Theory of Operation
The PNR-2 sampling systems are designed tosample light liquid hydrocarbons. Thousands ofindividual samples are captured and combined todevelop a representative, composite sample ofthe flowing pipeline.
Operation of the sampling system centersaround the following primary components: theSample Pump, the Product Accumulator Vessel,the Electronic Control System, and thePrecharge Gas Vessel. All equipment, exceptthe probe mounted Sample Pump is mounted ina weather tight enclosure. These componentsare shown in the diagrams on the followingpages.
The system operates on a simple concept.When the system receives a closed contactsignal by others, the time delay relay control unitenergizes the pneumatic solenoid valve for threeseconds, refer to system flow schematic, page 6.Energizing the solenoid valve allows a pneumaticsignal into the actuation cylinder of the samplepump, which in turn causes the pump to stroke.When the pump strokes, a small sample isdisplaced. Once the solenoid valve is no longerenergized the sample pump plunger returns to itsnormal position. This action allows a newsample to be captured into the pump. When thesystem receives the next closed contact signal,the cycle begins again.
The purpose of the YZ light liquid hydrocarbonsampling system is to capture a representativeliquid sample of the pipeline product. In order forthe system to function properly, a pipeline prod-uct must be single phase, liquid product.
By properly adjusting both the sample size andthe sample frequency, the sample vessel will fillto 80% capacity at the end of the sample period.Once the sample period is complete, the productwithin the sample receiver is thoroughly mixedusing the power mixer. A representative samplecan then be removed from the product accumu-lator vessel using the YZ DuraSite, a DOTapproved constant pressure sample vessel, referto page 27.
After removing the remainder of the product fromthe accumulator vessel, the system is then readyfor a new sample period.
The purpose of the YZ light liquid hydrocarbonsampling system is to capture and maintain arepresentative liquid sample of the pipelineproduct. The sampled product is maintained in aliquid phase by the product accumulator vessel’sfree floating piston and the precharge gas sys-tem. In order for the system to function properly,pipeline product must be single phase, liquidproduct.

Standard System Connections
Pump InstallationThe PNR-2 sample pump is designed to bemounted directly to a threaded connection on thepipeline, figure 5. The probe tubing should be cutsuch that the tip of the probe will be located in thecenter 1/3 of the pipeline after installation. Afterthe pipeline has been depressurized, the threadson the probe body should be taped and doped andthe pump installed into the pipeline connection.
Skid InstallationThe system enclosure portion of the samplershould be located as close as possible to thesample pump. 1/4" stainless steel tubing shouldbe field routed from the Sample Pump/BalanceValve discharge (product out), figure 5, to theFive-Way Cross connection (product in),figure 6 on the enclosure. Care should be takenin routing tubing to prevent traps, long runs, etc.
1/4" stainless steel tubing should also be fieldrouted from the connection on the Sample Pumplabeled pneumatic supply, figure 5, to the sole-noid valve connection on the system enclosure(pneumatic supply to sample pump), figure 6.
CACACACACAUTION:UTION:UTION:UTION:UTION:Excessive tubing lengths should be avoided. Installationof the sample system enclosure should be as close tothe point of sample removal and the sample pump aspossible.

