8.3 Replacing transmitter or PCB board
Since the MAG 8000 and MAG 8000 CT do not have a removable SENSORPROM (EEprom),
special care must be taken when replacing a damaged or defective transmitter or PCB board
to ensure proper operation and continued accuracy. There are three ways to achieve an easy
and successful replacement meter:
1. Order a complete transmitter as a spare part, which comes configured the same way as
the original meter left the factory. The system serial number of the original meter must be
provided when ordering the replacement.
2. Order a complete transmitter as a spare part with default settings and a blank product label.
Final configuration is done on-site. Missing data and configuration can be uploaded from
the old meter or it can be read from the old meter product label.
3. Order only a replacement PCB board. The PCB board can only be ordered for basic or
advanced version with default settings. When making the configuration on site, the service
mode must be selected in the Flow Tool/SIMATIC PDM and the hardware lock key must
be mounted on PCB board to change important parameters.
Note
If MAG 8000 CT transmitter or sensor has to be replaced, a reverification of the whole meter
must be made to obtain custody transfer approval.
Note
SITRANS F M Verificator
The SITRANS F M Verificator cannot be used with MAG 8000.
