About the Feelers
Feelers are an option. This machine may contain a
Length Feeler
, a
Thickness Feeler,
and/or a
Depth Feeler
. Verify the option included wit the machine and identify it in this section.
This machine may be equipped with quadrature encoders.
Quadrature encoders provide high speed bi-directional informa-
tion. Incremental encoders can provide a once-per-revolution
pulse (often called index, marker, or reference) that occurs at the
same mechanical point of encoder shaft revolution. This refer-
ence is used as a comparative point resulting in a highly accurate
measurement. The
encoder assembly
is identified as a
Feeler
.
Important:
If calibrating, calibrate the Feelers first.
See Chapter 3 in this manual.

About Door Length Feeler
The
Door Length Feeler
accurately senses the length of the door.
After the door has been fed in to the door
stop and clamped, the feelers “feel’ the
other end of the door. The location of the
stop and the machine encoders are com-
bine to calculate the exact length of the
door
