Relay contact information
If your metal detector is supplied with a reject device or any peripherals they will already be
connected.
However if you are connecting your own reject device refer to the voltage free relay
connection information given below. It is suggested that the reject device wiring is
connected in series with a set of fault relay contacts to enable the reject to be operated in
the event of a system fault being generated, ensuring failsafe reject operation for a fault
condition. Contact switching information is given in About the metal detector range, page 1.
Connections are made depending upon your requirement. Contacts shown are for relays
when de-energized (failsafe):
