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.

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.

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.

The "flow N check value" and "flow N mapping" parameter sets are used to configure the inter- ference echo suppression of the Prosonic S. The following picture shows the operating principle of the interference echo suppression:

L00-FMU90xxx-19-00-00-yy-030

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 contains all echos which are

located 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

ignored because it is lower than the mapping curve.

Note! In order to include all interference echos, the interference echo suppression should be performed with the level as low as possible. If during the commissioning the channel 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%).

Use this parameter to state if the displayed distance D 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 matches the real distance. After selecting this option, the "flow N mapping" parameter set appears. The preset range of mapping is equal to D. That means: all interference echos which are above the current product surface will be mapped out in the interference echo suppression.

• distance too small Choose this option if the displayed value is smaller than the real distance D. In this case, the currently evaluated echo is an interference echo. After selecting this option, the "flow N mapping" parameter set appears. The preset range of mapping is slightly larger than D be mapped out by the interference echo suppression.

• 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 performed and the Prosonic S returns to the "flow N" parameter set. Check the calibration parameters, especially the "empty calibration".

• distance unknown Choose this option if you do not know the real distance D. In this case, an interference echo supression can not be performed and the Prosonic S returns to the "flow N" parameter set.

• manual Choose this option if you want to define the range of mapping manually. The "flow N mapping" parameter set appears, where you can define the required range of mapping.

3.2.1 Basics

The flow measurement can be impaired by backwater on the downstream side or by dirt within the flume. The backwater and dirt detection function can detect these errors and ensure that the Prosonic S reacts appropriately. Two sensors are required for backwater and dirt detection. The first sensor is mounted above the upstream water, the second above the downstream water. The Prosonic S evaluates the ratio of the downstream level h

Backwater detection

Backwater is detected if the ratio h In this case, the flow is continuously reduced to 0. An alarm relay can be configured which indicates the backwater alarm.

The safety distance can be used to detect flooding if a FDU90 sensor with flooding protection tube is applied. In this case the safety distance must be chosen in a way that it ends slightly below the lower edge of the flooding protection tube: SD = min. 4 cm (1.6 in)

In order to indicate the flooding, a diagnostic relay can be parametrized with the allocation "safety distance channel 1/2" ( ä 78).

5.2 The "pump control N" submenu - standard

(N = 1 or 2)

Note! Depending on the order code of the instrument, different functionalities can be configured for the pump control. The order code of the instrument can be found on the nameplate and in the operating menu at "system information/device information".

This chapter is only valid for instruments with standard pump control (FMU90-*1********** and FMU90-*2**********).

For the enhanced pump control see chapter 5.3 (FMU90-*3********** and FMU90-*4**********).

Note! The "pump control N" submenus are only present if "pump control" has been selected in "device properties/operating parameters/controls".

5.2.1 Basic principles

Switch points

The pump control is used to start or stop pumps depending on the measured level. To do this, a switch-on point and a switch-off point is defined for each pump. Additionally, a relay is assigned to the pump and the switching is performed by this relay. Two cases can be distinguished for the swichting behaviour of this relay:

a. Switch-on point > Switch-off point

The pump is switched on if the level rises above the switch-on point (A). It is switched off if the level drops below the switch-off point (B). Example: Emptying of a flood control reservoir.

A: switch-on point; B: switch-off point; C: pump on; D: pump off

b. Switch-on point < Switch-off point

The pump is switched on if the level drops below the switch-on point (A). It is switched off if the level rises above the switch-off point (B).

Operating mode

The "relays/controls" menu

L00-FMU90xxx-19-00-00-yy-052

The Prosonic S can control several pumps simultaneously - depending on the number of relays (s. feature 70 of the product structure). If two or more pumps are applied for one level channel, you can choose between two different operating modes:

a. Non-alternating pump control

In this mode, each pump is switched according to the switching points allocated to it.

b. Alternating pump control

In this mode, the switching points are not allocated to the individual pumps. Instead, the relays are switched in a way that ensures uniform usage of all pumps. This is achieved by the following rules:

1. If the level rises above one of the switch-on points, that relay switches on, which at that moment has been switched off the longest time. This is not necessarily the relay to which the switch-on point belongs.

2. If the level drops below one of the switch-off points, that relay switches off, which at that moment has been switched on the longest time. This is not necessarily the relay to which the switch-off point belongs.

