Operational Configuration
There are several configuration factors that will influence the initial installation of your ACO-4500. The following
guidelines outline a typical example.
Power
The ACO-4500 will automatically switch to the Primary inputs whenever it loses power. So, you should connect the
Backup SRG-4500 and one mains input on the ACO-4500 to the same power source, and connect the Primary
SRG-4500 (and the second mains input on the ACO-4500) to a second power source. In these configurations, both
power connections would have to fail before you lose control of the ACO-4500.
Signals
You should now configure the ACO-4500 according to your requirements, namely the number of channels to be
monitored, and the signal type associated with each channel (using the procedures detailed in the previous Initial
Configuration section of this manual). When finished, remember to exit the Menu system properly to save your
settings in non-volatile memory.
When selecting the number of channels, you must always start from number 1, and continue up to the number of
signals you wish to monitor. You should set any unused channels to “No Measurement”. If you select more active
channels than you have signals connected, “Input Missing” errors will always be reported, leading to inconsistent
operation.
You can now connect your signals to the ACO-4500 rear panel BNCs according to the configuration settings made
in the previous paragraph. The example in
Figure 5.2 shows six channels from the list of supported signal types but
does not illustrate Molex® channels. Note that the maximum is 12 channels.
Figure 5.2 Example of ACO-4500 Connections
You should produce a master reference sheet, in order to log how each channel is configured and connected (an
example is shown below in
Table 5.1 ). This will be helpful to refer to in the future in order to quickly find out
whether, for example, a previously unused channel requires a menu change relating to the new signal to be
monitored.
