9.: Set sensitivity:
Depending on the currently sensitivity value, the positioned object can switch the relay ON via
the sensor electrodes, or the relay remains switched OFF. The red LED5 lights up to indicate
when the relay is switched ON.
In any case, the sensitivity must be set to match the working object as described below.
!
For proper functionality, the
sensitivity
should only be set
as high as necessary!
There are two possible methods of setting the sensitivity:
1.
Automatic:
The evaluation unit adjusts the sensitivity to match the positioned object in the
detection area. If the relay was previously switched OFF, it switches on. If it was
already ON, it will keep ON until the object is removed.
The procedure is as follows:
– Place the object in the detection area.
– Press button SW1 for 2s… 3s
After 2s, LED2 lights up indicating 2s gone.
– Release button SW1.
LED2 goes out. You now have 3 seconds to move away from the area of the
sensor electrodes, so that, your presence does not influence the measure-
ment of the object.
When 3s are done, the optimum sensitivity for the working object is set. LED2
confirms the process by flashing briefly.
2.
Manual:
–
Relay OFF (LED5 OFF):
Rotate the switch SW1 clock-wise until the relay switches ON, plus three
more points.
–
Relay ON (LED5 ON):
Rotate switch SW1 anti-clock-wise until the relay switches OFF (LED5 OFF),
then return until the relay switches ON again (LED5 ON) plus three points.
Case the current sensitivity shows impractical, it can be adjusted manually at any time by turning
the switch SW1.
The new sensitivity setting is saved and also effective by the next time the evaluation unit is
switched ON.
Function Explanation (Turning OFF without memorization)
Case the detector device is switched OFF while the memory function is inactive and an object is left
in the detection area, the device “ignores” this condition. In this case, when the device is switched
ON again, it will proceed with a new adjustment considering free detection area and the relay will
stay OFF.
To be sure about this procedure, one can move his hand to the detection area to see the relay turning
ON. After removing the object and subsequently the hand from the detection area, the relay turns
OFF again and around 2s later the new conditions will be detected by the device as empty area.
