Teledyne M300EM Pneumatic Set Up OPT 50A, Input Gas Venting, Exhaust Outlet, Sample Gas Source

Optional Hardware and Software Teledyne API – Technical Manual - Model 300E Family CO Analyzers

5.6.2.2.Pneumatic Set Up (OPT 50A)

∙See Figure 3-2for the location of gas inlets and

Figure 5-4: Pneumatic Connections – Option 50A: Zero/Span Calibration Valves

SAMPLE GAS SOURCE:

Attach a sample inlet line to the sample inlet port. The SAMPLE input line should not be more than 2 meters long.

∙Maximum pressure of any gas at the sample inlet should not exceed 1.5 in-hg above ambient pressure and ideally should equal ambient atmospheric pressure.

∙In applications where the sample gas is received from a pressurized manifold, a vent must be placed on the sample gas before it enters the analyzer.

CALIBRATION GAS SOURCES:

A vent is required when an M700 is used with this option. However, if an M700E is used, a vent may or may not be required depending on how the M700E output manifold is configured.

SPAN GAS:

∙Attach a gas line from the source of calibration gas (e.g. a Teledyne API’s M700E Dynamic Dilution Calibrator) to the SPAN inlet at 30 psig.

ZERO AIR:

∙Zero air is supplied via a zero air generator such as a Teledyne API’s M701.

∙An adjustable valve is installed in the zero air supply line to regulate the gas flow.

5.6.2.3.Input Gas Venting

The zero air supply and sample gas line MUST be vented in order to ensure that the gases input do not exceed the maximum inlet pressure of the analyzer as well as to prevent back diffusion and pressure effects. These vents should be:

∙At least 0.2m long;

∙No more than 2m long and;

∙Vented outside the shelter or immediate area surrounding the instrument.

5.6.2.4.Exhaust Outlet

Attach an exhaust line to the analyzer’s EXHAUST outlet fitting. The exhaust line should be:

∙PTEF tubing; minimum O.D ¼”;

∙A maximum of 10 meters long;

∙Vented outside the analyzer’s enclosure.
