capaNCDT CST6110
5.4.2
With Closed Housing
The distance between the sensor and the measuring object is not visible. You can determine the optimal distance between the sensor
and the measuring object using the
RAW
signal or the
Status
LED. Sensor and controller are connected with each other.
Possibility 1:
RAW SIGNAL
and
Oscilloscope
Open the controller housing. Use the MODE switch to select the operating mode
0
.
Use the
BLADES
switch to define the measuring object divider.
Connect the TTL (channel ) and RAW (channel II) signals to an oscilloscope.
Start to rotate the measuring object.
Screw a locknut on the sensor and carefully turn the sensor onto the thread of the hous-
ing.
The sensor position should always be fastened by the locknut, except while it is being
screwed onto the thread.
Check the RAW SIGNAL from the controller and optimize the distance between the
sensor and the measuring object.

The raw signal on the oscilloscope should already show a small signal
boost for each ridge/groove, distance between sensor and ridge ap-
prox. 5 mm.
Carefully continue to screw in the sensor.

The connector on the sensor cable can be turned in the socket
without needing to be pulled off. You can continue to screw in the
sensor while it is plugged in without the cable being twisted.

Once the raw signal includes clear signal boosts per ridge/groove,
pulse transformations can occur. However, if the controller's sensitivity
is too low, the raw signal is not transformed correctly. Pulse drops in the
TTL signal are gaps.
Continue to carefully screw in the sensor and/or increase the sen-
sitivity using the
Sens
potentiometer.
