1Notes on use

You have various options for accessing the descriptions of instrument functions or how to enter

parameters.

1.1 Using the table of contents to locate a function

description

All the functions are listed in the table of contents sorted by function group (e.g. basic setup,

safety settings, etc.). You can access a more detailed description of a function by using a page

reference / link.

The table of contents is on page 3.

1.2 Using the graphic of the function menu to locate a

function description

This guides you step by step from the highest level, the function groups, to the exact function

description you require.

All the available function groups and instrument functions are listed in the table (see page 11).

Select your required function group or function. You can access an exact description of the function

group or function by using a page reference / link.

1.3 Using the index of the function menu to locate a

function description

To simply navigation within the function menu, each function has a position which is shown in the

display. You can access each function via a page reference/link in the function menu index (see

page 89) which lists all the function names alphabetically and numerically.

!Note!

The default values of the parameters are typed in boldface.

1.4 General structure of the operating menu

The operating menu is made up of two levels:

•Function groups (00, 01, 03, …, 0C, 0D):

The individual operating Selection of the instrument are split up roughly into different function

groups. The function groups that are available include, e.g.: "basic setup", "safety settings",

"output", "display", etc.

•Functions (001, 002, 003, …, 0D8, 0D9):

Each function group consists of one or more functions. The functions perform the actual operation

or parameterisation of the instrument. Numerical values can be entered here and parameters can

be selected and saved. The available functions of the “basic setup (00)” function group include,

e.g.: "tank shape (002)",

"medium property (003)", "process cond. (004)", "empty calibr. (005)", etc.

If, for example, the application of the instrument is to be changed, carry out the following

procedure:

1. Select the “basic setup (00)” function group.

2. Select the "tank shape (002)" function (where the existing tank shape is selected).

1.4.1 Identifying the functions

For simple orientation within the function menus (see Page 11 ff.), for each function a position is

shown on the display.

The first two digits identify the function group:

The third digit numbers the individual functions within the function group:

Hereafter the position is always given in brackets (e.g. "tank shape" (002)) after the described

function.

• safety settings 01

• linearisation 04

Symbols Meaning

ALARM_SYMBOL

This alarm symbol appears when the instrument is in an alarm state. If the symbol flashes, this indicates

a warning.

LOCK_SYMBOL

This lock symbol appears when the instrument is locked,i.e. if no input is possible.

COM_SYMBOL

This communication symbol appears when a data transmission via e.g. HART, PFOFIBUS-PA or

Foundation Fieldbus is in progress.

standard calm surface turb. surface

For all applications that do not fit into

any of the following groups.

Storage tanks with immersion tube or

bottom filling

Storage / buffer tanks with rough

surface due to free filling or mixer

nozzles

The filter and output damping are set

to average values.

The averaging filters and output

damping are set to high values.

-> steady meas. value

-> precise measurement

-> slower reaction time

Special filters to smooth the input

signals are emphasised.

-> smoothed meas. value

-> medium fast reaction time

add. agitator fast change test:no filter

Agitated surfaces (with possible

vortex) due to agitators

Fast change of level, particularly in

small tanks

All filters can be switched off for

service / diagnostic purposes.

Special filters to smooth the input

signals are set to high values.

->smoothed meas. value

->medium fast reaction time

->minimization of effects by

agitator blades

The averaging filters are set to low

values. The output damping is set to

0.

-> rapid reaction time

-> possibly unsteady meas. value

All filters off.

3.9 Function "empty calibr." (005)

This function is used to enter the distance from the flange (reference point of the measurement) to

the minimum level (=zero).

"Caution!

For dish bottoms or conical outlets, the zero point should be no lower than the point at which the

radar beam hits the bottom of the vessel.
