TEACH mode
In the TEACH mode the switching size (switching point or display window) with and without air−save
function as well as the pressurization and evacuation times can be taught.
Note
Before teaching make sure that the desired switch function (window or threshold
comparator) and the desired hysteresis are set in the EDIT mode (è chapter 6.3 EDIT
mode).
Threshold value comparator
Window comparator
The (taught) switching point is derived from the
average value of both teach points. Calculation
formula: If both teach points are the same, the
following applies: SP = TP1 = TP2.
The taught switching window is derived from:
SP
min
= smaller teaching point (TP1 or TP2)
SP
max
= greater teaching point (TP1 or TP2)
