NGA 2000 CLD

SECTION 3 OPERATION

3-1 OVERVIEW

Once the CLD has been correctly assembled and in- stalled, the analyzer is ready for operation.

Before operating the system, verify that the Leak Checks have been performed in accordance with Section 2-4.

In this section, all operations for starting up the analyzer are explained. For more detailed information about software screens see associated Software Manual.

For the remainder of this section, Analyzer Module interconnection with a Platform or some interfacing component is assumed. Display and Keypad information refers to that which the user can expect to see and do with regard to the Front Panel of the Platform.

Depending from the software version that is installed, menu layout can change, whereas the principle of operation always stays the same.

This instruction manual is based on menus of software version 3.7.1.

3-2 STARTUP & INITIALIZATION

Apply LON connection and power to the CLD 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 button. Once power has been supplied to the Platform, the CLD Analyzer Module will be energized.

After switching on the CLD, the analyzer will begin its booting procedure which is apparent on the CLD screen. The first part of the initialization procedure is a self check of the software and analyzer components. Various displays will show the status of the initialization including revision notes, "Initializing network interface", "Search- ing for nodes", "Scanning Module 2: CLD, 12 % Com- plete", and "Calculating bindings".

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. See the Platform manual for instructions on binding combinations of mod- ules.

Pressing the F1 key during initializing will reset the CLD brightness and contrast to factory settings. Pressing the F3 softkey will abort the network initializing, aborting any connection to other analyzers. In that case, only the menus of the local analyzer will be available.

At the end of the initializing routine the "measure" screen will display. This screen is the access to all other chan- nels, menus and submenus. The actual display may differ from that shown depending on any custom configu- ration.

After the warm-up period (about one hour for the CLD Analyzer Module), all modules are completely functional. Establish that correct ozonator air pressure and sample flow rate are within specifications (see Section 1-5).Calibrate and adjust converter efficiency, and begin operation as the following sections indicate.
