Chapter 1 1.1 Introduction Use The Model HRLD Series Sensors (sensor) are compatible with applications utilizing the HIAC/ROYCO Model HR Series Sensors. Their primary use is for liquid contamination and particle size distribution analysis applications. These sensors are supported by any of the currently available HIAC/ROYCO electronic counters (such as the HIAC/ ROYCO Models 8000A, 9064, or 4100) which would be required to provide particle count and size data to the user. These sensors are designed to provide accurate measurement of particulate contamination in virtually any liquid, except certain solvents and acids. It is recommended for use with fluids with a very high level of particle contaminants, which otherwise would require dilution prior to testing. Optical/Electronic Design The sensor's optical systems are light-obscuration sensors which utilize a laser diode as the illumination source and a photodiode as the detector. Each particle passing through the sensor will generate an analog electronic pulse which is then amplified and conditioned by the internal electronic circuitry. This circuitry will utilize the light-extinction signal to automatically and continuously adjust the signal gain to compensate for variations in the background signal level. These variations occur as a result of fluctuations in the laser output power and differences in refractive index among different sample liquids. The analog pulse output of the sensor is processed by the HIAC/ROYCO counter to count and size that particle. 1-1 Version C

Chapter 2 - Installation 2.1 General This chapter will explain the installation of the HRLD Series Sensors (sensor) and its interconnection with external equipment. The documentation, which accompanies the external equipment, should be consulted for the proper mechanical and electrical connection procedures for those devices. If necessary, consult with your local HIAC/ ROYCO Service Center to resolve any questions of compatibility or suitability of this product for a specific application. 2.2 Installation The Installation subsection will cover the following topics: Inspection/Unpacking Inspection/Unpacking Positioning Standard Precautions Safety Precautions Equipment Familiarization Equipment Connections. The sensor is shipped in a single shipping carton. This carton should be retained to use in case a reshipment is required. The carton should be given a visual inspection for signs of external shipping damage. Deficiencies should be brought to the attention of the shipper. All materials received in the shipment of the sensor should be verified against the shipping papers to assure receipt of all materials. An internal inspection should made of the carton to determine if there has been damage to the contents or if items are missing. Damage to the contents should be brought to the attention of the shipper. Missing items should be brought to the attention of a representative of HIAC/ROYCO. Positioning The following are suggestions and requirement for the positioning of the equipment during installation: The sensor must be located adjacent to the particle counter at a distance not to exceed the length of the interconnecting communication/electrical cable. 2-1 Version C

The sensor must be located within or adjacent to each of the associated liquid sampling and/or handling equipment so that the tubing length is kept to a minimum. The sensor must not be placed in an area where it is susceptible to electronic noise and mechanical vibration. The sensor may be mounted in any plane. Provide adequate access for operation, maintenance, and testing. Standard Precautions The following are standard precautions which must be considered during the installation procedures: CAUTION The laser diode, in this device, is extremely sensitive to static charges and out of tolerance voltage variations. The connections must NEVER be made or removed with line power applied to the counter which provides power, ±15VDC to the sensor. Attach all electrical cabling before applying power anywhere in the system. Always apply power to the particle counter after power is applied to all other equipment of the system. NEVER make, or break, electrical connections when equipment is turned ON. Safety Precautions * * * CAUTION * * * It is recommended that prior to running any fluid, all tubing connections be checked by flushing clean (particle free) water through the instrument to check for leaks. Verify the compatibility of the sample with water before use.

Electrical The sensor receives its primary power of ±15Vdc from the particle counter. No operator maintenance is necessary that requires application of power to the unit. Laser Diode The sensor utilizes a Class IIIb laser diode which has a 5 mw maximum output. No access is required for the operation of or for maintenance. The sensor is certified to conform to the applicable requirements of US 21 CFR 1040.10 and 1040.11 (Radiation Control for Health and Safety Act of 1968, 42 U.S.C. 263f). As presently constructed, this sensor is designated by the Bureau of Radiological Health as a Class 1 product. As such, it will expose the operator to negligible levels of LASER RADIATION during normal operation. CAUTION Removal of the cover during operation may result in hazardous radiation exposure. The labels, graphically depicted in Figure 2-1, are placed on the sensor to state SAFETY CERTIFICATION and establish the place and date of manufacture. Figure 2-1 Sensor Safety Labels 2-3 Version C

