Installation

Model 3190Z

 

 

 

External Probe: The receptacle for the analysis unit cable is located in the lower left-hand corner of the rear panel. The 6-pin Minifit ™ connector is keyed to fit only one way into the receptacle; do not force it. The other end of the cable consists of four separate wires. These should be connected to the terminal strip on the analysis unit as follows:

Red:

#1

White:

#3

Black:

#2

Green:

#4

Refer to the Final Assembly, located at the back of the manual.

3.4 Gas Connections

Gas connection instructions depend on the specific external probe used and any special requirements of the process being monitored.

The standard Model 3190Z External Probe has inlet and outlet

fixtures only. Calibration gases must be externally piped into the sample inlet through appropriate valves. Quarter-inch tube fittings are used. For metric installations, quarter-inch to 6 mm adapters can be supplied.

In general, sample flow and pressure must not create significant backpressure past the sensor. For the standard probe, 2 SCFH (1 LPM) is the nominal recommended flow rate.

The pressure required will depend on the sampling system. The simplest method of pressure regulation is venting the outlet directly to atmosphere. If venting into a system of varying pressure, some form of pressure regulation is required.

3.5 Installation Checklist

Before connecting the instrument to a power source and applying power, make sure you have:

Correctly installed the sample and exhaust gas lines

Checked for leaks

Set the sample pressure to 5-10 psig nominal

Once the above checks have been made, you can apply power. The instrument is now ready for operation.
