23 Brake Control
When a discharge zone brake assembly is provided with NBA 23 conveyor, the brake control comes
already wired and plumbed from the factory. The following is provided to explain how it functions.
The two photoelectric sensors as shown are located in the discharge zone, sharing the same hole through
the conveyor side channel and aimed at the same reflector. In this way they will always simultaneously
sense the presence or lack of product. The Brake Logic Assembly is progressive logic, which passes
the run or accumulate status upstream to the next logic assembly, which in this situation is the same
zone. The Brake Logic Assembly is also XenoROL
®
, since an accumulated condition requires air to
activate the brake.
Auxiliary Photoelectric Sensors
There is often a need to sense product presence on a CRUZcontrol equipped conveyor, with the sensors
connected to a control system other than CRUZcontrol. To allow for this, adequate space has been
provided along side of the CRUZcontrol photoelectric sensors to allow for the mounting of a second
independent photoelectric sensor, sharing the same holes through the conveyor side channels and the
same reflector. Appropriate holes are provided for the photoelectric sensor mounting bracket. The
discharge end of NBA 23 conveyor is also provided with an additional mounting location for a
photoelectric sensor and reflector (straight across scanning, no offset).
