Removing and Replacing a PTM
To remove a PTM:
1.
Disconnect AC power from the Library units.
2.
Loosen the screws that secure the Library unit’s mounting ears to the front of the storage
cabinet.
3.
Loosen the rear slide screws so that the Library units float freely in the storage cabinet.
4.
Unplug the motor control cable from the PTM motor housing assembly (see Figure 5-41).
5.
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 5-41).
NOTE:
After installation, there are software ramifications in changing a Library’s configuration and
should only be done if necessary.
6.
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.
