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.
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
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.
