Set the ECO422D to “Primary” Sync Source and Auto Switch “Switch on
Fault.”
Add attenuation, 0.5 dB at a time, to the Primary input signal until the signal
source switches to the Backup.
Press the Reset button on the front panel and try to return the signal source
to Primary.
CHECK
-- that the Primary signal still shows an error and automatically
switches back to Backup. If the ECO422D doesn’t continue to show the
Primary signal in error after the reset, continue adding attenuation until the
Primary signal switches to Backup again.
CHECK
-- that the ECO switches between 2 and 4 dB down.
