Introduction
This section contains mechanical and electrical installation procedures for the
MCP-25 control.

Installation of the
Scanner
The product scanner should be installed to detect the leading edge of the
carton. Up to four product scanners can be installed. A fifth scanner for the
encoder start signal can also be installed. The spacing between scanner and
valve should not be too small. For example, the spacing for a slow valve with
a turn-on reaction time of Ton = 10 ms depends on the parent machine
speed:
– 300 m/min = 50 mm
– 900 m/min = 150 mm
– 1800 m/min = 300 mm
The exact spacing in [mm] calculation:
Δ

=
Vmax [m] · Ton [ms]
; [mm]
60 [s]
A Valco VCE encoder, Valco VLD encoder, type 85 encoder, or type 30
encoder can be used with the control. One (1) encoder can be installed. A 1:1
ratio (1 impluse = 1 mm) between product travel and encoder impulse output
is preferred. A ratio of less than 1:1 (1 impulse = more than 1 mm) should not
be used because it will be less accurate. Product travel/impulse ratio can be
set in the “Setup menu.” (See
Section 11—Setup Menu for details about
encoder impulses per length traveled, maximum velocity, and direction
recognition.)
The direction recognition function
cannot be used with a VCE encoder.
The encoder should be installed so that it is synchronized exactly with the
machine speed. Ensure that the connection between the encoder and the
machine is secure and will not slip.
The contol can accept values in either
metric (millimeter) or imperial (inch)
measurements. This configuration
should be selected when the unit is
initially installed (see “Setup menu”).
Changing the measuring units after job
information has been stored in the
control may change the job values. The
control does not calculate anything
except encoder setup.
