contact an AMI Technical Support Representative for assistance. Refer to
“Additional Technical Support” on page 148.
5.2.1 Electrostatic Discharge Precautions
The system contains components which are susceptible to damage by
Electrostatic Discharge (ESD). Take the following precautions whenever
the cover of electronic equipment is removed.
1. Disassemble only in a static-free work area.
2. Use a conductive workstation or work area to dissipate static
charge.
3. Use a high resistance grounding wrist strap to reduce static charge
accumulation.
4. Ensure all plastic, paper, vinyl, Styrofoam ® and other static
generating materials are kept away from the work area.
5. Minimize the handling of the system and all static sensitive
components.
6. Keep replacement parts in static-free packaging.
7. Do not slide static-sensitive devices over any surface.
8. Use only antistatic type desoldering tools.
9. Use only grounded-tip soldering irons.
10. Use only static-dissipative hand tools (pliers, cutters, etc.).
5.2.2 The Model 430 does not appear to be energized
1. Ensure that the Model 430 Programmer is energized from a power
source of proper voltage.
Warning
If the Model 430 Programmer is found to have been connected to
an incorrect power source, return the instrument to AMI for
evaluation to determine the extent of the damage. Frequently,
damage of this kind is not visible and must be determined using
test equipment.
2. Verify continuity of all line fuses (F1, F2, F3, F4, F5, F6 and F7)
located on the Model 430 Programmer printed circuit board.
