remotely monitored units. Green “POWER” and red “FAULT” LED’s on the power
modules, along with the Form-C alarm contacts on the back panel indicate the
core status of power system, even on non-ICM equipped units.
There is an option on the Setup page in the GUI for most alarms to make a
selection to have the system send an Email to designated addresses for remote
notification.
All alarms and warnings will be displayed on the ICM front graphic display, and
entered in the Alarm History log. (Most recent 20 alarms listed)
Alarms generally reset automatically when the trigger condition is removed.
Major alarms such as a Module DC Output Failure or Module Configuration Error
require that the module be temporarily removed to cycle input power and clear
the fault.
