measuring unit itself, the entire module should be replaced and the faulty module be sent to GE
for repair.
NOTE: The MiniTPX measuring unit can only be repaired and calibrated at the factory. In case of
failure, the entire module should be replaced and the faulty module be sent to GE for repair.
6.1.3 ESD precautions
All external connectors of the module are designed with protection from ESD damage.
However, if the module requires service, exposed components and assemblies inside are
susceptible to ESD damage. This includes human hands, non-ESD protected work stations or
improperly grounded test equipment. The following guidelines may not guarantee a 100%
static-free workstation, but can greatly reduce the potential for failure of any electronic
assemblies being serviced:
•
Discharge any static charge you may have built up before handling semiconductors or
assemblies containing semiconductors.
•
A grounded, antistatic wristband or heel strap should be worn at all times while handling
or repairing assemblies containing semiconductors.
•
Use properly grounded test equipment.
•
Use a static-free work surface while handling or working on assemblies containing
semiconductors.
•
Do not remove semiconductors or assemblies containing semiconductors from antistatic
containers until absolutely necessary.
•
Do not slide semiconductors or electrical/electronic assemblies across any surface.
•
Do not touch semiconductor leads unless absolutely necessary.
•
Semiconductors and electronic assemblies should be stored only in antistatic bags or
boxes.
•
Handle all PCB assemblies by their edges.
•
Do not flex or twist a circuit board.
6.1.4 Protection from dust
The gas sampling system must be protected from dust entering the tubes, valves and other
components. In order to achieve this goal, the following measures must be taken:
•
Have the D-fend Pro water trap always connected to the module.
•
Clean and dust free working environment during all service procedures.
•
Minimize the times with any open connections in the gas sampling system.
•
Always close the open tube connections of the sampling system when not working on the
module.
WARNING Protect module from electrostatic discharge.
WARNING Module must be handled with care to prevent dust
from entering the gas sampling system.
