Set the user switch (S14-8) to Normal (closed).
Power up all instruments.
Enable the front panel, using the Front Panel button.
Set the ECO422D to “Switch on Fault” using front-panel buttons. (This is the
default at power on.)
If Primary is not already the source, press the Sync Source button to make
Primary the source. (This is the default at power on.)
Note that the output signal is the Primary input signal (black burst without setup)
and that none of the fault indicators light.
Press the Sync Source button to change to the Backup source.
Note that the signal changes to black burst with setup (Backup).
Check that there is no error indicated for either signal.
Press the Sync Source button again, to switch back to the Primary input.
Disconnect the Primary signal source. (Remove the cable between the BG7 and
the Primary 1 input of the ECO422D.)
Note the signal automatically switches to the Backup input and the Primary fault
indicator lights.
Reconnect the Primary signal source. (Replace the cable between the BG7 and
the Primary 1 input of the ECO422D.)
Note that the Primary fault indicator remains on and the Sync Source remains the
Backup (the ECO422D does not automatically switch back to Primary).
Press the Reset button.
Note that the Primary fault indicator turns off.
Press the Sync Source button to return to the Primary as the source.
Press the Auto Switching button to disable the “Switch on Fault” function.
Remove the Primary input signal. (Again, remove the cable between the BG7
and the Primary 1 input of the ECO422D.)
Note that no switching occurs, but that the Primary fault indicator lights.
Press the Sync Source button to change to the Backup signal.
Press the Sync Source button again to try to change back to the Primary input. (It
should not let you change to a bad input.)