The purpose of the precharge system is to keepthe sampled product in a liquid phase. This isaccomplished by maintaining a prechargepressure on top of the accumulator vesselpiston. The precharge vessel provides additionalvolume to the precharge system, which mini-mizes the pressure increase within the productaccumulator as it fills.
Prior to placing the sampler into service, it isnecessary that the precharge system becharged to a pressure at least 100 psi greaterthan the product vapor pressure. For example, ifa product with a vapor pressure of 300 psi isbeing sampled, a precharge pressure of 400 psiwould be required. Servicing the prechargevessel is done using the isolation valve locatedon top of the precharge vessel. Please note thatthe valve isolates the precharge system from theatmosphere, and does not separate theprecharge vessel from the accumulator vessel.Also, the precharge vessel is shipped with 10 psiof blanket pressure. Normally this Pre-Chargevessel should only need to be filled one time atthe installation of the sampler system, as the gasis not consumed in the sampling process.
CACACACACAUTION:UTION:UTION:UTION:UTION:Take necessary precautions when working withNitrogen Vessels, as the high poressure containedwithin is dangerous Additionally, all personnelshould wear protective clothing, and use equipmentas recommended by the manufacturer during thistime. If you are uncertain about any aspect of theNitrogen Vessel itself, you should contact themanufacturer of your Vessel prior to proceeding.
Filling the Vessel1. Connect the precharge gas source (normally
nitrogen) to the isolation valve 1/4" NPT connection located on top of the precharge vessel, refer to page 40.
2. Open the isolation valve.
3. Fill the precharge vessel with gas until the pressure in the vessel is 100 to 150 psi above the vapor pressure of the product to be sampled.
4. Once the vessel is filled, close the isolation valve and remove the precharge gas source.
5. Leak test all connections between the precharge vessel and the product accumu- lator vessel.
6. Continue through the remaining procedures inthis manual.

The electronic control package provided withyour sampling system consists of a solid stateTime Delay Relay (TDR). The TDR converts acontinuous voltage signal into a 3 second volt-age output to the solenoid, everytime a contactclosure occurs. This 3 second duration allowssufficient time to stroke the sample pump andretrieve a single sample.
SAFETY NOSAFETY NOSAFETY NOSAFETY NOSAFETY NOTESTESTESTESTES• Always use extreme care when performing mainte-
nance on Sampling Systems. Always take necessarymeasures to assure that electrical classification in thearea is considered, before, and during all repairs, andthat necessary steps are taken to maintain properelectrical procedures for the classification of the area.
The control package requires you to provide24 VDC at terminals 1 and 3, refer to page 44.You are also required to provide dry contacts atterminals 3 and 6, refer to page 44, in order tostroke the pump. All electronics are housed inexplosion proof enclosures and are rated for usein Class I, Division 1, Groups C and D hazard-ous locations.

Setting Operator Input Parameters
The proportional to flow control function is actuallyperformed by the dry contact input pulse provided byanother customer owned flow monitoring device, like aflow computer. The set up of this other device must bedone in conjunction with the set up of the samplersystem in such a manner, that the proper amount ofsample will be gathered during the duration of thesample cycle, and to assure that the integrity of theproportional relationship between the gathered sample,and the flowing volume in the pipeline is maintained.
The maximum amount of sample that can be safelyplaced in the accumulator vessel is 80% of the totalvessel volume. There are two ways to arrive at thesettings for the Proportional to Flow Control.
Sampler Control Set-up Option #1This method is based on the premise that theMetered Volume per pulse value in the flowmonitoring device, is already set to a predeter-mined value by the customer.
Calculate the pump displacement setting usingthe following formula:
Pump Displacement Setting = D x E B x C
Where, B = Average Flow rate (Gal/day or BBL/day)
C = Sample Cycle (days)
D = Metered volume per pulse (Gal/pulse or BBL/pulse)
E = 80% sample accumulator volume (cc)For 1.5 gallon accumulators, E = 4,542 ccFor 3 gallon accumulators, E = 9,084 ccrefer to Example #1, figure 7.
The pump setting must be within range of 0.25to 1.8 cc / stroke, refer to section 2, page 9, forsetting the pump displacement.

