3-3 STARTUP PROCEDURE

3-4 BINDING

Introduce a suitable on-scale gas (NOT actual sample) into sample inlet.

Apply power to the PMD Analyzer Module. If it is associated with a Platform, do this by plugging in the Platform to a power source. The Platform has no ON/OFF power switch. Once power is supplied to the Platform, the PMD Analyzer Module will be energized.

If the user's system contains only one Analyzer Module, all system components, the Controller Board and the network "self-install" (bind together) during initial startup. If the system contains more than one Analyzer Module, the startup sequence will interrogate the network to locate and identify all components on the network. The user will have to bind appropriate combinations of components after the startup sequence.

After the warm-up period, approximately one hour for PMD Module, all modules are completely functional.

Enter appropriate data in the Calibration Gas List (by making the following display selec- tions: Main Menu, Expert Controls and Setup [enter security code, if necessary], Analyzer Module setup, Calibration Gas List). Also, enter appropriate values in the Calibration Parameters menu (by making the following display selections: Main Menu, Expert Controls and Setup [enter security code, if neces- sary], Analyzer Module Setup, Calibration Parameters), particularly data related to which ranges are to be zeroed together and how the Analyzer Module is expected to calibrate ranges (separately or otherwise).

The Analyzer Module will not allow the user to increase the upper limit of a range beyond the "maximum range" software setting. To change the "maximum range" value, select the following from the Main Menu: Technical Configuration Menu, Service Menu, Manufacturing Data, Analyzer Module Data. Select Maximum Range, and use the arrow keys to scroll the indicated value. The same applies for "minimum range" settings.

To achieve full coordination between Analyzer Modules and associated I/O Modules, the user must bind those components together in the System Setup portion of the Technical Configuration Menu in software.

3-5 CALIBRATION

Calibration consists of establishing zero and span calibration points. Generally, zero and span calibration should be performed on the range that will be used during sample analy- sis.

To calibrate the PMD Analyzer Module, introduce zero gas into the SAMPLE INLET, and do the following:

1.If the Multi-Analyzer Module, split Run Mode display is shown, press the DIS- PLAY softkey until the desired Analyzer's Run Mode display is acquired.

2.Press the MENUS softkey to enter the Main Menu.

3.Press the ENTER key to enter the Basic Controls menu.

4.Press the ZERO softkey to enter the Ana- lyzer Zero menu.

5.Press the ZERO softkey and wait.

6.Introduce span gas (Table 3-2 on page 3- 6) into the SAMPLE INLET.

7.Press the SPAN softkey to enter the Ana- lyzer Span menu, press SPAN again and wait.

8.Press the HOME softkey to re-enter the Main Menu.

9.Press the DISPLAY softkey for the Run Mode display.

For users of analyzers with suppressed indicating ranges, it may be desireable to calibrate the analyzer zero and span points within the suppressed range with gases in the sup-
