Understanding LED Indications

tip

Looking for the meaning of the HMI/RFID LEDs? Check out the RFID/LED boards page.

1. Introduction

When you power on or reset a Bender Charge Controller, its front-facing Status LED(s) will indicate the current system state. Learning to read these indicators allows you to:

• confirm whether the device is booting or ready,
• diagnose issues early, and
• determine when you can safely access the Config UI.

This page summarizes LED patterns across three controller types (CC613, CC612, ICC1324) and distinguishes regular vs. Eichrecht firmware behavior.

---

CC613

Regular

The status LED is located on the front of the controller.

Behavior	Meaning
(static) ORANGE	Power on, System booting
(static) BLUE	Embedded Linux is starting
(static) GREEN	Firmware starting
(blinking) GREEN	System running, system ready for operation
(blinking) RED	System error

Eichrecht

Behavior	Meaning
(static) ORANGE	Power on, System booting
(static) BLUE	Embedded Linux is starting
(static) GREEN	Firmware starting
(blinking every 10s) GREEN	System running, system ready for operation
(static and blinking every 10s) BLUE	Vehicle is charging
no LED showing for 10 seconds	Signature is generated
(blinking fast) RED	System error
(blinking) RED	Signing at the end of charging (ca. 39 seconds)

Ethernet indications

Behavior	Meaning
Off	No Ethernet connection
(static) GREEN	Ethernet connection
(blinking) YELLOW	Data exchange at 100 Mbit/s
(static) YELLOW	Data exchange at 10 Mbit/s

CC612

Regular

The CC612 has three LEDs (Alarm, Ready, PLC) that are to be found on the controller.

Behavior	Meaning
(static) ORANGE GREEN GREEN	Firmware starting
(blinking) GREEN	System running, system ready for operation
(static) RED	System error

Eichrecht

Behavior	Meaning
(static) ORANGE	Power on, System booting
(static) BLUE	Embedded Linux is starting
(static) GREEN	Firmware starting
(blinking every 10s) GREEN	System running, system ready for operation
(static and blinking every 10s) GREEN	Vehicle is charging
no LED showing for 10 seconds	Signature is generated
(blinking fast) RED	System error

Ethernet indications

The CC612 does not have an integrated Ethernet Port. The Ethernet activity is indicated by the USB adapter.

ICC1324

Regular

Behavior	Meaning
BLUE continuously	Embedded Linux is starting
GREEN continuously	Firmware starting
GREEN blinking	System running, system ready for operation

Ethernet Indications

Behavior	Meaning
Off	No Ethernet connection
GREEN blinking	Data Exchange at 100 Mbit/s
GREEN not showing	Data Exchange at 10 Mbit/s
YELLOW continuously	Ethernet Connection
