Kelly KDZ Series/PM/Sep-Ex Motor Controller User’s Manual V 3.318Table 1: LED CODESLED Code Explanation SolutionGreenOffNo power orswitched off1. Check if all wires are correct.2. Check fuse and power supply.GreenOnNormal operation That’s great! You got solution!1,2 ¤ ¤¤ Over voltage error 1. Battery voltage is too high for the controller.Check battery volts and configuration.2. Regeneration over-voltage. Controller will havecut back or stopped regen.3. This only accurate to ± 2% upon Overvoltagesetting.1,3 ¤ ¤¤¤ Low voltage error 1. The controller will clear after 5 seconds if batteryvolts returns to normal.2. Check battery volts & recharge if required.1,4 ¤ ¤¤¤¤ Over temperaturewarning1. Controller case temperature is above 90℃.Current will be limited. Reduce controllerloading or switch Off until controller cools down.2. Clean or improve heatsink or fan.2,2 ¤¤ ¤¤ Internal volts fault 1. Measure that B+ & PWR are correct whenmeasured to B- or RTN.2. There may be excessive load on the +5V supplycaused by too low a value of Regen or throttlepotentiometers or incorrect wiring.3. Controller is damaged. Contact Kelly about awarranty repair.2,3 ¤¤ ¤¤¤ Over temperature The controller temperature has exceeded 100 ℃ .The controller will be stopped but will restart whentemperature falls below 80℃.2,4 ¤¤ ¤¤¤¤ Throttle error atpower up1. The throttle got effective signal at key-on. Cyclethrottle can remove the error. You mayreconfigure throttle effective range or foot switch2. The acceleration throttle must be turned fromzero up to high when the brake is released.Otherwise the controller will report this fault.3,1 ¤¤¤ ¤ Frequent reset May be caused by over-voltage, bad motorintermittent earthing problem, bad wiring, etc.3,2 ¤¤¤ ¤¤ Internal reset May be caused by some transient fault condition likea temporary over-current, momentarily high or lowbattery voltage. This can happen during normaloperation.3,3 ¤¤¤ ¤¤¤ Wrong connectionof throttleValid throttle signal is between 1V-4V. Fault reportbecause signal is less than 0.5V or greater than