PNR-2P Sample Pump & Balance Valve
The PNR-2P Sample Pump, refer to Apendix A,page 37, is a positive displacement plungerpump designed to be mounted directly on thepipeline. It has an adjustable displacement of0.25 to 1.8cc and achieves proportional-to-flowsampling through adjustment of the systemelectronic control discussed in Section 5, page 15.
As the plunger returns upward after completing astroke, the pump chamber fills with productthrough the inlet check valve. The inlet checkvalve is a dart type valve designed to seat on ano-ring. The inlet check valve is spring loaded toensure a positive seating action after everystroke. When the pump is actuated , the plungermoves downward, displacing product throughthe discharge check valve known as the balancevalve.
The Balance Valve, refer to Apendix A, page 38,automatically senses pipeline pressure andadjusts to ensure that product is not allowed tofree flow to the product vessel. When thepipeline pressure is greater than the prechargepressure on the accumulator vessel, the balancevalve dart is pushed up against the seat and thetop head of the balance valve. As the pumpstrokes, the pressure created in the pumpchamber forces the balance valve dart off theseat, allowing product to be pumped to theaccumulator vessel. Once the pump completesits stroke, the pressure across the balance valveequalizes and the dart is returned to a sealingposition by its spring.
In the event that the accumulator vesselprecharge pressure is greater than the pipelinepressure, the balance valve dart and seat arepushed apart by the product pressure in theaccumulator vessel. In this situation the checkvalve wafer located between the balance valveand the sample pump acts as a back check toprevent the escape of product previously cap-tured in the accumulator vessel. As the pumpstrokes, the pressure created in the pumpchamber forces the check valve wafer off theseat, allowing product to be pumped to theaccumulator vessel. Once the pump completesits stroke, the pressure across the check valveequalizes and the wafer is returned to a sealingposition by its spring.

Accumulator VesselThe YZ Product Accumulator Vessel, refer toApendix A, page 41, is designed to maintain acomposite sample in the liquid phase. This isaccomplished by using a free-floating pistondesign and an inert precharge gas system, referto Apendix A, page 40. As product is collectedin the accumulator vessel, the precharge gassystem maintains a constant pressure on top ofthe vessel piston. If this pressure is at least 100to 150 psi above the vapor pressure of theproduct being sampled, the sampled product willbe prevented from flashing to the vapor phase.
Product enters the cylinder through the head inthe bottom of the cylinder. This head is theaccumulator vessel product head. Theprecharge gas is communicated to theaccumulator vessel through the precharge head,which is located on the top of the accumulatorcylinder.
The actuator assembly is located on the top ofthe accumulator cylinder and serves two func-tions. The first is to provide mixing of thesampled product by moving the mixing disc upand down within the product portion of theaccumulator cylinder. This is done by introduc-ing pressure to one side of the mixer pistonassembly and then by applying pressure to theopposite side of the mixer piston assembly.
The second function of the actuator assembly isto provide indication of the amount of productcollected within the vessel. This is shown locallyon the magnetic volume scale mounted on theactuator assembly cylinder.

5-Way Cross
The Five-way Cross Assembly, refer to ApendixA, page 39, is located on the front of the skidand includes the following items: product inlettubing fitting, pressure gauge, relief valve, robvalve, accumulator vessel isolation valve/dis-charge tubing fitting, and the five-way cross.
The pressure gauge is used during normaloperation to indicate the pressure within theaccumulator vessel. During start-up andtroubleshooting procedures it is used in conjunc-tion with the accumulator vessel isolation valveto check pump performance.
The YZ relief valve is a reseating type valvewhich is factory set to relieve at 1800 psi. Alsoincorporated into the relief valve design is apositive indication feature which indicates that ithas relieved. If the system reaches a pressuregreater than the relief valve setting, the resultingrelease of product pushes the black relief valveindicator outside the relief valve body. Thisinforms the system operator during his nextsystem check that an over pressure conditionhas occurred. The indicator is reset by pushingit back into the relief valve body.
The rob valve is a YZ needle valve which is usedto remove product from the accumulator vesselat the end of the sample period. This valve isnormally closed.
The accumulator vessel isolation valve is usedto isolate the accumulator vessel from the rest ofthe product carrying portion of the samplingsystem. This valve is normally open.

