SITRANS LR 200

SITRANS LR 200 is to be used only in the manner outlined in this manual, otherwise protection

provided by the equipment may be impaired.

SITRANS LR 200 is a 2-wire loop-powered, continuous level-measuring instrument that utilizes

advanced pulse radar technology at 5.8 GHz (6.3 GHz in the USA). The instrument consists of an

electronic component coupled to the antenna and process connection.

Specifications

For a complete listing, see the SITRANS LR 200 Instruction Manual. For Approvals information,

please refer to the process device tag.

Ambient/Operating Temperature

Power

• Maximum 30 Vdc • 4 to 20 mA

WARNING: Changes or modifications not expressly approved by Siemens

Milltronics could void the user’s authority to operate the equipment.

Note: This equipment has been tested and found to comply with the limits for a Class A

digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference when the equipment is operated in a

commercial environment. This equipment generates, uses, and can radiate radio frequency

energy and, if not installed and used in accordance with the instruction manual, may cause

harmful interference to radio communications. Operation of this equipment in a residential

area is likely to cause harmful interference in which case the user will be required to correct

the interference at his own expense

Note: Process temperature and pressure capabilities are dependent upon information

on the process device tag. The reference drawing listed on the tag can be downloaded

from the Siemens Milltronics Web site at www.siemens-milltronics.com

RUN Mode and PROGRAM Mode

SITRANS 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 ModeDisplay

Use 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 Percent

6 – Active bar graph represents material level

7 – Auxiliary Reading

Using 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 RUN

Press PROGRAM to return to RUNmode: 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.

Maintenance

SITRANS 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 agitatorshould berunning.

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.
