The sensor does not read the Speed Sensor Input Signal
•
Check polarity and levels according to chapter 5.2.2, ”Speed Sensor Input”. Is the
speed very high? It should be max. 2.5 kHz.
There is an overcount (too few copies in the bundle)
•
Check the mechanical installation. The sensor must be parallel to the stream.
•
For cut-edge first delivery, or with copies with stitches or other non-folded edges, try
changing the application so that the Blocking Zone is greater, see chapter 6, ”SOFTWARE
FUNCTIONS”.
•
Back-edges could be counted. Check by running one paper at a time, and see if
there is an extra pulse sent at the end of the paper.
•
If the surface of the product is wavy, try tilting the sensor 5 - 10
°
according to figure
below.
Some products are not counted (too many copies in the bundles)
•
Check the mechanical installation. The sensor must be parallel to the stream.
•
Check the interface. See previous page.
•
If the product stream is very irregular, it could be that the sensor is blocking out
products coming too close. Try choosing an application with a shorter blocking, see
chapter 6, ”SOFTWARE FUNCTIONS”.
•
Make sure that the stacker has not got an internal Blocking Zone which is set in a
way that it blocks out pulses from the sensor.
•
If the product with the problem is very black and very thin, try lowering the sensor 10-
20 mm closer to the product stream.
•
Are the products very tilted when they pass the sensor? The max angle allowed is
15
°
for a 0.25 mm product.
•
Still Problem?
