Chapter 3: Installing the FT-50
3-21
Install the High-Resolution Encoder
If you will be using the High-Resolution Encoder option with your
FT-50, install the encoder so that it is driven by the sprocket shaft
that drives the conveyor chain section that passes through the
inspection system. This ensures that the encoder is rotating at the
same rate as the conveyor drive shaft.
The preferred method for mounting the encoder is inline, directly
attached to the shaft. If you are unable to mount the encoder inline
you can use an offset mount. Refer to drawing I-00484 in the Service and
Installation Drawing Pack for more information on installing the encoder.
Mounting the Encoder Inline
1. Drill and tap a 1.5-13 unc x 0.65 inch (M12-6G x 1.65 cm) hole
into the sprocket shaft to mount the coupling stud.
2. Insert the coupling stud into the sprocket shaft using Red
Loctite #271, or an equivalent adhesive.
3. Drill the encoder bracket mounting holes as shown on drawing
I-00484. There are two drilling templates, choose the one that
suits your installation.
4. Attach the encoder assembly by sliding the flexible shaft over
the coupling stud and securing the encoder with the included
screws and the shaft with the included hose clamp.
5. Attach the signal cable to the FT-50 by routing it through the
watertight port in the bottom of the FT-50 and attaching the
wires to the TB4 terminal bracket.
