Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A

1.8 Options

1.8.1 Rack Mount With Slides

This option, including slides and rack mounting ears, permits the analyzer to be mounted in a standard 19" wide x 30" deep RETMA rack.

NOTE

A 1¾ minimum separation between each instrument must be

maintained to allow for air circulation. Blocking the air inlet vent on

the bottom of the analyzer will result in internal overheating.

1.8.2 Span Valve

The Span Valve option consists of stainless steel solenoid valve mounted inside the analyzer connected to admit sample gas or customer-generated span gas.

The valve is controlled from the front panel push-buttons, the auto-timer via the RS-232 interface, or by remote contact closure.

A span gas manifold should supply at least 1000 cc/min. The manifold should be vented to the outside atmosphere away from the personnel.

A span gas manifold can be connected to the analyzer in either of two ways.

1.If it is desired to use span gas directly from a pressurized source (e.g. a gas cylinder) the connection can be made directly to the Pressure Span port on the analyzer rear panel. In this case the Vent/Span port at the rear panel should be vented to a suitable exhaust manifold at ambient atmosphere pressure. The pressure regulator on the gas source (cylinder should be sent to provide 20 - 25 PSI delivery pressure).

2.If it is desired to use span gas from a source which delivers gas at atmosphere pressure (e.g. a calibrator), the span gas manifold should be connected at the Vent/Span port at the analyzer's rear panel, and the Pressure/Span port should be capped.
