Troubleshooting Hints
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.
b. Remove the Model 430 Programmer top cover and check all fuses
for continuity.
c. If a fuse is bad, replace with a fuse of identical rating:
Caution
Installing fuses of incorrect values and ratings could result in
damage to the Model 430 Programmer in the event of component
failure.
c. Replace the fuse and securely fasten the Model 430 Programmer
top cover. Reconnect the power-cord.
4. Verify the input voltage selector switch on the Model 430
Programmer printed circuit board is in the proper position for the
available input power. Checking the input voltage selector requires
removal of the top cover of the Model 430 Programmer. Observe the
same safety procedures as presented in step 2, above.
