A simple solution for accumulation release control is to add a CRUZcontrol Discharge Logic Assembly
(DLA) just downstream of the last NBA®23 Logic Assembly. A Discharge Logic Assembly is a Basic
Logic Assembly without a solenoid valve attached. Since there is no solenoid valve, the DLA will work
for either NBA 23 or XenoROL® applications.
The following hardware listing is for two DLA kits consisting of the Discharge Logic Assembly, a reflector,
and mounting brackets. The mounting brackets provide for mounting of the DLA and reflector either ½
inch or 3 inches above a standard XenoROL side channel. Since every application is different, there will
usually be a need to drill mounting holes for the brackets.

The mounting location of the photoelectric sensor and the reflector will determine release performance.
A good starting point would be to locate the photoelectric sensor 12 inches downstream from the charge
end of the induction conveyor, and the reflector 18 inches downstream from the charge end. The final
locations should be determined based on system performance.
The Discharge Logic Assembly is connected to the Logic Assembly at the discharge end of the NBA 23.
There is no need for a Function Module to be attached to it. The DLA does not need to be given a release
signal. Product blocking that photoelectric sensor will stop release from the NBA 23 discharge zone,
until the photoelectric sensor clears again. This operation is left enabled and ready to function regardless
of whether the induction conveyor is running or off. There is no need to interface the CRUZcontrol
operation with the induction conveyor operation, since the functioning of it is based solely on product
movement.
Example 7:
Power Monitoring.
There could be situations where it is desirable to monitor the 24 VDC power source for the CRUZcontrol.
A loss of power, for whatever reason, will result in all zones going into accumulation, immediately stopping
all product movement. This would be a problem if the accumulation conveyor were fed by a section of
non-accumulating conveyor, such a belt conveyor.
The 115 VAC Input Power Supply (TGW Systems part number 1101825) is provided with a power monitor
contact which is closed whenever 24 VDC output power is available. If using other power supplies, the
24 VDC power could be monitored directly by being connected into a 24 VDC PLC input, for example.
Another approach is to power a 24 VDC relay, and use the relays’ contact as an indication of power on.
