Carefully selected components and compliance with prescribed quality standards guarantee the high reliability of the SITRANS LR 400. In the unlikely event of a fault, please consult the instructions in this chapter before contacting the responsible customer services. Classification of faults Faults occurring in the SITRANS LR 400 can be classified in the following groups: • faults caused by ambient influences: over and undertemperature, moisture, contamination by the measuring medium and other substances, mains faults, vibration • faults in the device: display, electronics, mechanics, connections Please try to determine the fault and localize it as accurately as possible.. Self-test mmmmm Troubleshooting If the fault cannot be eliminated with the measures described, follow the instructions in “Maintenance and repairs” on page 65. Note: The device performs a self-test every time it is switched on. It is ready for operation when the LCD displays the multi-display and the control elements can be operated. If you get fault messages after the self-test, please proceed according to “Fault messages” on page 64. If there is a malfunction in the device, you can also activate the self-test manually with Parameter 3.2.1. Page 62 Sitrans LR 400 – INSTRUCTION MANUAL 7ML19985FH01 chap7.fm Page 63 Tuesday, October 9, 2001 1:06 PM Symptoms, causes and their remedy Symptom Possible causes No display on the Defective or missing LCD power supply LCD is defective Electronics are defective A fault message is displayed Set the device parameters and functions manually. Internal fault Call the fault display in Function 3.1. Proceed as described in “Maintenance and repairs” on page 65. mmmmm 7ML19985FH01 The device is not parameterized correctly according to the application Troubleshooting An incorrect measured value appears after Auto-Setup. No measured value appears after the AutoSetup (measured value “0” and the fault display flashes) Internal fault Remedy Check that the power supply is connected correctly. Replace the device fuse if necessary (see “Changing the device fuse” on page 65). Connect a HART Communicator or a PC/Laptop with SIMATIC PDM software. If the device can be parameterized from there, the LCD is defective. Measure the analog current output. If the output current is not between 3.6 mA < x < 22 mA, the electronics are defective. Replace the electronics unit as described in “Maintenance and repairs” on page 65. Call the fault display in Function 3.1. Proceed as described in “Maintenance and repairs” on page 65. Sitrans LR 400 – INSTRUCTION MANUAL Page 63 chap7.fm Page 64 Tuesday, October 9, 2001 1:06 PM Fault messages The device indicates faults with a flashing letter on the right of the first line of the display. It has the following meaning: • W: Warning – device is still ready for operation but faults may occur • F: Fault – sporadic fault, device conditionally ready for operation • D: continuous fault – device is not ready for operation Under Parameter 3.1.x, you will find a fault log which indicates the type of the fault(s) which occur. It indicates the device function status in which the fault occurred and outputs an fault message in plain text. The possible fault messages are as follows: mmmmm Troubleshooting Function Message Possible causes Remedy Contact your Siemens MW cable Microwave cable not connected or line Milltronics defective break representative Contact your Siemens Sensor Overtemperature in device Milltronics defective representative Sensor Antenna contaminated, damaged or not Check antenna Check the antenna mounted Check the max.

Page 64 Make the following modifications, starting with a. Check whether the fault still occurs after every step: b. Check the set measuring range and the dead band (Function 4.2.2.3). c. Check whether the filling speed has been correctly set (Function 4.2.2.5). d. Reduce the reflectivity (Function 4.2.2.6). e. Switch off the automatic fixed target detection (Function 4.2.3.6) if necessary. f. Switch off the multiple echo detection (Function 4.2.3.2) if necessary. Sitrans LR 400 – INSTRUCTION MANUAL 7ML19985FH01 chap8.fm Page 65 Tuesday, October 9, 2001 1:29 PM Maintenance and repairs Changing the device fuse Warning: The device fuse must only be changed by qualified personnel who are familiar with the installation, commissioning, and operation of the SITRANS LR 400. The device fuse is located on the power supply unit board. Position of device fuse and electronics cover locking: device fuse electronics cover locking mmmmm Maintenance Change a defective fuse as follows: 1. 2. 3. 4. Disconnect the device from the power supply. If your device is in a pressure-tight housing, release the cover locking of the electronics cover with an Allen key (see above). Remove the electronics cover from the housing. If your device has an optional operating and monitoring module, pull it out of the front of the housing. Disconnect the plug of its cable from the socket and place the operating and monitoring module on one side. Caution! Take care not to bend or damage any of the cables. Touching the electronic circuit boards can damage sensitive parts. 7ML19985FH01 Sitrans LR 400 – INSTRUCTION MANUAL Page 65 chap8.fm Page 66 Tuesday, October 9, 2001 1:29 PM 5. Lift the device fuse carefully from its clip with a suitable tool (tweezers, flat-tipped pliers or similar) (see above), and remove it from the housing. Insert a new fuse. Only use original spare fuses! Press it into the clip until it snaps in audibly. Reassemble the device in reverse order. 6. 7. Caution! The device contains a second fuse that is not accessible via the front side. This fuse is only to be replaced by the manufacturer (following a complete safety check of the device). Disconnecting the electronics part from the mechanical part For maintenance it is possible to separate the electronic enclosure of the device from the mechanical part (flange) without endangering the pressure tightness of the vessel. Release the threaded ring of the electronics part from the mechanical part with a hook key 68/75 and remove the electronics part. Place the enclosed plastic cap on the mechanical part to prevent from soiling. Cleaning the antenna Depending on the type of measuring material, it may be necessary to clean the antenna at certain intervals to remove soiling which could affect the measuring result. You can clean it without removing the flange from the vessel. Proceed as follows: 1. Disconnect and remove the electronics part as described above. mmmmm Maintenance Caution! As soon as you remove the pressure window from the mechanical part the vessel is no longer pressure-tight and explosion protected! 2. Unscrew the pressure window which becomes accessible after removing the threaded ring with an M36 open-ended wrench and lift it off the mechanical part together with the white PTFE stopper. 3. Clean the inside of the antenna with compressed air and/or a brush. Make especially sure that the pressure window thread is clean. Apply fresh grease to the thread as required. Check the O-rings for damage and replace them if necessary. If the PTFE stopper has come loose when removing from the pressure window, reinsert it long end first in the mechanical part. Push it into the guide up to its thickened stop. Place the pressure window and screw it tight. Reattach the electronics part to the mechanical part. You can align the rotatable housing head before tightening the threaded ring. Check the pressure tightness of the vessel. 4. 5. 6. 7.
