• 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 pushbutton
within ten seconds to select desired type. Each press of the
button will cycle 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 ten
seconds after the last button is pressed.
Pushbutton Lock/Unlock
The pushbutton or remote teach (RT) can be used to prevent
unauthorized users from changing teach settings.
To lock the pushbutton: press and release the button three
times within three seconds. Both LEDs flash synchronously for
three seconds indicating that the pushbutton is now locked.
To unlock the pushbutton: press and release the button three
times within three seconds. Both LEDs flash asynchronously for
three seconds indicating that the pushbutton is now unlocked.
Permanent Lock: The pushbutton 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 pushbutton teach. For example, connect
to the +V for more than three seconds to align and install the
reflector, disconnect from the +V; while the reflector is in the
sensor’s field of view and there is no target, connect to the +V for
less than one second to complete the teach process. All
pushbutton functions can also be carried out via RT.
Wiring Diagrams
The quick-disconnect connector is shown in the following
diagrams. The pin numbers correspond to male connectors on
the sensor.
