7 TROUBLESHOOTING
Troubleshooting
52
Whenever a fault occurs refer to the tables below for help in identifying fault
causes with likely remedies to fix the fault causes. There are two kinds of faults 1)
global or system faults and 2) process related faults. Global faults can occur at any
time whereas process faults only occur at certain steps in the test process that do
not function properly. Note that fault histories can be reviewed on the fault history
page.
When a fault occurs, the controller system stops all processes. To recover from a
fault, press the Abort/Reset button. The system will then proceed though the
recovery process back to a ready state.
