|
|||||||||||||||
Do not apply excessive impact on the sensor during the installation process, so as to prevent damage or deterioration in the degree of protection.
To install the sensor, tighten the mounting screws to a torque of 0.5N m or less. (Fig.1)
Install the Background suppression type sensor head perpendicular to the object transfer as shown below to minimize sensing errors. (Fig.2)

5Notes for Operation
Do not use the sensor during the transient time of 100 ms after turning on the power supply.
If the sensor and the load are connected to different power supplies, the sensor must always be turned on first.
Do not install the sensor outdoors, nearby induction device, or heat source. Choose locations free from frequent vibrations, shocks, dust, toxic gases, water, oil, and chemicals, so as to prevent malfunctions and damage.
Do not expose the sensor to sunlight or other direct light projections.
Do not use the sensor with drops of water remaining on the lens or aperture of slits.
In case installing the reflector of polarized retro-reflective type, make fine adjustment of angle or position of the sensor or reflector.
This product emits high directional beam. Therefore the beam possibly be out of alignment by the mounting condition. Make sure to adjust the beam axes alignment before use.
CAUTION
Do not connect the sensor to AC power supply, so as to prevent explosion and burning.
6Wiring
Turn off the power supply before wiring.
Connect correctly to prevent damage.
The power voltage must not exceed the rated range.
When using a switching power supply, be sure to ground the FG (frame ground) terminal.
Do not install the sensor wiring in the same conduit with high-voltage lines and power lines.
Cable extension is allowed up to 100m using a cabtyre cable with core wires of 0.3 mm2 or more.
To connect the sensor with connector cable, tighten connector to a torque of 0.5N m or less.
Use a UL Listed (CYJV/CYJV7) mating connector/cord assembly when using connector type as UL/c-UL listed products.

7 Adjustment for Background suppression type
Step Distance Control |
Adjusting Procedure |
|
|
Install a photoelectric sensor and the sensing |
|
1 |
object. Turn the control counter-clockwise until |
|
the operation LED turns OFF (*1). Then turn |
||
|
||
A |
clockwise until the operation LED turns ON |
|
(point A). |
||
|
||
|
Remove the sensing object, then the operation |
|
2 |
LED turns OFF. Turn clockwise until the |
|
B |
operation LED turns ON (The background is |
|
A |
detected) (point B). (*2) |
|
|
Set the middle point between point A and B as |
|
3 |
||
point C. (*3) |
||
B |
|
|
A |
|
|
C |
|
*1: If the operation LED turned off, turn on by turning the control clockwise.
*2: Make one turn or more clockwise from point A and set the position as point C when the background is too far and the operation LED dose turn ON.
*3: There may be more than 1 turn between points A and B, since this photoelectric sensor incorporates a 6-turn adjuster.
