Screen Identification
The feed station has indicated that it requires attention. This indicates that it may no longer be able to supply material
to the metering unit. Refer to the feed station manual and check if there is sufficient material in it.
These warnings indicate that the combination of the shot size and the injection percent will result in inconsistent mix-
ture in the material. This can be fixed by decreasing the shot size of the injector. This will cause it to inject material
more often.
The color injector is designed to dispense the entire contents in about 0.2 seconds. This depends on the air pressure
supplied to the color injector. The refill time is approximately the same as the dispense time. It also relies upon the air
pressure supplied to the unit. The message will be generated when a shot size is too small. Refer to Adjust the Col-
orant Injector Shot Size, page 38.
