Containers are rejected erratically

Note
8-34

Time Delay is incorrectly set

1. Pass reject test container through the inspector and observe the
time delay synchronization. The rejector pad's centerline
should contact the container's centerline at the point of impact.
2. If not, adjust the reject timing settings in the inspection unit.

Rejector is not in the correct position

1. Verify the rejector pad, when completely retracted, is 1/8 inch
from the containers as they move down the conveyor line.
2. If not adjust the Stroke Offset function.

Rejector Pad fatigue or failure

1. Fatigued or worn pads cause the rejected container's trajectory
to change.
2. Replace rejector pad.

Facility air pressure drops or is erratic

1. The facility air supply pressure must be maintained at ≥10 psi
over the regulator pressure setting of 65 psi.
2. If facility air supply pressure drops when rejector operation is
erratic, install an accumulator upstream of the rejector air
controls.

Rejector sticking or binding

1. Check the rejector piston for smooth movement.
2. If it is binding, you must replace the Servo unit. See your
Servotec Manual for parts information.
If intermittent or erratic rejector operation continues, contact
Industrial Dynamics Customer Service for assistance.
