Fatal Error Codes

When the RX3i CEP encounters a fatal error, it blinks an error code pattern on the OK LED
with an Amber color. In this mode all other LEDs except PWR LEDs flash Amber once to
indicate the start of the error code. Next the OK LED blinks a 2-digit decimal error code. The
LED first blinks to indicate the most significant error digit, then after a brief pause blinks
again to indicate the least significant error digit. After another brief pause, all LEDs flash
Amber again and the error code pattern repeats. Repetitions continue indefinitely until the
Carrier is power cycled.

Carrier Identification

The LEDs on an RX3i CEP Carrier can be commanded to repeatedly turn ON and OFF in a
special sequence, to help locate or identify the CEP Carrier:
•
•
The Carrier Identification LED Pattern is initiated by the PROFINET DCP Identify Device
command. Carrier identification can be initiated using the PAC Machine Edition Discovery
Tool by refreshing the device list, double clicking on the RX3i CEP, and clicking the Identify
Device button on the RX3i CEP properties pop-up window.
2.2.3

Firmware Update

While the RX3i CEP is in firmware update mode, the OK, CONN, PRT1 and PRT2 LEDs blink
Green for 1 second and then off for 1 second in unison. During firmware update operation,
all the PORT LEDs and the CONN LED blink in the firmware update
pattern since the ports are disabled, and all the PWR LEDs are off even the corresponding
power source is good.
2.2.4

Power-up LED Patterns

When power is applied to the RX3i CEP Carrier, it loads a firmware image. The PWR1 and/or
PWR2 LEDs are green and steadily ON. During the power-up/reset process, the CEP runs
diagnostics and initializes its hardware components.
After completing power-up sequence, the OK LED changes to green, steadily ON. If a fatal
error occurs during powerup, the LED blinks instead.
LED Operation & Connectors
First the green LEDs are turned on in the following order (from bottom to top): PRT2,
PRT1, CONN, OK. There is a short delay between turning on each LED.
The LEDs are then turned off in the reverse order (from top to bottom). There is a
short delay between turning off each LED.
