Please unplug unit and ensure outlet intended for use is earth grounded before attempting to use JuiceBox.Ģ-Beep Tones: Ground Fault Interrupt Startup Self-Test Failure Occurrence of this error state indicates that the unit is not connected to an earth grounded outlet. The tone pattern typically repeats so you can identify it. The sequence is a "Tii-duu" (High-Low) dual tone (intended to mean "Uh-oh!"), followed by a number of "Tii" (high) beeps to indicate which error is signaled. Buzzer tone sequences for error states are listed below. In the event of a system error, the JuiceBox unit will produce an audible sequence of tones to indicate its error state. *Information applies to JuiceBoxes built prior to August 28th 2015 (Rare) Early Buzzer codes (July-September 2015) : Check that your control pilot (CP) signal pin isn't shorted. This error is an internal system fault - usually related to pilot signal generation. If error persists after unplugging and rebooting the JuiceBox, and your car will not charge, please contact support. The relay should have closed for charging. This error code indicated that the relay is stuck open. The JuiceBox will automatically resume when it cools off. Move your JuiceBox to a cooler area, out of direct sunlight, or remove heating sources from area. The JuiceBox is too hot (over 80C internally). This error code indicated that your JuiceBox is overheating. The GFI trip is likely either caused by a wiring problem in the car or J1772 charging handle, or by significant line noise. If you continue to have this issue please contact support for further instructions. After 4 GFI trip events and automatic resets, the unit will not self-reset, and will continue to produce the 3 buzz tones every 3 seconds until the car is unplugged. The unit will remain inoperable for 15 minutes, during which time the unit will continue to produce the 3 buzz error tone every 15 seconds, and will self-reset after 15 minutes. This error code happens after a Ground Fault Interrupter ( GFI) trip event. If JuiceBox continues to signal this error, contact support. This error code Indicates unintended closure of relay in non-charging state. Unplug unit from wall outlet to prevent unsafe charger state. If it occurs intermittently or continues to occur, contact support. If this error persists unplug and reboot the JuiceBox. This error code Indicates possible failure of Ground Fault Interrupter ( GFI) circuitry. If the error persists unplug and reboot the JuiceBox. When using a 240V Line-to-Neutral, single phase mains supply, the Line and Neutral connections should not be reversed on L1 (H) and L2 (H2/N). If this is the case, please reverse them at the panel. The Ground connection is usually connected to Neutral at the circuit panel. On 240v single split-phase AC power (US standard), you should find approximately 120V between each line and the ground terminal of your outlet. Check that your circuit ground connection is established. Previous Generation (built Aug 2015 to Feb 2017) Switch off the circuit breaker connected to your JuiceBox. This error code indicates that the relay is stuck closed. Relay Stuck Closed (Disconnect immediately. Unplug from car in order to reset the GFI trip count to 0. If issue persists, contact Support. (Or plugged into something that’s not an EV). If issue persists, please contact Support.Ĭar not obeying J1772. While unit is unplugged, please also power circuit breaker off and on. GFI AutoTest Failure (JuiceBox system self-check failure) or Relay Stuck Open If issue persists, please contact Support. JuiceBox Error Codes Current generation (built from Feb 2017 to present)Ĭheck line and neutral connections as they may be reversed in the adapter or outlet.
