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.
