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 6.
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.
