4.2

Start-up

Information contained in this paragraph is based on the premise that the

analyzer has been properly installed as outlined in Chapter 3.0, and that it is
in operable condition. If difficulties arise during start-up, it is probable that
some form of damage has incurred during shipment or some installation error
has inadvertently been made.

Accessory test equipment is not necessary for start-up of the 514.

However, if the analyzer malfunctions at start-up, an oscilloscope and a
multimeter will be required for troubleshooting (see Chapter 5.0). TAI
recommends that a dual trace oscilloscope be used. A dual trace oscillo-
scope will permit the operator to see two different waveforms simulta-
neously.

4.2.1 Preliminary Inspection

Before power is supplied to the analyzer, all modules should be opened

and inspected for damage or loose components. Plug-in circuit cards should
be firmly seated in their sockets. All barrier strip wiring connections must be
inspected, and user-installed wiring between units verified as being in agree-
ment with the system interconnection diagram.

Control Settings

Prior to turning on the power, the controls on and within the control

module should be positioned as follows:

Analyzers not equipped with Auto Zero

1. ON/OFF switches on OFF.

2. SPAN control preset to the setting noted in Specific Application

Data in the Appendix.

Analyzers equipped with Auto Zero

1. ON/OFF switches on OFF.

2. SAMPLE/ZERO switch on ZERO.

3. RUN/TEST switch (on timer unit within control module) in
