2.5. Teach procedure

2.5.1. External Teach (Teach-by-wire)

NB! This function works in single point mode and only for SP1 in SSC1.
The Teach-by-wire must be set-up first using an IO-link master:
a) Select: "2=Teach by wire" in the Selection of local/remote adjustment parameters 68 (0x44).
b) Select: "1=Single Point Mode" is already selected in "SSC1 Configuration" 61(0x3D),
"Mode 1" 2(0x02), (this value should already be set as default).

Teach-by-wire procedure.
1) Place the target in front of the sensor and connect the teach-by-wire input (pin 2 white wire) to V+
(pin 1 Brown wire). The yellow LED LED will Flash with 1Hz (ON 100mS and OFF 900 mS).
2) Within 3-6 seconds the wire must be disconnected, and the yellow led is flashing with 1Hz (ON
900 mS and OFF 100 mS).
3) After successful teach the yellow LED will flash with 2 Hz (ON 250 mS and OFF 250 mS).
NB! If the Teach procedure is to be canceled do not remove the wire after 3 to 6 second but keep the
connection for 12 sec until the yellow LED is flashing with 10 Hz (On 50 mS and off 50 mS).

2.5.2. Teach from IO-Link Master
