1.1.2 The operating menu

Structure of the menu

The parameters of the Prosonic S are organized in an operating menu (consisting of a main menu and several submenus). Parameters which are related to each other are comprised in a common parameter set. To simplify the navigation within the menu, a five-digit position code is displayed with each parameter set.

LVL 1 appl.para L1004

tank shape :dome ceiling medium property:liquid process cond:standard liq.



Identification of the parameter sets: 1Submenu 2 Number of the associated input or output 3 Number of the parameter set within the submenus

•The first digit (1) specifies the submenu

: – L: "level" – F: "flow" – A: "safety settings" – R: "relay/controls" – O: "output/calculations" – D: "device properties", "calibr. display" and "sensor management" – I: "system information" – S: "service" (only available if the service password has been entered)

Diagrams of the submenus can be found in the  Chap. 12, "Operating menu".

•The second digit (2) is used if the parameter set occurs several times within the Prosonic S (e.g. for different inputs or outputs).

Example: – O1201: "allocation current" for output 1 – O2201: "allocation current" for output 2

If the parameter set occurs only once wihtin the Prosonic S, "X" is indicated at this position.

•The last three digits (3) specify the individual parameter sets within the submenu.

1) Depending on the instrument version, the installation environment and the selected operating mode, some of the submenus may not be present.

Notes on use

Note! This chapter describes the commissioning of the Prosonic S via the display and operating module. Commissioning via FieldCare or the Field Xpert SFX100 is similar. For further instructions refer to the FieldCare Online Help or the Operating Instructions supplied with the Field Xpert SFX100.

After switching on the power supply for the first time, the instrument asks for a number of operating parameters:

1. Select the display language.

a. Press  or  to move the marking bar to the

desired language.

b. Press  to confirm your selection.

Note!

• For the sensors FDU9x the option "automatic" is recommended (default setting). With this setting the Prosonic S recognizes the type of sensor automatically.

• For the sensors FDU8x the type has to be assigned explicitly. The automatic sensor recognition does not work for these sensors.

Caution! After exchanging a sensor, observe the following: The automatic sensor recognition is also active after a sensor has been exchanged recognizes the type of the new sensor automatically and changes the "detected" parameter if required. The measurement continues without a break. Nevertheless, in order to ensure perfect measurement, the following checks are required:

•Check the "empty calibration" and "full calibration" parameters. Adjust these values if required. Take into account the blocking distance of the new sensor.

•Go to the "distance correction" parameter set and check the displayed distance. If required, perform a new interference echo suppression.

Note!

Number and type of the parameters in this set depend on the selected linearization type. Only the parameters "type" and "mode" are always present.

The "linearization" is used to convert the level into other quantities. Especially, it can calculate the volume or mass within a vessel of arbitrary shape. The Prosonic S provides different linearization modes for the most common types of vessels. Additionally, a linearization table for arbitrarily shaped vessels can be entered.

"type"

Use this parameter to select the type of linearisation.

Selection:

• none In this linearization type the measured level is not converted but displayed in the selected level unit (see above, "unit level").

• linear In this linearization type the displayed value is proportional to the measured level.

The following additional parameter have to be specified: – the unit for the linearized value, e.g. kg, m

, ft3, ... ("customer unit")

– the maximum capacity (a) of the vessel, measured in the customer unit ("maximum scale").

• horizontal cylinder

• sphere In these linearization types the measured level is convertet to the volume in a horizontal cylinder or a spherical tank.

2.1.7 Interference echo suppression: Basic principles

The "check value" and "distance mapping" parameters are used to configure the interference echo suppression of the Prosonic S. The following picture shows the operating principle of the interference echo suppression:

A The envelope curve (a) contains the level echo and an interference echo. Without interference echo suppression,

the interference echo is evaluated.

B The interference echo suppression generates the mapping curve (b). This curve suppresses all echos within the

range of mapping (c).

C From now on, only those echos are evaluated, which are higher than the mapping curve. The interference echo is

below the mapping curve and is therefore ignored.

Note! In order to include all interference echos, the interference echo suppression should be performed with the level as low as possible. If during commissioning the vessel can not be sufficiently emptied, it is advisable to repeat the interference echo suppression at a later point of time (as soon as the level reaches nearly 0%).

"check distance"

Use this parameter to state if the displayed distance D

matches the real distance D (measured

display

by a rule for example). Based on your selection, the Prosonic S automatically proposes a suitable range of mapping. You have got the following options:

• distance = ok Choose this option if the displayed value D

matches the real distance D.

display

After selecting this option, the Prosonic S changes to the "LVL N distance mapping" parameter set. The preset range of mapping is identical to D. That means: all interference echos above the current product surface will be suppressed by the mapping curve.

• distance too small Choose this option if the displayed value D

is smaller than the real distance D.

display

In this case the currently evaluated echo is an interference echo. After selecting this option, the Prosonic S changes to the "LVL N distance mapping" parameter set. The preset range of mapping is slightly larger than D

. Therefore, the currently evaluated

display

interference echo is suppressed by the mapping curve. If after the mapping D

is still too small, repeat the mapping until D

• distance too big Choose this option if the displayed value D This error is not caused by interference echos. Therefore, no interference echo suppression is

• distance unknown Choose this option if you do not know the real distance D. In this case, an interference echo suppression can not be performed and the Prosonic S returns to the "level 1(2)" submenu.

• manual Choose this option if you want to define the range of mapping manually. The Prosonic S changes to the "LVL N distance mapping" function, where you can define the required range of mapping.

"actual distance N" (N = 1 or 2)

Displays the currently measured distance between the reference point of the sensor and the product surface. Compare this value to the real distance in order to find out if currently an interference echo is evaluated.

"range of mapping"

Use this parameter to specify the range of the mapping curve. Normally, a suitable value has already been entered automatically. Nevertheless, you can change this value if required.

"start mapping"

Select "yes" in this parameter in order to start the mapping. When the mapping is finished, the state is automatically changed to "enable map". The "LVL N state" parameter set appears, in which the currently mesaured level and distance are displayed. Compare the displayed distance to the real distance in order to decide if a further mapping is necessary. If yes: Press the left-arrow key () in order to return to the "LVL N dist. map" parameter set. If no: Press the right-arrow key (), in order to return to the "level (LVL) N" submenu.
