Troubleshooting Hints
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.
Warning
This procedure is to be performed only when the Model 430
Programmer is completely de-energized by removing the power-cord
from the power receptacle. Failure to do so could result in personnel
coming in contact with high voltages capable of producing life-
threatening electrical shock.
a. Ensure the Model 430 Programmer and all connected components
are de-energized by first shutting down the system and then
disconnecting the power cord from the power source.