Actuation/Mixing System (Pneu)
The function of the 80 psi instrument air supplyis to provide an actuation power source for thesample pump and the accumulator vessel mixingsystem, refer to Apendix A, page 43. Con-structed as an integral component of the entiresampling system, the entire system is pressuretested at the factory prior to shipment.
The instrument air source is internally connectedto individual components within the samplersystem. These split the pneumatic sourcebetween sample pump actuation and accumula-tor vessel mixing. The "actuation" leg is piped toa pressure regulator (factory set at 38 psi) andon to a three-way proof solenoid valve. Thissolenoid valve is normally closed and is mountedin the sample system enclosure. It is openedwhen energized by the sampler electroniccontrol package. Opening the solenoid valveallows pneumatic pressure to actuate the samplepump. The actuation tubing to the SamplePump from the solenoid connection must be fieldinstalled by the customer.
The "mixing" leg of the system is tubed directlyto the inlet of the accumulator mixing valve. Theinlet is located on the right side of the switch.The mixing switch is a three position switch, withthe center position being the off position. Whenthe mixing switch is moved to the up position,the mixing disc is moved up in the productaccumulator. Moving the mixing switch to thedown position causes the product accumulatormixing disc to move down in the product accu-mulator. The sample in the accumulator vesselis mixed by moving the mixing handle alternatelyup and then down. Four or fives passes throughthe sample should provide sufficient mixing.

Preparing The System for Operation
Sample Pump PrimingBefore the pump begins normal operation afterinitial installation or maintenance, the samplepump must be purged of all air in the samplechamber. The purge valve on the SamplePump/Balance Valve, refer to Apendix A, page 37,is used to evacuate the air from the chamberand to make sure the pump is liquid-packed. Ifthe pump is not purged before being placed intooperation, it will not function properly.
To purge the pump, open the purge valve lo-cated on the side of the PNR-2 Sample Pump/Balance Valve assembly. The product supplyvalve can then be opened to allow pipelineproduct to purge the air within the pump. Onceproduct begins exiting the purge valve, close thepurge valve. The sample pump is now ready tobegin operation.
Product Line TestClose the isolation valve located on the bottomof the Five-way Cross Assembly, refer toApendix A, page 39. Stroke the sample pumpuntil the system pressure reaches 1800 psi onthe Five-way Cross Assembly Gauge. Thepressure should hold steady between pumpstrokes. Once the system is at 1800 psi, leaktest all connections. Once the system has beentested, open the isolation valve located on thebottom of the Five-way Cross Assembly.
Sample Vessel ConnectionConnect a constant pressure portable samplevessel (DuraSite) to the rob valve located on theFive-way Cross Assembly, refer to Apendix A,page 39 using a short section of 1/8" or 1/4"stainless steel tubing. The portable samplevessel must also be precharged to 100-150 psiabove the vapor pressure of the product, refer topage 26. Open the rob valve allow product intothe DuraSite as the pump takes samples. Closethe rob valve and remove the sample vesselfrom the rob valve, at the end of each samplecycle, and replace it with a clean empty vesselfor the next cycle.

