When the battery gets critically low, the RED light will illuminate.
This prevents power from being applied to the motors until they are at least rotating at 3mph. The motor makes approximately The Roth motorboards “maximum” speed of 18mph translates to optical pulses per second. If low power is detected the red LED will blink, and power will be shut off completely.

This page was last modified on 23 Marchat If the speed of this motor is less than 3mph, no power will be provided to the motors. The current code cannot be read because the “Code Microchio bit has been set, but it is possible to erase the chip and program it with new code.
The speed is controlled linearly, and no attempt is made to maintain a given speed for a given throttle position. The motorboard has an automatic low power shut off. The controller monitors the speed of one microchp the motors the one with a optical wheel “chopper” attached to an elongated motor shaft.
When the battery is almost dead, the red light will blink and the buzzer on the mucrochip contoller PCB will beep on and off 1 second on, 4 seconds off until the battery reaches the low power shut off. 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.
Retrieved from ” http: When you turn the motorboard ON, the green light goes on then off, then the yellow light goes on then off then the red light goes on then microdhip and then the green light goes on solid. Then the operator pushes to go. Navigation menu Personal tools Create account Log in.

This saves significant amounts of battery power and prevents the motorboard from starting accidentally. One turn of the wheel is at best inches Since there are eight optical slots on the chopper per turn, this means optical pulses per turn of the wheel. Views Read View source View history.
