Powering-on the Library

▼ 

To power-on the library

If you DO NOT want to power-on the robots, CAPs, and the elevators, leave the 

doors open.

If the library has a 2N power configuration, you must switch on the system 

power on both the PDUs. 

See 

 for detailed illustrations.

Maintenance Mode of Operation

Maintenance mode is active when a service representative enters the access door to 

perform maintenance or to replace a component. 

An example of this would be the replacement of a defective HandBot when a 

redundant or operational HandBot is available. Each HandBot has two motors, if one 

fails, the other motor is powerful enough to move the defective HandBot into the 

forward service area. If both the motors fail for a HandBot, then the redundant 

HandBot moves the defective HandBot into the forward service area thus continuing 

HandBot operations. The service representative then requests that the library be made 

available for maintenance entry on the side where the HandBot is positioned. The 

maintenance key (available only to a service representative) is inserted, a service safety 

door moves to the side selected (partitioning the service area from operational library 

activity) and the HandBot is replaced.

The service safety door is not parallel to the front of the library; its right side is 

angled toward the rear of the library (see 

Service Safety Door Operation

During the replacement, the library continues to function. Because there are cartridge 

arrays in the forward portion of the Customer Interface Module, these slots are 

reserved for diagnostic and cleaning cartridges only. A mount request for a cartridge in 

the slot closer to the side (left or right) where the service safety door is engaged may be
