INSTALLATION
ORIGINAL INSTRUCTIONS 57
- In the immediate proximity of the Metal Detector, the motors may be screened by means of
cylindrical metal enclosures; such cylinders must have a sufficiently large diameter to contain
the motors and a thickness of not less than 2 mm. The cylinders must be of the non-welded
type.
- Use shielded cables for the motor, connecting the shield to earth on the Metal Detector side
only.
- In the case of motors driven by an inverter, keep the frame of the motor insulated from the
conveyor belt frame, and connect it to earth only using an earth connection towards the
inverter. If the inverter is placed near the Metal Detector, install it inside a metal container
and screen any control cables which pass near the Metal Detector.
3.1.3.5 Selecting and installing connecting cables
The following instructions refer to connecting cables to external equipment and servo systems.
- Only use cables with a circular cross-section and a smooth surface.
- Only connect one cable to each cable gland.
Cable gland Only cable with an outer diameter between:
M16 ø3.0 - ø10.0 mm
M20 ø5.0 - ø13.0 mm
M25 ø8.0 - ø17.0 mm
3.1.3.6 Multiple Metal Detectors close together
To prevent reciprocal interference between Metal Detectors which are positioned close to each
other, set different transmission channels for each detector. The minimum distance depends on the
antenna dimensions and on the Metal Detector settings.
The command for assigning a different channel to a Metal Detector is Configuration > TX
Channel.
To identify sources of electrical and mechanical noise which might disturb operation of the Metal Detector, see the
instructions in the Compatibility Procedure (section 5.5).
3.2 Unpacking
Store the system in its original packaging, or in a way that protects it adequately from atmospheric
agents or other possible causes of damage (moving objects, weights, solvents etc.).
3.2.1 Metal Detector
3.2.1.1 Handling and moving the packaged device
Handle the package with care and without excessive force during
movement.
To move and handle the packaged device, use a forklift truck with a
sufficient load-bearing capacity. Ensure that the load is balanced during
handling and transport.
Other transport methods are forbidden.
Place the equipment, still in its package, as close as possible to the final
installation site.
