IFM OJ Calibration

Pushbutton Calibration

Align sensor to point toward the object you wish to
1
detect. Fasten securely.
Push and hold button for about 2 seconds until the red
LED flashes. The red LED will go off and the yellow and
2
green LED will flash alternately.
Press button once with the object in place. The yellow
and green LEDs go off for about 1 second and then
3
flash alternately again.
Press button once without the object in place. The yellow
and green LEDs go off for about 1 second. When the
green LED comes on, the unit is in the operation mode. If
4
the red LED flashes after this step, calibration is not pos-
sible. This may be due to a marginal application or mis-
adjustment of the sensor. Adjust and retry the application.
The sensitivity can be set using the remote programming
wire (pin 2/white wire) instead of the pushbutton. To
activate remote programming, connect the wire to L+
for PNP sensors or L- for NPN sensors for the time
specified in the above steps.
Do not use a screwdriver
or other sharp object to
press pushbutton.
