LED Status Indicators


RaptorLinx-Ai-ST status is indicated by several LED’s. All LED’s with the exception of the Ethernet Link and Activity LEDs are multi-colored and context sensitive. The following sections indicate the various meanings of all LED indicators.


Indicator Item LED State Description
M8 Sensors & OFF Both Pin 4 and Pin 2 Inputs are OFF and Pin 2 if Output is OFF
Solid GREEN Pin 4 Input is energized
Solid RED Pin 2 is energized (when Pin 2 configured as an Input)
Solid AMBER Both Pin 4 and Pin 2 are energized (when Pin 2 is configured as Input)
Flashing AMBER RaptorLinx is in reset to default mode
Blinking RED Pin 2 Output is energized and is PNP configured
Flashing RED Pin 2 Output is energized and is NPN configured
Module Status Blinking RED Module is starting task processes OR PLC has been disconnected

Digital Inputs
OFF Input not energized
Solid GREEN Input is energized
Flashing AMBER RaptorLinx is in reset to default mode
Motor Running OFF Motor is stopped or Motor is running below minimum RPM
Solid GREEN Motor is running at or above default minimum RPM

Motor Error & Status with Priority

Because multiple errors and/or status can exist simultaneously, each LED state for these indicators has a priority. If a LED state is with a higher priority value, it will take control of the LED. If two states are with the same priority value, the state that occurred the most recently will be indicated by the LED
