Rockwell Automation 45CPD Analog Laser Sensor - Manual (Page 3)

3
The discrete and analog output functions can be set in
combination (e.g., two discrete outputs and the analog output).
General Set Up
The 45CPD is set up using the pushbuttons (SET and  ) and the
LED indicators on the top of the sensor.
To begin the Teach-In process, Press the SET button for three
seconds.
This will automatically turn on the visible red alignment laser.
Scrolling through the Teach-In functions is done using the 
button. After the last function is reached the menu is started
again from the first function.
To teach the selected function indicated by the teach-in LEDs as
shown in table above, press SET for approximately three seconds.
The LED will blink three times when complete.
After the desired functions are set, press SET and 
simultaneously for approximately one second to exit the Teach-In
mode. The sensor will begin normal operation based on the
Teach-In settings. The visible red Class 2 laser will turn off and the
infrared Class 1 laser will turn on.
(Note: To reset the sensor to the factory setting, sensor should be
in the operating mode. Press the
 button for approximately 15
seconds until the menu LEDs turn on briefly.)
(Note: The Speed Mode of the 45CPD can be adjusted for either a
Fast or Slow mode of operation. The Fast mode enables faster
switching speeds which have a slightly lower repeatability. The
Teach-In Buttons/Indicators
The SET button sets the function that is currently indicated by the
Teach-In LEDs. To SET, press button for approximately three seconds
until LED blinks three times.
The  button advances to the next function. After advancing
through the entire menu, it will begin at the first function.

Slow mode has a slower switching frequency with higher
repeatability. Selection will depend on the requirements in the
application. The Speed mode is set by pressing the
 button until
the Speed LED (Orange) is blinking fast. To select the slower speed
function press SET and the Speed LED will blink approximately
once per second. To select the higher speed function, press SET
and the Speed LED will blink approximately three times per
second. To teach the setting for either slow or fast speed, press
SET for approximately three seconds. The four teach-in indicators
will blink three times when complete. When the sensor is put in
operation, the LED will be turned on when running in the Slow
mode.)
Modes of Operation for Typical Applications:
Object Detection—Single Output
To set the output for Q A there is a switch-on point indicated by the
A
S1
LED and a switch off point indicated by the A
S2
LED.
Once in the Teach-In mode press the  until the A S1 LED turns ON.
Position the target at the desired switch on point and then press
the SET button.
(If the target is not within the measuring range or cannot be
detected the A
S1 LED will blink.)
Press the  button to advance to the A S2 function which is
indicated by the teach-in LED.
Position the target at the desired switch off point and then press
the SET button.
If desired, the output can be inverted for this switching window
(L.O./D.O. function). Press
 until both the A
S1
and A
S2
LEDs are
turned ON and then press the SET button. This is also indicated
by the “INV” text on the teach-in pad.
After this Q
A
setting has been completed, press SET and 
simultaneously for approximately one second to begin normal
operation.
Object Detection—Dual Output
To set the output for both Q A and Q B , follow the same teach-in
procedure as the Q
A
Single Output (shown above) and
additionally teach the Q
B
output using the B
S1
and B
S2
LEDs.
