8 Maintenance and fault rectification 8 Maintenance and fault rectification 8.1 Maintenance, cleaning When used in the correct way, no special maintenance is required in normal operation. In some applications, product buildup on the sensor diaphragm can influence the measuring result. Depending on the sensor and application, take precautions to ensure that heavy buildup, and especially a hardening thereof, is avoided. If necessary, the transmitter has to be cleaned.
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 Instrument repair You can download a return form (24 KB) in the Internet from our homepage www.wika.com under the item "Service".
