Optional Equipment
Symptoms Not Indicated by Fault Messages
NOTE: Do not attempt field repairs on electronic components or assemblies
— replace the entire assembly with an operational spare. Most
electronic problems are corrected by replacing the printed circuit
board assembly (PCBA), sensor, or cable that causes the fault
indication.
The same is true of electro–mechanical failures traced to the shuttle
frame assembly or the hammer bank. Replace the entire assemblies;
they are not field repairable.