CAUTION Removal of the covers from the sensor, at any time, by non-qualified personnel may destroy the laser diode and void any warranty. Device Familiarization The sensor is a self contained unit. The liquid connections are located at the top and bottom of the cell area of the unit. The location of the major components are provided here as a familiarization aid to the installer, refer to Figure 2-2. Input or Output Port Laser Diode & Optical Components Photodiode & ElectronicComponents Microcell Communications/Electrical Cable Figure 2-2 Typical HRLD Sensor (Not to scale) Laser Diode and optical components The laser diode and the optical components are located at the end opposite the cable entry. Photodiode and Electronic components Microcell Input/Output Ports The photodiode detector, preamp, and power regulator are located at the cable entry end of the unit. The sensor's microcell provides the mounting point for the liquid connections. The either port on the sensor microcell may be used as the inlet and outlet port.

Communications/Electrical Cable The communications/electrical cable provides the communications link from the sensor to the particle counter and sensor power from the particle counter. The cable s sensor connector is a 14 pin amphenol style connector. The sensor can be used in any plane, however the sensor must be securely mounted. It is usually mounted within the sampler. The liquid connections can be either input to the cell or output from the cell. The cell connections accommodate.25 inch OD (6.35 mm) OD fittings. 2.3 Equipment Connections The equipment connections for the sensor will be described with respect to its relationship to the external equipment making up the overall counting and sizing system. It is assumed that the external equipment has been properly positioned at the site and firmly mounted before performing any of the connections. General The overall particle counting system is generally composed of the sensor, a particle counter (Model 8000A or 9064), and a sampler (Model 3000, 3200, SDS, or ABS II). Any options or peripherals will be connected to the particle counter or sampler. The sample system and its respective tubing is the responsibility of the operator. Each of these systems should utilize.25 inch OD (6.35 mm) tubing connected to the fittings on the sensor. Shipping caps are provided for use during periods of shipping or at any time the unit is not connected into a system. The sensor's microcell should be clean, dry, and capped when not in use because non-volatile compounds, which may be present, can coat the sensor's microcell windows. This will make subsequent cleaning very difficult. Figure 2-3 identifies the connections. 2-5 Version C

Note: Flow must be in the direction of the arrow on the microcell. 2 Connect the sensor adapter fitting from the sample source to the sensor connection inlet. 2 Connect the drain or sampler/controller tubing to the sensor connection outlet (the port opposite the inlet port). 3 The microcell and sample lines should be completely flushed with clean liquid immediately after making the microcell connections. This will ensure that the sampling system will obtain accurate samples, when in use, and that there are no leaks. 4 Verify that all fittings are properly connected and leak-free. Do Not Over- Tighten any fittings. 5 For on-line applications, the HIAC/ROYCO accessory kit (P/N 690-0001) must be used.

Verify the compatibility of the sample with water before use. 2-7 Version C

Chapter 3 - Operation 3.1 General Operation An overall particle counting system is composed of a HRLD Series sensor (sensor), a sampler, and a particle counter. The sensor is a self contained unit consisting of the particle sensing and detection elements, +5 and - 12Vdc power regulator, and electronic signal conditioning elements. The sensor output provides analog pulses. The user will connect a liquid sample source to the inlet and a drain to the outlet. The liquid flow through the sensor microcell is controlled by the sampler or, if no sampler is used, a operator determined source. The sensor utilizes the principle of light-extinction (obscuration) for particle detection. The liquid sample flows through a sensor microcell where a laser beam is directed through a window at the sample. The light intensity is sensed (detected) by the light-extinction photodiode and used for automatic and continuous gain control of the sensor. When particles are present within the sensor microcell, the particles block the laser beam from the photodetector. This loss of laser light produces an electrical pulse for each particle. These pulses are proportional in amplitude to the light intensity or light extinction which is a measure of the particle size. The photodiode pulses are amplified to the signal strength expected by the particle counter and are transferred to the particle counter. The particle counter identifies the quantity and height of the pulses. A power regulator within the sensor converts the ±15Vdc power received from the counter into the appropriate potentials required for operation of the electrical and electronic circuits within the sensor. The particle counter identifies the quantity and height of the pulses by sorting the pulses into bins with predefined pulse amplitude ranges. The particle counter displays the counts and, when controlled by a host computer, transfers this information to the host via digital serial communication circuitry. 3-1 Version C

