reaction
M022.041
Electronic Temperature Out
of Limits
The electronics temperature underranges the
permissible lower limit value. Error in the
current circuit for scanning the temperature.
The electronics should be replaced as soon
as possible.
None
The temperature of the electronics exceeds
its upper limit value. Error in the current
circuit for scanning the temperature.
M024.036
Power Supply Warning The energy supply of the device is close to
the lower permissible limit.
Check the voltage on the connection
terminal block and for values outside of the
valid range check the external energy
supply.
None
The energy supply of the device is close to
the permissible high limit.
M026.024
NV Electronic Memory Burn
Error
Writing to non-volatile memory was not
successful.
The electronics module should be replaced
as soon as possible.
None
M028.018
NV Sensor Memory Burn
Error
Writing to non-volatile memory of the
measuring cell was not successful.
The measuring cell should be replaced as
soon as possible.
None
M030.020
Electronic Interface Error Data exchange between measuring cell and
electronics is faulty.
Switch transmitter off and back on again.
Check whether error persists. If yes, replace
electronics module as soon as possible.
None
S038.044
Binary Output max
Frequency reached
The process works outside of the range. The setting of the binary output must be
compared with the process conditions.
None
S040.045
MV Input Value out of
Range
Differential pressure input value outside of
the range.
Check the value of the differential pressure. None
Static pressure input value outside of the
range.
Check the value of the static pressure.
Temperature range outside of the range. Check the value of the temperature.
S044.043
MV Calculation out of
Range
Flow is outside of the range. Compare the settings of the multivariable
configuration with the process conditions.
None
The volume flow is outside of the range.
The heat flow is outside of the range.
The calculated fill height is outside of the
range.
The volume is outside of the range.
The mass is outside of the range.
