7.3 Setup System - Setup Inputs
The Liebert 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 Login on page53 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 7.2 on the facing page 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 alarmable 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 Liebert AC8 responds to an alarm or event.
Use the steps following Table 7.2 on the facing page to change the default settings for any digital input.
