Microwave Pulse Switch - Presence & Absence DetectionMANUALRev 1.0Principle of OperationREMOTE SYSTEMThe Hawk Microwave Pulse Sender-Receiver RemoteSystem is comprised of three electrically isolated units:-the Sender, Receiver and Amplifier. The sender-receiverunits are mounted facing each other. For best performanceit is essential that they be mounted securelyand correctly aligned.The sender emits a burst of microwave energy towardthe receiver, which is designed around a tuned microwavedetector. This burst of energy is transmittedapproximately 200 times each second. While the line ofsight is interrupted by a sufficiency reflective or absorbentmaterial the energy will not reach the receiver, andtherefore the receiver will not detect the transmission.The receiver is designed to switch a relay when it’sdetector changes state. Time delays between detectorchange and relay switching is set via two single turnpotentiometers; there is a potentiometer for the make(signal detected) delay and another for the break (signalinterrupted) delay. In each case the relay will switch onlyafter the detector state has been maintained (since it’schange) for the respective time: any further change ofstate during a time-out period will override the previouschange.The sensitivity of the detector is adjusted by a potentiometer.By this adjustment, compensation can be made forpartially reflective or partially absorbing materials. Similarly,it can be adjusted so that it will change state whenonly a fraction of the beam is blocked. There are twosensitivity adjustment potentiometers, one for a coarseadjustment and the other for a fine adjustment.In the Amplifier unit there are three LED lamps; one indicatesthat power is applied, another indicates that a validsignal is detected, and the other indicates that the relayis energized. In the sender unit the only lamp is the oneindicating that power is applied.INTEGRAL SYSTEMThe Hawk Microwave Pulse Sender-Receiver IntegralSystem was created for process control applicationsrequiring highly reliable non-contact absence/presencemonitoring. The flexibility of the system allows for notonly point level indication, but also flow/no flow, proximitysensing, absence/presence and plug chute detection inmany different processes.The Integral system consists of the Microwave PulseSender (MPS) unit and Microwave Pulse Receiver(MPR) unit. Each unit can be powered by 115Vac/240Vac or 24Vdc, mounted by flange or 3”NPT weldmentand is provided in an SM listed NEMA 4X enclosurefor maximum flexibility.The MPS unit has one LED indicator for power and a100mA/250Vac fuse. It also has a TEST push-buttonfor ease of setup and troubleshooting. Inside the MPR,there are three LED indicators for the following: power,signal detect and relay energized indications as well as auser accessible 100mA/250Vac fuse.The MPS unit contains a tuned microwave diode thatemits a continuous stream (approximately200 burstseach second) of microwave energy towards the MPRunit. The MPR contains a tuned microwave detectorwhich will only accept signals from the MPS. When thesender and receiver are mounted in a direct line of sightand correctly aligned, the receiver will detect interruptionsof these bursts. In effect, there is a microwavebeam between the sender and receiver. While the lineof sight is clear, the MPR will detect an uninterruptedstream. When the beam is interrupted by a sufficientlyconductive material, the receiver detector will sense theinterruptions and change states. This change of detectorstates activates the relay, thus giving the basis forabsence/presence indication.Sensitivity of the receiver in the MPR is controlled by twosingle turn potentiometers: one for fine adjustment andthe other for coarse adjustment. The sensitivity adjustmentallows for compensation when monitoring partiallyconductive material. Similarly, it can be adjusted so thatit will change state when only a fraction of the beam isinterrupted.The SPDT relay of the MPR unit can be set to eitherenergize or de-energize when the beam is broken. Thisselection is made via the two-position slide switch nextto the power input terminals.The MPR unit also contains two time delays for controllingand fine tuning its relay operation: the make (signaldetected) and break (signal interrupted) adjustments.Each delay is independently adjustable by a single turnpotentiometer from 100ms to 30 seconds. The relay willswitch only after the detector state (signal/no signal)has been maintained for the time specified by the setpoint on the potentiometer. Any time there is a change inSultanstate,234theSeriestimers are automatically reset.For a more detailed list of specifications, please refer tothe Specifications section of this manual.Microwave Series

Microwave Pulse Switch - Presence & Absence DetectionMANUALRev 1.0Principle of OperationSpecifications - RemoteMDS DOPPLER SYSTEMRemote - MPA MRS/MRR MRS-H/MRR-HThe Hawk MDS series microwave doppler flow switchwas developed for use in process applications requiringhighly reliable non-contact product flow detection. Thesystem operates bysending out bursts of microwaveenergy toward the target product being monitored. Thetarget product will reflect some of the microwave energyback to the MDS system where it is processed to determineif the product is flowing.The MDS system uses the Doppler principle to determineif the product is moving by monitoring smallcharges in the reflected signal frequency. When productflow is detected, a timer is initiated and after the user settime-out period, the relay output is switched. The systemalso has adjustable sensitivity to compensate forproducts that may partially reflect the microwave energy.The SPST relay can be set to either energise or de-energisewhen product flow is detected. Three LED indicatorsare provided to indicate power, flow detection, and relayenergised status.The system is available in either an integral or remotehousing and is powered by 115Vac, 240Vac or 24Vdc.The system is housed in a FM listed NEMA 4X housingand is mounted using the standard 3 inch NPT weldmentor flange.Input Voltage:240Vac nominal, 200-270Vac acceptable, 50-60 Hz115Vac nominal, 100-130Vac acceptable, 50-60 HzAC supply line fuse: 100mA, 250VacAmplifier unit includes terminals for 24Vdc power supplyPower Consumption:MRA

