C H A P T E R 6 G e n e r a l C a r e , T r o u b l e s h o o t i n g a n d S e r v i c e This chapter is written for a service technician with skill in both electronics and mechanics.
Table 6-1 Maintenance Schedule Maintenance Frequency Remove the cyclone cover and clean interior surfaces 100 hours of operation or as needed (especially the wall opposite the inlet nozzle). Check/clean the charger electrodes. 100 hours of operation Clean the column and outer electrode. 500 hours of operation Clean the high voltage column and sensing electrodes.
C l e a n i n g a n d R e p l a c i n g C h a r g e r N e e d l e s If you receive an error code (Tables 6-2 and 6-3) identifying a problem with either the positive or negative charger current or voltage, you will need to clean or replace the electrode in the charger head.
4. The negative charger is located closest to the top of the charger column (Figure 6-3). Remove the second set of screws (3) using an Allen wrench (provided in the accessory kit). Loosen all screws ½ turn, then remove each completely and put them aside for reassembly. Figure 6-3 Remove the Screws of the Negative Charger Assembly 5.
6. As you lift the charger head, note the honeycomb flow straightener. The “honeycomb” may be dislodged, it may stay inside the charger assembly, or it may stay inside the column. If the honeycomb remains in the charger assembly or inside the column, use a needle nose tweezers to remove it (Figure 6-5).
Page 105
Figure 6-6 The Charger Needle 9. Use a fine-tipped pair of tweezers, to gently grab the contaminated needle and draw the tweezers up, using care not to bend the needle as you do so. Do not use solvents to clean the needle. If the needle bends, use the tweezers to straighten it.
Figure 6-7 Hold the Flange with Tweezers 4. Screw a new charger wire/cone tip (provided in the accessories kit) onto the charger stem. A tweezers or pliers may be needed to hold the flange with holes to keep it from turning. Tighten the charger wire/cone tip so that it is bottomed-out and tight.
Cleaning or Replacing the Positive Charger Needle W A R N I N G High voltage is accessible in several locations within this instrument. Make sure you unplug the power source to the instrument before performing maintenance procedures. The procedure for cleaning or replacing the positive charger needle is nearly identical to that for the negative charger needle, with the following exceptions: ...
Figure 6-9 Remove the Screws of the Positive Charger Assembly C l e a n i n g t h e C h a r g e r C o l u m n The charger column should be cleaned according to Table 6-1 or when an error code indicates there is a problem.
Basic Charger Column Cleaning Procedure Note: Because of the height of the EEPS spectrometer, it is easiest to work on the instrument when it is on the floor. Protect your back—because of its weight, always use two people to move the instrument. Perform the basic charger column cleaning as follows: 1.
Unclip the wiring harness retainer using a flat-blade screwdriver, if needed (Figure 6-11). The charger wiring harness should now be free. Figure 6-11 Unclip the Wiring Harness Retainer Lift the charger head assembly off. It seals with an O-ring, so there will be some resistance as you lift the head assembly.
10. Using the cleaning tool with cloth, clean the inside of the cylinder by slowly inserting the tool into the space between the inner and outer column (Figure 6-13). Rotate the tool (in the direction which will not unwrap the cloth) and slowly push it down. Continue this motion until the cleaning tool has bottomed out at the bottom of the column.
Detailed Charger Column Cleaning Procedure Note: This procedure is easier to perform on a surface that is approximately waist high. Most of the steps in this procedure can be done by one person, but several steps may require assistance. W A R N I N G High voltage is accessible in several locations within this instrument.
8. Remove the two column retaining screws (Figure 6-15). Figure 6-15 Remove the Column Retaining Screws 9. Disconnect the electrometer ribbon connector (Figure 6-16). Use caution. Pull the connector straight out so as not to damage the pin connectors (note the use of an ESD wrist strap). Figure 6-16 Disconnect the Electrometer Ribbon Connector 10.
Figure 6-17 Disconnect the Sheath Air Hose 11. Disconnect the pressure transducer tube (Figure 6-18). Figure 6-18 Disconnect the Pressure Transducer Tube at the Column 12. The four screws that hold the base of the outer column in place are covered by the heater wrapped around the outer column.
13. Unplug the heater cable connector (red cable) from the contact on the main board. Figure 6-19 Column Assembly Base Screws 14. Use assistance for this step. CAREFULLY lift the outer column straight up and out of the instrument chassis. Take care not to scrape the inner and outer columns together.