DuraSite Sample Vessel ConnectionPurpose: The DuraSite Portable Sample Vesselpermits the user to remove a liquid or gas hydro-carbon sample from a pipeline or a sampling de-vice. This is accomplished without changing thepressure of the product or exposing it to acontaminant fluid. If properly used and maintainedthe DuraSite will provide many years of safe, ac-curate and clean sampling.
Use: The DuraSite is a very safe device to use.As with any equipment dealing with flammableproducts, it is mandatory that a good, thoroughoperator training procedure be established priorto use.
Typical use of the cylinder would be as follows:
Step 1: (In The Lab) Connect a regulated inertgas supply to the pre-charge valve. The productvalve should be open. By carefully controlling thepre-charge valve and the regulator, the cylindercan be slowly charged with pre-charge gas(NOTE: This should be done slowly to preventslamming the piston down to the opposite end).The pressure on the pre-charge pressure gaugeshould be brought to a reading of 10-50 psi abovethe expected pressure of the product in the field .Close the pre-charge valve and disconnect thegas supply. Check the pre-charge valve, reliefdevice, and the pre-charge pressure gauge forleaks. Any leaks should be stopped before con-tinuing. The vessel should be placed in a paddedcarrying case and made ready for field use.
STEP 2: FOR COLLECTION OF SAMPLE FROMCOMPOSITE ACCUMULATOR VESSEL.
2a: Connect the product end of the pre-chargedsample vessel to the product supply. (Samplerproduct removal valve)NOTE: the pre-charge pressure gauge read-ing should be greater than the product supplypressure reading. If not, repeat Step 1 above.
2b: Once the vessel is connected to the productsupply, it is necessary to vent a small amount ofproduct prior to filling the vessel. This assuresfresh product and removes any air or gas whendealing with liquids. This can be done by loosen-ing the product purge valve a very small amountuntil the product is purged. After thorough purg-ing, the product purge valve should be tightened.
2c: The product pressure gauge reading shouldbe 10-50 psi below the pre-charge pressure gaugereading. By carefully opening the pre-chargevalve, the pressure becomes equalized, then be-gins to drop below the product pressure. The pre-charge valve should be carefully controlled so asto not vent the pre-charge gas too fast.
2d: When the cylinder becomes a maximum of80% full (see volume indicator), all valves shouldbe closed. The product connection is slowly bro-ken in order to vent any trapped product. Aftervessel removal, all connections should be checkedfor leaks and the pre-charge and product valveports capped to prevent leakage.
2e: Pack the DuraSite in appropriate carrying caseto meet D.O.T. guideline, with D.O.T. paperworkand transport to lab for analysis.
Step 3: (In The Lab) Prior to analysis, the prod-uct should be mixed. This is accomplished simplyand efficiently by inverting the cylinder end-over-end, causing the mixing ball to fall through theproduct. Approximately 10-12 trips of the mixingball through the product assures a homogenoussolution.
Step 4: The regulated pre-charge gas should bereconnected to the pre-charge side of the cylin-der. The pre-charge gas supply should remainopen during analysis.
Step 5: Purging a small amount of product fromthe vessel removes unmixed product from the tee,relief device, gauge, etc. The unit can now beconnected to a chromatograph and the productanalyzed.
Step 6: After analyzing, the remainder of the prod-uct should be dumped and the vessel properlycleaned. Normal cleaning can be accomplishedby rinsing the product end with a petroleum sol-vent and flushing with acetone. If a more thor-ough cleaning is required, the vessel should bedisassembled.
WARNING: A portable sample vessel shouldnever be filled to more than 80%. This allowsa 20% pre-charge cushion to absorb thermalexpansion of the product.
Shipping: Extreme care should be taken when pre-paring a vessel for shipment. Both valves shouldbe capped to prevent possible leakage. The ves-sel should be placed in a snug-fitting, well-paddedand durable case. All applicable DOT regulationsshould be adhered to.

Preventative MaintenanceSchedule
A preventative maintenance program serves to antici-pate maintenance issues prior to waiting until the systemrequires service. Like changing the oil & filters in anautomobile, by choosing to service the various parts andoperation in the Sampling System at regular intervals,the technician can perform the maintenance servicewhen desired, rather than when required, such as in themiddle of night.
The key is to perform maintenance before it is required.The preventative maintenance schedule implementedshould consider the application of the sampler. Many ofthese considerations include: the weather environment;the condition of, the actuation gas, the product conditionand quality, and the pump stroke frequency. All of theseissues must be considered when establishing a preven-tative maintenance schedule.

