software. The second channel can be subsequently activated any time via Setup →
Analog in 2 →  26.

• Two-channel (2-channel): universal input 1 (Analog in 1) and universal input 2 (Analog

in 2) are pre-configured with the following values:
– Signal type: Current
– Signal range: 4-20mA

A full description of the "Differential pressure" application package is provided in the
following section.

To set up the device in single-channel/two-channel applications, please proceed with the
device setup as explained in Step 2 →  26.

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

difference between the two inputs is automatically calculated and the signal linearized
using the configured parameters of the analog inputs and the linearization points. As a
result, the volume is already shown on the display (= calculated value 2).

Prerequisites for correct value calculation and a functioning setup:

• Sensor 1 returns the higher pressure: connected to analog input 1 (Analog in 1)

• Sensor returns the lower pressure: connected to analog input 2 (Analog in 2)

Setup → Application → Diff pressure
Once the differential pressure application has been selected by confirming the Diff

pressure parameter, the editable parameters are displayed in succession and must be

configured individually for your application.
Some parameters are already configured for you if the application setup is selected

→  26.
The CV Factor parameter is used to take the density of the medium into account during

level measurement, i.e. it corresponds to the mathematic formula 1/(density*gravitational
acceleration). The default value for the factor is 1.

The density must be given in kg/m³ and the pressure in Pascal (Pa) or N/m². The
gravitational acceleration is defined by the constant on the earth’s surface.

This is g=9.81 m/s2. Tables and examples for converting application-related units into the
defined values kg/m³ and Pa or N/m² can be found in the appendix →  56.

Other parameters can be enabled in the setup for the corresponding parameter (see

7.4.2 Step 2: Configuring the universal input(s) (Analog in 1/2)

The device has one universal input, and optionally an additional universal input for
current, voltage, resistance thermometers (RTD) or thermocouples (TC).

The input is monitored for a cable open circuit (see the Measuring range limits table
→  37 and the Troubleshooting section →  40).

Minimum/maximum values at the inputs:

The current min./max. value is saved every 15 minutes. If the power supply is
disconnected (power off/power on), there may be a gap in the recording sequence.
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 must
be configured as described in Step 5 →  28.

Each universal input saves the smallest and largest measured value that is measured.
These values can be reset individually for every channel. In the setup, the administrator
can specify that 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. The min./max.
value is reset if a reset is performed and if channel scaling is changed.

To be configured like universal input, see Step 2 →  26

7.4.5 Step 5: Configuring the relays, assigning and monitoring limit values

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 an alarm relay
and switches each time a fault or alarm occurs.

The following settings can be made for each of the two limit values: assignment, function,
set point, hysteresis, switching behavior

The "Gradient" operating mode is used to monitor the change of the input signal over time.
The alarm is triggered if the measured value reaches or exceeds the preset value. If the
user configures a positive value, the limit value is monitored for increasing gradients.

In the case of negative values the decreasing gradient is monitored.
The alarm is canceled when the gradient drops below the preset value. A hysteresis is not

possible in the Gradient operating mode. The alarm can be suppressed for the set time

Special case: Hysteresis and delay for one limit value

In the special case that hysteresis and limit value delay are activated, one limit value is
switched according to the following principle.

If hysteresis and limit value delay are activated, the delay becomes active when a limit
value is exceeded and measures the time from which the value is exceeded. If the
measured value falls below the limit value, the delay is reset. This also occurs if the
measured value falls below the limit value, but continues to be higher than the set
hysteresis value. When the limit value is exceeded again, the time delay once more
becomes active and starts measuring from 0.

7.4.6 Step 6: Advanced device configuration (access protection/ operating code, saving the current setup)

Access protection

Access protection locks all the editable parameters, i.e. the 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 the menu ‘Setup’ → ‘System’ → ‘Access code’

2. To enter the code with the ‘+’ and ‘-’ keys, select the desired character and press ‘E’
to confirm. The cursor goes to the next position.

 After confirming the fourth position, the entry is accepted and the user exits the

‘Access code’ submenu.

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

If access protection is enabled, the device locks automatically after 600 seconds if the
device has not been operated during 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 press ‘E’ to confirm.

