7.3 Setup System - Setup Inputs
The AC8 has eight digital input points that may be configured
individually. These inputs may have a wide variety of Liebert or other
manufacturers’ equipment connected for monitoring.
To configure a digital input:
Log In and Choose Setup System
• From the Main Menu, use the arrows
↑↓ to choose System and
Control, then press Enter ↵ (see 7.1 - Login for help).
• Enter your password at the Login screen.
• From the System and Control Menu, use the arrows
↑↓ to choose
Setup System, then press Enter ↵.
Select a Digital Input to Configure
• From the Setup System Menu, shown at right, use the arrows
↑↓ to choose Setup Inputs and
press Enter ↵.
• From the Select Input Menu, choose the input you want—for example, Device_1—and press
Enter ↵.
Table 15 shows the digital input features you may change, along with the default settings: you may
change the name of the input, define it as Normally Open or Normally Closed, and specify it as alarm-
able or as an event.
• Alarmable inputs may be defined as either Unlatched or Latched.
• Event status allows you to monitor a digital input’s state—and use a change in state to initiate an
action through an output, if desired—without triggering an alarm. Events are always Unlatched.
• You may also specify a time delay before the AC8 responds to an alarm or event.
Use the steps following Table 15 to change the default settings for any digital input.
