Removing the Optional 6-Channel Expansion I/O Board
1.
Remove the HMI module. See Removing the HMI Module on page 6.
2.
Disconnect the cable between the CPU enclosure and the sensor. See Disconnecting the Cable
Between the CPU Enclosure and the Sensor on page 7.
3.
Detach the CPU enclosure from the battery compartment. See Detaching the CPU Enclosure from
the Battery Compartment on page 7.
4.
Remove the CPU enclosure cover. See Removing the CPU Enclosure Cover (Top) on page 10.
5.
Remove the adapter board. See Removing the Adapter Board on page 12.
6.
Remove the CPU board. See Removing the CPU Board on page 14.
7.
Remove the two standoffs closest to the connectivity board; these screw directly through the
board to connections on the CPU enclosure bottom.
The other two standoffs have separate screws underneath that hold them onto the expansion
I/O board. (If you are replacing the board itself because it failed, remove these standoffs and
screws as well so you can re-use them on the replacement board.)
8.
Carefully slide the 6-channel expansion I/O board out of its socket on the connectivity board and
set it aside.
Replacing the 6-Channel Expansion I/O Board
1.
If you removed standoffs that are held on the expansion I/O board, attach them to the new
replacement expansion I/O board. Torque standoffs to 1 to 2 in-lbs (0.1 to 0.2 N-m).
2.
Carefully slide the 6-channel expansion I/O board into its slot in the connectivity board and
make sure it is firmly in place.
3.
Secure the board to the bottom of the CPU enclosure by tightening the two standoffs that have
connections on the CPU enclosure. Torque standoffs 1 to 2 in-lbs (0.1 to 0.2 N-m).
4.
Attach the CPU board. See Replacing the CPU Board on page 16.
5.
Reattach the adapter board. See Replacing the Adapter Board on page 14.
6.
Reattach the CPU enclosure cover. See Replacing the CPU Enclosure Cover (Top) on page 11.
7.
Re-attach the CPU enclosure to the battery compartment. See Re-attaching the CPU Enclosure to
the Battery Compartment on page 9.
8.
Re-connect the cable between the CPU enclosure and the sensor module.
9.
Reattach the HMI module. See Replacing the HMI Module on page 6.
