Installation
48
Do not start the machine and initiate the use of any electrical circuitry before the Loma
commissioning engineer has approved the installation.
Checking Guards
Check that all guards are securely fastened in place.
On some conveyors that are made to special order, hatches may be fitted to permit access
to some areas of the machine. These hatches are generally fitted with electrical interlocks
which prevent the machine from operating whilst a hatch is open. Check that all hatches are
closed.
Check that the infeed and outfeed areas of the conveyor are clear of obstructions.
Checking Belt Tracking (PV belt system only)
The belt must be checked for correct tracking before running the conveyor for any length of time. If
belt tracking needs to be reset. See
Conveyor Belt Maintenance
for further details.
Setting Up Reject Mechanisms
The conveyor system is supplied with the reject mechanism correctly set up. Normally, no further
adjustment should be required. If adjustment is required see
Adjusting the Reject Mechanisms
for
further details.
If the reject Delay and Dwell times need to be adjusted, these are set up via the user interface from
the control panel. See
Adding a New Product
for further details.
Remote User Interface
The electronic controls for the metal detector are integrated into the search head along with the user
interface, but the user interface can be mounted remotely in it‘s own housing where access would
otherwise be difficult.
Two versions of remote user interface are available, one with an on-board power supply and one
without. The model with the on-board power supply must be used where the cabling between the
search head and user interface exceeds two metres in length.
Care must be taken when routing the cabling to the remote user interface to observe good EMC
practice – do not run with mains or high energy switching cables.
Installing a Serial Link
The main control electronics board must have the optional serial link board fitted.
In order to use any of the serial link options your detector will require a cable and connector assembly
which facilitates external connection to the on board serial link electronics. The connector is normally
located on the underside of the control box.
If a serial link option was ordered with your detector the necessary internal cables and external socket
complete with a blank mating external plug and connection diagrams will be supplied. If you wish to
add a serial link to an existing system please contact your local Service Centre who will be pleased to
assist. See the Setting Up Serial Links section for further details.
Site Considerations
Electromagnetic Compatibility (EMC)
All Loma machines are designed, and tested, to operate under factory conditions and have been
tested to recognised international standards for Electromagnetic Compatibility (EMC), both in terms of
not emitting excessively and not being subject to undesirable operation in the presence of other
equipment whose emissions also meet the standards.