3.2 Operating Procedures The operating procedures for the sensor consists primarily of items which must be considered when performing analysis of liquid samples. The sensor will perform all of its operations automatically in conjunction with the connected equipment. The primary operating procedures will be associated with the particle counter and the sampler systems. The general operational procedures are shown below: Standard particle counters such as the HIAC/ROYCO Model 8000A or 9064, will normally be used with the sensor. When the sensor is used with the Model 8000A or 9064, the applicable calibration algorithm is interpolation (curve fit). DO NOT use the equation algorithm. When powders are to be sampled, choose an appropriate liquid medium for preparing a suspension of the powder to be analyzed. The use of a surfactant may be necessary to ensure a stable dispersion. Ultra-sonification just prior to sample analysis is recommended. When the sensor is temporarily not in use or is going to be stored, ensure that the sensor's microcell is kept clean. If the microcell is not clean and is allowed to dry, non-volatile compounds, which may be present, can coat the microcell windows thereby making subsequent cleaning very difficult. The user MUST thoroughly flush the tubing and microcell with one or more clean miscible liquids between analyses of different sample liquids. This will avoid problems associated with the presence of two or more immiscible liquids present in the sensing zone, and will also prevent the possibility of any reaction between incompatible liquids. If excessively high numbers of counts are obtained in the first channel for a clean liquid, or over concentration is detected, the microcell requires cleaning. The sensor can be cleaned by use of the microcell cleaning procedures, refer to Appendix A. The sensor microcell s dimensions (width) is very small. Care must be taken to prevent particles, whose dimensions are close to the cell s maximum cross section, from entering the sensor since a blockage will occur. The sample liquid should be kept at or near ambient temperature. Cold liquids can cause condensation of water on the outside of the microcell windows. 3-2 Version C

All liquid sample materials MUST be compatible with the components used in the sample path. DISCLAIMER This system is NOT guaranteed for use with materials which are incompatible with the sample path materials of the sensor. Using incompatible materials will be at the users risk and may void the warranty. Observe appropriate safety precautions when using potentially hazardous liquids. All operations assume that the sensor has been properly installed and that all sample lines are in place. 3.3 Operator Maintenance The procedures and information, noted in this section, are for the assistance of the operator in the maintenance of thesensor series sensors. The procedures are presented in the following subsections: Safety Precautions Cleaning 3-3 Version C

Safety Precautions Electrical CAUTION The laser diode, in this device is extremely sensitive to static charges and out of tolerance voltage variations. The connections must NEVER be made or removed with line power applied to the counter which furnishes the ±15VDC to the sensor. NEVER make, or break, electrical connections when equipment is powered-on. Optical The HRLD Series sensors utilize a laser diode which has a 5 mw maximum output. No access is required for operation or for operator maintenance. Cleaning Cleaning will be accomplished by the operator for the microcell and the external surfaces of the unit. Microcell Cleaning The following is general information on the methods and procedures to be considered when performing cell cleaning: 3-4 Version C

General Information Microcell cleaning is an activity which can be performed by the operator to maintain the system sensitivity. Circumstances which require microcell cleaning are: Routinely once each month. When a clean sample is run through the microcell and excessive counts are noted in the lower channels When over concentration indications are seen at the counter. Cell Cleaning Procedure Refer to Appendix A for the HRLD Series Sensor Cleaning Procedures. External Cleaning Always turn the POWER OFF before performance of external cleaning. Use a lightly moistened lint-free cloth or vacuum cleaner to clean the external surfaces of the enclosure. 3-5 Version C

Notes: 3-6 Version C

Appendix A Version C

Note: When performing oil applications, the sensor s flow cell (microcell) must be conditioned for use with oils. When returning to water soluble applications or cleaning functions, the sensor s flow cell must be conditioned for water. All solutions used to condition the sensor for oil to water and water to oil activities must be particle free liquids. Should any questions arise to the miscibility of a liquid and its compatibility with the sensor, contact HIAC/ROYCO Technical Support for assistance.

