Liebert Universal Monitor 用户手册

The Setup System screen displays seven options that allow you to configure input and output 

devices and their relationships, the common alarm, the modem, pagers to be dialed when alarms 

occur, and a variety of system details, such as login password and system date and time:

• Setup Input
• Setup Common Alarm
• Setup Sensor
• Setup  I/O  Matrix
• Setup Output
• Setup Modem & Pagers
• Setup System Info
• Setup Exp Board

The Universal Monitor has eight digital input points that may be 

configured individually. If the optional Expansion Board is used, an 

additional 16 digital inputs may also be configured. These inputs may 

have a wide variety of Liebert or other manufacturers’ equipment 

connected for monitoring.
To configure a digital input:

• From the Main Menu, use the arrows

↑ ↓

 to

 

choose System and 

Control, then press Enter ↵  (see 9.1 - 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 ↵ .

• From the Setup System Menu, shown at right, use the arrows

↑ ↓

 to

 

choose Setup Input and press Enter ↵ .

• From the Select Input Menu, choose the input you want—for exam-

ple, Input_01—and press Enter ↵ .

Table 21 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 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 Universal Monitor responds to an alarm or event.

Use the steps following Table 21 to change the default settings for any digital input.
