FIGuRE 2
NOTE: Sensor placement is dependent on the application, whether web or sheet-fed type machines.
SENSORS
The PC210 utilizes the UH200 sensor pair (finished
in black). The sensor model is selected with a switch
located on the PC210 Setup Control inside the Cover
Panel.
The UH200 sensor operates at a frequency of 40kHz.
If two sets of sensors of the same frequency are placed
close together there is a possibility of interference of
the signals. To prevent this interference or crosstalk, the
sensors must be placed at least 80 in. [2m] apart. In no
event may the sensors be placed closer than 8 in.[20 cm].
WEB FED MACHINES
The Sensor must be installed where the web pass line
is stable and does not change. If possible, position the
Sensor between two closely spaced rolls on a vertical
web run. The Sensor must be set at least 2 in. [50 mm]
in from the edge of the web. NOTE: If several different web widths will run on the
machine the Sensor must be mounted where it will not
have to be moved when the web width is changed.
SHEET-FED MACHINES
Place the Sensor a minimum of 2 in. [50mm] in from the
edge of the sheet. The Sensor must be placed in an area
of the machine where the sheets are stable as they pass
through the Sensor beam.
