4.1 INPUT CONTACT ISOLATOR BOARD
The Input Contact Isolator Board (ICI) provides a Liebert EXL module interface for up to eight external user
alarm or message inputs to be routed through the EXL’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 Option Settings under the Config menu on the HMI touchscreen display. The Input Contact
Isolator dialog box contains eight choices to match the eight channel input board. Each button can be labeled 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:
• Labeling the input contact assignments for the setup.
• Setting the delay for an external event triggering an alarm.
• Reviewing 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.
