Authenticate
The window "Authentication" is displayed. For
the first connection, the operating device and
the sensor must authenticate each other. After
successful authentication, the next connection
functions without authentication.
Enter PIN
For authentication, enter in the next menu win-
dow the 4-digit PIN. You can find this PIN on:
•
Type label support on sensor cable
•
A supplementary sheet in the sensor
packaging
Note:
If an incorrect sensor PIN is entered,
the PIN can only be entered again after
a delay time. This time gets longer after
each incorrect entry.
Connected
After connection, the sensor DTM appears.
If the connection is interrupted, e.g. due to a too
large distance between sensor and operating
device, this is displayed on the operating device.
The message disappears when the connection
is restored.
Change sensor PIN
It is recommended to change the default setting
of the sensor PIN to your own sensor PIN. To do
this, go to the menu "Additional adjustments",
menu item "PIN".

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
If the instrument is used correctly, no mainte-
nance is required in normal operation.
8.2
Measured value and event
memory
The instrument has several memories which are
available for diagnostic purposes. The data re-
main there 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
•
Meas. certainty
•
Electronics temperature
When the instrument is shipped, the measured
value memory is active and stores distance,
measurement certainty and electronics tempe-
