; Check to see that the additive pellets are feeding consistently out of the weigh
hopper and not bridging occasionally in the hopper discharge throat. Consult the
factory if this is the case. We do offer a larger opening hopper (up to 2
1 /
2
inches). The feeder is designed for virgin pellet color concentrate. IT IS NOT
DESIGNED FOR REGRIND MATERIALS.
; Check the extruder screw speed pick-up proximity switch to ensure that it is
reading the extruder screw revolutions accurately.

; Check motor speed. Unit is probably running too slow. Change gear reducer to
higher ratio unit.
; Check auger to housing clearance, and if pellets are binding auger, consult
factory. Check auger for straightness. Sometimes the operators will let the drive
hang off the auger without removing it fully from the housing. This will bend
the auger. Bent augers are not covered under warranty.
; Check input voltage and wiring size to see if a low voltage situation exists.
Quite often the feeder and 110V loading systems are wired into the same outlet.
The voltage will check out at 120V when there is no load. Check the voltage
when all the units are operating at the same time. It will sometimes drop 20
percent or more. This indicates that the wire size to the outlet is too small to
carry the load required. This condition will normally show up first on the
loading system motors.
; Check the extruder screw speed pick-up proximity switch to ensure that it is
reading the extruder screw revolutions accurately.
