6 Component repair
6.1 General
6.1.1 Preparation and procedures
The following instructions assume that all equipment has been properly installed and checked, that the analyzer has been
application engineered, and that temperature controllers, alarm switches and other adjustments have been properly set.
Ensure no hazardous or flammable gases are present in the immediate area of the analyzer, as they may
create the potential for fire, explosion, and damage to property and injury to personnel.
6.1.2 Electrostatic discharge information
A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper packaging and grounding
techniques are necessary precautions to prevent damage. To prevent electrostatic damage, observe the following precautions:
•
Transport products in static-safe containers such as conductive tubes, bags, or boxes.
•
Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
•
Cover workstations with approved static-dissipating material. Use a wrist strap connected to the work surface and
properly grounded tools and equipment.
•
Keep the work area free of nonconductive materials such as ordinary plastic assembly aids and foam packing.
•
Always be properly grounded when touching a static-sensitive component or assembly.
•
Avoid touching pins, leads, or circuitry.
•
Use conductive field service tools.
6.1.3 Powering down the analyzer system
1. Obtain proper work permits such as hot work, etc.
2. Stop all analyses.
3. Turn power to the analyzer OFF.
4. Turn heater air OFF.
5. Open oven door and let oven cool to room temperature.
