9.3 Process error messages
Process errors can be defined as either “Fault” or “Notice” messages and can thereby
be weighted differently. Determination of this is done via the function matrix (see the
“Description of Device Functions” Manual).
!
Note!
The error types listed in the following correspond to the factory settings.
Also observe the information on Page 64 ff. and 94.
S
!
SIM. FAILSAFE
# 691
Simulation of response to error
(outputs) active
Switch off simulation
S
!
SIM. VOL. FLOW
# 692
Simulation of volume flow active Switch off simulation
S
!
DEV. TEST ACT.
# 698
The measuring device is being
checked on site via the test and
simulation device.

Type Error message / No. Cause Remedy / spare part
Type Error message / No. Cause Remedy
P = Process error
$ = Fault message (with an effect on the outputs)
! = Notice message (without an effect on the outputs)

EMPTY PIPE
# 401
Measuring tube partially filled or
empty
1. Check the process conditions
of the plant
2. Fill the measuring tube
P
!
ADJ. NOT OK
# 461
EPD/OED calibration not possible
because the fluid's conductivity
is either too low or too high.
The EPD/OED function cannot be
used with fluids of this nature.
P
$
FULL = EMPTY
# 463
The EPD/OED calibration values
for empty pipe and full pipe are
identical, therefore incorrect.
Repeat calibration, making sure
procedure is correct
