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).
c) Select: 6=Teach-In (Active High) in Channel 2 (SO2) 65 (0x41) sub index 1 (0x01).
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 will Flash with 1Hz (ON 100mS and OFF 900 mS).
2) Within 3-6 seconds the wire must be disconnected, and the yellow led will be flashing with 1Hz
(ON 900 mS and OFF 100 mS).
3) After a 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 cancelled do not remove the wire after 3 to 6 seconds but keep
the connection for 12 secs until the yellow LED is flashing with 10 Hz (On 50 mS and off 50 mS).

2.5.2. Teach from IO-Link Master

a) To enable Teach from the IO-Link master first disable the trimmer input:
Select: "0=Disabled" in the Selection of local/remote adjustment parameters 68 (0x44).