• Take special care when disconnecting any fitting, toassure that product and/or pressure will not bereleased when the connection is broken. This systemmay contain liquid and/or gas at high pressures.
Step-by-Step Resolution
Using a step-by-step method to resolve issues on theSampling System will reduce maintenance time andassist in returning the system to service quicker.
The following represent the recommended chronology toresolve issues:
Resolve issues to the following order:a. Actuation Gas Pressure, page 31b. Electrical Power, page 32c. Sample Pulse, page 33d. Pump Performance, page 34e. Pre-Charge Pressure /Product Accumulator
Vessel , page 35
Actuation Gas Pressure
This section should be used to troubleshoot samplerperformance, when the Sample Pump will not actuate,and/or when the pneumatic power mixing system on theAccumulator Vessel will not function.
Actuation Gas Troubleshooting Steps
1. Verify the supply gas valves, and regulators supply-ing gas to the sampler system are properly function-ing, and adjusted.
2. Disconnect the Pneumatic Supply connection at thetop of the Sample Pump.
a. There should NOT be any gas pressurepresent. Gas pressure should be present forONLY 3 seconds each time a sample pulse isreceived by the sample systems from the flowmonitoring device, that signals the samplerwhen to take a sample.
b. Initiate a sample with the flow monitoring devicepulse, and observe to see if a 3 second burst ofgas is expelled from the connection loosened instep 2 above.

c. If a 3 second burst of gas is expelled from theconnection loosened in step 2, the actuationsystem to the pump is functioning properly.Reconnect the Pneumatic Supply connectionto the top of the Sample Pump. Proceed topump performance troubleshooting, if theproblem seems to be with your pump, orproceed to step 3, if you are having difficultieswith the power mixing of your sample system.
3. Disconnect the tubing at the top of the ActuatorHead of the Product Accumulator vessel. Thereshould not be any pressure there until the MixingValve is placed in the down mixing position.
a. If gas is flowing continually when this line isdisconnected, the Mixing Valve should berepaired, or replaced.
b. If gas does not flow to the loosened connectionwhen the Mixing Valve is actuated to the downposition, try moving the valve to the up position,and see if you get gas flow at the loosenedconnection. If you still have no gas flow to theloosened connection, the Mixing Valve shouldbe repaired, or replaced.
c. If gas does flow properly, to the loosenedconnection, when the Mixing Valve is placed inthe down mixing position, check the vent/muffleron the Mixing Valve to see if it may be stoppedup. Clean or replace the vent/muffler as required.
Electrical Power
IMPORIMPORIMPORIMPORIMPORTTTTTANT NOANT NOANT NOANT NOANT NOTE:TE:TE:TE:TE:All electronics are housed in explosion proofenclosures and are rated for use in Class I,Division 1, Groups C and D hazardous locations.
The 24 VDC power supply to the sampler must beproperly connected and supplying power to the samplesystem, before it can be expected to perform. Oftenelectrical storms, or other electrical surges that occur atthe sampler site may cause interruption of the powersupply to the sampler. The power is used to drive thesolenoid for a duration of 3 seconds each time a sampleis called for by the flow monitoring device connected tothe sampler system. Electrical power troubleshooting willinclude steps to assure the 24 VDC power is actuallygetting to the solenoid for the required duration, and thatthe solenoid is activating the sample pump. The typicalsymptom to lead a technician to this step would be thatthe sample pump is not being actuated when a pulsefrom the flow monitoring device sends a dry contactsample pulse to the sampler.
Electrical Power Troubleshooting Steps
CACACACACAUTION:UTION:UTION:UTION:UTION:Prior to opening the electrical enclosure be sure todisconnect all power and pulse connections at the safeend of wiring or perform test to assure the area of theenclosure is safe to open the enclosure.
1. Verify the 24 VDC power is actually reaching theTDR in the Sample System electrical enclosure.
a. Test for continuous 24 VDC at the TDR byconnecting your DC Voltmeter to the TDRterminal pins #1 and #3. (Pin #1 should be theNegative connection, and pin #3 should be thePositive connection), refer to electrical wiringdocument, on page 44.

