CROSSOVER SETUP

CROSSOVER MONITORING

If the applicator is a secondary labeler, the crossover sub-menu will have a MONITOR SECONDARY

SETUP selection. This menu is provided to aid the operator in setting up the crossover network and is

particularly helpful if the secondary applicator is not labeling or is double labeling products. If this is

selected, a screen will show the status of the following items:

• PRODUCTS BETWEEN HEADS: xx

• PRODUCTS BEFORE LABEL: xx

• SECONDARY INHIBIT INPUT: ON/OFF

The products between heads value indicates how many products are between the primary and secondary

applicators while the products before label value indicates how many of these products are already labeled.

The secondary inhibit status indicates whether the secondary labeler is enabled or not. If the inhibit input

is ON, the secondary applicator is not labeling. If the inhibit input is OFF, the secondary applicator is

labeling.

CROSSOVER PRECAUTIONS !

The crossover option insures that all products on a conveyor system are labeled by providing a redundant

system that will be activated if the primary applicator encounters an alarm. The following precautions

should be observed for reliable operation of the crossover network:

• Both the primary and secondary applicators should be of the same type and have identical setups

including the label sensors which should be set to detect the same edge on the label.

• Make sure the product detect sensors are properly configured so that multiple product detect

signals are not sent to the applicators. Multiple product detects will cause the crossover counters

to be wrong. When setting-up the system, it is a good idea to monitor the “Products Between

Heads” counter. When there are no products between the heads, this counter should be zero. If at

any instance of time the “Products Between Heads” counter doesn’t match what the operator

physically counts between the applicators, multiple product detects are being generated.

• Make sure that both applicators are brought online before the primary applicator labels the first

product. Going online synchronizes the two applicators.

• Do not take products off the conveyor system that are between the heads. This will cause the

crossover counters to be wrong.

• When the primary applicator enters into an alarm condition, allow the secondary applicator to

begin labeling before bringing the primary applicator back online. Failure to observe this

precaution will result in double labeled or skipped products. Generally this will not be a problem

since it will take some time to correct the problem, press alarm reset, and bring the primary

applicator back online.

• If either applicator is powered down, the other applicator will not receive product detect signals.

Disconnect the crossover cable between the applicators when performing service on one of the

applicators or when crossover is not being used.
