To prevent this, use the latest firmware, and double check your FOV (over voltage fault) setting in Granity. |
To check if the regenerative circuitry is damaged, a multimeter (resistance meter) is needed. | To check if the regenerative circuitry is damaged, a multimeter (resistance meter) is needed. | ||

The measured resistance should be close to 2.2 Ohm in single resistor SimuCUBE boards, and close to 2.35 Ohm in boards where two resistors are soldered. | # Measure the resistance from the X2 pad HV+ to RES.

+ | Please note, that some multimeters do not compensate for the test wire resistance, and this might lead to higher value when measuring the resistor. | ||
Should the resistor measure more than 5 Ohm, and/or the MOSFET measures less than 10 kOhm, then double check your measurement, and if the results persist, then the respective component need to be changed. | Should the resistor measure more than 5 Ohm, and/or the MOSFET measures less than 10 kOhm, then double check your measurement, and if the results persist, then the respective component need to be changed. | ||

It is possible, but very rare, that SimuCUBE gets stuck in DFU mode or switches to DFU mode by itself without user interaction. | It is possible, but very rare, that SimuCUBE gets stuck in DFU mode or switches to DFU mode by itself without user interaction. | ||
