Micropilot S FMR533 4 to 20 mA HART Trouble-shooting
Endress+Hauser 71
A272 electronics defect
amplifier
inconsistency in amplification exchange electronics
W275 electronics defect
factory setting
offset drift of A/D commuter exchange electronics
W511 no factory calibration ch1 factory calibration has been deleted record new factory calibration
A512 recording of mapping please
wait
mapping active wait some seconds until alarm
disappears
W601 linearisation ch1 curve not
monotone
linearization not monotonously increasing correct linearisation table
W611 less than 2 linearisation
points for channel 1
number of entered linearization points < 2 correct linearisation table
W621 simulation ch. 1 on simulation mode is active switch off simulation mode
E641 check calibr echo lost due to application conditions of
built up on antenna
Antenna defect
check installation
optimize orientation of antenna
clean antenna (cf. OM )
E651 - risk of overspill level in safety distance alarm will disappear as soon as level
leaves safety distance.
A671 linearisation ch1 not
complete, not usable
linearisation table is in edit mode activate linearisation table
W681 current ch1 out of range current out of range 3,8 mA to 20.5 mA check calibration and linearisation
