1. Onboard RGB Status LEDs

The ICC1624, ICC1324, and ICC1314 controllers feature 4 onboard RGB status LEDs that indicate the current state of the charging station.

Situation	LED pattern	Speed	Meaning
# Ready (no vehicle)	Blue solid	Steady	System ready, no vehicle connected
# Ready (vehicle connected, State B/C)	Blue blinking	Slow	System ready, vehicle connected
# Reserved by backend (no vehicle)	Blue blinking	Fast	Reserved for another user, no vehicle
# Reserved by backend (vehicle connected)	Blue blinking	Fast	Reserved for another user, vehicle connected
# Waiting for authorization	White solid	Steady	Waiting for user authorization
# Authorized (no vehicle)	Blue blinking	Slow	Authorized, waiting for vehicle
# Charging (vehicle State C)	Green solid	Steady	Active charging
# Charging (vehicle State B2)	Green pulsing	Pulsing	Charging suspended by vehicle
# Paused / Suspended	Green blinking	Slow	Charging paused or suspended
# Unavailable	Red solid	Steady	System unavailable
# Unavailable (vehicle State D1/D2)	Red blinking	Slow	System unavailable, vehicle in error state
# Permanent error	Red solid	Steady	Permanent system error

Error	LED pattern	Speed	Meaning
# Residual current detected (RCD/RCMB)	Red blinking	Slow	Residual current protection triggered
# Vehicle State E	Red blinking	Slow	Vehicle error state detected
# Diode check failed	Red blinking	Slow	CP diode check failure
# Locking failed	Red blinking	Slow	Cable lock mechanism failure
# Temperature sensor unreachable	Red solid	Steady	Temperature monitoring failure
# Relay input triggered	Red blinking	Slow	External relay input activated
# Contactor welded	Red solid	Steady	Contactor welding detected
# Meter unreachable	Red solid	Steady	Energy meter communication failure
# Overtemperature	Green blinking	Slow	Temperature limit exceeded
# Overtemperature warning	Green blinking	Slow	Temperature warning threshold reached
# Wrong charging cable	Red blinking	Slow	Incompatible or faulty cable detected
# Overload stage 2	Red solid	Steady	Current overload protection triggered
# Wrong phase installation	Red blinking	Slow	Phase configuration error
# State D	Red blinking	Slow	Vehicle State D detected
# Voltage too low/high	Red blinking	Slow	Supply voltage out of range
# Meter OCPP error	Red blinking	Slow	Energy meter OCPP communication error
# Backend disconnected (if configured as error)	Red flash	Flashing	Backend connection lost

Pattern	Visual behavior	Timing	Notes
# Blinking slow	LED switches between ON and OFF at a steady rate.	500 ms ON / 500 ms OFF (1 Hz)	Individual blinks are easy to distinguish.
# Blinking fast	LED switches between ON and OFF at a higher rate.	125 ms ON / 125 ms OFF (4 Hz)	Often perceived as rapid flicker.
# Flash	LED turns ON briefly, then remains OFF for the rest of the period.	125 ms ON / 875 ms OFF (1 Hz)	Short pulse with a long pause.
# Pulsing	LED smoothly increases and decreases brightness in a repeating cycle.	4 s brightness cycle	“Breathing” effect.

The ICC controllers have integrated Ethernet ports with status LEDs.

Situation	LED pattern	Speed	Meaning
# No connection	Off	–	No Ethernet connection
# Connected	Green solid	Steady	Ethernet connection active
# Data transfer	Yellow blinking	Blinking	Network data transmission
