VersaMax PROFINET Scanner LEDs
Power Supply LEDs
Each Power Supply LED (PWR1 and PWR2) is ON solid green when a minimum level of power
is being supplied on the corresponding power supply connector on the front panel of the
PROFINET Scanner.
OK LED
The OK LED is solid green ON for normal operation and when the PNS is in Maintenance
Mode. The OK LED flashes or is OFF for all other module states. If there is a failure during
power-up, or a fatal error during normal operation and the scanner is not configured for
automatic restart, the OK LED blinks amber in a failure pattern specific to the error.
