Power-up Tests
What happens at power-up
When power is applied, the controller will run several diagnostic tests,
including RAM test, EEPROM test and Slidewire calibration test. After
these tests are completed, “Success” is displayed.
Failsafe Failures
If one or more of these tests fail, the controller will go to the Failsafe
Manual Mode, and FailSafe will flash in the diagnostics display and a
message indicating which test failed will appear in the dianostics
display.
