5.4.6 COLOR

Although the color feeder is not considered a pozzolan
metering system in the Commander computer it does
function in the same way as the cement and AUX1 metering
systems.

The diagnostics steps are the same as the primary cement
metering system.

The color feeder also typically runs at much lower speed
ratio then the cement, so also be careful of low (<10RPM)
setpoints. If the speed setpoint is low, increase your belt
speed as high as you can. This will increase the color
speed setpoint at the same time.

The Commander control system will warn the mix design
creator / operator when the speed ratio goes below 15% by
changing the text to red.
