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
