Power Supply Status Indicator
The green power supply status indicator is located next to the lightbulb symbol and
indicates these power states.
•
ON = +5 and +24V DC current available from power supply
•
Off = No input power, power-fail enabled, or overvoltage
exceeded/protection enabled
Packaged Controller Status Indicators
The six packaged controller status indicators are located at the top left corner of the
CompactLogix packaged controller. Use this table as a reference when interpreting
all six of the packaged controller status indicators.
TIP
When power is first applied to the controller, the OK, NS, MS, and LNK
status indicators display a complex sequence of varying red and green
states. This sequence indicates the power-up self test and takes
approximately 1…2 minutes for the packaged controller to complete.
