Possible cause
The electronics or the measuring cell have been
replaced, but replacement mode has not been
executed.
The electronics or the measuring cell has been
replaced and replacement mode for a new
measuring cell must be executed.
The electronics or the measuring cell has been
replaced, replacement mode has been activated,
but in the wrong direction (SW 2 = 0).
The electronics temperature underranges the
permissible lower limit value. Error in the current
circuit for scanning the temperature.
The temperature of the electronics exceeds its
upper limit value. Error in the current circuit for
scanning the temperature.
The energy supply of the device is close to the
lower permissible limit.
The energy supply of the device is close to the
permissible high limit.
Writing to non-volatile memory was not
successful.
cell was not successful.
Data exchange between measuring cell and
electronics is faulty.
Differential pressure input value outside of the
range.
Static pressure input value outside of the range. Check the value of the static pressure.
Temperature range outside of the range.
Recommended measure
Execute replacement mode: Place switch SW 1 of the electronics
in position 1 = activate replacement mode. With switch SW 2
select whether measuring cell or the electronics have been
replaced. Switch device off and on. Return switch SW 1 of the
electronics to position 0.
Execute replacement mode: Only the data of the electronics can
be copied into the measuring cell. Place switch SW 1 on (1) to
activate replacement mode 1 - with switch SW2 select new
measuring cell (1). Switch device off and on. Place switch SW 1
on (0) to deactivate replacement mode.
Change replacement direction (if possible). Switch SW 1 is
already in position (1), replacement mode is activated. Switch
SW 2 to position (1) for new measuring cell . Switch device off
and on. Place switch SW 1 is position (0) to deactivate
replacement mode.
The electronics should be replaced as soon as possible.
Check the voltage on the connection terminal block and for
values outside of the valid range check the external energy
supply.
The electronics module should be replaced as soon as possible.
The measuring cell should be replaced as soon as possible.
Switch transmitter off and back on again. Check whether error
persists. If yes, replace electronics module as soon as possible.
Check the value of the differential pressure.
Check the value of the temperature.
