6 Electrical installation
Operation in standard I/O mode:
The sensors must be connected in a voltage-free state (UV = 0 V). The following informa‐
tion must be observed depending on the connection type:
– Plug connection: pin assignment
– Cable: wire color
Only apply voltage/switch on the voltage supply (UV > 0 V) once all electrical connec‐
tions have been established.
The green LED indicator on the top of the sensor lights up.
Operation in IO-Link mode: Connect the device to a suitable IO-Link master and inte‐
grate in the master or control via IODD/function block. The green LED indicator flashes
on the sensor. IODD and function block are available to download from www.sick.com
under the part number.

6.3 Adjustments
L/D Switching
The sensor may be specified with a Light Switching or Dark Switching
(L/D) selection potentiometer.
Light Switching is selected for the Q1 output by rotating the poten‐
tiometer counterclockwise to the stop position. The potentiometer tab
will point toward the “L” printed on the sensor housing.
Dark Switching is selected for the Q1 output by rotating the poten‐
tiometer clockwise to the stop position. The potentiometer tab will
point toward the “D” printed on the sensor housing.
CAUTION
Over rotation of the potentiometer past the stop positions will cause permanent dam‐
age to the sensor.
If complimentary outputs are specified (Hx18-Pxxxxx, Hx18-Nxxxxx, Hx18-Fxxxxx), the
Q2 output will always be opposite switching state of the Q1 output. Therefore, the Q2
output will be Dark Switching when the potentiometer is in the “L” position and Light
Switching in the potentiometer is in the “D” position. If bipolar outputs are specified
(Hx18-Axxxxx, Hx18-Bxxxxx), the Q2 output will always have the same switching state
as the Q1 output. The L/D selection potentiometer does not impact a Health or Alarm
output (if specified).

Q1 = L.ON
Q1 = D.ON
Time delay
The sensor may be specified with an adjustable time delay. The delay
time is adjusted by rotating the 270° potentiometer.
Clockwise rotation in the direction of the “+” printed on the sensor will
increase the delay time (TDELAY). Maximum Delay time will occur at the
clockwise stop position.
Counter clockwise rotation in the direction of the “-“ printed on the
sensor will decrease the delay time. There will be no time delay at the
counter clockwise stop position.
CAUTION
Over rotation of the potentiometer past the stop positions will cause permanent dam‐
age to the sensor.
A L/D selection switch may be specified with an adjustable time delay. Adjustable time
delay does not impact a Health or Alarm output (if specified).

7.1 Alignment
Sensor with red light:
Align sensor on object. Select the position so that the red emitted light beam hits the
center of the object. You must ensure that the optical opening (front screen) of the
sensor is completely clear [see figure 2].
Figure 2: Alignment
7.2 Check the application conditions
Sensing range
Check the application conditions: Adjust the sensing range and distance to the object
or background and the remission capability of the object according to the correspond‐
ing diagram [see figure 3] (x = sensing range, y = transition range between the set
sensing range and suppression of the background as a % of the sensing range (object
remission/background remission)). Remission: 6% = black 1, 18% = gray 2, 90% =
white 3 (referring to standard white as per DIN 5033). We recommend making the
adjustments using an object with a low remission.
The minimum distance (= y) for background suppression can be determined from
diagram [ figure 3 1] as follows:
Example: x = 100 mm, y = 10 => 10% of 100 mm = 10 mm. That is, the background is
suppressed at a distance of > mm from the sensor.

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).

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.
The sensor is adjusted and ready for operation.

7.4 Additional functions
Alarm / Health output
The sensor (HTB18(L)) features a pre-failure notification output (“Q2” in connection
diagram [B], if the alarm option is selected), which issues a notification if the signal
strength of the light being received is not sufficient. Possible causes: Sensor is conta‐
minated, sensor is out of alignment. In the good state: LOW (UV < V); if excessively
contaminated: HIGH (>+UV- V). The LED indicator flashes in this case.
Health output: The sensor (HTB18(L)) features a health status notification output (“Q2”
in connection diagram [B], if the health option is selected), which issues a notification if
the signal strength of the light being received is sufficient. Possible causes, if the signal
strength is not sufficient: Sensors are contaminated, sensors are out of alignment, or
cable is damaged. In the good state: HIGH (>+UV- V); if excessively contaminated or in
the event of cable interruption: LOW (UV < V). The LED indicator flashes in this case.
Time types
Time types: HTB18(L) with optional On-delay or Off-Delay adjustment: t0 = no time
delay, t1 = time delay when object is detected, t2 = time delay when no object is
detected. The time setting can be selected using the potentiometer according to A.
Timer stages can be set from 0 to 2 seconds.
8 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
