Controller self-test function: sub-dynamic self-test and self-test surge plates sx440 static production, as long as the power state controller, it will automatically detect the status of the interface associated Dongguan generator SX440, such as Shift, brake handle, or Other external switches, etc., in case of failure, the controller automatically implement protection, and fully guarantee the safety of riding, when troubleshooting protect the state controller will automatically resume. Anti-charging function: brakes, slow down or coasting downhill EABS energy generated is fed back to the battery, play a counter-charge effect, thereby maintaining the battery to extend battery life, increase continues the course. Controller repair method: When the electric car brush controller does not output a) set the multimeter hair +20 (DC) stalls SX440, the first measurement of the gate of the high and low potential output signal. 2) When the brake handle as pinch, there are more than 4V gate signals potential change SX440 factory in Dongguan, you can exclude the brake failure. 3) Then follow on foot brush Controllers Common Menu morals, values ??and the measured voltage logic chips public morals master circuit analysis, and check the value of each chip peripheral components (resistors, capacitors, diodes) whether and components identifying surface consistent. 4) Finally, check the peripheral device or integrated circuit fails, you can replace the same type of device to troubleshoot.
