7ML19985QL81 SITRANS LR 200 – QUICK START MANUAL Page EN-5mmmmmEnglishRUN Mode and PROGRAM ModeSITRANS LR 200 has 2 modes of operation: RUN and PROGRAM.After you complete the installation procedures and power up SITRANS LR 200, it starts in RUN mode and detects the distance to the material level in meters. This is the default start-up display mode.RUN Mode DisplayUse the hand programmer to control the display.Whenever a loss of echo occurs, LOE flashes and the Reliable Echo indicator is replaced by the Unreliable indicator. Before the Failsafe Timer expires, the letters LOE (Loss of Echo) alternate with the reading every two seconds. Once the Failsafe condition is established, LOE is displayed permanently. When a valid reading is received, the level reading display returns to normal operation.1 – Primary Reading (displays level, distance, or volume, in either units or percent). 2 – Parameter for Auxiliary Reading (can be set to display milliAmp value (HART only), distance, or confidence. It displays units, if applicable.)4 – Echo status indicator: Reliable Echo or Unreliable Echo 5 – Units or Percent6 – Active bar graph represents material level7 – Auxiliary Readingground lugshield.Using a screwdriver for leverage if necessary, unscrew the cover.

Page EN-10 SITRANS LR 200 – QUICK START MANUAL 7ML19985QL81mmmmmEnglishUsing P837 and P838 (perform this function at low tank levels)If SITRANS LR 200 displays an incorrect full level, or if the reading fluctuates between a false high level and a correct level, use P838 and P837 together to elevate the TVT (Time Varying Threshold) in this region and de-sensitize the receiver from any ‘base noise’ caused by internal antenna reflections, nozzle echoes, or other vessel false echoes.a. First rotate the instrument for best signal (lowest false echo amplitude)b. Determine the distance from the reference point to the material level.c. Select P838 and key in [distance to liquid level – 0.5m].d. Select P837, then press 2 (Learn) and ENTER . P837 will automatically revert to 1 (use Learned TVT) after a few seconds.9. Return to RUNPress PROGRAM to return to RUN mode: setup is complete.SITRANS LR 200 Communications: HART• You will need the full manual to acquire the list of applicable parameters.• The HART Device Descriptor (DD) may be obtained from the HART Communication Foundation at www.hartcomm.org• We recommend that you use Simatic Process Device Manager (PDM) to program your instrument.MaintenanceSITRANS LR 200 requires no maintenance or cleaning under normal operating conditions. If cleaning becomes necessary under severe operating conditions:1. Note the antenna material and the process medium, and select a cleaning solution that will not react adversely with either.2. Remove the instrument from service and wipe the antenna clean using a cloth and suitable cleaning solution.Notes: • Use this function only if there is a minimum distance of 2 meters from SITRANS LR 200 to the material. • Set P837 and P838 during start up, if possible.• If the vessel contains an agitator, the agitator should be running.Note: See mA Output with Level, Space, and Distance operation on page 8 for an illustration of the mA output with different modes of operation.LR-200QS-EN.fm Page 10 Wednesday, March 12, 2003 3:51 PMcross-referenced
