System Settings 2
This setup menu is used to configure the trigger memory and trigger
clipping functions.
The trigger memory function allows the user to either apply or not apply
adhesive to products between the trigger and the guns when line speed
recovers after falling below the stop speed setting. When set to off, the
pattern is terminated, and when set to on the pattern resumes when the line
speed is above the start speed setting.
Clipping inhibits the pattern output if the product length measured by the
photosensor is shorter than the programmed pattern for a specific channel.
This feature is typically used to prevent glue from being applied to skewed
products. When pattern clipping is detected, a warning is displayed in the
Warnings screen and the warning relay is activated.

Tip Sealer Settings
This setup menu is used to configure the operation of the tip sealer output.
The tip seal output is capable of driving a 24 VDC solenoid valve. A
dedicated photosensor input in addition to the four-triggers has been
provided to trigger the tip seal logic.
The tip seal valve output operates in either automatic mode or forced open
mode.
In forced open mode, the tip sealer output is continuously activated.
In automatic mode, the tip sealer output is activated prior to any gun
being activated. The output is also activated when triggered by the
tip seal photosensor or the assigned channel trigger. If a trigger
signal is not received in a programmable period of time, the tip seal
output is deactivated.
