(4) Remove the seven screws (XA1-1260-406) and washers (XD1-1102-625) to remove the
31PCB-AD2 from the sensor unit.
(5) Attach the new 31PCB-AD2 to the sensor unit. Temporary tight the seven screws
(XA1-1260-406) and the seven washers (XD1-1102-625) so that the 31PCB-AD2 can
move.
(6) At installation of the flat cable (FPC-A-AD), reverse the step (3). Make sure the dust and
any foreign materials are not attached to the flat cable (FPC-A-AD) and the connector.
Gradually tighten each of the screws uniformly to prevent the deflection of the connector.
Note:
The flat cable (FPC-A-AD) has multiple pins (120pins) with high density. Be aware that
the dust in the connector and the deflection of the connector may cause the connection
failure.
