Section D. ACS System Operations
A stroke that is too short or too long would result in improper position of the can when the seam cycle begins
which will result in a can crush. Check also that the can is centered.
D.9.1.3
Can does not feed onto seamer
Problem Symptoms
Can arrives in the load position (end of conveyor where push arm
#1 is) but the push arm does not activate to load the can onto the
seamer.
Solutions
Check that the CIP button is turned off
Check the proximity sensor that is mounted in the ‘end
stop’. It may need to be advanced in the block in order to
detect the can. Loosen set nut and turn the sensor so that
it advances in the block, then retighten the set nut.
Check the sensors on the front and back of push arm #1.
There is a sensor on each end of the cylinder and they each
have an LED light. When the sensor is at rest the back
sensor light should be illuminated. If it is not, the sensor
has been misaligned and it needs to be shifted forward or
backward on the cylinder body until the light stays
illuminated.

D.9.1.4
Push arm #1 does not retract
Problem Symptoms
Push arm loads a can on but then stays in the fully extended position – won’t retract.
Solutions
In manual mode, press the push arm #1 button and hold down. Check that the front sensor LED light (yellow) remains
illuminated until you take your hand off the button. If it is not illuminated, the sensor has to be shifted forward or backward
on the cylinder body until the light stays illuminated.
D.9.2
Lid Dispense Troubleshooting
D.9.2.1
Can lids drop through the end of the lid slide
Problem Symptoms
Lids frequently fall out of the slide before a can arrives.
Solutions
Check the position of the lower metal retaining bar – it may have popped out of the recessed groove in which it
should be positioned AND/OR the elastic tension may need to be increased
D.9.2.2
