4-in-1 Output
The 4-in-1 technology
offers a normally open or
normally closed output,
which automatically detect
their connected loads and either sink
current (NPN output) or source current
(PNP output). A single sensor with a
4-in-1 output can operate in four output
confi gurations, either NPN Light On, NPN
Dark On, PNP Light On, or PNP Dark On.

ML7 Programming
(not on ML7-8-H models)
1. With the sensor connected to the specifi ed supply
voltage, aim the sensor’s light beam at the target
for diffused mode, at the refl ector for retro-refl ective
mode, or align the transmitter and receiver for thru-
beam mode.
2. Press the teach button once. The green LED will
turn off and on again to acknowledge this step.
3. Press and hold the teach button until the green and
yellow LEDs blink simultaneously (2 Hz frequency).
The green and yellow LEDs will then blink
alternately (2 Hz frequency) to indicate an internal
set-up procedure.
If the teach is successful, both the green and yellow
LEDs should be on continuously. The green LED
indicates power is supplied to the sensor, and the
yellow LED indicates if light is received.
If the teach is not successful, then both the green and
yellow LEDs blink alternately at a faster rate (4 Hz
frequency) for about 5 seconds and the sensor will
return to its maximum sensitivity default setting. In this
case, steps 1 through 3 should be repeated.
The default setting for this series is maximum
sensitivity. If resetting the sensitivity to default is
desired, repeat steps 1 through 3 but with no target,
refl ector, or thru-beam alignment.
