WCS-2 and WCS-4 Subracks and Modules
WCS Subrack Alarm Connector
The Alarm connector on the back panel of the WCS-4 and WCS-2 subracks has
•
four opto-isolated (chassis-ground referenced) dry contact inputs to monitor external devices
•
one Summary Alarm Relay that energizes when specific alarms are triggered—the thresholds of which
are shown in the preceding graphic. [
Which alarms? We need to match the Summary Alarms shown above with
the actual corresponding alarms.
