup
(→ ä 23).
The parameter “CV Factor” serves for the regard of the density of the medium at level
measurement, i.e. it equates the mathematic formula 1/(density*gravitational
acceleration). The standard value of the factor is 1.
At this the density is to be named in kg/m

3

and the pressure in Pascal (Pa) or N/m2. The
gravitational acceleration is defined by the constant on the earth’s surface.
It amounts g=9.81m/s

6.4.2 Step 2: Configuring the universal input(s) (‘AnalogIn 1/2’)

The device has one universal input, and optionally another universal input for current
(‘Current’), voltage (‘Voltage’), resistance thermometer (‘RTD’) or thermocouples (‘TC’).
The input is monitored for a cable open circuit (see "Measuring range limits" table (→ ä 36)
and "Troubleshooting" section (→ ä 39)).

Minimum/maximum values at the inputs:

Each universal input saves the smallest and biggest measured value measured. These values
can be reset individually for every channel. In the setup, the administrator can decide
whether a user can reset the minimum and maximum values of the individual channels
directly in the main menu without the need for a release code. It is reset in the event of a
Reset and if the scaling of the channel is changed.

The current min./max. value is saved every 15 minutes. If the power supply is
disconnected (mains off/mains on), a gap in the recording may result. The
measuring interval starts when the device is switched on. It is not possible to
synchronize the measuring cycles to full hours.
Limit values and relays are available for monitoring the measured values. They
should be configured as described in Step 5 (→ ä 26).

As an option, the device has two relays with limit values, which are either switched off, or
can be assigned to the input signal or the linearized value of analog input 1 or 2 or the
calculated values. The limit value is entered as a numerical value including the position of
the decimal point. Limit values are always assigned to a relay. Each relay can be assigned to
a channel or a calculated value. In the "Error" mode, the relay functions as a fault indicator
relay and switches for every fault or alarm.
The following settings can be made for each of the two limit values: assignment, function,
set point, hysteresis, operating mode

(e.g. upper limit value = 100m, hysteresis = 1m: limit value on = 100m, limit value off = 99m)

• Please note special situations if both the hysteresis and the delay time should be
activated simultaneously (see the following description in the Operating modes
section).

• Following a power failure, the limit value monitoring system behaves as if the limit
value had not been active before the power failure, i.e. the hysteresis and any delay
are reset.

Gradient

The "Gradient" operating mode is used to monitor the change in the input signal over time.
The alarm is triggered if the measured value reaches or overshoots the set value. If the user
configures a positive value, the limit value is monitored for rising gradients.
In the event of negative values, the falling gradient is monitored.
The alarm ends if the gradient drops below the set value again. A hysteresis is not possible
for the Gradient operating mode. The alarm can be damped by means of the delay time
function (second (s) unit) to reduce the sensitivity.

Special situation: hysteresis and delay at one limit value

In special cases when the hysteresis and limit value display are activated, a limit value is
switched based on the following principle.
If the hysteresis and limit value delay are activated, the delay is activated when a limit value
is overshot and measures the time since the value overshoot began. If the measured value
drops back below the limit value, the delay is reset again. This also happens if the measured
value falls under the limit value but is still above the specified value of the hysteresis. The
next time the limit value is exceeded, the delay time becomes active and starts measuring
from 0.

operating code, saving the current setup)

Access protection

The access protection locks all the editable parameters, i.e. setup can only be accessed once
the 4-digit user code has been entered.
Access protection is not activated at the factory. However, the configuration of the device can
be protected by a four-digit code.

Activating access protection:

1. Call up the menu ‘Setup’ → ‘System’ → ‘Access code’

2. To enter the code with the ‘+’ and ‘-’ keys, select the desired character and confirm with

‘E’. The cursor goes to the next position. Once the fourth position has been confirmed,
the entry is accepted and the user exits the ‘Access code’ submenu.

Once access protection has been successfully activated, the lock symbol is shown on the
display.

Saving the current setup/user setup

The current configuration of the device can be saved and is thus available as a specific setup
for a device reset or for a device restart. If you ordered the device with customized settings
which you specified, the preconfigured setup is also saved in the user setup.
Saving the setup:
Call up the menu ‘Expert’ → ‘System’ → ‘Save User Setup’. Confirm by configuring ‘Yes’. See
also → ä 37, Device reset.

6.4.7 Step 7: Configuring the display functions

The display is split into a 7-segment display section and a color section. The dot matrix

To configure the display: press ‘E’ and select ‘Display’.
Select → channel / calculated value and configure one of the following parameters.

→ Contrast: select contrast (can be configured in stages 1 to 7)
→ Brightness: select brightness (can be configured in stages 1 to 7)

If access protection is enabled, the device locks automatically after 600 seconds if it
has not been operated in this time. The display switches back to the operating
display.
To delete the code completely, use the ‘+’ and ‘-’ keys to select the "c" character and
confirm with ‘E’.

