Sitrans probe lu instruction manual

Eviter un serrage excessif! Viene restituita la distanza in metri al livello di riferimento del materiale, da Vuoto livello di processo vuoto. Valore Livello Default Portata max. Se SITRANS Probe LU visualizza un livello di pieno errato o se la lettura varia tra un alto livello falso e un livello corretto, utilizzare le funzioni P e P contemporaneamente onde evitare il rilevamento di false eco.

Wij raden u sterk aan de uitgebreide versie van de handleiding te verwerven zodat u uw instrument zo optimaal mogelijk kunt gebruiken. De volledige handleiding is beschikbaar op onze website: www. De ultrasone meetversterker bevat een temperatuurelement om de temperatuurveranderingen in de toepassing te compenseren.

Opmerking: De installatie mag uitsluitend worden uitgevoerd door gekwalificeerd personeel en in overeenstemming met lokale regelgeving. Safety Extra Low Voltage Wanneer de kabel door een doorvoer wordt gevoerd, gebruik dan uitsluitend wartels van de goede maat die zijn goedgekeurd voor een waterdichte toepassingen. De primaire uitlezing toont het materiaalniveau in meters ten opzichte van Leeg Empty proces leeg niveau.

Page 36 See note on next page for more details. Enter the distance between Empty process empty level and Span process full level , in units set in P Span can be set at any distance above Empty level. The default setting for P is 0 volume calculation not required. Page 40 In P you assign a corresponding volume value to each breakpoint. For more details on secondary index operation, see page Page 42 0. Page 43 If you are measuring head and flow, follow the Flow Breakpoints instructions on page Primary Index P Page 47 Enter the reading that is to correspond to a 4 mA output.

Use percent or units, depending on the setting for P P Vessel or Channel Shape To display flowrate instead of volume, see page Page 48 Prevents the mA output from rising above this maximum level for a measurement value.

This does not restrict the Failsafe or manual settings. Range 3. Calibrates the 4 mA output. Calibrates the 20 mA output. If both calibrations are done, then do Offset at a known high level, and Sound Velocity at a known low level.

Page 52 The acoustic beam atmosphere temperature is unknown. For best results, calibrate with the level at a known value close to empty. Page Temperature Compensation P To P Use this function when you want to manually override the temperature sensor with a fixed temperature value.

P is automatically updated whenever Measurement Response P is altered. Page 57 The window then returns to its normal width. However, measurement reliability is affected.

Any address other than 0 will cause the output current to be a fixed value, and the current will not indicate the reading. Values Range 0 to 16 Units are those set in P Echo Processing P to P The following parameters are for authorized Siemens Milltronics Service personnel or technicians familiar with Siemens Milltronics echo processing techniques.

Allows the material level to drop below Empty process empty level , without generating an LOE state. Values view only —20 to 99 Display Press the measurement key to get a new reading that will update echo strength.

Then the learned profile, or part of the learned profile, is used to screen out false echoes. The following parameters are for authorized Siemens Milltronics Service personnel or technicians familiar with Siemens Milltronics echo processing techniques.

Page 65 6. P will revert to 1 use Learned TVT automatically after a few seconds. Page Measurement P to the previous setting after the test! P Temperature Displays the temperature in C as monitored by the connected transducer.

This value is not affected by Temperature Source P Page 69 The learned TVT curve is not lost. Key in the height of the vessel bottom in level units. Page Detailed Setup Enter up to 32 level breakpoints, where the corresponding volume is known. The breakpoints can be ordered from top to bottom, or the reverse.

Breakpoints are normalized to 0. Page 93 Use the level breakpoints to enter head level values, and the volume breakpoints to enter flow volumes. Use the Flow table associated with your open channel device Parshall flume, v-notch weir, or other measuring device to calculate the flow rate for each breakpoint. Page 94 Example: v-notch weir: Breakpoints flow characterization Break- Head Flow point level volume 0. Threshold Short default 10 The Threshold parameters are for use by authorized Siemens Note: Service personnel or technicians familiar with Siemens echo processing techniques.

Sets the minimum Short Shot echo confidence that the echo must meet in order to be considered a valid echo. Page 96 Open menu Device — Offset and Velocity Calibration, select the option to change calibration, select the calibration type, then enter new calibration value. Echo Sampling The Echo Sampling parameters are for use by authorized Siemens Note: Service personnel or technicians familiar with Siemens echo processing techniques.

Page 97 , within which an echo should be considered valid. Range: 0 to 20 m Hand programmer values This parameter is for use only by Siemens service technicians. The transducer face. Page 99 2. Then the learned profile, or part of the learned profile, is used to screen out false echoes. Page Distance meters 2. For use only by Siemens personnel. This parameter cannot be reset to the factory default. Page Adjusts the Probe LU response to decreases in the actual material level.

Empty Rate is automatically updated whenever Response Rate is altered. Page Output Used to request an operating mode from the Function Block. Out-of-service mode is a safety feature, used for service purposes to stop the transducer firing. Page Identifies the active Control Recipe Unit Procedure or the related Unit for example, reactor, centrifuge, drier. Batch operation default 0 Identifies the active Control Recipe Operation.