Microwave Pulse Switch - Presence & Absence DetectionMANUALRev 1.0MountingGeneral Guidelines1. The microwave beam is a polarized form of energy.As such, it is necessary to align the units in the samespatial plane. If the units do not have the same orientationthe amount of received energy is diminished. At 90°to each other, the detector is blind and cannot detect thebeam. The actual angle of mounting is not relevant, solong as both the MPS & MPR have the same angle andelevation.See figure B.2. When looking for a mounting location, try to locateand mount the units flush and where minimal buildupwill occur. The system can penetrate through generousamounts of buildup of various products; however, thebetter the position, the more reliable it will operate.3. The systems energy cannot penetrate through steellinings or other conductive linings. You must cut a viewingwindow and use an appropriate weldment.4. For high vibration applications, it is necessary to isolatethe electronics to keep them from being damaged.This is accomplished using the optional 4” UHMW or teflonwindows. The microwave sender and receiver shouldbe mounted to a stable structure (I-beam, handrail) toisolate them from the vibration. Isolation shock mountscan also be provided to help isolate the electronics.See Figure C.5. For applications which exceed 140 degrees Fahrenheit(precipitators, cement cyclones, etc.), it is necessaryto use remote mounting microwaves with waveguideassemblies. This allows the electronics to be placed inan area where ambient temperatures do not exceedthe maximum allowable temperature for the electronics.Firebrick and ceramic windows are best suited for hightemperature applications. It is necessary to contact thefactory for this type of application, however, Figure D isprovidedas a general guideline for such applications.MDS Doppler System1. Mount the MDS in an area where the product flow is tobe monitored.2. Ensure there is low vibration on the mounting if theproduct flow is low.3/ Mount the MDR sender-receiver in a position wherestationary material will not build upon the sensor face.Ensure the face of the sensor is flush with the inside ofthe flow chamber. (if used in a closed environment)4. Correctly wire the MDR to the MDA as per the connectiondiagram. If extension cableis used, S and T aresingle cables. The remainder are all then combined toform a solid ground connection back to terminal labelledP.5. RV1 and RV2 must be adjusted together with thepotentiometer positional arrows both basically alignedin the same direction. They are parallel potentiometers.Begin at minimum anti-clockwise position.6. Position Lo-Hi slide switch to low position.7. Apply power to the unit. The green LED LD1 will beilluminated.8. When material is flowing at normal speed, slowly increaseRV1 and then RV2, then RV1 then RV2 etc. untilflow is detected. Flow is detected when the Red LEDLD2 is illuminated.9. The yellow LED, LD3 will be illuminated when therelay becomes energised.10. The relay energisation is timed via an ON delay andOFF delay potentiometers ON delay is the delay whenLD2 is constantly illuminated prior to the relay pulling in.When LD2 is no longer illuminated (i.e. no flow) the delaybefore the relay switches off is controlled by the OFFdelay potentiometer.11. When LD2 is illuminated increase RV1 and RV2 by afurther 15% (approx.) of the adjusted distance from thezero position. This allows for some variation in the flowindeed - the larger the percentage used the greater theflow change needed before the relay switches.12. Intermittent flow surges can be removed via the ONdelay OFF delay potentiometers13. If you increase RV1 and RV2 to maximum and LD2is not illuminated, decrease anti-clockwise back to zero.Slide the slide switch LO-HI to the Hi position and repeatthe slow step by step adjustment of RV 1 and RV2.Sultan 234 SeriesIf possible stop the flow to ensure the sensitivity (RV1and RV2) are set correctly. The time delays can bechecked without stopping the flow of the material. Thepush button on the RHS of the board is a press to testpush button. This simulates no received flow signal andconsequently you can adjust your on and off delays.13Microwave Series

Microwave Pulse Switch - Presence & Absence DetectionMANUALRev 1.0MountingSpecific ApplicationsFigure E - Mounted as Block Chute Switch1. When mounting to monitor in a flowing product suchas coal, ore or wood chips, position the microwave pathout of the direct flow stream. If at all possible, go behindthe flow stream or well in front of the flow stream.This will prevent any possibility of unwanted trips due toabnormal product flow from the conveying system. SeeFigure E.2. When mounting to monitor for absence/presenceor plugged chute conditions, the MPS & MPR must bemounted opposite each other observing correct elevationand orientation. The system should be mounted in sucha way so that as product backs up, the beam will bebroken. Refer to Figure E for an example.Receiving Unit(MPR)PRODUCT FLOW3. When mounting to monitor flow/no flow and pluggedchute conditions, one MDS and one MPS/MPR unitsmust be used. The MPS and MPR provide the pluggedchute detection and are mounted opposite each otherin the same manner as the standard plugged chutedetection arrangement. The MDS however, is mounteddirectly above the MPR unit.4. When using the system as a proximity switch, themounting arrangement is application dependent andmust ensure proper operation even under worst caseconditions.Please consult your representative or the factory forspecific mounting arrangements.5. Mounting of the Microwave Pulse system on slopedvessel walls can be accomplished using the MicrowaveAdjustable Mount. This system allows the microwavesto be mounted to a sloped surface and then adjustedhorizontally for optimum performance and operation.The adjustable mount has an integral 4” weldment withUHMW polyethylene or PTFE (teflon) window options.Also included with the bracket is a vibration isolationkit (shock mounts) to help protect the electronics fromdamage.

