b. If the load is connected for NPN configuration but to a
power supply other than that to the sensor or via a load
enabling contact (e.g. a relay contact in series with the load),
select dedicated NPN.
Selection can be made as follows:
1. To access output type: Press and hold the push button for 12
seconds (until both LEDs start flashing synchronously). Upon
button release, the current setting of output type is indicated
by the slow flashing of the LED(s) as follows:
• Auto PNP/NPN: both LEDs flashing
• Dedicated NPN: green LED flashing
• Dedicated PNP: yellow LED flashing
2. To change output type: Press and release the push button
within 10 seconds to select desired type. Each button
activation cycles to the next output setting. The type selected
is indicated by the LEDs. The sensor retains the setting per the
last button depression and returns to the RUN mode 10
seconds after the last button is pressed.
Push Button Lock/Unlock
The push button or remote teach (RT) can be used to prevent
unauthorized users from changing teach settings.
To lock the push button: press and release the button three
times within three seconds. Both LEDs flash synchronously for
three seconds indicating that the push button is now locked.
To unlock the push button: press and release the button three
times within three seconds. Both LEDs flash asynchronously for
three seconds indicating that the push button is now unlocked.
Permanent Lock: The push button may be permanently locked
by connecting the white wire (pin 2) to –V.
Remote Teach (RT)
The sensor can be taught remotely via the white wire (pin 2).
Connection to +V acts the same as the button being pressed and
no connection is the same as the button not being pressed. The
sensor can be taught by following the same teach/timing
sequence as used in the push button teach (e.g., connect to the
+V for more than three seconds to teach the “target,” disconnect
from the +V; remove the target and connect to the +V for less
than one second to teach the “no target” condition. All push
button functions can also be carried out via RT.
IO-Link
See instructions for IO-Link on www.ab.com . Remote Teach (pin 2)
is disabled in IO-Link operation. If output is selected as dedicated
NPN, IO-Link communication is unavailable.
