1 Mount the transmitter and receiver sensors facing each other. Make sure the distance
between the sensors does not exceed the specified sensing range of the system.
2
Align the sensors by moving, either the transmitter or receiver sensor, horizontally and
vertically making sure they are pointing at each other until the output is:
- Deactivated when no object is present. (Dark operated)
- Activated when no object is present. (Light operated)
3 Fasten the transmitter and receiver sensors securely.
Avoid acute angles on cable close to sensor.
The transmitter power and 4 different channels can be selected. The channel is selected via
IO-Link and must be the same on corresponding transmitter and receiver. The transmitter
power is selected either with the white wire or with IO-Link. The power can be from 0 to 100 %.

Transmitter Power Adjustment SMT 9020C-IO / SMT 9070C-IO
Maximum transmitting power can be used for most applications. Maximum transmitter power
(factory set) is advised for applications with contaminated environments.
The transmitting power can be adjusted externally via the ‘White’ control wire of the transmitter
SMT unit. The transmitter level can be adjusted using a resistor (e.g. potentiometer) of 1.6k to
10K ohm or a voltage source of 0.5 – 2.0 V dc connected respectively between the ‘White’
control wire and – (negative) ‘Blue’ supply wires. Adjustment of transmitter SMT power may be
required in applications where objects to be detected are small or translucent.
Furthermore, the transmitting power can be adjusted via IO-link, under the parameter tab,
using the ‘Power value’ parameter and the ‘Power input’ parameter. From the factory, the
‘Power input’ will be set as ‘Cable’, i.e. the transmitting power is adjusted externally. To control
the power via IO-link, change ‘Power input’ to ‘IO-link’, and adjust the ‘power value’ parameter.
Proceed with the following steps:
1 Set transmitter power to maximum. The default setting is using the wire and it
should be 10K ohm or greater.
2 Select target object with the smallest dimensions and most translucent surface.
3
Place target object between transmitter and receiver sensors. If the output status
changes, adjustment is not required. If the output status has not changed proceed
to step 3.
4
Decrease the transmitter power (by reducing the resistance or lowering the ‘Power
value’) until the output status changes. If the output status has not changed, attempt
to move the sensors further apart or angle one of the sensors, and then repeat
procedure.
5 Remove target object. Observe the output status has changed.
