Theory of SC Production Operations

Containers transition from the production line to the SC conveyor for leak testing will be monitored and controlled by
various photo eyes, hold and reject cylinders.
Containers not sensed by the photo-eye will not be tested and will be allowed to pass through the machine
Test Photo-Eye (PE)
The test photo-eye is used for probe positioning on the container for the leak test. This eye must be adjusted properly
for accurate test probe placement. For proper setup of the Test PE please refer to the Advanced Operator Manual.

Downstream Pause Photo-Eye (photo not shown)
The downstream Pause PE is used to prevent downstream line stoppages from backing up into the testing area. The
downstream photo-eye should be set a minimum of 10-15 containers downstream of test head. Whenever this eye is
blocked by containers, the SC will stop processing containers by extending the hold cylinder and posting a message
on the display that the machine is waiting for the downstream photo-eye. When the photo-eye clears, container flow
will resume.

Detects that a defective container has been ejected.
Detects container presence for testing.
Upon test completion the test probe will retract. If the container is
PASSES the container will advance down the line. If the container
FAILS a reject cylinder will knock it off the line. The reject
verification sensor confirms that a container that FAILS is rejected.
Failure to detect the FAILED container will result in an alarm and
machine stoppage.
