CRUZcontrol Logic Assemblies are designed to be fail-safe. A loss of module
power, a disconnected or severed cable, or a dirty or failed photoelectric
sensor will all result in the stopping of a zone, initiating accumulation beginning
from the affected zone.
•
In Progressive Logic mode, failure of a Logic Assembly to function properly
could possibly result in product accumulating with zones not stopping as
required. While this should be unlikely due to the fail-safe nature of the Logic
Assembly, a product jam preventing product from blocking a zone sensor
would also result in a zone not functioning. The effects of such a failure should
be considered. This type of failure could result in excessive line pressure,
eventually causing product to push through the discharge zone of the
conveyor. If needed, jam detection sensors should be used to minimize the
effects of such a failure.
•
Conveyors should not be operated with 100% of the logic modules switched to
the progressive mode in the contact accumulation mode. This could cause line
pressure issues if there is a jam since in the release mode, progressive ignores
the photo sensors and dumps all the zones at once, in the same way slug
discharge operates.
In the progressive release mode for contact accumulation,
it is extremely important to set every 5th logic module to basic. Do not set all
logic modules to progressive unless your line is under 20’ long.
This limits a
product jam condition line pressure to 16’ of conveyor. Failure to set every fifth
logic module to basic can result in extreme line pressures that can damage
your conveyor, product and could cause injury.
•
CRUZcontrol provides the ability to slug release. If the line is set to Slug
Release, all affected zones will run immediately, regardless of downstream
conditions, resulting in the immediate release of product with little or no gaps.
Both the Basic and Progressive Logic modes will release at the maximum
possible discharge rate when slug release is enabled. Slug release does
create a situation where a product jam will result in excessive line pressure
buildup. If the slug release feature is used, it should be used with caution, and
for a limited number of successive accumulation zones.
•
The “Air to Brake” operation requires a consistent supply of air to operate
safely and predictably. The system air supply should be monitored to insure
that adequate air pressure is available before operating conveyors.
