Dosing System
The speed sensor is installed to detect filling line speed and
must be installed for the CryoDoser FleX system to operate
properly. Chart provides an additional PNP 12mm inductive
proximity sensor that may be used with the CryoDoser FleX
system
Installing the Encoder
For high speed lines where extreme accuracy is required
an encoder (Image 16) must be installed to increase the
resolution of the speed output for better performance of the
CryoDoser FleX at higher line speeds. The encoder provided
by Chart comes from the factory preset to 500 pulses per
revolution
Note: Only one channel is used to provide
necessary pulses for the CryoDoser FleX
system. For correct encoder functionality,
shielded cabling must be used. The
encoder should be grounded, either thru
the mounting bracket or separate ground
wire.

The encoder location should be accessible for installation
and maintenance. The location may be a spindle to spindle
connection where the encoder spindle may be integrated with
the filler/capper spindle.
Encoder Mounting Information
Ensure encoder is properly mounted and securely affixed so
it will perform at its optimum capability. Follow the drawing
below and mount with suitable hardware. Grounding is
achieved by proper mounting of the encoder case. Ensure
good electrical contact is made from the mounting flanges to
an earthed bracket or other grounded mounting means.
