Poer expander

How does one avoid pulling too much current through the power expander? The Cortex analog value is Refer to the following LED status chart for more information.

The examples are for a bit result maximum value of That means that he has 5 motors on4 on the expander, and only ONE on the breaker. February 11,pm 19 Will a power expander fix my drive train problem.

To determine this value, divide the Power Expander read-out by the divisors shown below. He said he had powering his drive, and on his lift. The onboard LED provides its current status. Setup This is all great, but how do I set this up in real life? You said that he has motors on the different breakers, but that adds up to The power expander gives you a way to run up to 4 motors off of a dedicated second battery. This can be used to determine the approximate remaining voltage of the battery connected to it. Move to the slot on the other side of that letter, and plug in the appropriate motor.

First, a short extension wire runs from the numbered cortex slot to a lettered slot on the power expander. To determine this value, divide the Power Expander read-out by the divisors shown below.

When plugging motors directly into the Cortex, one wants to spread out the motors between ports and portssince each half of the motor ports is regulated by a separate 4-amp circuit breaker. What are those slots with letters on them for? This will restore normal LED response.

Provide power to the unit by connecting a 7. This can be used to determine the approximate remaining voltage of the battery connected to it. The main point is that it prevents you from daisy-chaining your batteries together, which would double your voltage and indeed be an unfair advantage and at the same time would risk damaging your components.

The various plugs need to be pretty thoroughly pushed in in order for the casing to slide. Suggested threshold values are: above is good 6. A little daisy chain will run from the cortex to the power expander to the motor. Assuming he is using more motors ports 1, 6, 7, and 10, then 6 and 7 are probably on the expander, too. This seems extremely uneven to me. Spreading out the motors—particularly motors that will run at the same time—reduces the likelihood that too much current will be drawn from either group tripping the circuit breaker. One bank has pins sticking out of it for a female plug and the other bank has holes for a male plug. What are those slots with letters on them for? The Power Expander enables the user to spread a VEX robot's motor load across two batteries, extending run time and increasing performance. If that lift is under heavy load or stress, then even more current is trying to be pulled through the power expander, increasing the likelihood that the circuit breaker will trip. This can be used to determine the approximate remaining voltage of the battery connected to it. On the power expander, the entire grey outside of the casing slides a teeny bit to cover up the edges of the plugs to keep them from being pulled out. That means that he has 5 motors on , 4 on the expander, and only ONE on the breaker.
