Cylinder sensor with IO-Link

MK59xx

19

If SSC1.1 is taught, only the minimum end position will be monitored.
If SSC1.2 is taught, only the maximum end position will be monitored.
If both switching signal channels are taught, both end positions will be monitored by opposite
switching behaviour and the display of both LEDs.

If the LEDs do not match the position of the cylinder after teaching, the signal direction must be
inverted before teaching

.

To increase the switching zones for the end positions, there are the following possibilities:

u

Increase the hysteresis before teaching or manually shift the switch points after teaching

. In both cases, the automatically set times [Reference actuator

runtime] and [Tolerance actuator runtime] are no longer correct and must be re-configured.

9.3 Switch point logic

The switch point logic of the switching outputs can be set.

Selectable values:

[High active] = normally open

[Low active] = normally closed

u

Select [Parameter] > [SSC1.x].

u

Select [SSC1.x Config. Logic] and set the switch point logic for the switching signal channel
SSC1.x.

9.4 Switching delay

For both switching signal channels, a separate delay time can be set for the output to switch and to be
reset.

A switching delay can be useful in the following cases:

The switch-on and switch-off delay can be used as a filter, for example, to block out magnetic
interference fields caused by short-time high currents.

The switch-off delay can be used as a signal extension.

With a switch-on delay, a signal can be faded out if the corresponding area is only passed over.
The signal will only be output when the application comes to a standstill in the corresponding area
or after a corresponding time.

Use in welding applications:
To suppress interference from high AC welding currents, the switch-on and switch-off delay
must be set to a value greater than 20 ms.

Parameter setting:

u

Select [Parameter] > [SSC1.x].

u

Select [SSC1.x Switch-On delay] and set the time for the switch-on delay.

u

Select [SSC1.x Switch-Off dela] and set the time for the switch-off delay.

9.5 Signal direction

Depending on the orientation of the magnet, the slope of the signal may vary.

With the following signal, the sensor behaves according to Function Class "Object Detection":

The process data value (PDV) becomes smaller as the target approaches the sensor.
