Teledyne 300 Options, Rack mount with slides, Zero/span valves, In Internal Overheating

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 Zero/span valves

The Zero/Span Valve option consists of three stainless steel solenoid valves mounted inside the Analyzer connected to admit sample gas or customer-generated zero air or span gas.

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

A Zero air manifold should supply gas in excess of the 800 cc/min +10% demand of the Analyzer. The zero manifold should be connected at the IZS/Zero Air fitting on the rear of the Analyze and should be vented to the outside atmosphere.

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 30-35 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.