Appendix - A HRLD Sensor Cleaning And Maintenance Water To Hydraulic Oil Applications When going from water to oil, the following procedure must be followed. Otherwise, erroneous counts will result. 1 After flushing with clean water, flush with alcohol (typically isopropyl alcohol). 2 After flushing the sensor with alcohol, flush the sensor with freon 1 several times. 3 The sensor is now ready for oil application. Flushing the sensor with clean (particle free) oil is recommended prior to the actual sample analysis with oil. 4 For changing from oil to an aqueous applications, follow the above procedure in the reverse order, i.e., freon followed by alcohol, and then water. The basis for this procedure is that one fluid being used after the other must be miscible. Immiscibility will create droplets causing false particle counts and may coat the cell s windows. General Cleaning Information The HIAC/ROYCO HRLD Series Sensors are rugged high performance precision instruments that require proper maintenance to provide satisfactory service. The core of this sensor is called the microcell, which contains a precisely calibrated fluid passage slit. Mounted at a right angle to the fluid passageway is a laser diode (illumination source) and on the side of the microcell opposite the laser diode is a photodiode (detector). Light from the laser diode passes through a very small, precisely sized window in the microcell, through the fluid within the microcell, and out through a second window before falling on the photodiode. The amount of light reaching the photodiode is determined by the alignment of the illumination source and by the particles in the fluid contained in the sensor. 1 If freon is not available, petroleum ether or stoddard solvent may be used. Version C A-1

Troubleshooting HRLD Sensors Problem Cause Solutions Sampler stalls Viscosity is too high. The sensor microcell is clogged. Dilute the sample with a miscible solvent (e.g. kerosene). Using caution not to exceed the sample's flash point and flammability specifications, warm the sample. Un-block the sensor microcell. Baseline Hi error message Sample is too dark. The sensor microcell is clogged or dirty. Dilute the sample. Clean the sensor microcell. Hi noise level, with clean fluids, but no sample flow Sensor microcell is clogged or dirty.

Clean the sensor microcell. Clean the sensor microcell. A-2

Operational Errors And Solutions Operating errors that may occur are: 1 Fluids that are left in the microcell for extended periods of time in the sensor. Any fluid will leave a residue that will coat the windows of the microcell. As layers of this coating build up less light reaches the photodiode and the laser diode output increases to compensate for this. This will influence the life of the laser diode. The coating will also reduce the lower sensitivity of the sensor because the noise level becomes higher. Coating can cause particles to be inaccurately sized. 2 Particles that are too large are run through the sensor If particles larger than the microcell opening are run through the sensor, they become lodged in the slit and other particles build up behind them. Soon, no fluid will pass through the sensor and, often, no light reaches the photodiode. The counter will not count properly with this condition. This can also happen with irregularly shaped particles whose size is close to the width of the slit. Smaller particles can cling to the irregularly shaped particles and block the passageway. A large, oblong particle (e.g. a metal chip) can lodge in the flow passage upstream of the slit. This can cause turbulence and bubble formation. These bubbles appear as particles to the sensor and erroneous counts will result. To avoid these problems: 1 Re-circulating samples is not advisable in most situations. After a sample has been run once, it becomes contaminated by particles in tubing, bottles, and other areas. Accurate counts will not be obtained and the sensor may become blocked. 2 Never run a sample that may have particles larger than the sensor s cell width. 3 Always clean the microcell using the cleaning procedure. Version C A-3

7. After flushing the sensor microcell with the cleaning liquid, rinse the microcell with clean particle free water. 8. Install the sensor on the sampler configured in its original orientation (inlet/outlet ports). Check the system for leaks and, as necessary, prepare the sensor for oil applications. 9. Repeat this procedure, if necessary. Note: At the completion of this procedure, refer to the counter and sampler operations manuals for the proper start-up procedure. If the cleaning process has been performed three times without satisfactory results, a sensor microcell overhaul by a HIAC/ROYCO Service facility may be required. Clearing A Blocked Sensor To clear a blocked sensor perform the following sequence: 1. Remove the sensor and re-install the sensor reversing the flow path. The flush flow should be in the opposite direction of the sample flow through the sensor. 2. Flush the sensor with 20 milliliters of a clean (filtered particle free) fluid that is miscible with the sample solution in the sensor microcell. If the sampler stalls while flushing the sensor, proceed to step 4. 3. After flushing the sensor, use a clean dry filtered air jet to force air in the opposite direction of the initial sample flow through the microcell. This will help in removing loose particles that may be stuck in the microcell. After removing the blockage, proceed to the sensor microcell cleaning procedure, step 6. Caution Always follow safety procedures (safety glasses and protective clothing) when working with fluids or gases under pressure. 4. Using the sensor cleaning shim (P/N 80003108), carefully insert the cleaning probe into the outlet port of the sensor and run the probe towards the inlet port, through the microcell. This should push the blockage out of the microcell. Version C A-5

