About the Metal Detector Range
Reject Bins
Two sizes of reject bin are available for collecting contaminated products removed from the conveyor
belt using a pneumatic reject device. The size of the bin required is determined by the conveyor
length and the size and weight of the product to be rejected.
Reject bins are fitted with a lockable door as standard and optionally with an electronically operated
door lock mechanism that may be opened and locked by operators with a specific user level access
account through the user interface.
In addition the bin can optionally be fitted with a 'Bin Full' photo-eye which generates a warning when
the bin needs to be emptied. This option is enabled in the
Menus > Service > Reject > Set Up menu
A 'test' paddle can also be fitted to manually check that the Bin Full photo-eye is working correctly.
Electrical Services Box
Electrical supplies to the conveyor are connected inside the electrical services box. The box is
generally mounted at the front of the conveyor frame but can be overhead mounted. Supplies are
connected via the Isolator Switch. The internal components may be mounted on a printed circuit
board or on din rails if a PLC version is supplied.
The door of the box is fitted with the Isolator Switch, Conveyor ‘Stop’ and ‘Start’ buttons and the
Emergency ‘Stop’ button as described in the table below.
The Isolator Switch is located on the front of the Electrical Services Box and is shown
here in the ON position. Power is being supplied to the machine.
The Isolator Switch is shown here in the OFF position. Power is NOT being supplied
to the machine.
The conveyor Start/Sto p button is located on the front of the Electrical Services Box
and is used to start and stop the conveyor.
Pushing the green section at the top of the button starts the conveyor and the white
LED located in the middle of the button is lit to indicate this.
Pushing the red section at the bottom of the button stops the conveyor and the white
LED is extinguished.
The Emergency Stop button is located on the front of the Electrical Services Box and
is to be used in EMERGENCIES ONLY to stop the machine.
Guards
For Loma metal detectors the use of guarding, including covers, panels, curtains and other methods
is extremely important in order to restrict operators from accessing contaminated products and also
areas of the detector that are potentially hazardous.
Air Pressure Switch
An air pressure failure switch is fitted if the conveyor is supplied with either a pusher reject or a
retracting band reject.
