INSTRUCTIONS FOR THE PROGRAMMING AND ADJUSTMENT
|
|
|
|
1 TRIMMER FOR THE SENSING RANGE ADJUSTMENT: The photocell is supplied with max. sensing range with the trimmer totally rotated in the clockwise direction. The sensitivity reduces by rotating the trimmer in the anti-clockwise direction.
|
|
2 SWITCH NO/NC: The photocell is supplied with switch in NO position (in absence of the object to be detected the output is disactivated). To change to N.C. (in absence of the object to be sensed the output is actived) turn the switch to N.C. in the anti-clockwise direction.
|
|
3 LED FOR INDICATION OF OPERATION: This indicates the output of the photocell, in the absence of the object to be sensed it is off with output N.O. and is on with output N.C. this changes state when the object to be sensed enters into the sensing area of the photocell.
|
|
NOTE! Before giving a power supply to the photocell it is recommended that the same unit be programmed by using the switch in the required function NO or NC.
|
|
NOTE! It is recommended that the trimmer and the switch be rotated very carefully by using a proper tool otherwise these can be seriously damaged. |
