Introduction
The manifold system consists of a particle counter, manifold, manifold controller, and allows a
single particle counter to sample up to 32 different locations. Each sample location is connected to
the manifold by tubing up to 30 meters in length; and two tubes (one for sample and one for return
air) are connected between the manifold and the counter. The manifold routes the air from each
location to the particle counter in turn. An external vacuum pump maintains a constant airflow in the
system.
A manifold system can scan in any predetermined sequence through any or all manifold ports in any
order, skipping the unused ports. The counter and manifold are usually positioned outside the
cleanroom and may be left unattended to execute the programmed sampling routine, reducing the
need for monitoring personnel to intrude into the cleanroom to collect count data.
The control of the entire system may be assigned to a computer creating a control hierarchy wherein
the Manifold is powered, programmed, and controlled by a Manifold Controller, the Manifold
Controller is controlled by the Particle Counter, which is controlled by the computer, making the
sampling process automatic.
Particle Counter Four different particle counters are available for use as part of the
manifold system, models A2100, A2200, A2400 and A2408. All
four have two, four, five, or six particle-size channels, but have
different minimum size sensitivity. The counter's internal vacuum
pump draws a 1 cfm sample column from the manifold sample
tube. A built-in printer provides a printout of all data, present or
past. For complete details on operating the counter and for a
complete list of specifications, refer to the operating guide you
received with the counter.
Manifold
The 32-port manifold has been designed for operation only with the
particle counters listed above. The manifold/counter system provides
for random sampling at up to 32 locations through sample tubes. The
manifold is the rotary type requiring an external vacuum pump to
maintain a constant purge air flow during 32-port operation .This flow,
approximately two to three cfm, occurs in all idle tubing. Purging is
accomplished by allowing purge time for each port before counting
begins.
Manifold Controller
The manifold controller houses the control, display, and alarm electronics for
controlling the manifold. It displays sample sequence information and allows
programming of the manifold sampling sequence as well as providing
interface with the optional alarm relay module.

Applications
The A2432 Manifold System is designed to assist users in complying with various regulatory
standards set by government or industry such as Fed-Std 209, ISO etc, by monitoring particulate
levels at many locations within a facility. Pacific Scientific Instruments does not, however, have any
responsibility or authority to inform or train its customers in the adherence to these standards. Please
consult the appropriate regulations or regulatory agency to understand the applicable requirements
for your facility.

Setup
The first step for a successful installation is to design a layout of the manifold system. The
following example is intended to demonstrate how to set up a system in a cleanroom facility. On the
facility plan in Figure 1, note the selection of each sample point on the floor plan. While not all
installations will use all the examples, they are appropriate for many users. Each sampling point
should collect through an isokinetic probe, which aids in collecting a sample with a representative
distribution of particle sizes. The manifold system equipment should be located so that the system
complies with Fed Std 209E which states: “For particles in the 0.1 to 1
µ
m range and for a flow rate
of 0.028m3/min (1.0 ft3/min) a transit tube of up to 30m may be used. For particles in the range of 2
to 10
µ
m the transit tube should be no longer than 3m Under these conditions, losses of small
particles by diffusion and of large particles by sedimentation and impaction are predicted to be no
more than 5% during transit through the tube. For most applications these tube configurations and
flow conditions will be satisfactory. For special situations, more precise transit particle transit
characteristics can be calculated (see B20.8).” (Fed-Std-209E, B40.2.1).

Each tubing run should be the same length, ±20%. For example, having the manifold only 10 feet
from the nearest sampling point and 90 feet from the farthest will create imbalances in the system
which may adversely affect sampling.
Tubing Connections
The isokinetic probes you received with your order should be protected with plastic caps on the
openings, which should remain in place until they are ready to use in order to minimize
contamination . Install the isokinetic probes at the desired points, and select a position for the A2432
system equipment less than 100 feet (including vertical runs) from every sampling point. Verify that
adequate power is available for this equipment, and make sure that the counter and controller front
panels will remain accessible.
When the sample tubing is cut to length, cover the ends until ready to attach it to the equipment at
either end, to minimize system contamination. Connect the sample tubing to the isokinetic probes
and route the tubing to the manifold equipment without kinking. Any bend in the tubing can affect
the particle size distribution at the particle counter because the larger particles are heavier and may
drop out in bends or loops. Each bend radius should be no less than four inches and care should be
taken to avoid potential kinks at any point along the tubing where it is anchored to a clip or other
hold-down device. Fully support the tubing wherever possible and do not drape the tubing across any
sharp cornered objects where later heat induced sagging may cause pinching or kinking.
Connect the tubing to the manifold system equipment referring to figures 2 and 3 , following these
steps:
1. Connect all sample tubing (3/8" I.D.) to the appropriate manifold ports. If only a few
manifold ports are to be used, connect the sample tubing to ports spaced proportionately. For
example, five samples should be connected to ports 1, 7, 13, 19 and 26. This will keep the
airflow in the manifold balanced. Unused ports need to be left open to relieve the excess
vacuum load on the pump, or the relief valve on the pump must be adjusted according to the
pump manufacturers instructions. For further explanation of the airflow in the manifold, refer
to the “Theory of Operation” section of this manual.

