8 Maintenance and fault rectification 8 Maintenance and fault rectification 8.1 Maintenance When used in the correct way, no special maintenance is required in normal operation. 8.2 Remove interferences Reaction when malfunctions occur The operator of the system is responsible for taken suitable measures to remove interferences. Causes of malfunction A maximum of reliability is ensured. Nevertheless, faults can occur during operation. These may be caused by the following, e.g.
8 Maintenance and fault rectification ? Measured value on the indicating and adjustment module does not correspond to the value in the PLC l The menu item "Display - Display value" is not set to "PA-Out" à Check values and correct, if necessary ? No connection between PLC and PA network l Incorrect adjustment of the bus parameter and the segment coupler-dependent baud rate à Check data and correct, if necessary ? Instrument does not appear during connection setup l Profibus DP cable pole-reversed à C
8 Maintenance and fault rectification Reaction after fault rectification Depending on the failure reason and measures taken, the steps described in chapter "Set up" must be carried out again, if necessary. 8.3 Exchanging the electronics module If the electronics module is defective, it can be replaced by the user. In Ex applications only one instrument and one electronics module with respective Ex approval may be used.
8 Maintenance and fault rectification Load sensor software to PC At "www.vega.com/downloads" go to "Software". Select under "plics instruments and sensors" the suitable instrument series. Load the zip file via the right mouse key with "Save target as" e.g. on the desktop of your PC. Extract all files available in the zip file, e.g. to the desktop.
