8. Verify the installation as follows:
a. Disconnect signal inputs to the ECO8000 Series to simulate errors. Verify
a proper source switch.
b. Cycle power on the primary sync pulse generator to verify a switch to the
backup source. Repeat on the backup sync pulse generator.
c. Remove power input to the ECO8000 Series to verify correct operation.
d. Cycle power to the entire system to verify correct operation after power
is restored.
9. Configure event reporting. (See page 34, Configure event reporting.)
Once you have connected the signals, you need to configure each channel you
have connected and disable any unused channels. Use the Main menu to select
a channel and then press the ENTER button to enter the CHANNEL menu for
that channel.
Use the CHANNEL menu to enable/disable the channel, to enable/disable the
channel from triggering a changeover if the signal crossed the threshold level, to
set the threshold level, and to assign a label to the channel as an aid in identifying
the signal connected to that channel (See page 62, CHANNEL menu.).
Verify the signal margin. Once you have configured the channels, use the PRI VS
THRES and the BACK VS THRS readouts in the DIAGNOSTICS submenu
to verify that you have set the thresholds to the proper levels (See page 89,
DIAGNOSTICS submenu.).
Terminate the HREF outputs. If the HREF/Relay board outputs are not terminated,
it will change the level readings in the DIAGNOSTICS submenu on the selected
channel (primary or backup). (See page 89, DIAGNOSTICS submenu.) The
unselected primary or backup channel is terminated in the ECO8000 Series, but
the selected primary or backup channel drives through to the output. Be sure
to connect the channel output to the actual load during setup to insure proper
configuration.
