The SERIES-B Tilt box mod will display one of a number of error messages if there is a problem, but these are often easily fixed.

No tank

If there is no tank connected to the device, pushing the power button will cause the LED screen to display the ‘NO TANK’ error message. This error can also be caused by dirty connectors/threads, or a problem with the fitted coil.

Low power

If the battery has a remaining voltage of less than 3.3v, the LED screen will display the ‘LOW POWER’ error message before shutting off. The onscreen battery indicator will show as empty from 3.4v.


If the SERIES-B Tilt 50W overheats, it will enter sleep mode and will display the ‘OVERHEAT’ error message. The device will lock itself and will be inoperable until it has cooled to a safe working temperature.

Over 15 secs

If the power button is pushed down for more than 15 seconds, the device will cut out and display the ’15 SEC’ error message.

Tank short

If the SERIES-B Tilt 50W detects a short in the attached atomiser, the device will show the ‘TANK SHORT’ error message. Shorts normally occur if there is a problem with the 510 connector of the tank, or fault with the coil build. Overtightening the attached tank can also return the ‘TANK SHORT’ error message.


If the remaining voltage in the fitted IMR 18650 battery is too low to safely fire the attached atomiser, the device will show the ‘PROTECTION’ error message. For example, if you’re using a 0.5Ω coil and there is 3.7v remaining in the cell, selecting a wattage of more than 27W will return the error message. As the device is used, the remaining charge in the battery will drop. The SERIES-B Tilt 50W will automatically compensate to allow high-wattage vaping, until it can no longer do so safely. At this point, the ‘PROTECTION’ error message will begin to appear. To avoid this issue, recharge your battery once the ‘PROTECTION’ error message begins to appear. The ‘PROTECTION’ error message may also appear when using a battery which isn’t high-drain, or is otherwise unsuitable for use with the SERIES-B Tilt 50W.
