18.7. Battery Setup: Digital Input (BDS)
String View > Setup|Battery|Digital Input
The Digital Input dialog box is available only when connected to String 1 of the BDS-256
controller, as defined on Setup|System|String. The BDS has 16 digital inputs that may be
connected to external dry contacts. You may set up these inputs to report an alarm when the
external contacts are activated. An alarm can also activate the critical or maintenance relay on
the BDS. Not available for BDS-40.
Figure 70. Battery Setup - Digital Input (BDS-256)
Input Name - Assign a name to the input connected to the external contacts and indicate if
the contacts are normally open or normally closed. To disable an input, clear the input name.
N/C or N/O - Select the N/C box if the external contacts are normally closed. Select the N/O
box if the external contacts are normally open.
Report - Selecting this check box lets the monitor report a digital input alarm. When not
selected, reporting is disabled for that input.
Critical and Maintenance - Two alarm contacts are available. Select Critical or Maintenance
to define which contacts energize upon digital input alarm. If neither is selected, the Report
check box clears and alarm reporting is disabled for that input. These settings do not affect
the bar graph colors.
