Information about the Light Emitting Diode (LED) battery indicator system used on pre-2016 Dumpmaster models, which changes colour or starts flashing to indicate the battery state.
The battery state on Simpro machines produced prior to 2016 is indicated by a small Light Emitting Diode (LED) indicator on the control panel. This indicator uses electronics to measure a 30-second average voltage of the electrical system, and changes colour or starts flashing to indicate the battery state.
- When power is first turned on the LED will display green. If the voltage is high (above 12.3v) it will remain green. If the voltage is below 12.3v it will change quickly to red, and if below 11.7v to flashing red.
- To get an accurate battery status after turning the power on, the machine should not be used for 30 seconds as the LED indicator needs a steady average voltage. Using the machine will cause the voltage to drop temporarily, so the indicator will remain on red.
- Once the indicator is solid green, it will remain green unless the voltage drops below 12.3v for more than 30 seconds – it will then turn red. If the voltage drops below 11.7v for more than 30 seconds it will turn red flashing.
- Once the indicator is red flashing, it needs voltage above 12.7v for more than 30 seconds to return to red, and above 13.7v for more than 30 seconds to return to green.
- Once the indicator has turned red it usually will not return to green until the battery is charged.
| Voltage direction | LED State | Voltage value |

| Up | Green | 13.7 |
| Up | Red | 12.7 |
| Down | Red | 12.3 |
| Down | Red Flashing | 11.7 |
