8.12.2.2.2 Configuring a Base Unit as a Slave to the Expansion Unit

The TL881/TL891 base units are shipped configured as standalone systems. When they are used in conjunction with the MiniLibrary expansion unit, the expansion unit must control the robotics of each of the base units. Therefore, the base units must be configured as slaves to the expansion unit.

After the hardware and cables are installed, but before you power up the expansion unit in a MiniLibrary system for the first time, you must reconfigure each of the base units in the system as a slave. The expansion unit will not have control over the base unit robotics when you power up the MiniLibrary system, if you do not reconfigure the base unit as a slave.

To reconfigure a TL881/TL891 base unit as a slave to the MiniLibrary expansion unit, perform the following procedure on each base unit in the system.

1.Turn on the power switch on the TL881/TL891 base unit to be reconfigured.

____________________ Note _____________________

Do not power on the expansion unit. Leave it powered off until all base units have been reconfigured as slaves.

After a series of self-tests have executed, the default screen will be displayed on the base module control panel:
