Please note the following: • The user is responsible for all changes and repairs made to the device. • All new components must be provided by Siemens. • Restrict repair to faulty components only. • Do not re-use faulty components.
The echo is processed by the SITRANS LU180 using Siemens' proven ‘Sonic Intelligence’ techniques. Filtering is applied to help discriminate between the true echo from the material, and false echoes from acoustical and electrical noises and agitator blades in motion.
Installing and mounting Environmental The SITRANS LU180 should be mounted in an area that is within the temperature range specified, and that is suitable to the housing rating and materials of construction. It is advisable to keep the device away from high voltage or current runs, contactors and SCR control drives.
Installing and mounting 3.3 Threaded Threaded ① Electronics ② Mounting thread ③ Sensor The SITRANS LU180 is available in three thread types: 1. 2" NPT ((Taper), ANSI/ASME B1.20.1) 2. R 2" ((BSPT), EN 10226) 3. G 2" ((BSPP), EN ISO 228-1 Note Before inserting the SITRANS LU180 into its mounting hole, ensure that the threads are of the same type to avoid damaging the device.
Installing and mounting 3.4 Flange adapter (optional) Flange adapter (optional) The SITRANS LU180 can be fitted with the optional 75 mm (3") flange adapter for mating to 3" ANSI, DIN 65PN10 and JIS 10K3B flanges. ① SITRANS LU180 ② Optional flange adapter (2" NPT - 7ML1830-1BT, 2" BSPT - 7ML1830-1BU) SITRANS LU180 Operating Instructions, 06/2016, A5E37100674-AA...

Commissioning 5.2 Calibration Calibration The calibration of the mA output may be done such that its span will be either proportional or inversely proportional to the material level. Note The 4 and 20 mA levels may be calibrated in any order. Proportional span Inversely proportional span high level = 20 mA...

During commissioning, viewing the graphic can assist the user in properly locating and installing the unit to achieve optimum performance. ①...
Operating Adjustments There are several operating adjustments that can be made to the SITRANS LU180. To access the operating adjustments, simultaneously press the "4" and "20" keys until the desired adjustment is obtained. A viewing sequence of the stored value is automatically initiated. During this time the value can be changed by pressing either the "4"...
Operating 6.2 Calibration, scrolling method Calibration, scrolling method The 4 and 20 mA calibration values can be selected where reference levels, either from the material in the vessel or from a target, cannot be provided. This method can also be used to trim the output levels obtained by the Calibration: reference method (Page 24) To change the stored calibration value, obtain the 'c 4' or 'c 20' display.
Operating 6.4 20 mA calibration 20 mA calibration 20 mA calibration initiated view stored 20 mA calibration value (i.e. 0.50 m) press ”4” to increase to new calibration value (i.e. 0.45 m) new calibration value Blanking Blanking is used to ignore the zone in front of the transducer where false echoes are at a level that interfere with the processing of the true echo.
Operating 6.6 Adjusting the blanking value Adjusting the blanking value To change the stored blanking value, go to the 'bL' display (as described in Adjustments (Page 27)), and proceed as follows: 1. Press the "20" key to increase the blanking value, or the "4" key to decrease it until the correct value is displayed.

Operating 6.9 Fail-safe Fail-safe In the event a loss of echo or fault condition exceeds the 'Waiting' period (see Speed of response (Page 30), or Fail-safe timer (Page 33)), the '?' icon appears and one of the following fail-safe defaults is immediately effected. default reading full...
Operating 6.11 Fail-safe timer 6.11 Fail-safe timer The fail-safe timer allows the user to vary the ‘waiting’ period from the time a loss of echo or operating fault condition begins, until the fail-safe default is effected. The ‘waiting’ period is adjustable from 1 to 15 minutes, in 1 minute increments.
Operating 6.14 Adjusting the units 6.14 Adjusting the units To change the units, go to the 'Un'' display (as described in Adjustments (Page 27)), and proceed as follows: 1. Press the "20" key to scroll forward through the available options (1-2), and press the "4" key to scroll backwards.
Troubleshooting The echo is not reliable and the LU180 is waiting for a valid echo before updating the measurement. Probable causes are: • Material or object in contact with sensor face • The LU180 is too close to the fill point •...
