3.2 Principle of operation
Application area
The radar sensor NCR-21 is the ideal sensor
for typical applications in the water and waste
water industry. It is particularly suitable for
level measurement in water treatment, in
pump stations as well as storm water overflow
tanks. The flood-proof IP 68 housing of
NCR-21 ensures a maintenance-free
permanent operation. An integrated Bluetooth
module enables the wireless communication
with smartphone, tablet or PC.
Functional principle
The antenna of the radar sensor emits short
radar pulses with a duration of approx. 1 ns.
These pulses are reected by the product and
received by the antenna as echoes. The transit
time of the radar pulses from emission to reception is proportional to the distance and hence to
the level. The determined level is converted into
an appropriate output signal and outputted as
measured value.
3.3 Adjustment
Wireless adjustment
The adjustment of NCR-21 is carried out
via
standard adjustment instruments:
•
Smartphone/tablet (iOS or Android operating system)
•
PC/notebook with Bluetooth USB adapter
(Windows operating system)

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 measurement 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 buer in this memory
section. Additional echo curves are stored via:

The instrument features self-monitoring and
diagnostics according to NE 107 and VDI/
VDE 2650. In addition to the status messages
in the following tables there are more detailed
error messages available under the menu item
"Diagnostics" via app or PACTware/DTM.
Status messages
The status messages are divided into the
following categories:
•
Failure
•
Function check
•
Out of specication
•
Maintenance requirement
and explained by pictographs:

Abb. 31: Pictographs of the status messages
1 Failure - red
2 Outofspecication-yellow
3 Function check - orange
4 Maintenance - blue
Failure: Due to a malfunction in the instrument,
a fault message is output.
Function check: The instrument is being
worked on, the measured value is temporarily
invalid (for example during simulation).
Outofspecication: The measured value is
unreliable because an instrument specication
was exceeded (e.g. electronics temperature).
Maintenance: Due to external inuences, the
instrument function is limited. The measurement
is aected, but the measured value is still valid.
Plan in maintenance for the instrument because
a failure is expected in the near future (e.g. due
to buildup).
Information:
The status messages are always active.
It cannot be deactivated by the user.

8.4 Rectify faults
Reaction when malfunction occurs
The operator of the system is responsible for
taking suitable measures to rectify faults.
Procedureforfaultrectication
The rst measures are:
•
Evaluation of fault messages via the adjustment device
•
Checking the output signal
•
Treatment of measurement errors
Further comprehensive diagnostics options
are available with a PC with PACTware and the
suitable DTM. In many cases, the reasons can
be determined in this way and faults rectied.
Check the 4 … 20 mA signal
Connect a multimeter in the suitable measuring
range according to the wiring plan. The following
table describes possible errors in the current
signal and helps to eliminate them:

•
Exchange the
instrument or
send it in for
repair
Reactionafterfaultrectication
Depending on the reason for the fault and the
measures taken, the steps described in chapter
"Setup" must be carried out again or must be
checked for plausibility and completeness.