In accordance with Annex 2, Section 2(3) and Section 4 of TRbF 510 (Regulation/
construction and inspection guidelines for overfill protection units), and in accordance with
the approval guidelines for overfill protection units (ZG-ÜS), the device can be used as a limit
signal transmitter for overfill protection units with continuous level measurement for
storing combustible and noncombustible liquids which are hazardous to water.

Reason:

The device meets the requirement that plant units without an inspection label have to
comply with the general and special construction and inspection principles for overfill
protection in accordance with Annex 2, Section 4, in the following situations:
a. in the event of power supply failure and

b. if limit values are overshot or undershot and

c. if the connection wires between the upstream isolating transmitter and the meter are

disconnected, the safety-oriented message "Maximum level" appears (the limit relay
deenergizes).

The set limit values for overfill protection must be protected against unintentional
modification.

If several channels are active, the device switches automatically between the
channels configured.
Non-activated channels, calculated values and minimum and maximum values are
called up manually by pressing the ‘+’ and ‘-’ keys and appear for 5 seconds on the
display.

value is assigned experiences an error, the limit relay assumes the configured status. The
effect of the limit relay in the event of an error must be specified in the setup (energizes
or de-energizes). If a failsafe mode with a fixed error substitute value is configured in the
input assigned, the corresponding relay does not react to the error at the input. Instead
it checks the substitute value for limit value violation and switches depending on the limit
value violation. The default value specifies that the relay is energized.

6.5 In operation

6.5.1 ‘+’ and ‘-’ quick pick keys

You can use the ‘+’ and ‘-’ quick pick keys to switch through all the active channels (universal
inputs and calculated values) in the display mode. The measured value or the calculated
value is then displayed for 5 seconds. The channel name pertaining to the value displayed
appears in the color section of the display. The maximum and minimum value are offered for
each active channel.

You can exit a menu at any time by pressing the ‘+’ and ‘-’ keys simultaneously. Any changes
made are rejected.

6.5.2 Min./max. memory

The device writes the highest and lowest values of the inputs and calculated values and saves
them cyclically every 15 minutes in the nonvolatile memory.
Display:
Select the corresponding channel using the ‘+’ and ‘-’ quick pick keys.
Reset the min. and max. values:
Reset in the setup: select the channel (Analog in 1/2, Calc value 1/2 ), ‘Reset min/max’,
min./max. values of the corresponding channel are reset.

6.5.3 Device self-diagnosis, failsafe mode and cable open circuit
detection/measuring range limits

The device monitors its inputs for a cable open circuit, as well as its own internal functions
by means of comprehensive monitoring mechanisms in the device software (e.g. cyclic
memory test).

If the self-diagnosis of the device detects an error, the device reacts as follows:

• Open collector output switches

• Red LED lights up

• Relay switches (if active and assigned as a fault/alarm relay)

• Display goes to the error mode → color of channel affected changes to red and an error is

displayed

• The unit switches automatically between the active channels and the error display

Troubleshooting instructions and a list of all the error messages can be found in Section 9
‘Troubleshooting’.

A reset outside the setup (resetting without a user code) is only possible if this was
enabled for the channel in the setup (Allow reset, → Kap. 6.4.2). Press ‘E’ and select
‘Display’. All the channels for which resetting outside the setup is permitted are
displayed in succession. Select the corresponding channel and set to ‘Yes’. The
channel is reset.

At both universal inputs pressure sensors are connected.
With the following calculation steps the volume in the CV channels is finally calculated:

st

Calculation Step: Calculation of the filling level

Both pressure sensors provide the actual pressure at the installation point.From both
pressures (possibly adjusted for an offset; this has to be set in AI1 respectively AI2) a
pressure difference (Δp) is determined. If the pressure difference is divided through the
density of the medium multiplied with the gravitational acceleration the measured height is
gained.
Level h= Δp/(ρ*g)

The following units form the basis of the calculation:
Density ρ: [kg/m]
Pressure p: [Pa] or [N/m

]

The gravitational acceleration is defined by a constant:
Gravitational acceleration g=9.81m/s

NOTICE

Wrong calculation results through use of incorrect engineering units

‣ If the calculation is to be carried through correctly the measured signal (e.g. in mbar) has

to be converted into the according unit Pascal (Pa). This is achieved by a conversion
factor. Conversion factors can be found in the table → ä 51.

Examples for the conversion:
Water: density ρ=1000kg/m

Pressure measurement: pressure1 (bottom): Scale 0 to 800mbar (0 to 80000 Pa);
Present value: 500mbar (50000 Pa)
Pressure measurement: pressure2 (top): Scale 0 to 800 mbar (0 to 80000 Pa);
Present value: 150mbar (15000 Pa)

When using Pascal:

When using mbar:

h = b * Δp
Calculation of the correction factor b:
b = 1/(ρ*g)
for water: b = 1/(1000*9.81) = 0,00010194

2nd Calculation step: Calculation of the volume out of the height

By means of the linearization of the calculated height value the volume can be calculated.
This is done by assigning a certain volume value to every height value in dependency of the
tank shape.
This linearization is mapped over up to 32 supporting points. However, at a straight-linear
dependency of filling height and volume are sufficient.
The integrated tank-linearization module in FieldCare provides support here.
