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 1ft

3

 sample 

 

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.