5. After the blockage is removed, re-install the sensor in the sampler with the flow path reversed (outlet port is the inlet port on the sensor) and repeat the cleaning blocked sensor procedure steps 2-3. If all these techniques do not work, contact your local HIAC/ROYCO Service Center nearest you, refer to the service directory in the front of this manual. HRLD 400 HC Sensor Cell Cleaning Procedure The standard HRLD 400 HC cleaning procedure is as follows: 1 The counter must be turned Off while performing this procedure. Note: At the completion of this procedure, refer to the counter and sampler operations manuals for the proper start-up procedure. 2 Purge the sensor of any sample and flush the sensor with a suitable miscible liquid a freon substitute. HIAC/ROYCO recommends a freon substute such as petroleum ether or Stoddard Solvent. Call your HIAC/ROYCO Service Center for the applicability of other solvents. After flushing the sensor s microcell with the freon substitute, flush the microcell with alcohol. 3 Remove the sensor from the sampler and note which end of the sensor is the inlet port. 4. Blow either clean dry filtered air or canned air through the sensor for about 15 seconds to dry the microcell. Caution If a facility air source is used to clean the sensor, verify that the facility air system does not contain suspended oil or produce water droplets that will interfere with sensor cleaning. 5. Hold the sensor up to a light and look through the fluid passageway to verify that the sensor microcell is not blocked. An un-blocked sensor microcell will present a sharp, clearly defined rectangular slit. If the microcell slit appears clogged, refer to the Clearing a Blocked Sensor procedure. A-6

6. Push the white end of the cleaning floss (P/N 660-850-0001) leader, through the DRY outlet side of the sensor microcell until the leader is seen at the inlet. It may be necessary to rotate the floss to get it past the microcell orifice and out the inlet. 7. Gently pull the floss out of the microcell inlet, until approximately two inches of the white floss leader is through the microcell. Caution 8. Pour a diluted micro solution into the sensors port cavity of the flow cell (a small squirt bottle is recommend to perform this step) until the flow cell is full of the solution. The floss must never be used dry. A diluted micro solution or DI water must always be present on the floss when it is used. Never pull the blue wax covered end of the floss through the microcell orifice. 9. Grasp the floss at each end of the microcell and run the floss in and out of the microcell 10 to 12 times, keep the floss wet at all times during this step. 10. Remove the floss from the microcell by pulling it out of the flow cell. Do not pull the blue waxed end of the floss through the cell. 11. Rinse the microcell with clean particle free water. 12. Install the sensor on the sampler configured in its original orientation (inlet/ outlet ports). Check the system for leaks and, as necessary, prepare the sensor for oil applications. 13. Repeat this procedure, if necessary. Note: At the completion of this procedure, refer to the counter and sampler operations manuals for the proper start-up procedure. If the cleaning process has been performed three times without satisfactory results, a sensor microcell overhaul by a HIAC/ROYCO Service facility may be required. Version C A-7

Clearing A Blocked Sensor To clear a blocked sensor perform the following sequence: 1. Remove the sensor and re-install the sensor reversing the flow path. The flush flow should be in the opposite direction of the sample flow through the sensor. 2. Flush the sensor with 20 milliliters of a clean (filtered particle free) fluid that is miscible with the sample solution in the sensor microcell. If the sampler stalls while flushing the sensor, proceed to step 4. 3. After flushing the sensor, use a clean dry filtered air jet to force air in the opposite direction of the initial sample flow through the microcell. This will help in removing loose particles that may be stuck in the microcell. Proceed to the Sensor Microcell Cleaning Procedure. Caution Always follow safety procedures (safety glasses and protective clothing) when working with fluids or gases under pressure. 4. Using the sensor cleaning probe (P/N 040219-01), carefully insert the cleaning probe wire into the outlet port of the sensor and run the probe towards the inlet port, through the microcell. This should push the blockage out of the microcell. 5. After the blockage is removed, re-install the sensor in the sampler with the flow path reversed (outlet port is the inlet port on the sensor) and repeat the cleaning a blocked sensor procedure steps 2-3. If all these techniques do not work, contact your local HIAC/ROYCO Service Center nearest you, refer to the service directory in the front of this manual. A-8
