Appendix F

VFS Packaging Machine Metal Detectors

INTRODUCTION

VFS (Vertical Fill and Seal) E-Z Tec IV and V metal
detectors are mechanically and electrically identical
to standard units with the following exceptions:

•

The VFS units always have remote controls

rather than integral controls. This permits a lower
profile sensing head, and also allows installa-
tion in locations where a control integral with
the sensing head would be inaccessible.

•

The VFS units incorporate a round aperture,

sized to accommodate a 4" (100 mm), 6" (150
mm), or 8" (200 mm) nominal diameter pipe.

•

VFS units are offered with 4" (100 mm) and 6"

(150 mm) high sensing head housings to al-
low mounting in very restricted spaces.

•

VFS units are designed to NEMA 4 require-

ments and are sealed against hose-directed
water.

Because VFS units are intended to inspect falling
materials in a pipe or chute, there is no moving
conveyor involved, and, consequently, many of the
installation guidelines relating to conveyor
construction (in the main part of this manual) are
irrelevant. On the other hand, the build up of static
charges and vibration are of particular concern in
VFS installations.

The following sections provide pointers for obtaining
the best performance from your VFS E-Z Tec IV or
V. However, these sections are only supplementary
to the material in the main body of this manual,
which must be read and complied with for proper
installation, operation and maintenance of your VFS
E-Z Tec IV or V metal detector.

MECHANICAL

1.

It is important that you support the VFS unit

on stable structure that is not subject to vibra-
tion from other equipment.

2.

Do not allow other pieces of equipment to touch

the detector (or stand, if furnished). If it is nec-
essary to attach an auxiliary support or brace
to the stand, that support or brace must be elec-
trically insulated from the stand.

3.

The pipes or chutes that pass through the VFS

metal detector must be supported indepen-
dently of the metal detector and should be iso-
lated with flexible couplings that are appropri-
ate for the product application.

4.

User-supplied supporting structure must be of

continuously welded construction. Interrupted
welds or bolted joints can lead to intermittent
ground loops that will interfere with metal de-
tector operation and that will be very difficult
to identify.

5.

The remote control housing must be mounted

on the supplied electrically insulating mount-
ing feet. The remote control supporting struc-
ture should be stable, easily accessible, and
not subject to environmental extremes. If pos-
sible, mount the remote control outside high
pressure wash down areas.

6.

Equipment such as conveyor platforms and

supports must be kept out of the prescribed
metal free area for the metal detector.
