7.4

Visual examination

A visual examination of the analyzer is recommended as the next step in failure diagnosis if
the BIST fails to identify the problem.

 DANGER

ELECTRIC SHOCK

The analyzer operates using mains voltage that is dangerous to life. Make sure that the
power ON/OFF switch at the rear of the panel is set to OFF and the power cable plug is
removed.

The analyzer MUST be earthed using a grounded three core cable suitable for the rating
defined in the General Characteristics (

Table 1-3

).

Death or personal injury may result if this is not observed.

Procedure

1. Power down the analyzer and allow it to cool.
2. Visually examine the exterior of the analyzer for signs of damage.
3. Perform a visual inspection of the electrical and gas connections on the rear panel of

the analyzer.

4. If any loose connections are found tighten as required.

7.5

Failure diagnostics

If the BIST and the visual examination fail to identify the fault, perform the failure
diagnostics and recommended actions.

7.5.1
