12 Maintenance
The SCATEC-2 requires no maintenance apart from keeping the front windows clean. Dust or
fingerprints can impair the sensor function. It is normally sufficient to wipe the windows dry with a clean
(!), soft cloth. Alcohol may be used for heavy soiling.
The cover of the DIP switch must be mounted, otherwise dust might intrude. Dust inside the housing
can cause the sensor to malfunction.
13 Troubleshooting
Whenever possible use the application software ScaDiag for trouble shooting !
Otherwise first try to resolve the problem using the following tables. If this is unsuccessful, consult
Baumer Electric AG (
www.baumerelectric.com ) for technical support.
The search for fault causes can be substantially shortened if the following issues are clarified before you
make contact with a technician from Baumer Electric AG:
1. What is the part number and P-code of the sensor (see white area on the sensor label)?
2. Give exact description of the problem. (Does the SCATEC count more or less copies
than actually pass the sensor?)
3. Retain several samples of the products causing the counting error. (Mark the running
direction on one sample and the approximate line along which it passes the laser beam.)
4. If possible, take digital images of the installed sensor in operation and of the immediate
surroundings.

Fault Possible causes Corrective actions (see manual section x.x)
a) Wrong sensitivity setting. Set DIP-swich 4 off. (8; 9.3)
b) Copies too close to or too far away
from the Scatec, so that the copies
are in a distance range at which the
sensitivity of the sensor is inadequate. Set the distance of the copies in a range where
the sensor is sufficiently sensitive to detect the
copies. (10.6)
c) Overlap spacing sporadically too
small. Increase the overlap spacing or reduce the
conveying speed (production rate). (9.1)
d) Some copies are completely
covered by another copy. Prevent complete coverage of copies.
e) Conveying speed too high. Reduce conveying speed. (10.6)
1
Scatec counts less
copies than actually
pass the sensor
f) False pulse suppression active
while overlap a is highly irregular or
conveying speed is occasionally
accelerated very quickly. Deactivate false pulse suppression (DIP-switch 3
set off) or make overlap a more regular or
accelaerate slower (9.2)
