SICK HTB18, Operating Instructions Manual

Page: 19 / 231

Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
Refer to graphic to check the function. If the switching output fails to behave in accor‐
dance with graphic, check application conditions. See section Fault diagnosis.
Sensor with potentiometer (without IO Link):
The sensing range is adjusted relative to the background with the potentiometer (type:
270°).
Clockwise rotation: sensing range increased; counterclockwise rotation: sensing range
reduced.
Turn the potentiometer clockwise until the yellow LED indicator lights up. When an
object is moved into the path of the beam, the yellow LED indicator must go out. If the
yellow LED indicator remains lit when an object is moved into the path of the beam,
repeat the adjustment.
Sensor with potentiometer (with IO Link):
The sensing range is adjusted relative to the background with the potentiometer (type:
270°).
Clockwise rotation: to teach mode; counterclockwise rotation: to run mode. Turn the
potentiometer clockwise to teach mode until yellow LED begins blinking. Set object
at desired sensing range. Turn the potentiometer counterclockwise to run mode until
yellow LED stops blinking. The yellow LED should remain lit. Remove the object from
light beam, LED will turn off.
We recommend placing the switching state in the object, e.g., see figure 6 . Once the
sensing range has been adjusted, the object is removed from the path of the beam,
which causes the background to be suppressed and the switching output to change
(see graphic C).

Set switching point
Figure 6: Signal strength light bar during adjustment
The optimum setting can be achieved and checked using the signal strength light bar
on the back of the sensor. The LEDs on the signal strength light bar light up in relation
to the object position and the set switching point. If no LEDs or only the red LEDs light
up, the object is positioned behind the set switching point and cannot be detected. The
first yellow LED lights up when the object is in the set switching point. The green LEDs
light up when the object is between the sensor and the set switching point. The closer
the object is to the switching point, the more green LEDs will light up (
see figure 6 ).
The sensor is adjusted and ready for operation. Refer to graphics see table 1, page 7
to check the function. If the switching output fails to behave in accordance the graphic,
check application conditions. See section Fault diagnosis.
Please refer to the enclosed operating instructions for the IO-Link photoelectric sensor
for information about adjusting the IO-Link sensing range.
