1 Notes 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 (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 (page 75) which lists all the function names alphabetically and numerically.

1.4 General structure of the operating menu

The operating menu is made up of two levels:

• Function groups (00, 01, … , 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:

• Select the "basic setup" (00) function group.• Select the "tank properties" (002) (where the existing tank properties is selected).

1.4.1 Identifying the functions

For simple orientation within the function menus, 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:

Here after the position is always given in brackets (e. g. "tank properties" (002)) after the described function.

3.1 Function "measured value" (000)

This function displays the current measured value in the selected unit(see "customer unit" (042)) function). The number of digits after decimal point can be selected in the "no.of decimals" (095) function.

3.2 Function "tank properties" (002)

This function is used to select the tank properties.

Selection:• standard• aluminium tank• plastic tank• bypass/pipe• coax probe• concrete wall

standardThe "standard" option is recommended for normal containers for rod and rope probes.

aluminium tankThe "aluminium tank" option is designed especially for high aluminium silos that cause an increased level of noise when empty. This option is only useful for probes longer than 4 m. For short probes (< 4 m) select the "standard" option!

!Note! If "aluminium tank" is selected, the device calibrates of its own accord when first filled, depending on the medium's properties. Slope errors can, therefore, occur when beginning the first filling procedure.

plastic tankSelect the "plastic tank" option when installing probes in wood or plastic containers without metallic surfaces at the process connection (see installation in plastic containers). When using a metallic surface at the process connection, the "standard" option is sufficient!

!Note! In principle the employment of a metallic surface area should be preferred at the process connection!

bypass/pipe

The "bypass/pipe" option is designed especially for the installation of probes in a bypass or a stilling well. If this option is selected, the upper blocking distance is preset to 100 mm.

coax probeSelect the "coax probe" option when using a coax probe. When this setting is made, the evaluation is adapted to the high sensitivity of the coax probe. This option should, therefore, not be selected when using rope or rod probes.

concrete wallThe "concrete wall" option takes into account the signal-damping property of concrete walls when mounting with < 1 m distance to the wall.

3.3 Function "medium property" (003)

This function is used to select the dielectric constant.

7.7 Function "echo quality" (056)

The echo quality is the benchmark for measurement reliability. It describes the amount of reflected energy and depends primarily on the following conditions:

• Dielectric constant of the medium• probe type• Distance between sensor and productLow values increase the probability that the echo is lost through a change in measurement conditions, e. g. angels of repose or large measuring distance.

7.8 Function "offset" (057)

This function corrects the measured level by a constant value. The entered value is added to the measured level.

7.9 Function "output damping" (058)

Influences the time an output requires to react to a sudden level jump (63 % of steady state). A high value attenuates, for example, the influences of rapid changes on the measured variable.

User input:0 s ... 255 s

The default value depends on the selected application parameter "process cond." (004).

7.10 Function "upper block. dist" (059)

For rod and rope probes with lengths of up to 8 m, the upper blocking distance is preset to 0.2 m on delivery. For rope probes with lengths of more than 8 m, the upper blocking distance is preset to 2.5 % of the probe lengths.

For media DC > 7, the upper blocking distance for rod and rope probes can be reduced to 0.1 m, if the probe is mounted flush with the wall or in a nozzle of maximum 50 mm.

Blocking distance and measuring rangeAt the lower end of the probe there is no blocking distance but a transition region with reduced accuracy, see section "Maximum measured error".

1. Larger measurement range available on request.

2. The indicated blocking distances are preset. At media with DC > 7, the upper blocking distance UB can be reduced to 0.1 mm for rod and rope probes. The upper blocking distance UB can be entered manually.

!Note! Within the upper and lower blocking distance, a reliable measurement can not be guaranteed.

For stilling well applicationsThe upper blocking distance (UB) is preset to 100 mm when the "bypass/pipe" parameter has been selected in the "tank properties" (002) function.

Maximum measured errorTypical statements for reference conditions:DIN EN 61298-2, percentage of the span.

If the reference conditions are not met, the offset/zero arising from the mounting situation may be up to ± 12 mm. This additional offset/zero can be compensated for by entering a correction (function "offset" (057)) during commissioning.

15.3 Application errors

Error Output Possible cause Remedy

A warning or alarm has occurred.

Depending on the configuration see table oferror messages (see page 72)

1. see table of error messages (see page 72)

Measured value (00) is incorrect

"measured distance" (008) OK?

yes → 1. check "empty calibr." (005) and"full calibr." (006)

2. check linearisation:→ "level/ullage" (040)→ "max. scale" (046)→ "diameter vessel" (047)→ check table

no ↓An interference echo may have been evaluated.

yes → 1. carry out tank mapping→ basic setup

No change off measured value on filling/emptying

interference echo from installations, nozzle or extension on the probe

1. carry out tank mapping→ basic setup

2. if necessary, clean probe

3. if necessary, select better mounting position

E 641 (loss of echo) after turn on the power supply

If the instrument is configured to HOLD by loss of echo the output is set to any value/current.

noise level during the initialisation phase to high.

repeat once more "empty calibr." (005).Caution! Before conformation change with O or S to the edit mode.

Device displays a level when the tank is empty.

incorrect probe length

1. carry out automatic probe length detection when the tank is empty.

2. carry out mapping over entire probe when the tank is empty (probe free!).

Measured value incorrect (slope error in the entire measuring range)

tank properties incorrect.

medium properties incorrect.

LN < 4 m and "aluminium tank" tank properties selected→ calibration not possible→ selection→ select standard→ thresholds too high

Select lower medium properties.
