5 Freely configured sensor with Teach function
Set the following parameters:
• hysteresis / width of the window (SP1, rP1)
• OU2 = tch (pin 2 configured as teach input)
• Switching function for output 1 (OU1)
hysteresis function / N.O. (Hno)
hysteresis function / N.C. (Hnc)
window function / N.O. (Fno)
window function / N.C. (Fnc)
Additionally you can set:
• Delay time and damping for the switching outputs (dS1, dr1, dAP)
•
p-switching or n-switching
When using the hysteresis function (Hno or Hnc) set the hysteresis
by the difference between SP1 and rP1.
During the teach operation the switch-on point is set to the current
system pressure (P

If the hysteresis is greater than allowed for the switch-on point
(switch-off point would be below the measuring range), the teach
operation is cancelled (the sensor provides an error signal, → page

operation again.
