9.2.3 Teach In Application
During [Teach In Application], the switch point SP1 is automatically determined for the selected
switching signal channel SSC1.x: After moving the magnet back and forth three times, the sensor
detects the minimum and maximum measured value and thereby interprets the two end positions. The
switch point mode is automatically set to [Single Point] and the following settings are made:
• When teaching SSC1.1:
– [SSC1.1 SP1] = minimum measured value + hysteresis SSC1.1
– [SSC1.1 Config. Mode] = [High active]
– [ou1] = [SSC1.1]
– [Reference actuator runtime] and [tolerance actuator running time], see Stroke time monitoring
parameter setting ( Ò / 21) .
• When teaching SSC1.2:
– [SSC1.2 SP1] = maximum measured value – 2x hysteresis SSC1.2
– [SSC1.2 Config. Mode] = [Low active]
– [ou2] = [SSC1.2]
– [Reference actuator runtime] and [ Tolerance actuator runtime], see Stroke time monitoring
parameter setting ( Ò / 21) .
The minimum measured value and the maximum measured value must be at least twice the
value of hysteresis SSC1.1 and hysteresis SSC1.2 apart:
PDVmax - PDVmin ≥ (2x [SSC1.1 Config. Hyst] + 2x [SSC1.2 Config. Hyst]).

u
Install the device in the groove.
ü
Check that the current travel range of the cylinder is within the
limits of the measuring range.
u
Select [Parameter] > [Teach] > [Teach Single Value].
u
Select [TI Select] and set the switching signal channel
[SSC1.x].
w
The following teach will be executed for the selected
switching signal channel.
If [TI Select] = [all SSC] is selected, the teach is carried out
for both switching signal channels simultaneously.
u Select [Parameter] > [SSC1.x] > [SSC1.x Config. Hyst] and set
the hysteresis.
u Select [Parameter] > [Teach] > [Teach Custom].
u
Execute command: [Teach In Application].
u
Move the cylinder back and forth between the end positions
(min/max). The end positions must be reached alternately
three times each.
w [TI Result. State] shows the status of the teach process.
w
The switch point SP1 is set for the selected switching signal
channel, the switch point mode is [Single Point] and other
parameters are set automatically (see above).
