Parameter adjustment

Prerequisites
For parameter adjustment of the instrument
via a Windows PC, the configuration software
PACTware and a suitable instrument driver
(DTM) according to FDT standard are requi-
red. The latest PACTware version as well as all
available DTMs are compiled in a DTM Collec-
tion. The DTMs can also be integrated into other
frame applications according to FDT standard.

Maintenance

Maintenance
If the device is used properly, no special mainte-
nance is required in normal operation.
Cleaning
The cleaning helps that the type label and mar-
kings on the instrument are visible.
Take note of the following:
•
Use only cleaning agents which do not cor-
rode the housings, type label and seals
•
Use only cleaning methods corresponding
to the housing protection rating
8.2 Measured value and event
memory
The instrument has several memories available
for diagnostic purposes. The data remain there
32
even in case of voltage interruption.
Measured value memory
Up to 100,000 measured values can be stored
in the sensor in a ring memory. Each entry con-
tains date/time as well as the respective measu-
red value. Storable values are for example:
•
Distance
•
Filling height
•
Percentage value
•
Lin. percent
•
Scaled
•
Current value
•
Measurement reliability
•
Electronics temperature
When the instrument is shipped, the measured
value memory is active and stores distance,
measurement reliability and electronics tempe-
rature every 3 minutes.
The requested values and recording conditions
are set via a PC with PACTware/DTM or the
control system with EDD. Data are thus read out
and also reset.
Event memory
Up to 500 events are automatically stored with a
time stamp in the sensor (non-deletable). Each
entry contains date/time, event type, event de-
scription and value. Event types are for example:
•
Modification of a parameter
•
Switch-on and switch-off times
•
Status messages (according to NE 107)
•
Error messages (according to NE 107)
The data are read out via a PC with PACTware/
DTM or the control system with EDD.
Echo curve memory
The echo curves are stored with date and time
and the corresponding echo data. The memory
is divided into two sections:
Echo curve of the setup: This is used as
reference echo curve for the measurement
conditions during setup. Changes in the measu-
rement conditions during operation or buildup
on the sensor can thus be recognized. The echo
curve of the setup is stored via:
•
PC with PACTware/DTM
•
Control system with EDD
•
Display and adjustment module
Further echo curves: Up to 10 echo curves
can be stored in a ring buffer in this memory
section. Additional echo curves are stored via:
