CHAPTER 8
Using the LEDs
(OIT3250, OIT4450, OIT5400 only)
The OIT3250, OIT4450 and OIT5400 have three types of LEDs: System, Status and
Function Key.
System LEDs
The four System LEDs provide the OIT operator with feedback on certain OIT events:
Message LED
The Message LED only operates when the screen stack is enabled in stacked mode. In
stacked mode, the Message LED blinks whenever there is a screen waiting to be
displayed. It continues to blink until the screen stack contains only historical screens. For
more information on the screen stack, refer to the Screen Stack section in CHAPTER 5:
Displaying Stored Screens.
Alarm LED
The Alarm LED blinks when an alarm occurs. It continues to blink until the OIT operator
acknowledges the alarm by pressing the ALARM ACKNOWLEDGE key. For more
information on alarms, refer to the Alarm Screens section in CHAPTER 3: Stored Screens.
Run LED
The Run LED blinks once every five seconds as long as power is applied to the OIT.
