Loss-In-Weight Color Feeders Chapter 4: Operation 23
Feeder Operation (Manual Mode)
If the feeder is required to operate in manual mode (where it just runs a pre-programmed
output rate when operating), do the following:
1. Turn the Reload switch on the control box from the AUTO position to the MANUAL
position. (Doing so disconnects the power to the CPU board completely and diverts
the +24VDC to the Reload solenoid valve. This ensures that the solenoid valve stays
open permanently and material is present all the time into the additive feeder hopper.)
2. Now using the speed pot dial on the SCR drive for the auger, set the desired speed as
necessary to run the feeder in a strictly VOLUMETRIC mode.
3. Provide some manual method such as a speed shutdown or voltage shutdown circuit
to shut the feeder off (if mounted on an extruder so the unit does not feed color when
the screw is stopped).
Note: The feeder does not automatically follow the screw or shut down when
in the manual mode. It meters at a preset rate when operating.
