3.2.3 Input Contact Isolator Board
The Input Contact Isolator Board (ICI) provides a Liebert
®
NXL
™
module interface for up to eight
external user alarm or message inputs to be routed through the Liebert
®
NXL’s alarm network.
The eight contacts are normally open dry contacts. When a contact closes, an event is triggered.
The Input Contact Isolator options are configured through the Input Contact Isolator dialog box,
which is accessed from the Internal Option Settings under Config dialog box on the HMI
touchscreen display. The Input Contact Isolator dialog box contains eight choices to match the
eight channel input board. You can label each button to identify the event associated with the
contact. When the dialog box is accessed, each button flashes to display the Input Contact
Isolator number and the user entered label. This label also appears in the Display Panel when an
event related to an Input Isolator Connector is triggered.
The Input Contact Isolator dialog box allows you to:
•
Label the input contact assignments for your setup.
•
Set the delay for an external event triggering an alarm.
•
Review the isolator contact assignments, once the labels are entered.
The delay allows setting the number of seconds that a condition must exist before it will trigger
an alarm. To configure the Input Contact Isolator relays:
1.
Press Internal Option Settings from the Config menu.
2.
Press which Input Contact Isolator is to be configured. The Input Contact Isolator dialog box is displayed.
