Promag 53 PROFIBUS-DP/-PA 9 Trouble-shooting
Endress+Hauser 119
EPD adjustment wrong P EPD FULL=EMPTY
 # 463
463 non specific UNCERTAIN
0x40
no limits
Cause:
Process error. The EPD calibration
values for empty pipe and full pipe
are identical, therefore incorrect.
Remedy:
Repeat EPD calibration, making
sure procedure is correct
