Liebert Universal Monitor 用户手册

Each input has a default label (Input_01, Input_02, etc.) that you may 

change to a more descriptive name for ease in recognizing alarms and 

events associated with the input. The label may consist of up to eight 

characters (see Table 20 for valid characters).

• From the Setup Input Menu, choose Label for the selected 

input—Label: Input_01 in the example at right—and press 

Enter ↵ .

• To change the input’s label, which may consist of up to eight char-

acters:

• Use the arrows

↑ ↓

 to

 

choose a character.

• Press Enter ↵  to advance to the next character position.
• When finished, press Enter ↵  again.

Each input may be set up as Normally Open (NO) or Normally Closed 

(NC). The default setting for all input points is NO (Normally Open).
If you require an input to be a supervised point, define the input as 

Normally Closed (NC).

• From the Setup Input Menu, choose Norm Open/Close, as shown 

at right, and press Enter ↵ .

• To change the normal state for this input, use the arrows

↑ ↓

 to

 

choose NO (Normally Open) or NC (Normally Closed), then press 

Enter ↵ .

Each digital input may be defined as Alarmable (AL) or as an 

Event (EV).

• For a digital input defined as alarmable, the following alarm reac-

tions occur when the status of the monitored input device changes: 

the LCD flashes, the audible horn sounds, configured pager num-

bers will be notified and a record is entered in the Alarm Log.

• For a digital input defined as an event, the status change is 

recorded in the Event Log.

By default, all digital inputs are set up as AL (Alarmable).

• From the Setup Input Menu, choose Alarm/Event, as shown at 

right, and press Enter ↵ .

• To change the type of digital input, use the arrows

↑ ↓

 to

 

choose 

AL (Alarmable) or EV (Event), then press Enter ↵ .
