Operation
The Product Present Photosensor is connected to a PLC (programmable logic controller). The
Photosensor is used to sense if product is accumulated behind the Product Stop, ready to be
released. The Photosensor is also used to sense a gap in the flow of product adequate enough to
raise the Product Stop after releasing product from the lane.
The Product Stop is solenoid activated, and controlled by the PLC. The stop is lowered by energizing
the solenoid.
Function Module #1
(a Release Function Module) is configured and wired for Singulation Release
operation. (Refer Table 4). The signal provided to the Product Stop solenoid is also connected to
Function Module #1.
When the Product Stop is raised (solenoid and Function Module not energized), product blocking the
Photosensor of the CRUZcontrol Logic Assembly will result in the conveyor zone going into
accumulation and the zone brake being activated. This in turn enables accumulation beginning with
the next upstream accumulation zone, once the Photosensor in that zone is blocked.
Function Module #2
(also a Release Function Module) is configured and wired for Logic Interrupt
operation (Refer to Table 4). When it receives a signal (from the PLC), it passes the logic signal from
the downstream accumulation zone to the upstream accumulation zone. Accumulation and release
function normally, as if there no Function Module installed.
To create a gap in the flow of product, the PLC signal to Function Module #2 is turned off. This puts
the zone upstream of Function Module #2 into accumulation mode, once its Photosensor is blocked.
The brake in the zone is also set whenever the zone is set to accumulate.
