The IQ Radar 160 has two modes of operation:
run
and
program
. When the unit
is powered, after installation procedures have been completed, it is programmed
to start up in the
run
mode, to detect the distance from the antenna flange to the
target in meters.
typical display
The unit can be placed into the
program
mode at any time; to alter a number of
program parameters in order to better suit the application or user’s preferences.
Programming can be carried out locally via the hand programmer or remotely via
the optional Dolphin/RS-485 interface.

START UP
The first step in programming is to ensure that all parameters are at their factory
setting. The quickest way is to perform a master reset, P999.
For a Quick Start, P001 to P007 are the key parameters requiring entry.
They set: - mode of measurement
- process material
- antenna configuration
- measurement response
- units
- empty distance
- span
There are a number of other program parameters that can be changed
subsequently or during another programming session. Refer to Parameter
Description for a list of the parameters available.
When programming has been completed, the IQ Radar 160 can be put into
run
by pressing or exiting Dolphin.

OPERATION
OVERVIEW
IQ Radar 160 is a process material level measuring device using advanced pulse
radar technology. The device emits a series of radar pulses and analyses the
reflection to calculate the material level.
The device consists of an enclosed electronic component, mounted to a flanged
antenna component. The electronic component generates a 5.8 GHz radar signal
which is directed to the antenna, a Teflon® dielectric rod coupled to the core of the
device’s mounting flange.
The radar signal is emitted axially from the antenna and propagates along this
axis in a defined conical beam decreasing in strength at a rate inversely
proportional to the square of the distance.
Radar reflection is based on the dielectric constant and planar property of the
materials encountered and thus radar is very suitable for still (non-agitated) liquids
and slurries. Radar is immune to temperature and atmospheric conditions and
variations in the vessel. In an ideal application, echoes from stratified vapours are
either non-existent, or minimal compared to major echoes from the process
material. Where atmospheric conditions are such that dielectric constants and
stratifications are of significance, their echoes can compete with the desired
reflection from the process material, making the application troublesome.
The series of echoes from the pulses transmitted are sensed by the antenna
during the receive period of the electronics. The echoes are stored as a profile of
the activity in the vessel. The profile is analysed and the distance of the material
surface to the radar antenna is determined. This distance is used as a basis for
display of material level and mA output.
PL-550 28
OPERATION
TRANSCEIVER
The IQ Radar 160 transceiver operates under 1 of 5 sets of preset conditions
(P003), summarized as follows:
parameter
value measurement
response echo
verification filter fail-safe
timer
1 0.1 m/min slow on on 100
2 1 m/min • on on 10
3 10 m/min • on on 1
4 100 m/min • off on 0.1
5 1000 m/min fast off off 0
When the echoes are received, the relevant echo extraction technique (P820) is
applied to determine the true material echo.
The measurement response limits the maximum rate at which the display and
analog output respond to changes in measurement. It is of concern especially
where liquid surfaces are in agitation or falls into the radar path during filling.
_
PL-550 29
OPERATION _
_
BLANKING
Near blanking (P800) is used to ignore the zone in front of the antenna where
false echoes (e.g. ladder rung) appear as an echo during the receive cycle. This is
usually indicated by an incorrect high level reading and can be overcome by
increasing the near blanking from its factory set value.
Far end blanking is a feature that ignores the zone below the zero or empty level
where false echoes can appear at levels that interfere with the processing of the
true echo.
In applications where the zero level is above the bottom of the vessel and it is
desired to monitor the zone below the normal zero, range extension (P801) can
be used to extend the range into the far end blanking. Range extension is
entered as a percentage of P006. As range extension reduces the protection
afforded by the far end blanking, it should be used judiciously. Avoid excessive
range extension as this can reduce the measurement’s reliability and accuracy.
Range extension is factory set for 20% of P006. If it is found that false echoes are
appearing ahead of the blanking zone, P006 should be reduced accordingly.

OPERATION
LOSS OF ECHO
A loss of echo occurs when the IQ Radar 160 deems that the calculated
measurement is unreliable, i.e. the confidence (P805) is less than the threshold
(P804). This can be due to such circumstances as high level of electrical noise or
poor grounding. Refer to Troubleshooting. If the condition persists for a time
beyond the limit as set by the fail-safe timer (P070), the confidence icon changes
from full to partial and the reading and mA output are immediately forced to the
fail-safe default (P071).
Upon receiving a reliable echo, the loss of echo condition is aborted (icon returns
to full) and the reading and mA output return to the present level immediately.
_
PL-550 31
OPERATION _
_
ANALOG OUTPUT
The IQ Radar 160 can be programmed to provide an analog output (P200) of 0 to
20 or 4 to 20 mA, and for proportional or inverse span.
Programming
Upon entering the Program mode, the analog output level holds its prior value.
Run
The analog output responds in the following manner:
*reference value only. mA level limited by near blanking.

OPERATION
Fail-safe
When the fail-safe timer (P070) expires, the mA output responds as follows:
Fail-safe Mode (071) Status
0/4 - 20 20 - 0/4
high 22 0/2
low 0/2 22
hold hold hold
RUN / PROGRAM
When the IQ Radar 160 changes from
run
to
program
, the transceiver stops
operating and the unit no longer responds to the process. The last measurement
is stored and the associated reading and mA output are held.
As a courtesy, the unit reverts to the parameter last addressed during the previous
program session.
Upon return to
run
, the transceiver resumes operation. The reading and mA
output default to the last measurement taken. The reading and associated
outputs migrate to the current process level at a rate controlled by the
measurement response (P003).

PL-550 33
OPERATION _
_
APPLICATION EXAMPLE
The minimum distance from the antenna face to the target
is limited by the near blanking, P800.
The application is to obtain a level measurement and corresponding 4-20 mA
output proportional to material levels in a chemical tank. The antenna flange is
5 m from the tank bottom. The empty level is 0 m (bottom) and the full level
(span) is 4.5 m from the bottom. The maximum rate of filling or emptying is about
1 m/min. In the event of a loss of echo, the IQ Radar 160 is to go into fail-safe low
after 2 minutes.

PARAMETER DESCRIPTION
P002 material
Optimizes measurement reliability for target type.
entry: 1 = liquids, fluids or flat surfaces
P003 measurement response
Collectively sets a number of operating parameters that determine the
maximum rate of change in target range that the reading and mA
output can keep up to.
If IQ Radar 160 cannot keep up with the rate of level change, select a
faster rate. If the reading bounces around an average value, select a
slower rate. In general, reliability is traded for speed. Noisy applications
or those with agitators tend to be more manageable at slower response
rates, as these make use of filtering, echo verification and longer fail-
safe delay.
Select P003 for a measurement response just faster than the
greater of the maximum filling or emptying rate.
echo verification: discriminates between agitator blades in motion or
spurious noise, and the target surface (true echo).
filter: discriminates between false echoes from constant
acoustical or electrical noise and the target surface.
fail-safe timer: establishes the period from the time a loss of echo
starts until the fail-safe default (P071) is effected.
The P003 preset timer value can be overridden by
P070.

verification
re-locate IQ Radar 160
Reading ‘EEEE’ reading too large re-program
ie. empty distance P006
or span P007
Reading response slow P003 setting increase response if
possible
Reads correctly but
occasionally reads high
when vessel is not full
detecting close range
echo increase blanking
High level reading lower
than material level material is within near
blanking zone decrease blanking P800
