Air Purging System (Optional) For more frequent cleaning, a purging system can be installed between the flange and the horn antenna. The system provides an 1/8” inlet (female thread) on the flange where cooling air or cleaning fluid passes through the flange and exits the inside of the horn to clean it. The customer will supply the purging medium by a manual or automatic valve system. This option is only available with the universal flange for purging shown on page 17.

Dust Cap (Optional) Note: The dust cap must be removed before using the Air Purge feature. (See Air Purging System (Optional) on page 17). The dust cap fits onto the end of the horn and prevents the buildup of dust and other process material inside the horn. • It is particularly useful for applications in areas of high humidity, or with bulk solids with a high moisture content. Three sizes are available, to fit the standard 2", 3", and 4" horns. • Installation 1. Thoroughly clean inside the horn.

The alarm’s status remains true until the value drops below the limit minus the alarm hysteresis. The directions are reversed for low limit detection. Range: -999.99 to 999.99 m Values Default: 0.
2.4.2. Fail-safe Mode FB1 (FS MODE FB1) Fail-safe Mode occurs if the status of the input value is bad, or if the device has been put into Fail-safe mode using Simulation. One of three options can be selected for the material level to be reported when the LOE timer expires. Material level to be reported Substitute value (Default value used as output value). Options * Last value (Store last valid output value). Use bad value (Calculated output value is incorrect). 2.4.3.
3. Diagnostics Use these parameters to set up schedules for calibration and maintenance. The device will track itself based on operating hours instead of a calendar-based schedule, and will monitor its predicted lifetime. The maintenance warnings and alarms are communicated via either the Status or Condensed Status bytes. This information can be integrated into any Asset Management system. We recommend that you use SIMATIC PCS7 Asset Management Software in conjunction with SIMATIC PDM. 3.1.

Appendix D: Technical Reference Principles of Operation SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of solids and liquids1). Radar level measurement uses the time of flight principle to determine distance to a material surface. The device transmits a signal and waits for the return echo. The transit time is directly proportional to the distance from the material. Pulse radar uses polarized electromagnetic waves.
Higher order mathematical techniques and algorithms are used to provide intelligent processing of microwave reflection profiles. This “knowledge based” technique produces superior performance and reliability. Time Varying Threshold (TVT) Curves A Time Varying Threshold (TVT) curve hovers above the echo profile to screen out unwanted reflections (false echoes). sensor reference point High Cal. Pt. =0 obstruction at 1.2 m TVT curve material level at 2.9 m false echo true echo Low Cal. Pt.
a low dK value, which may cause the vessel bottom to be reported as the level instead of the actual material level, in low level conditions. CLEF range is the level below which the CLEF algorithm will be used: above this level the Center algorithm is used. Center of Mass selects the center of the echo for evaluation. Rising Edge selects the rising edge of the echo. Hybrid uses a combination of Center and CLEF, depending on the setting for CLEF range.
Far Range In applications where the base of the vessel is conical or parabolic, a reliable echo may be available below the vessel empty distance, due to an indirect reflection path. Increasing the range extension to 30% or 40% can provide stable empty vessel readings. Measurement Response The measurement response (Response Rate (1.2.)) limits the maximum rate at which the display and output respond to changes in the measurement.
If the LOE condition persists beyond the time limit set in 2.4.1. LOE Timer the LCD displays the Maintenance Alarm icon, and the text region displays the fault code S: 0 and the text LOE. If two faults are present at the same time, the fault code, error text, and error icon for each fault are displayed alternately. For example, Loss of Echo and Temperature Sensor Failure. S: 0 LOE S: 11 Temp.