b. If there is not 24 VDC continuous power to theTDR, check the breaker, and DC wiring back tothe DC source. Repair any loose or brokenwires, reset or replace circuit breaker asrequired.
2. The next Electrical Power test is to see if the TDRfunctions properly when a dry contact pulse isapplied
a. Once continuous 24 VDC power is verified atpins #1 and #3 on the TDR, (step #1 above);Connect your DC Voltmeter to the TDR termi-nal pins #2 and #3 (Pin #2 should be theNegative connection, and pin #3 should be thePositive connection), refer to electrical wiringdocument, on page 44. This should be apulsed 24 VDC with a 3 second duration ONLYwhen the TDR is activated, by the dry contactpulse from your flow monitoring equipment.
b. If the flow monitoring device can not be utilizedto send a test pulse at this time, you may beable to create a test pulse.
CACACACACAUTION:UTION:UTION:UTION:UTION:These connections carry 24 VDC power.
Connect a normally open switch that is capableof creating a dry contact closure, and rated forthe voltage present, to pins #3 and #6 on theTDR, refer to electrical wiring document, onpage 44 Close the switch momentarily, whileyour DC voltmeter is connected as in trouble-shooting step 2a.
3. The next electrical power test has to do with thedwell time of the TDR. If the test #1 and #2 have notresolved your problem, the delay resistor on theTDR may have been damaged. The resistor isconnected to pins #4 and #5 on the TDR, refer toelectrical wiring document, on page 44. It should bea 330 K. 1 Watt resistor, YZ P/N G1-0024.
4. The final step in troubleshooting the electrical powerfor the sampler, would be to replace the TDR itself.It is available from YZ Systems by orderingP/N E0-6007.
Sample Pulse
The sample pulse is actually a contact closure thatallows one leg of the 24 VDC power in the TDR toconnect to another pin of the TDR causing the TimedDelay circuit to energize, thus sending a 24 VDC signalto the solenoid for 3 seconds. The origin of this contactpulse is in the flow monitoring equipment, that is notactually a part of the sampler system; therefore trouble-shooting will be limited to verifying that the samplersystem does respond properly when an appropriatepulse is generated.
Sample Pulse Troubleshooting Steps
CACACACACAUTION:UTION:UTION:UTION:UTION:Prior to opening the electrical enclosure be sure todisconnect all power and pulse connections at the safeend of wiring or perform test to assure the area of theenclosure is safe to open the enclosure.
1. 1st you should determine if the TDR functionsproperly when a dry contact pulse is applied.
a. Connect your DC Voltmeter to the TDRterminal pins #2 and #3 (Pin #2 should be theNegative connection, and pin #3 should be thePositive connection), refer to electrical wiringdocument, on page 44. This should be apulsed 24 VDC with a 3 second duration ONLYwhen the TDR is activated, by the dry contactpulse.
b. Disconnect the flow monitoring device, byremoving wires from the TDR pins #3 and #6,refer to electrical wiring document, on page 44.

