Removing the Optional 6-Channel Expansion I/O Board

1. Remove the HMI module. See
2. Disconnect the cable between the CPU enclosure and the sensor. See
Between the CPU Enclosure and the Sensor
3. Detach the CPU enclosure from the battery compartment. See
the Battery Compartment
4. Remove the CPU enclosure cover. See
5. Remove the adapter board. See
6. Remove the CPU board. See
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
5. Reattach the adapter board. See
6. Reattach the CPU enclosure cover. See
7. Re-attach the CPU enclosure to the battery compartment. See
the Battery Compartment
8. Re-connect the cable between the CPU enclosure and the sensor module.
9. Reattach the HMI module. See