WARNING
To avoid injury or equipment failure, the vacuum pump must be connected to facility
power in accordance with local building codes. The voltage and current required by the
vacuum pump are at lethal levels.
4. Wire the vacuum pump to line power that matches the requirements of the pump in
accordance with local electrical codes. A wiring diagram is provided in the vacuum pump
Operation Manual.
5. Check rear-panel identification label of the particle counter and manifold controller for line
voltage and frequency requirements. Verify instrument compatibility with facility power.

Terminology
Before configuring the A2432 Manifold System, it is important to clearly understand the
terminology used to describe the system and programming. The terms listed below are used
throughout this manual and are important to keep distinct.
Sampling Point – the physical place in the facility where the sample is being drawn from. Normally
an Isokinetic Probe, sometimes called an “isoprobe” is installed at each sampling point.
Port Number – the actual fitting on the front of the manifold itself where the tubing from the
sampling point is connected, numbered 01 through 32.
Scan Steps – The order of programmed sequence steps set up in the Manifold Controller by the
operator; up to 100 steps, numbered 00 through 99. These steps may or may not coincide with the
port number. For example, a sequence of scan steps may be programmed in which port number 07 is
the first port sampled by the system. In that case, the first scan step (00) would be port 07.
Cycles – the number of samples to be drawn at each port before moving to the next scan step,
programmed at the particle counter.
Locations – the number of scan steps to be used in a given sampling operation, programmed in the
particle counter. Refer to Table 2 to interpret the following example:
1. A sampling operation is set up with 5 sampling points. The sampling points are connected
to the Manifold at port numbers 01, 07, 13, 19 and 26.
2. The Manifold Controller is programmed for five scan steps (00-04) as shown in the table.
3. The number of cycles is set in the Particle Counter to 001, for one sample at each scan step.
4. The number of locations is programmed into the Particle Counter. If the number of locations
matches the number of ports used and scan steps, each port will be sampled once.
5. A number of locations may be programmed into the particle counter which does not match
the number of ports used or the number of scan steps. If the programmed number of
locations is fewer than the number of connected ports and scan steps, some ports will not
be sampled.
6. If the programmed number of locations exceeds the number of connected ports and scan
steps, some ports will be sampled more than once.

Operation
Powering Up
Turn the Manifold Controller power on, then turn on the Particle Counter; DO NOT turn the vacuum
pump on yet. The display on the Manifold Controller should momentarily flash “32” indicating all
32 ports are enabled and then display “01” indicating that the Manifold is currently at port 1, ready
to sample. If these conditions are not met refer to the troubleshooting section of this manual.
At the Manifold, the motor should be heard as the manifold performs a “home test” and positions the
internal sample pickup shoe to port 1.
Programming A Sampling Routine
Note: If the System was previously in use under external computer control, it must be released from
computer control and turned off and back on before programming may begin. Programmed sampling
routines should be retained in memory while power is off. To clear a previously programmed
sampling routine, press in turn Local (lit); Program (lit); Enable All Ports and Enter.
Default Settings – Sampling All 32 Ports
The factory default settings for sampling parameters are as follows:
Manifold Controller:
Ports 01-32 enabled for sampling
32 scan steps programmed (00-31)
Particle Counter:
Cycles set to 1, for one sample at each scan step
Locations set to 0 for continuous sampling
Sample time set to 1 minute, which draws a 1ft3sample
Hold time set to 15 seconds, the minimum when using a manifold system
These settings will cause the system to begin at port 1, take a one minute sample, move to port 2 and
wait 15 seconds before taking a one minute sample, move to port 3 and wait 15 seconds, etc.,
repeating the process indefinitely, returning to port 1 to begin a new routine after sampling port 32.
Simple Programming For Using Most, But Not All Ports
If the system is going to use most of the ports and leave only a few unsampled, simple programming
consists of telling the Manifold Controller which ports to skip instead of which ports to use. Follow
the steps below to create such a sampling routine.
1. At the Manifold Controller, (Figure 6)
verify “Local” is lit. If not, press the
“Local” button so that it is.
2. Press ↑
↑↑
↑or ↓
↓↓
↓until port to be skipped is
displayed on two digit LED display
3. Press “Skip” button and verify “Skip”
LED lights red. Pressing “Skip” again
restores the port to the sampling routine
4. Repeat steps 2 and 3 for each port to be
skipped
5. When ready to begin sampling, press
“Remote” and verify “Remote” LED is lit.

Programming a Detailed Sampling Routine
To program a more complex routine tailored to specific situation requirements, use the following
procedure. The example given uses the earlier example, wherein only 5 sampling points are used and
they are connected to manifold ports 01, 07, 13, 19 and 26. Begin with the Particle Counter and
Manifold Controller turned on and the Manifold Controller on Local mode.
1. At the Manifold Controller (Figure 8), press “Program” and verify that the 2 digit LED blinks
the scan step number (00) briefly and then displays the port number (01). This indicates that
the first scan step in the sampling routine will be port 1.
2. Press “Next” to save the programmed scan step and move to the next scan step. Verify the 2
digit LED blinks the next scan step number (01) briefly and then displays the next port
number. The port number displayed is from the factory defaults or from a previous program.
3. Press ↑
↑↑
↑repeatedly to display “07” in the 2 digit LED display. This sets the second scan step
(01) to port 7.

4. Press “Next” and verify the display blinks the next scan step (02) and displays the port
number.
5. Press ↑
↑↑
↑until the display shows “13”
6. Repeat steps 4 and 5 for the remaining 2 scan steps (03 and 04) and port numbers (19 and
26).
7. Press “Enter” to conclude programming
8. Verify programmed sequence by repeatedly pressing ↑
↑↑
↑and observing led display each
programmed port number in sequence.
9. Press “Remote” and verify “Remote” LED is lit to prepare for sampling.
Figure 8. Manifold Controller Scan Step Programming
The steps above may be repeated and modified to include a wide variety of configurations and
sequences. Port numbers need not be sampled in numerical order, and may be entered more than
once in a sequence of scan steps.
The following steps describe programming the particle counter for this sampling routine.
1. At the Particle Counter (Figure 9), press ↓
↓↓
↓until “Cycles” LED is Lit
2. Press “Program” and verify the 3 digit LED displays CYC and the 7 digit LED displays 00i.
Use the arrow keys to set the cycles to 003.
3. Press “Enter” to save Cycles setting, and verify 3 digit LED displays loc and the 7 digit LED
displays 00i.
4. Use the arrow keys to set the number of locations (as previously defined in “Terminology”).

Resetting the Default Sampling Routine
To restore all 32 ports to active sampling status, press in turn, “Local”; “Program”; “Enable All
Ports”; and “Enter” keys.
To completely reset the manifold controller to factory default settings and clear the memory of all
programming, turn the power switch on the rear of the controller to the off position, and, while
holding down the “Program” key, turn it back on.
Setting Alarm Limits
The alarm limits for the various particle size channels in the Particle Counter may be copied into the
Manifold Controller memory so that each sample point may have unique count alarm limits. Figure
10 and the following example demonstrates the steps to set alarm limits for the system, using the
sampling routine previously described under “Programming a Detailed Sampling Routine.”
At the Manifold Controller:
1. Press “Local” key, verify LED is lit. Two digit
display will briefly blink the first scan step (00)

Starting The Sampling Routine
Once the sampling routine has been satisfactorily programmed and the desired alarm limits are
copied, the system is ready to operate. Ensure Manifold Controller is in Remote and Particle
Counter is in Automatic mode. Turn on the Vacuum Pump supplying vacuum to the manifold system
and press “Run” on the Particle Counter. The Manifold will begin sampling from the first
programmed port and proceed through the sampling routine until it is complete.
Using the Alarm Module Option
Each alarm module provides a remote alarm contact for up to 17 alarms (16 port alarms plus an
"Any" alarm when one or more port alarms are on). The alarm output signals are available through a
connector on alarm module and provide latched outputs that are triggered by count alarms. The
alarm module also provides +12 V @ 2 A and +5 V @ 2 A to power relays for alarm-driven devices
when a count alarm is detected. Two alarm modules are required for simultaneously monitoring all
32 ports.

Using figures 11 and 12, connect the alarm module as follows:
1. Connect ribbon cable supplied with the alarm module from 25-pin connector on alarm
module to 25-pin "Alarm Out" connector (either 1 thru 16 or 17 thru 32) on rear panel of the
manifold controller.
2. Connect the alarm device between the applicable "+" voltage and the desired alarm number
output (1 to 16, or 17 to 32 if so connected).
3. Connect AC power cable from alarm module to facility power outlet.

To acknowledge (turn off) a remote alarm, press the “Reset Alarms” key on the manifold controller.
On some older manifold controllers, it may be necessary to press, in order, “Local,” Reset Alarms,”
and “Remote.”
