5,728,289 and 6,675,629; the sensors have a patent pending. AMI specializes in oxygen analysis only , so as not to dilute its expertise by trying to cover too many other fields. As a result AMI analyzers are more advanced and have more features than competitive models. -

The span calibration may be performed using standard span gases or ambient air. Unlike competitive sensors, the AMI sensor is made using a high capacity metallic body that provides long life with about twice the active ingredients of conventional sensors, but without compromised come-down time. -

RFI interference. Interconnections: Figure 2. Back panel of the 201LC. Alarm connections: The alarm connections are single pole double throw relays, i.e. Form C contacts. They are normally preset to operate as high alarms, failsafe, with no alarm delay, though they can be supplied with other settings. By failsafe is meant that the relays are powered when NOT in alarm, so that if power fails, they indicate an alarm condition. -

Cell block 2001LC Figure 3 Flow Schematic of the 201LC The analyzer expects to get a sample of gas at a pressure between 1 and 40psig. A built-in needle valve and flowmeter allow the user to control flow to 1SCFH with any pressure within this range. Higher pressure applications, or varying pressure applications, will need a regulator to control pressure. -

Calibration (Spanning) The model 201LC may be calibrated using air as the span gas, or else using a lower level gas closer to the measurement range. It is not necessary to zero the analyzer. Spanning is normally performed somewhere between once a month and once every three months, depending on the level of accuracy required. - Page 13 5. After a few seconds, the SPAN flag will go off and the new calibration value will be stored. 6. Using the external valve, allow sample gas to flow again.

- Page 14 Alarm Functionality: The model 201LC series has two alarms, with two associated relays. Normally, these are set to operate as high alarms (they go into alarm if the oxygen level goes above the set point), and to close their associated relays upon alarm. Their time delay is set to zero, and they do not latch (unless specifically requested otherwise).
- Page 15 Maintenance and troubleshooting Maintenance: The model 201LC is virtually maintenance free other than for periodic calibration and occasional sensor replacement. Periodic Calibration: The analyzer should be calibrated about once every month to obtain the best accuracy. The sensor typically declines in sensitivity by about 1% per month, so a monthly calibration is usually satisfactory.

- Page 20 The AMI analyzer is not designed as a primary safety device, that is to say it is not to be used as the primary means of assuring personnel safety. In particular it is not designed to act as a medical instrument, monitoring breathing air for correct oxygen concentration, and should not be used as such when it is the only safety device on the gas system.
