Main PCB Assembly
a.
When the line replaceable unit 3004-0053 Main PCB Kit is supplied by Minelab no
assembly is required. However, in the event a main PCB is salvaged from one detector for use in
another, it is important to check for correct assembly before fitting the main PCB to the
detector. Check for correct assembly as follows:
•
Check that the six way ribbon cable is connected to the main PCB.
•
To connect the six way ribbon cable, separate the two halves of the PCB and open the
connector bail. Insert six way ribbon cable and close the connector locking bail.
•
Check the spacer toroid mid is in place between the two halves of the PCB.
•
Connect the two halves together and check the PCB interconnectors are aligned and fully
inserted.
•
Connect the 10 way ribbon cable, ensuring that the key on the connector is aligned with
the slot on the PCB.
