_PL-550 17 START UP _START UP OVERVIEWThe IQ Radar 160 has two modes of operation: run and program. When the unitis powered, after installation procedures have been completed, it is programmedto start up in the run mode, to detect the distance from the antenna flange to thetarget in meters.typical displayThe unit can be placed into the program mode at any time; to alter a number ofprogram parameters in order to better suit the application or user’s preferences.Programming can be carried out locally via the hand programmer or remotely viathe optional Dolphin/RS-485 interface. hand programmer RS-485
PL-550 18 START UPThe first step in programming is to ensure that all parameters are at their factorysetting. 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- spanThere are a number of other program parameters that can be changedsubsequently or during another programming session. Refer to ParameterDescription for a list of the parameters available.When programming has been completed, the IQ Radar 160 can be put into runby pressing or exiting Dolphin.

_PL-550 27 OPERATION __OPERATION OVERVIEWIQ Radar 160 is a process material level measuring device using advanced pulseradar technology. The device emits a series of radar pulses and analyses thereflection to calculate the material level.The device consists of an enclosed electronic component, mounted to a flangedantenna component. The electronic component generates a 5.8 GHz radar signalwhich is directed to the antenna, a Teflon® dielectric rod coupled to the core of thedevice’s mounting flange.The radar signal is emitted axially from the antenna and propagates along thisaxis in a defined conical beam decreasing in strength at a rate inverselyproportional to the square of the distance.Radar reflection is based on the dielectric constant and planar property of thematerials encountered and thus radar is very suitable for still (non-agitated) liquidsand slurries. Radar is immune to temperature and atmospheric conditions andvariations in the vessel. In an ideal application, echoes from stratified vapours areeither non-existent, or minimal compared to major echoes from the processmaterial. Where atmospheric conditions are such that dielectric constants andstratifications are of significance, their echoes can compete with the desiredreflection from the process material, making the application troublesome.The series of echoes from the pulses transmitted are sensed by the antennaduring the receive period of the electronics. The echoes are stored as a profile ofthe activity in the vessel. The profile is analysed and the distance of the materialsurface to the radar antenna is determined. This distance is used as a basis fordisplay of material level and mA output.
PL-550 28 OPERATIONTRANSCEIVERThe IQ Radar 160 transceiver operates under 1 of 5 sets of preset conditions(P003), summarized as follows:parametervalue measurementresponse echoverification filter fail-safetimer1 0.1 m/min slow on on 1002 1 m/min • on on 103 10 m/min • on on 14 100 m/min • off on 0.15 1000 m/min fast off off 0When the echoes are received, the relevant echo extraction technique (P820) isapplied to determine the true material echo.The measurement response limits the maximum rate at which the display andanalog output respond to changes in measurement. It is of concern especiallywhere liquid surfaces are in agitation or falls into the radar path during filling.
_PL-550 29 OPERATION __BLANKINGNear blanking (P800) is used to ignore the zone in front of the antenna wherefalse echoes (e.g. ladder rung) appear as an echo during the receive cycle. This isusually indicated by an incorrect high level reading and can be overcome byincreasing the near blanking from its factory set value.Far end blanking is a feature that ignores the zone below the zero or empty levelwhere false echoes can appear at levels that interfere with the processing of thetrue echo.In applications where the zero level is above the bottom of the vessel and it isdesired to monitor the zone below the normal zero, range extension (P801) canbe used to extend the range into the far end blanking. Range extension isentered as a percentage of P006. As range extension reduces the protectionafforded by the far end blanking, it should be used judiciously. Avoid excessiverange 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 areappearing ahead of the blanking zone, P006 should be reduced accordingly. false echo false echo true echo (level)0levelend oftransmit far end blankingrange extension(P801) as % P006empty distance to antennaP006Typical receiver signal P800 near blankingTypical receiver signalrange
PL-550 30 OPERATIONLOSS OF ECHOA loss of echo occurs when the IQ Radar 160 deems that the calculatedmeasurement 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 orpoor grounding. Refer to Troubleshooting. If the condition persists for a timebeyond the limit as set by the fail-safe timer (P070), the confidence icon changesfrom full to partial and the reading and mA output are immediately forced to thefail-safe default (P071).Upon receiving a reliable echo, the loss of echo condition is aborted (icon returnsto full) and the reading and mA output return to the present level immediately.
_PL-550 31 OPERATION __ANALOG OUTPUTThe IQ Radar 160 can be programmed to provide an analog output (P200) of 0 to20 or 4 to 20 mA, and for proportional or inverse span.ProgrammingUpon entering the Program mode, the analog output level holds its prior value.RunThe analog output responds in the following manner:*reference value only. mA level limited by near blanking.0 and 100% are percentage of full scale reading (m, cm, mm, ft, in)Level(P001=1)Space(P001=2)Distance(P001=3)0/4 – 20 mA(P200 = 1 or 2) 20 – 0/4 mA(P200 = 3 or 4)
PL-550 32 OPERATIONFail-safeWhen the fail-safe timer (P070) expires, the mA output responds as follows:Fail-safe Mode (071) Status0/4 - 20 20 - 0/4high 22 0/2low 0/2 22hold hold holdRUN / PROGRAMWhen the IQ Radar 160 changes from run to program, the transceiver stopsoperating and the unit no longer responds to the process. The last measurementis stored and the associated reading and mA output are held.As a courtesy, the unit reverts to the parameter last addressed during the previousprogram session.Upon return to run, the transceiver resumes operation. The reading and mAoutput default to the last measurement taken. The reading and associatedoutputs migrate to the current process level at a rate controlled by themeasurement response (P003).
_PL-550 33 OPERATION __APPLICATION EXAMPLEThe minimum distance from the antenna face to the targetis limited by the near blanking, P800.The application is to obtain a level measurement and corresponding 4-20 mAoutput proportional to material levels in a chemical tank. The antenna flange is5 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 about1 m/min. In the event of a loss of echo, the IQ Radar 160 is to go into fail-safe lowafter 2 minutes. reset:P999 master resetprogram:P001 enter ‘1’ mode of measurement = levelP002 enter ‘1’ material = liquidP003 enter ‘2’ measurement response = 1m/min.P004 enter ‘240’ antenna = dielectric rod, standard lengthP005 enter ‘1’ units = metresP006 enter ‘5’ empty distance = 5 mP007 enter ‘4.5’ span = 4.5 mP070 enter ‘2’ fail-safe timer = 2 min.P071 enter ‘2’ fail-safe = lowrun: press run to start normal operation Empty(P006)Span(P007)

If the reading bounces around an average value, select aslower rate. In general, reliability is traded for speed. Noisy applicationsor those with agitators tend to be more manageable at slower responserates, as these make use of filtering, echo verification and longer fail-safe delay.Select P003 for a measurement response just faster than thegreater 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 echostarts until the fail-safe default (P071) is effected.The P003 preset timer value can be overridden byP070.entry:measurement response echoverification filter f-s timer(P070)1 = 0.1 m/min slow on on 1002 = 1 m/min • on on 103 = 10 m/min • on on 14 = 102 m/min • off on 0.15 = 1020 m/min fast off off 0