Saving the current setup/user setup

The current device configuration can be saved and is therefore available as a specific setup
for a device reset or for a device restart. If you ordered the device with customized settings,
the preconfigured setup is also saved in the user setup.

Saving the setup

7.4.8 Overfill protection

The German Water Resources Act (WHG) requires the use of overfill protection units on
vessels for water-polluting liquids. These units monitor the level and trigger an alarm in
time before the permitted fill level is reached. According to the approval guidelines for
overfill protection units (ZG-ÜS), suitable plant units must be used for this.

In accordance with these guidelines, the device can be used as a limit signal transmitter for
overfill protection units with continuous level measurement for storing liquids which are
hazardous to water (water-polluting liquids).

As a prerequisite the device must comply with the general and special construction
principles (chapters 3 and 4) of the approval guidelines for overfill protection units. This
means that the safety-oriented message "Maximum level" is displayed (the limit relay de­energizes) in the following situations:

• in the event of power supply failure and

• if limit values are exceeded or undershot and

• if the connection cables between the upstream transmitter and the limit signal
transmitter are disconnected.

Endress+Hauser 33

Commissioning RIA46

In addition, the configured limit values for overfill protection must be secured against
unintentional modification.

The following function must be activated if additional access protection should be
provided for the configuration software:

Select Setup / Expert → System → Overfill protect: German WHG

Configuration when operating the device in accordance with the approval guidelines
for overfill protection units:

The device must be set up and operated in accordance with these Operating Instructions

digit; once the digit has been confirmed, the cursor moves to the next position, or skips
back to the ‘System’ menu item once the fourth digit has been entered
The lock symbol appears on the display.

• Select Setup → System → Overfill protect: German WHG.
It is absolutely essential to assign the device to a WHG application. Confirming the
‘Overfill protect: German WHG’ parameter provides additional safety. The device status
must be changed if the device is being configured using the FieldCare operating
software, i.e. WHG must be disabled to be able to change parameters.

The effect of the limit relay in the event of an error (energizes or de-energizes) must be
specified in the setup. If a failure mode with a fixed error substitute value is configured
in the assigned input, 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 for the relay is "energized".

Application → Calc value 1/2

Failure mode

• Invalid:
The calculated value is not valid and is not output.

• Fixed value:
It is possible to enter a constant value that is output in the event of an error.

Diagnostics

Verify HW set

Following a hardware upgrade (e.g. additional relays, universal inputs etc.), it is necessary
to perform hardware verification, i.e. the hardware is checked by the firmware in the
device.

The "Verify HW set" function must be enabled in this case.

Simulation

The output value of the analog outputs and the switching state of the relays can be
specified in the simulation mode. Simulation remains active until it is set to "off". The start
and end of the simulation are saved in the diagnostic events.

Expert → Diagnostics → Simulation:

• Select the output to be simulated with the simulation value

• Select the relay to be simulated with the status

7.5.1 + 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 provided for each active channel.

Press the ‘+’ and ‘-’ simultaneously to exit a menu at any time. Any changes made are not
saved.

7.5.2 Min/Max memory

The device records 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.

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 →  26). 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.

7.5.3 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 comprehensive monitoring mechanisms in the device software (e.g. cyclic memory test).

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

• Open collector output switches

• Red LED is lit

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

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

displayed

• Display switches automatically between the active channels and the error

Troubleshooting instructions and a list of all the error messages can be found in the
‘Troubleshooting’ section →  40.

The following tables show all the parameters available in the configuration menu. The
values configured at the factory are marked in bold.

13.1 Further explanations on the differential pressure application at level measurement

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

13.1.1

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/m³]

• Pressure p: [Pa] or [N/m²]

The gravitational acceleration is defined by a constant:
Gravitational acceleration g=9.81m/s²

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 →  57.

Examples for the conversion:

Water: density ρ=1 000 kg/m
Pressure measurement: pressure1 (bottom): Scale 0 to 800 mbar (0 to 80000 Pa);
Present value: 500 mbar (50000 Pa)
Pressure measurement: pressure2 (top): Scale 0 to 800 mbar (0 to 80000 Pa);
Present value: 150 mbar (15000Pa)
When using Pascal:

h =

When using mbar:

h =

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.
