6.4.3. Local Zone Accumulate

On a newly Auto-Configured linear conveyor without any intervention from external signals, items will not stop on any zones in the middle unless the next downstream zone is occupied.

To cause either the upstream or downstream zone on a to accumulate an item when it arrives in a zone, you energize the Local Zone Accumulate signal on Pin 3 of the Control Port for the zone.

!If you re-energize the Pin 3 signal while the item is in transit and still blocking the zone sensor, the item will stop and if left like this, the zone will eventually generate an Arrival Jam. You can modify the function of the Pin 3 operation by making it active only upon leading edge of the zone sensor
