Section 6 - Installation MC060 Manual/VC350AG AutoGlue Control System
If using a wheel-driven encoder, a VDD-1000 encoder with a 10-inch
measuring wheel is recommended for imperial measurement systems. A
VDD-250 encoder with a 250-mm measuring wheel is recommended for
metric measurement systems. Other options can be used for retrofits of
controls with existing encoders (Table 6-1).
Table 6-1 also shows what your resolution should be, based on the type of
encoder used. Once you have determined the resolution, a black marker
should be used to color in the decimal point on the front-panel pushwheels

not being used not being used not being used. See Section 7—Initial Setup, Figure 7-1. This leaves a white
decimal point in the correct position on each pushwheel pattern switch.
Table 6-1. Encoder Configurations
*Recommended
Table 6-1 is based on a 10-inch
measuring wheel (imperial) or a 250-
mm wheel (metric).
To install a wheel-driven encoder, follow these steps:
1. Mount the encoder’s bracket to the frame of the parent machine
so the encoder wheel rides on the drive belt as close to the glue
station as possible.
2. Ensure that the wheel of the encoder rides securely against the
belt and does not slip.
