3 INSTALLATION
3.1 General Precautions
The DENEX Edge Detector II should be installed in an environment where:
1. The equipment ambient temperature does not exceed 40º C.
2. The equipment atmosphere is free from highly flammable or combustible vapors,
corrosive chemical flumes, oil vapor, steam, excessive moisture and particles.
Avoid mounting the unit in places with strong vibrations since they can produce miscounts,
especially when thin products are counted. Make sure that the mounting bracket and
means used are rigid to withstand vibrations.
3.2 Mechanical Installation
The sensor should normally be mounted on a flat conveyor. It is possible to mount the
sensor on a bent part of the conveyor according to figures below. Do not mount according
to Figure 3.2.1 (right) since it will deteriorate the function of the unit.
YES NO
Figure 3.2.1 Mounting on a non-flat conveyor.
The sensor should be mounted parallel to, and at a distance of 100 mm from the conveyor.
When the laser does not hit a product, it should hit a light, matte surface at 100 - 150 mm
below the sensor. The reference surface must be smooth. If the surface is wrinkled or
coarse, vibrations can cause error pulses. Also, make sure that dust and paper pieces do
not stay on the surface, since they could also create output pulses. Make sure that the
laser beam is properly stopped by this surface, so that it is impossible for a user to be
exposed to the laser beam.
