3.5 Fault Indication

When the fault indicator illuminates red, WattStation is indicating a fault.

WattStation faults will be either self-correcting or non-correcting.

• Self-correcting

: When the fault icon and LED ring around the coupler are

illuminated, the system is experiencing a self-correcting fault. In this state the

system will reset after 15 minutes, or a manual reset can be performed. Simply

remove and replace the connector to the EV, or power cycle the unit by holding

down the power button until the system turns off and pressing the power button

again to restart.

• Non-correcting

: When fault icon is illuminated and LED ring is not illuminated a

fault has occurred which requires a manual reset. Simply remove and replace the

connector to the EV, or power cycle the unit by holding down the power button

until the system turns off and pressing the power button again to restart.

If a fault condition persists have your local certified electrician inspect the system.
