AUGUST 2011 REV 8 FORWARD The Environics Series 2000 is designed to be the finest instrument available for producing highly precise blends of gases and optional Ozone. With the use of a powerful 32 bit microprocessor, user friendly software, mass flow controllers (MFC's) and our optional custom designed Ozone module we are able to give the user the power of precision without complex operation.
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 POWER CONNECTION OPERATING THE S-2000 AT AN INCORRECT LINE VOLTAGE WILL DAMAGE THE INSTRUMENT AND VOID THE MANUFACTURER'S WARRANTY. CHECK THE LINE VOLTAGE BEFORE YOU PLUG THE INSTRUMENT INTO ANY POWER SOURCE. LINE VOLTAGES BETWEEN 100-120 VAC (OPTIONAL 220-240 VAC) ARE ACCEPTABLE.
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 FRONT PANEL POWER SWITCH To turn the system on, push the power switch firmly up against the keyboard. The switch and display should illuminate and the start-up message should appear. CONTRAST The contrast knob, located on the lower left side of the front panel, is used to adjust the display for optimum viewing.
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 4.4.2 CURSOR KEYS The cursor keys, a group of arrows located in the lower right portion of the keyboard, are used to move between the different fields and cells located on the different entry screens.

Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 STATUS OUTPUT Allows the user to setup the eight status output lines. These lines can be instructed to turn on when a selected MFC, port, ozone, or a saved setup is in operation.
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 5.3.1 FIELD DESCRIPTIONS This is a display only field which indicates the MFC being commanded. All information on this line will be related to the indicated MFC. PORT The "Port" field tells the system which port should be connected to which MFC. The instrument will display an error if the selected port is not available to the corresponding MFC.
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 5.3.2 SOFT KEY DESCRIPTIONS START This soft key is used to begin the mix described on the display. If any errors are detected, the system will not allow the mix to start.
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 FLOW MODE In the concentration mode, the user enters the desired concentration of each gas and the total flow. In the flow mode, the user is allowed to control the exact flow through each MFC.
The nature of the reaction is such that when the concentration of "NO" or "O " is known, the concentration of "NO " can be determined. The Environics recommended method of Gas Phase Titration is the excess Nitric Oxide Transfer Standard Procedure (GPT-NO). When O...
Page 15
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 To perform GPT-NO on the instrument, follow the subsequent procedure: Determine the flow required by all the analyzers connected to the output. To this value, add 10 to 20% for excess so that all of the analyzers are assured of drawing NO .
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 MAINTAIN PORTS Extreme care should be taken to assure the information entered in MAINTAIN PORTS is correct. information entered here is carried throughout the system and can seriously affect the systems performance.
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 CYLINDER GAS CONCENTRATION The CGC field is where you enter the concentration of each cylinder. This can be done in either PPM or percent by using the "PPM OR %" soft key to select the mode of entry. If a cylinder contains pure gas, or a single gas component in a balance gas, the CGC is the concentration of the component (or 100% for pure gas).
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 SELECT GAS SYSTEM USER Gas Library Selection Soft Keys The SELECT GAS soft key will first display a sub-menu, giving the user the option of selecting a gas from the system or user libraries.
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 CONCENTRATION This is where the concentrations of different components are entered. The data can be entered in either PPM or percent with the use of the PPM OR % soft key. Any component containing a concentration of 0.0 will be removed from the final K-factor calculation.
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 CYL ID Use this soft key to enter a cylinder identification using the system text editor (See ENTER GAS pg. 17 for instructions on the text editor). INIT This key will initialize the COMPUTE K screen to concentrations of 0.0 and Nitrogen for the types. The cylinder identification and reference gas entries will be left unchanged.

Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 SET FLOW This field is used to enter calibration set points. These are the values the MFC was, or is to be, commanded TRUE FLOW The true flow field is where the actual flow of the associated set point, determined by a flow standard, is entered.
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 5.7.2.3 FLOW CALIBRATION DATA SWAP REGISTERS 12 "Swap Registers" are provided to allow saving additional sets of MFC flow calibration data (data). The method of saving and recalling data with these registers is through the "SWAP CAL" soft key. The user may choose not to use the swap registers unless more than one set of data is needed for an MFC.
Unlike calibrating a flow controller, the system cannot be run from this screen. When the system is first received it will have been calibrated with the Environics measurement standard at regular ozone and flow intervals. When target values are entered, the system uses the previous calibration data to determine what the system really commanded and associates it with the true data.

Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 relate them back to the ozone module flow which is typically 500 sccm, and the maximum ozone, which is typically 26 ppm at 500 sccm. For example, an Ozone setting of 1 ppm @ 13.0 slpm is equivalent to 26 ppm @ 500.0 sccm.
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 5.7.4.2 SOFT KEY DESCRIPTIONS INIT ALL The INIT ALL soft key will initialize the screen to a target and true flow of 13.0 slpm, a pressure of 24.69, and ozone values in 10 percent increments with the first point at 5 percent.
WARNING NOTE: If battery power is lost the system will have to be PROPERLY CONFIGURED before any calibration data is entered. Contact your dealer or ENVIRONICS for instructions on how to configure your system. 5.7.7.1 MFC and ADC/DAC DEVICES MFC, ADC, and DAC calibration data is the easiest to recover. First, obtain copies of all the latest calibration data.
Environics Series 2xxx Operating Manual AUGUST 2011 REV 8 AUTOMATIC SEQUENCER MODE The instrument incorporates a powerful automatic sequencer mode, which gives the user the ability to program the instrument for independent and unattended operation.
