Trigger (1 - 4) Configuration
After activating trigger’s 1 - 4 in the Trigger Assignment menu, this menu
serves to activate/deactivate the trigger and to define whether the product
or background should reflect. If the product is reflective, select the Light On
setting. Correspondingly, in the case of non−reflecting products, select the
Dark On setting.
If the jam detector is activated, a warning and signal are issued when the
photosensor is active for a period longer than the user-defined product
length plus the jam tolerance. In this case, the jam tolerance must be set for
each trigger.

Pressure 1 and 2 Settings
The pattern controller accurately regulates the system pressure to maintain
proper adhesive volume during line speed changes. This menu is used to
set the two-point linear pressure profile for each runup.
The linear pressure curve is defined by setting Speed 1 (S1) at Pressure 1
(P1), and Speed 2 (S2) at Pressure 2 (P2), see Figure 5.
Maximum and Minimum Line Pressure
The minimum line pressure is reached at the minimum cutoff limit, and the
maximum pressure is reached at the maximum cutoff limit. Pressure cannot
be set below the assigned minimum cutoff limit or above the assigned
maximum cutoff limit.
