CONFIGURATION SETUP (cont’d)
(APPLICATOR OPTIONS)
Crossover
– The Crossover Option allows for “zero downtime” operation by interconnecting two (2)
Applicators. Both Applicators are placed on the conveyor system one (1) upstream of the other. The
upstream Applicator is the “Primary” labeler while the downstream applicator is the “Secondary” labeler.
The Crossover routine has changed after 360a-2c.0.031 program version. In the new Crossover routine, the
Secondary still functions the same in that when it gets a signal from the Primary to turn on or off, it will
track the On or Off Distance and change active state. The Primary now will wait for the next Product
Detect signal after it stopped labeling to start the Changeover Sequence. The same is true of the
Secondary. If the conditions are set for a “transfer to the primary”, it will wait for an apply cycle before
signaling the Primary to start. This will insure the transitions occur in the same place every time. Also
changed is the Secondary will start labeling if the Primary goes into a Critical Fault or goes offline and will
continue labeling, even if the Primary is brought back online.
Primary To Secondary Example
With the Primary labeling and the Secondary ready to label, if the operator either takes the Primary offline
or it goes into a Critical Alarm, the Primary will stop labeling and waits for the next Product Detect Signal.
When the Product Detect Input turns on, the Primary sends a signal to the Secondary to start the “transfer
sequence.” When the product has traveled the “On Distance”, the Secondary will start labeling. The
operator can now correct the problem with the Primary and bring it back online.
Secondary To Primary Example
If the Secondary is labeling when the Primary is brought online, the Primary will not automatically start
labeling. In the new sequence, the Secondary continues labeling until it is taken offline, Critical or Low
Label Alarm occurs, or the “Transfer” Key is pressed. Taking the Secondary offline or a Critical Alarm
will cause products not to be labeled but if a Low Label Alarm occurs or the Transfer Key is pressed, the
Secondary sends a signal to the Primary to start labeling while it continues to label. The signal occurs at
the first apply cycle of the Secondary after the transfer is initiated. The Primary will then look for the next
Product Detect Signal to start labeling again. When it gets the signal, the primary sends a signal to the
Secondary to start the “Off Sequence.” Doing this gives the Secondary a consistent starting point for either
transition sequence.
Main Menu Changes
When the Crossover Option is on, the left side of the Main Menu will change. Depending whether it is
setup as the Primary or the Secondary, it will look similar to the screens below.
The Primary has two lamps that show which
Applicator is labeling. The reason is if the line
stops and both Applicators were online,
without this new setup, it would be impossible
to know which was the active Applicator.
