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 67 and 109.
Type Error message / No. Cause Remedy
P = Process error
$ = Fault message (with an effect on the inputs and outputs)
! = Notice message (without an effect on the inputs and outputs)
Nr. # 4xx
→ Process limits exceeded
P
$
EMPTY PIPE
# 401
Measuring tube partially filled or
empty
– Check the process conditions
of the plant
– 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

> BATCH TIME
# 471
The maximum permitted
batching time was exceeded.
1. Increase flow rate
2. Check valve (opening)
3. Adjust time setting to changed
batch quantity

>< BATCH QUANTITY
# 472
– Underbatching:
The minimum quantity was not
reached.
–Overbatching:
The maximum permitted
batching quantity was
exceeded.
Underbatching:
1. Increase fixed correction
quantity.
2. Valve closes too quickly with
active after run correction.
Enter smaller after run as
mean value.
3. If the batching quantity
changes, the minimum batch-
ing quantity must be adjusted.
Overbatching:
1. Reduce fixed correction
quantity.
2. Valve closes too slowly with
active after run correction.
Enter larger after run as mean
value.
3. If the batching quantity
changes, the maximum batch-
ing quantity must be adjusted.
