Section Revision List
As R&P instrumentation changes, so do our Operating and Service manuals. However, these changes may affect only one aspect of an instrument, while leaving the
instrument as a whole unchanged. To explain these individual changes to customers,
R&P will update only those sections of its Operating and Service manuals that are
affected by the instrument updates or improvements. As each manual section changes,
so does its revision number, which is located at the top right corner of each page of each
section.
To help customers keep track of the changes to the Partisol Model 2000 Air Sampler

Service Manual, Partisol Model 2000 Air Sampler
Section 2: Troubleshooting Guides
This section contains troubleshooting guides in the form of flow charts to aid the user
when performing diagnostics. This section should be used in conjunction with the
electrical schematics located in Section 4. Read Section 2.1 before using any of the
troubleshooting guides.
2.1. USING THE TROUBLESHOOTING GUIDES
The troubleshooting guides give the user a logical succession of steps to follow when
diagnosing a problem. Following is a list of the questions most commonly asked by
users with regard to the guides.
Revision B.000
2.1.1. W
HAT EQUIPMENT DO I NEED?
The main piece of equipment needed is a multimeter (that measures DC and AC
voltages and resistance) with at least a 4 digit resolution.
2.1.2. WHERE DO I START?
Look at the main screen of the Partisol Model 2000 Air Sampler. Any active errors
will be indicated in the upper left corner. Possible error codes are:
OK Great! You have no errors!
E Power Failure — A system power failure occurred during sampling.
F Flow Out of Range — The measured sample flow rate through the
sample filter deviated by more than 7% from its setpoint for more than
1 minute.
T Ambient Temperature Sensor — The ambient temperature sensor
was not installed correctly or indicated an invalid value. The ambient
temperature must be between -40°C and 60°C to be valid.
P Ambient Pressure Sensor — The ambient pressure sensor indicated
an invalid value. The ambient pressure must be greater than 0.4
atmospheres to be valid.
I Electronics Compartment Temperature — The temperature of the
instrument electronics compartment was outside of its usual operating range. The electronics temperature must be between -5°C and
60°C or the electronics may not operate reliably.
SECTION 2: TROUBLESHOOTING GUIDES PAGE 2-1
Service Manual, Partisol Model 2000 Air Sampler
2.1.3. I HAVE CHOSEN A FLOW CHART TO BEGIN WITH. NOW WHAT?
Now that you have chosen a particular flow chart, begin in the upper left corner of the
chart and follow the “flow” of instructions until you can go no further. These
instructions will bring you through a logical succession of steps to help you determine
where the problem is and what to do about it. Document the result of each step as it
is completed. This information is important if R&P is contacted.
Revision B.000
2.1.4. H
OW DO I CHECK A CABLE’S CONTINUITY?
Throughout the flow charts are instructions which indicate that a cable’s continuity
should be checked. You must check a cable’s continuity to verify that a particular
cable has not been damaged.
Follow these steps to check a cable’s continuity:
1) Set the multimeter so it will measure resistance (W).
2) Determine which cable you are checking and locate its corresponding connectors.
3) Refer to the interconnect diagrams in Section 4 to determine
which pins are connected from one connector to the other. (For
example, is pin 1 on one connector connected to pin 1 on the
other connector or to a different pin?)
4) Place one lead of the multimeter on the first pin on one of the
connectors and place the other lead on the corresponding pin of
the other connector. The resistance should be very close to zero
if the continuity is correct.
5) Repeat steps 2-4 for each set of pins being checked.
2.1.5. HOW DO I LOCATE A TEST POINT ON AN ELECTRONIC BOARD?
Refer to the schematic diagrams for the electronics in Section 4. A drawing of the
interface board is included in this section and test points are labeled.
2.1.6. HOW DO I FIND PIN 1?
There are four types of connectors used on the Partisol Monitor, “D”-type connectors,
ribbon cable connectors, 2-, 4- and 10-pin Molex connectors and round 3-, 4- and 6pin connectors.
SECTION 2: TROUBLESHOOTING GUIDES PAGE 2-2
Service Manual, Partisol Model 2000 Air Sampler
2.1.6.1. D-TYPE CONNECTORS
There is only one “D”-type connector used on the Partisol Monitor. It is a female, 9pin, “D”-type connector labeled “RS-232” on the front panel.
Revision B.000
2.1.6.2. R
IBBON CABLE CONNECTORS
All ribbon cable connector pins are counted the same, regardless of the total number
of pins. However, the location of pin 1 may vary. The location of pin 1 is noted within
the silk-screen on the corresponding electronic board. For example purposes, a 24pin ribbon cable connector is displayed below.
2.1.6.3. M
OLEX CONNECTORS
The Molex connectors used on the Partisol Monitor are white and have 2 pins (such
as the hub valve connector (P5) on the underside of the interface board), 4 pins (such
as the AC input connector (P2) on the interface board), or 10 pins (such as the 24V/
5V transformer connector (P3) on the interface board). The easiest way to determine
which pin is pin 1 on a Molex connector is to determine what color wire corresponds
to pin 1. You can find this information in the interconnection diagrams in Section 4.
Once you determine the proper wire color, then you can examine the connector and
find pin 1.
SECTION 2: TROUBLESHOOTING GUIDES PAGE 2-3
Service Manual, Partisol Model 2000 Air Sampler
2.1.6.4. ROUND CONNECTORS
There are three round connectors used on the back of the Partisol Monitor: a 3-pin
round connector is used for the ambient temperature sensor, a 4-pin round connector
is used for the user output, and a 6-pin round connector is used for the anemometer.

Section 3: Service Procedures
This section describes the service procedures required to maintain consistent operation of the Partisol Sampler. Additional maintenance procedures (such as cleaning the
PM-10 inlet) are contained in the Operating Manual. This section provides recommended intervals for maintenance and calibration procedures. However, when
determining your own intervals for maintenance and calibration, you must take into
account the quality assurance guidelines of your specific monitoring organization and
any special local considerations.
Maintenance Procedures Interval Reference

3.1. MAINTENANCE PROCEDURES
This section contains maintenance procedures for the Partisol Sampler. Additional
maintenance procedures (such as cleaning the PM-10 inlet) are contained in the
Operating Manual.
3.1.1. EXCHANGING THE LARGE IN-LINE FILTER
The large in-line filter prevents particulate matter from entering the sampler’s flow
controller and causing damage.
Tools Needed: Phillips screwdriver
Needle nose pliers
Materials: Large in-line filter (R&P P/N 32-002643)
