Fig.16: Monitoring the end position of the hydraulic valve
In the example, the plunger covers the sensing face of the device when the valve is closed. This state is
indicated via SSC1.1. SSC1.2 indicates when the valve is not securely closed.
Moreover, SSC1.2 is not to flicker every time the plunger passes over the sensing face. It is only to be ac-
tivated when the valve remains in the corresponding area for more than 500 ms.

Fig.17: Example: Monitoring the end position
Install and connect the device.
Set the valve to its closed position.
Read the current process data value PDV1 and write it down (30 in the example).
SSC1.1 Config. Select Mode and set Window.
Set the switch point SP1 manually: SSC1.1 Param.SP1 = 30 (PDV) – 10 (tolerance) = 20.
Set the switch point SP2 manually: SSC1.1 Param.SP2 = 30 (PDV) + 10 (tolerance) = 40.
SSC1.2 Config. Select Mode and set Single point.
SSC1.2 Config. Select Logic and set Low active.
SSC1.1 switches when the plunger is detected.
SSC1.2 switches when the plunger is not detected.
Calculate and set switch point 1: SSC1.1 Param.SP1 = 30 (PDV) + 10 (tolerance) = 40
SSC1.2 Delay. Select Switching delay and set 500.
The device only switches after 500 ms.
10.10.3 Displacement measurement in the end position
The measuring range of the device can be extended using a chamfered switching cam. The chamfer acts
as a transmission from a transverse to a longitudinal movement. The transmission ratio is set by the angle
of the chamfer.
In case of installation in the vicinity of brakes, pay attention to the maximum permissible tem-
perature of the device.
