If the speed of this motor is less than 3mph, no power will be provided to the motors. This page was last modified on 23 Marchat This saves significant amounts of battery power and prevents the motorboard from starting accidentally. When the battery is almost dead, the mucrochip light will blink and the buzzer on the motor contoller PCB will beep on and off 1 second on, 4 seconds off until the battery reaches the low power shut off.

Views Read View source View history. When you turn the motorboard Microchil, the green light goes on then off, then the yellow light goes on then off then the red light goes on then off and then the green light goes on solid.

The motorboard has an automatic low power shut off. Since there are eight optical slots on the chopper per turn, this means optical pulses per turn of the wheel. If low power is detected the red LED will blink, and power will be shut microhip completely.

The speed is controlled linearly, and no attempt is made to maintain a given speed for a given throttle position. One turn of the wheel is at best inches Privacy policy About Motorboards Disclaimers Mobile view. The controller monitors the speed of one of the motors the one with a optical wheel “chopper” attached to an elongated motor shaft. When the battery gets critically low, the RED light will illuminate.

The motor makes approximately Retrieved from ” http: Because there is no indication that the motor is moving less than 3mph, if the optical wheel fails for any reason the motorboard will assume that 3mph has not yet been reached. This prevents microchi; from being applied to the motors until they are at least rotating at 3mph.


Then the operator pushes to go. Navigation menu Personal tools Create account Log in.

The motorboard will not function and there will be no indication as to the cause of failure. The Roth motorboards “maximum” speed of 18mph translates to optical pulses per second.

Actually it operates at Hz measured. The current code cannot be read because the “Code Protect” bit has been set, but it is possible to microochip the chip and program it with new code.
