3-3 STARTUP & INITIALIZATION
Apply power to the CLD Analyzer Module. If it
is associated with a Platform, do this by plug-
ging 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 LCD screen. The first part of the ini-
tialization procedure is a self check of the
software and analyzer components. Various
displays will show the status of the initializa-
tion including revision notes, “Initializing net-
work interface,” “Searching for nodes,”
“Scanning Module 2: CLD, 12% Complete,”
and “Calculating bindings.”
If the user's system contains only one Ana-
lyzer Module, all system components, the
Controller Board and the network "self-install"
(bind together) during initial startup. If the sys-
tem contains more than one Analyzer Module,
the startup sequence will interrogate the net-
work to locate and identify all components on
the network. The user will have to bind appro-
priate combinations of components after the
startup sequence. See the Platform manual
for instructions on binding combinations of
modules.
Pressing the F1 softkey during initializing will
reset the LCD brightness and contrast to fac-
tory settings (See Section 3-6, page 3-11).
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 as shown on the
next page. This screen is the access to all
other channels, menus and submenus. The
actual display may differ from that shown de-
pending on any custom configuration as de-
scribed in Sections 3-7h, page 3-18 and
Section 3-7j, page 3-19.
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 page 1-4). Cali-
brate and adjust converter efficiency, and be-
gin routine operation as the following sections
indicate.

a. Routine
Operation
The CLD Analyzer Module is designed to
continuously analyze the sample stream.
Normally, it is never powered off except
for servicing or for a prolonged shutdown.
Maximum permissible interval between
calibrations depends on the analytical ac-
curacy required, and therefore cannot be
specified. Initially, the instrument should
be calibrated at least once every eight
hours. This practice should continue until
experience indicates that some other in-
terval is more appropriate.
