8.5. 8.5. 8.5. 8.5. Detection Method Detection Method Detection Method Detection Method
There are four detection methods for the article.
Detecting the front of the article with the position sensor.
Detecting the end of the article with the position sensor.
Detecting gross above the zero band.
Detecting gross within the zero band.
Place the position sensor at the front of the weighing conveyor.
The position sensor is assumed to be a photoelectric sensor or laser sensor
Use the
Chattering timer
[
5q f-42
] to prevent an error.
Use the
Eval delay timer
[
5q f-43
], when the article is detected.

Procedure:
1 The front of the article crosses to the position sensor.
2 When the sensor output changes from OFF to ON,
Chattering timer
[
5q f-42
]
starts.
3 When
Chattering timer
[
5q f-42
] is up,
Eval delay timer
[
5q f-43
] starts.
4 When
Eval delay timer
[
5q f-43
] is up, the detection has effect.
Memo
If the article is packed in a clear bag, use a long delay time to prevent an error with
Chattering timer
[
5q f-42
].

The tolerance of
Eval delay timer
[
5q f-43
] is wide, because the timer starts
after the article is put on the weighing conveyor that moves in various velocities.
Procedure:
1 The end of the article crosses to the position sensor.
2 The sensor output changes from ON to OFF.
3
Eval delay timer
[
5q f-43
] starts.
4 When Eval delay timer [
5q f-43
] is up, the detection has effect.