Microwave Pulse Switch - Presence & Absence DetectionMANUALRev 1.0System Wiring, Setup & CalibrationWiringWhile there is no interconnecting wiring required for themicrowave system, care must be taken to ensure thateach unit’s individual wiring is correct prior to applyinginitial power. Reference Figure A for specific termination’son each unit.1. The MPS is supplied with one 10mm (3/8” NPT) conduitentry hole pre-drilled in the enclosure while the MPRhas two 10mm (3/8” NPT) entry holes. The MRA hasthree 10mm (3/8” NPT) entry holes.2. The only wiring required by the MPS unit is that of inputvoltage. This is accomplished using the TS1 terminalblock and 16AWG wire or larger.3. The MPR will require relay wiring as well as inputvoltage wiring. This is accomplished using terminal blockTS1 for the input voltage and terminal block TS2 for therelay. All terminations require 16AWG wire or larger.4.The MRA is wired similarly to both MPS and MPR (seeconnection diagram for details)Setup & Initial CalibrationAfter completing the mounting and wiring procedures itwill be necessary to perform initial checks of the system.These checks include the following:1. Verify that the units are mounted securely and that theconduit entry angles and elevation are the same. Alsocheck to verify there is a clear line of sight between theSender and Receiver units.2. Ensure that all wiring is correct and that there are nobare wires protruding from the terminal connectors onthe units. Check the input supply voltages prior to connectingit to the units.Once you are satisfied with the installation, apply powerto the system and perform the following checks. If theanswer to any question is NO, then go to the troubleshootingsection of this manual.1. Is the power indicator (LD1) on both the MPS/MPR &MRA showing green?4. Toggle the relay normal/reverse switch (SW1) on theMPR. Does the relay energized indicator (LD3) go onand off with respect to the movements of SW1 ?Once you have completed the above checks, it will thenbe necessary to adjust the MPR/MRA for your particularprocess. With a clear line of sight between the Senderand Receiver, turn both potentiometers A & B fully counter-clockwise.1. The signal detect (LD2) will turn off. Slowly turn bothA & B together in a clockwise direction until the signaldetect indicator (LD2) begins to flicker. From this point,itis essential to move potentiometer A extremely slowas it is a fine adjustment. Further adjust potentiometerA clockwise just to the point where LD2 stays on steadywithout flickering.2. Next, adjust both time delay potentiometers to the 12o’clock position. Break the beam if possible. It is preferablethat this is done via the application but for initialadjustment of the delays you can simulate the beambeing blocked by depressing the TEST push-button onthe MPS unit. This will stop (interrupt) transmission ofthe beam.3. Adjust the ON DELAY to obtain the desired delayafter the TEST push-button is released. Adjust the OFFDELAY to obtain the desired delay after the TEST pushbuttonis depressed.4. Set SW1 on the MPR unit for the desired relay energizationmode. NORM will provide an energized relaywhile the signal is detected and REV will provide anenergized relay when the signal is lost.5. If the product fails to break the beam, adjust the sensitivitycounter-clockwise until the signal detect (LD2) lightgoes out, then adjust approximately 1/10 of a turn furthercounter-clockwise.If the set-up was completed without product, it may benecessary to make final adjustments with the processrunning and product moving between the Sender/Receiverunits. The hi-lo sensitivity should be left on hi.If the product fails to block the beam, you should thenrevert to the lo sensitivity setting.2. On the MPR, turn potentiometers A & B fully clockwise.Is the signal detect indicator (LD2) showing red?3. Have someone else depress the TEST push-buttonon the MPS while you watch the signal detect (LD2) onthe MPR/MRA. Does the indicator go on and off withrespect to the TEST push-button?18
