In this HOW TO video, we will cover the basics of wiring and setting up one of AutomationDirects
Advanced Area Sensors from the brand Micro Detectors.
I am currently using model number shown: CX2E0RP-10-016V with PNP output and 0 to 10 volt analog
output.
These come as a pair with an emitter and a receiver.
The Micro Detector area sensors we sell at AutomationDirect all require a connecting
cable.
Make sure you select the correct cable with correct
number of pins in either a straight or a ninety degree
connector.
The sensors I am using require a 4 pin 12mm connector cable for the Emitter and an 8 pin
12mm connector cable for the receiver, I am using the part numbers listed on the screen.
Keep in mind; we sell many cables that will work depending
on your application and environment.
We have 90 degree connectors, straight connectors; harsh environment
insulation, shielded cables and they all come in
many different lengths.
Just make sure you select the correct number of poles or pins for your sensors.
If you have questions, use a multi meter and check the pinout or call our free technical
support here at AutomationDirect.
I follow the wiring diagrams for these sensors, it can be found in the documentation that
comes with the sensor, or you can find it on our website.
The emitter has 4 connections.
Brown for positive voltage and Blue for negative voltage or common
to power the sensor.
White should be connected to the Orange wire on the Receiver.
Black is a test wire and is not required but if needed, connect it to
positive voltage and it will interrupt the emission.
In this example, I left the black wire disconnected.
Now let's wire the receiver.
The receiver has 8 connections!
8 connections on a sensor is quite a bit, so
please pay close attention when wiring to avoid mistakes and frustrations.
Brown for positive voltage and Blue for negative voltage or common to
power the sensor.
The Black wire on the receiver should be connected to your output device and wired
as PNP.
In this example I have the black wire connected to
the positive input on a WERMA Stacklight that we sell here at AutomationDirect.
Make sure you check the specs of your device: I am using an LED
indicator because the Incandescent light required more
current than the sensor supplied, so we would not see an indication.
Next, the White wire is connected to my analog device.
In this example I am using a Pro Sense panel meter model DMP1 with 0-10 volt
input.
Our Gray wire should be wired to a switch or device to select Normally Open or Normally
Closed outputs.
In this example I have all of our selectable inputs wired to 3 way selector switches.
Pink is wired to a switch for Teach Gross or Fine.
Violet is wired to a selector switch for Blanking.
Last, Orange should be connected to the White wire on the
Emitter.
Now that our Emitter and Receiver are both wired, we need to check for alignment.
The user manual describes how to properly align the emitter
and receiver and what errors to detect if they are out of
alignment.
The manual also explains which LEDs you will see if your system is not wired properly.
We can now power the sensors and check for operation.
Once we power up, there is a time delay or "time delay before availability".
Once powered up and ready we can setup the sensor.
When the sensor is first powered up, we should only see a Blue LED on
the Receiver and a Yellow and Green LED on the Emitter.
Right now we have no power applied to the NO/NC feature, so the sensor defaults to normally
open meaning there is no output until the sensor
detects a part.
As you can see, when the sensor detects my screwdriver, our WERMA stacklight Blue
light turns on and I see a yellow and red LED indication in the Receiver.
Making changes to the NO/NC only takes place on power up.
If I attempt to change the setup after the sensor is powered up, nothing will change.
I must power down, select NC and repower the system and
now my Blue light stays on and I also see a Blue and Yellow LED in the Receiver when
no part is detected.
Once a part is detected, the Blue stacklight turns off and we see a Blue and Red LED in
the Receiver.
When the sensor detects an object, depending on its physical size, the sensor will send
an analog output value to our panel meter.
If the sensor detects the metal shaft of my screwdriver, we can see the analog
output is a smaller value than if the sensor detects the handle side of my screwdriver.
If we have a large object like a box, you can see the value
is even greater.
The analog out feature on these models are excellent for detecting correct parts
or defective parts.
Now let's discuss the Teach function.
This was where we wired the Pink wire on the Emitter to a switch
with either positive or negative input to the sensor.
Teach allows us to adjust for fine or gross sensing.
As you see, when I select Fine or Gross, the yellow LEDs on the Emitter turns on until
the sensor has calibrated, then turn off.
Let's discuss quickly what Fine and Gross settings are: Gross Teach is used to
detect opaque objects and semitransparent objects with textured or corrugated surfaces.
Fine Teach is used when detecting small objects, or transparent
smooth objects like glass.
How you setup your sensors will be determined on your environment
and what type of objects you are detecting.
Our last selection on setup is Blanking.
This is a function that can be selected if the sensors may be
partially blocked by say a conveyor.
For example, the sensors are mounted and the lower 1/3 of the
sensor is blocked by the conveyor that will bring in products to detect.
We wouldn't want the sensor to detect the conveyor or its motion, so we would
select Blanking to tell the sensor NOT to use the lower
portion of the sensor.
As you can see I can demonstrate this with a simple post it note to tell the sensor
not to detect in this lower region.
Once Blanking is configured, the sensors will ignore the lower area.
Blanking like NO/NC is only read on Power Up.
Now our sensors are mounted, wired, setup, aligned and programmed and is ready to start
detecting product.
Now, what should we detect??
I hope this how to video was useful.