15. Move the column assembly to a clean work surface as in Figure 6-20. Figure 6-20 Move the Outer Column Assembly to a Clean Work Surface 6-18 Model 3090/3090AK Engine Exhaust Particle Sizer Spectrometer...
16. Although the inner column should not be dirty since the electric field repels all particles, the inner center column can now be cleaned using a soft, dry, lint-free cloth (Figure 6-21). Wipe the column using a clockwise motion, not up and down. If the accumulated particles cannot be removed with the cloth, try using a cloth dampened with acetone.
17. Clean the inside rings of the electrometer assembly using a soft, dry, lint-free cloth (Figure 6-22). Wipe the rings using a clockwise motion, not up and down. If the accumulated particles cannot be removed with the cloth, try using a wet cloth (distilled water first; if that does not remove the particulates, try acetone).
R e p l a c i n g t h e F i l t e r C a r t r i d g e s W A R N I N G High voltage is accessible in several locations within this instrument. Make sure you unplug the power source before removing the cover or performing maintenance procedures.
Pump Filters To replace the pump filters, proceed as follows: 1. Locate the blue pump filters; refer to Figure 6-23. 2. Select one filter for removal and mark both ends of the tubing so you can install the new filter with flow in the proper direction. Note the orientation of the filters and direction of flow indicated on the filters.
R e p l a c e t h e E x t r a c t i o n P u m p Remove the left side panel of the instrument (see above) and locate the extraction pump as shown in Figure 6-24. Figure 6-24 Extraction Pump Location (inside back panel) Replace the pump as follows:...
T r o u b l e s h o o t i n g Baseline Noise As the instrument becomes dirty, the noise level on all channels may gradually drift up. This can be seen when there is a considerable signal even when sampling filtered air.

In this dialog, press the Zero the Electrometers button to start the zeroing. From the Front Panel of the instrument select Menu|User Settings|Zero Electrometers. Preferably, this should be done with a filter on the inlet. However, during the zero measurement, the positive charger is turned off and the negative charger is turned on at full power which generally serves the same function if it is inconvenient to attach a filter inline.
Figure 6-26 Electrometer Offset Values Noisy Channels The most common problem with the EEPS spectrometer is that one or more electrometer channels become dirty or contaminated with material. This causes the channels to indicate a signal even when filtered air is sampled by the instrument.
If the size distribution looks strange with filtered air, a good way to check if it is caused by a noisy channel is to collect the raw electrometer data. This can be done by selecting View|Instrument Status from the menu. This is a good screen to check on whether any instrument parameters are out of range (indicated by a yellow background for a reading).
problem may be that this value will not be stable over time so even if it is reset to zero, it may drift over time. Note: When the Data Type is changed from Concentration to Electrometer Current (and back), a command is sent to the instrument by the software to change this mode.
Figure 6-30 Raw Electrometer Data After Cleaning Following cleaning, the raw electrometer channels should look more like Figure 6-30 (note different y-axis scale) with data fluctuating somewhere around 10 fA or less at 0.1 second resolution. Another important consideration is that the instrument is properly warmed up for at least 10 minutes after being powered off and back on.
Error flags in Table 6-3 indicate fatal errors occurred and the associated data points cannot be used. The data points show zero (0) in a graph, but the actual data values are saved in the file. Exported data points for a given time period are set to exactly zero to indicate the invalidity of the data points.

A P P E N D I X B T h e o r y o f O p e r a t i o n The Model 3090 Engine Exhaust Particle Sizer (EEPS ) spectrometer builds on a tradition of TSI electrical-based measurements including the Electrical Aerosol Analyzer (EAA 3030) and Electrostatic Classifier (3071, 3080/3081/3085).
Rather than using a unipolar charger, a very stable and predictable Krypton-85 radioactive bipolar charger was used (3,4). When combined with a Condensation Particle Counter (CPC), the DMA can be stepped through various voltages, to detect different particle sizes (5-9). Using a computer, the voltages can be automatically stepped to generate a particle size distribution.
Figure B-2 Schematic of EEPS Measurement Column Charger The charging of the aerosol is accomplished through two unipolar diffusion chargers. First, a negative charger puts a negative net charge on the particles to reduce the number of highly positive charged particles and to prevent overcharging in the second charger.
Flow Path After passing through a 1µm cut cyclone, the aerosol enters the charger at 10 L/min and close to atmospheric pressure (see Figure B-3). It then passes through the charging region where it receives a predictable charge. In the charger, 0.6 L/min of clean air is added to the flow to keep the charger electrode clean.
