Construction of the Detector Installation
The design and construction of the metal detector
support framework will influence the performance of
the detector.
Follow the guidelines below to obtain the best
performance.
-
Insulate one end of the roller from the
conveyor frame.
-
This can take the form of a plastic insulation
plate and washers on the bearing mounting
block or a plastic extension to the end of the
roller shaft (see Fig. 6).
-
The conveyor frame should be of welded
construction rather than bolded sections.
-
Insulate/isolate all items bolted to the frame
(eg guards) using non-conducting insulators.
-
Mount the detector to its support framework
using the four plastic insulation sets supplied
with the detector.
-
Avoid passing metal conduit or electrical
cables through the metal free zone or near
the aperture of the metal detector.
-
See Appendix E for the theory behind the
construction of
the metal framework.
A typical installation is shown in Figure 5.
Positioning the Detector Head
Better sensitivity will be achieved if vibration from
other machines is isolated from the detector.
-
Avoid supporting the detector head on or near
vibrating structures and/or machines subject
to mechanical shock.
-
Position the detector head to allow easy
access to the control panel.
-
Position the detector to allow removal of the
control unit for servicing.
Electrical Connections
WARNING
If the detector is supplied as part of a system,
read all the system literature before
commencing electrical installation
In order to reduce the possibility of problems with
electrical interference, do NOT run any metal
detector cable next to other cables carrying switched
or heavy loads.
Electrical connections to the power unit are as
shown in Figure 8
Power connections to the power filter (where fitted)
are shown in Figure 9.
Arrangement of the gland assemblies for connecting
the power cable to the power supply unit are shown
in Figure 10.
Note. When installed correctly, the detector head
should be electrically insulated/isolated from the
support structure and connected to earth/ground
only through its own electrical connections.
These instructions are for connection to TN
(EN60950:1992) power distribution systems only.
For connections to other power distribution systems
please contact your supplier.