c. Connect a normally open switch that is capableof creating a dry contact closure, and rated forthe voltage present, to pins #3 and #6 on theTDR, refer to electrical wiring document, onpage 44. Close the switch momentarily, whileyour DC voltmeter is connected to the TDRterminal pins #2 and #3 (Pin #2 should be theNegative connection, and pin #3 should be thePositive connection), refer to electrical wiringdocument, on page 44. Your volt meter shouldshow a pulsed 24 VDC with a 3 secondduration ONLY when the TDR is activated, bythe dry contact closure created above. If you donot see the 3 second pulse of electricity, gothrough the Electrical Power trouble shootingsteps again. If you do get the 3 second pules ofelectricity, proceed to checking for a brokenwire between the TDR and the Flow MonitoringEquipment, or begin troubleshooting the FlowMonitoring Equipment.
Pump Performance
There are many factors that affect pump performance.Some are within the pump, while others are outsidefactors that affect pump performance.
Pump Performance Troubleshooting Steps
1. Actual performance of the Actuation Gas, andElectrical Power issues should have already beendealt with, If not , perform those troubleshootingsteps before proceeding to step 2.
2. Close the isolation valve located on the bottom ofthe Five-way Cross Assembly. Stroke the samplepump while observing the pressure reading on theFive-way Cross Assembly Gauge. The systempressure should steadily build to 1800 psi . Thepressure should hold steady between pumpstrokes. Once the system is at 1800 psi, leak testall connections. Once the system has been tested,open the isolation valve located on the bottom ofthe Five-way Cross Assembly. Completion of thistest verifies the pump performance is O.K.
3. The next step, if the pump did not pass the test instep 2, is to verify that the pump is fully liquidpacked with liquid product to be pumped. TheSample Pump must be purged of all air in thesample chamber, before it can pump liquid product.The purge valve on the sample pump is used toevacuate the air from the chamber and to makesure the pump is liquid-packed. If the pump is notpurged properly, it will not function properly.
a. Open the purge valve located on the left side ofthe PNR-2 sample pump.
b. Next open the product supply valve to allowpipeline product to purge the air within thepump.
c. Once product begins exiting the purge valve,close the purge valve. The sample pump isnow ready to begin operation. Perform pumptest #2 again. If your product is not consistentlyin a single phase liquid state the pump willvapor lock again, and repriming will be neces-sary, repeatedly, till the phase condition of theproduct is resolved.
4. If during the pump troubleshooting step 2, youobserved the pressure on the Five-way CrossAssembly Gauge jumping from pipeline pressure toa higher pressure, during the pump stroke, butimmediately returning to pipeline pressure after thestroke, the Balance Valve Assembly should berebuilt using a YZ Repair Kit P/N D3-0137.
5. If during the pump troubleshooting step 2, youobserved the pressure on the Five-way CrossAssembly Gauge build steadily to pipeline pressure,then stop building at pipeline pressure, the SamplePump inlet check is not holding. Typically installing aYZ Repair Kit P/N D3-0152, will resolve this situa-tion.

Pre-Charge/Product Accumulator
The Product Accumulator works in conjunction with thePre-Charge Vessel to maintain the integrity of capturedsample in the sampler system. The Product AccumulatorVessel may be repaired on site, but requires somespecial tools to do so, and it is recommended that if thisvessel needs service, you should contact YZ SystemsTechnical Service @ 1.936.788.5720 to obtain a ReturnAuthorization Number to return the Product Accumula-tor Vessel to YZ for reconditioning. The pre-chargevessel pressure must remain at a pressure that exceedsthe critical vapor pressure of the product being sampled.A typical pressure setting should be 100 PSI over thepipeline pressure.
Pre-Charge/Product Accumulator Troubleshooting Steps
1. If the charge in the vessel is low, recharge it to theproper pressure, by connecting an external sourceof inert gas to the Pre-Charge Isolation Valve, andopen the valve until the Pre-Charge Vessel pressureis once again at the desired pressure.
2. Close the Pre-Charge Isolation Valve.
3. Disconnect the external source of inert gas.
4. Wrap a 1/4” MNPT plug with TFE tape, and install itin the Pre-Charge Isolation Valve.
5. Use liquid soap to leak test all connections on thePre-Charge Vessel, Pre-Charge Isolation Valve,Tubing to the Accumulator Vessel, and Pre-Chargeconnection to the Accumulator Vessel. Fix any leakdetected.
6. If no leaks were found in step 5, look at the mostrecent analysis report on product taken from thissampler, to see if an abnormal amount of inert gasof the type used for Pre-Charge was present in thesample. If Pre-Charge gas is found in the sample,contact YZ Systems Technical Service @1.936.788.5720 to obtain a Return AuthorizationNumber to return the Sample Accumulator Vesselto YZ for reconditioning.
