3.Parts Per Million (PPM) and Percent Oxygen indicators: the PPM light will

light while the instrument is measuring O2 in units of PPM. The percent light will light while the instrument is measuring O2 concentration in percent.

4.Flow Indicator and Flow Set: a flowmeter and flow set knob are provided for adjusting gas flow in standard cubic feet per hour (SCFH).

5.Liquid Crystal Display (LCD) with keypad: the LCD shows system menus and data during instrument operation. The keypad is the primary user-input device used to enter information in the system.

3.3Rear Panel

Figure 3–1 also shows the rear panel of the 3160. Located on the rear panel are the following electrical power and gas input ports, alarm relay outputs, and analog and digital outputs:

1.Gas Input/Vent: three input fittings are provided for span gas, sample gas, and compressed air for pneumatic valve operation. A single vent is used for the sample and span gas outlet. Consult the Appendix for scrubber selec- tion.

2. AC Power Input: 110, 120, 220 or 240 V ~ at 50/60 Hz 1.5 A MAX.

Use 250 V 1.6 A T Fuse for 110, 120 V ~

Use 250 V 0.8 A T Fuse for 220, 240 V ~

3.Alarm Circuit Connections: there are five contact closures/openings provided for external alarms. The alarm functions are defined by the user via keypad input within the LCD menu system.

4.Analog Outputs: four analog output connectors are provided for use with a chart recorder. Two provide range and data in voltages; the other two provide range and data for current-driven recorders.

5.RS-232 Serial Port: a 9–pin digital input/output connector is provided for connecting either a serial printer or a serial link to an external computer. Optional serial link software (such as TRACS) can be used with the instru- ment for remote external computer monitoring and control of the instrument, via modem or hardware link.
