Progressive Logic Operation
Progressive accumulation functions such that no zones are set to accumulate unless ALL the
downstream electronic sensors are blocked, meaning that all downstream zones hold accumulated
product.
In the above example, the discharge zone, Zone 6, is shown stopped which is the result of the release
from the zone being inhibited (receiving conveyor is stopped) and the Zone 6 sensor being blocked.
Zone 5 sensor not being blocked results in all upstream zones, Zone 1 through Zone 5, running.
NOTE:
(Progressive Logic) Products being transported on accumulation conveyor can remain tightly packed,
without any gaps being created. The transportation throughput capacity of the conveyor is not
reduced due to zoned accumulation.
Discharge from Progressive Logic
When the discharge zone, Zone 6, is provided a release signal, all upstream zones also release.
There is no gap between released products; assuming conveyor speeds (accumulation conveyor and
downstream conveyor) are identical. The Progressive Logic discharge functions the same as a Slug
Release. Initiating the Slug Release will also result in all products releasing, regardless of zone
conditions.
In the progressive release mode for contact accumulation, it is extremely important
to set every 5th logic module to basic.
