Removing a PTM
To remove a PTM:
1.
Access the rear panels of the Library units in the storage cabinet and disconnect each one
from its AC power source.
2.
Unplug the motor control cable from its connector on the PTM motor housing assembly
(see Figure C-13).
3.
If the master unit (top) is to be removed for service, disconnect the motor cable and plug it
into the unit directly below it (slave 0). Reconfigure slave 0 to be the master unit and slave
1 to be slave 0, slave 2 to be slave 1, and so forth (see Figure 3-5).
NOTE:
After installation, there are software ramifications in changing a Library’s configuration and
should only be done if necessary.
4.
Disconnect the RJ45 cable from the unit to be removed or serviced and then plug it into
the next unit so all units remain in series.
