SWITCH
Operation: All cartons stop at the Work Zone when the CRUZcontrol photoelectric sensor in that zone is
blocked. To release cartons stopped at the zone, the Foot Switch needs to be depressed until the carton
clears the photoelectric sensor.
Carton release will only occur if the next downstream zone sensor isn’t blocked. If the alternate wire
connection from the Foot Switch to the Function Module is made, (teVDC instead of the
downstream Logic line), carton release can occur regardless of the state of the next downstream zone
sensor.
Adding a selector switch with one normally open contact, wired in parallel with the footswitch, would allow
for selecting with or not to enable the work zone operation.
Example 5:
Progressive Logic accumulation release control.
The Progressive Logic CRUZcontrol Logic Assemblies provide for high throughput rates and efficient
release, compared to Basic Logic. In simple terms, Basic Logic tries to create zone length gaps in the
flow of product, where as Progressive Logic allows product to flow without creating gaps.
The product throughput rate for Progressive Logic, measured in case-feet per minute, can equal the
conveyor speed. This can create problems. If, for example, an NBA®23 conveyor running at 180 feet
per minute is feeding product to an induction belt conveyor running at 100 feet per minute, the belt
conveyor will be overrun, meaning that excessive line pressure will build up at the discharge end of the
NBA 23.
There are several possible solutions to handle this situation:
1. The speed of the accumulation conveyor could be set at less than the speed of the next
conveyor down-stream. In the example mentioned, if the NBA 23 were running at 100 feet per
minute, there wouldn’t be an issue. This is not often possible. If the accumulation conveyor
needed to receive product at a higher input rate, the speed would have to be higher. If densely
packed accumulation were desired, that would also require the speed to be above 100 feet per
minute.