However, there are two restrictions to these rules:

3. Rising of the level above a switch-on point effects switching on of a relay only if the corresponding switch-off point has been reached before.

4. Dropping of the level below a switch-off points effects switching-off of a relay only if the corresponding switch-on point has been reached before.

Note!

If two pumps in the same range are to operate alternately, their switch-on and switch-off points are identical. This switching response can be achieved by assigning switch points to the second relay which can never be reached.

Example

In the switching range between 60% and 40%, two pumps should be operated alternately, i.e. when pump 1 in running, pump 2 is switched off and vice versa. These relays are programmed as follows: – Relay 1: switch-on point: 60%; switch-off point: 40% – Relay 2: switch-on point: e.g. 160%; switch-off point: e.g. 120%.

L00-FMU90xxx-19-00-00-yy-053

Limit control versus pump rate control

If several pumps are connected, you can choose between limit control (as described above) and pump rate control.

Limit control

If limit control has been selected, the relays are switched according to the swichting points as described above.

Pump rate control

If pump rate control has been selected, there is only one switch-on point and one switch-off point, which are valid for all relays. Additionally, a desired pump rate has to be specified. If the level rises above (or falls below) the switch-on point, initially only one pump is switched on. If the desired pump rate has not been achieved after the selected hook-up interval, an additional pump is switched on. Similarly, further pumps are switched on in intervals until the desired pump rate has been achieved.

However, if the level is already near to the switch-off point (distance < switch-on barrier), no further pumps are swtiched on, even if the pump rate has not yet been achieved.

5.3 The "pump control N" submenu - enhanced

(N = 1 or 2)

This chapter is only valid for instruments with enhanced pump control (FMU90-*3********** and FMU90-*4**********).

For the standard pump control see chapter 5.2 (FMU90-*1********** and FMU90-*2**********).

Note! The "pump control N" submenus are only present if "pump control" has been selected in "device properties/operating parameters/controls".

5.3.1 Basic principles

The pump control is used to start or stop pumps depending on the measured level. Up to two pump controls can be defined. One or more pumps can be allocated to each pump control. The pumps are switched on and off by the relays of the Prosonic S. The switching behavior depends on:

• the selected "function"

• the selected type of "load control" (only relevant for alternating pump control)

Page 93

The "relays/controls" menu

Functions "limit simple" and "limit parallel"

For these functions, a switch-on point and a switch-off point is defined for each pump. The switching behaviour depends on the relative position of these two switching points:

a. Switch-on point > Switch-off point ("Emptying")

The pump is switched on if the level rises above the switch-on point (A). It is switched off if the level drops below the switch-off point (B).

b. Switch-on point < Switch-off point ("Filling")

The pump is switched on if the level drops below the switch-on point (A). It is switched off if the level rises above the switch-off point (B).

L00-FMU90xxx-19-00-00-yy-052

1: "Emptying" (switch-on point > switch-off point); 2: "Filling" (switch-on point < switch-off point) A: switch-on point; B: switch-off point; C: pump on; D: pump off

Note! If several pumps are allocated to a pump control, the switching direction of all these pumps must be the same. Mixing of "filling" and "emptying" is not allowed.

The difference between "limit simple" and "limit parallel" relates to the control of more than one pump:

• limit simple (A) With this function, only one pump can be running at a time. Before a pump is switched on, the previously running pump is switched off automatically. Details depend on the relative position of the switching points, especially on the fact if the switching ranges of different pumps are overlapping. (Refer to the example in the diagram below).

• limit parallel (B) With this function, several pumps can be switched on at the same time.

Example ("Emptying" with three pumps)

Alternating pump control

Optionally, a number of pumps can be allocated to the alternating pump control. In this mode, the switching points are no longer allocated to the individual pumps. Instead, a desired degree of use must be defined for each pump (e.g. equal usage of all pumps). If the level rises above (or falls below) the switch-on point and a pump has to be switched on, the Prosonic S selects the pump according to an algorithm which ensures that in the course of time the desired degrees of use are obtained for all pumps. The same is valid for the switching-off of pumps.

Note! For the limit control (simple or parallel) it can be defined for each pump individually if it is to take part in the alternating pump control. For pump rate control, it is only possible to allocate all pumps or no pump to the alternating pump control.
