# 13 Manual Operations

- "Accessing the Main Door and AEM Door"

## Modes of Operation

Manual Mode

Manual operation may be required if the library has experienced an unrecoverable error or a library component requires service or installation. To perform manual operations, the library is placed in manual mode.

A library in manual mode cannot accept host requests (host requests may continue to generate and cartridge mounts and dismounts require human intervention). The library is in manual mode when a library main access door is open, a robot does not automatically mount and dismount cartridges, or the navigation tree in the SLConsole indicates that there is a problem with the library.

Maintenance Mode

Maintenance mode is active when a service representative enters the access door to perform maintenance or to replace a component. The library continues to operate and process host request.

## Safety Precautions when Entering the Library

WARNING: When entering the library, lock the access door open and retain the key to prevent accidental closure.

When entering a library, strictly observe the following safety precautions:

- Know the location of the emergency door unlocking mechanisms (see "Door Interlocks").

- Ensure the library is offline (see "Place the Library Online or Offline"). Do not enter the library or move any of the robot mechanisms if you have any reason to suspect the robots are online.

- Leave the access door open whenever working inside the library. This disconnects DC power and signal lines to the library's motors (see "Servo Power Interrupt").

- Know the location of the mechanical door releases. See "Mechanical Door Releases" for more information.

- Know the physical restrictions of the library. Be careful not bump your body against the arrays or to snag clothing on the arrays (only 0.4 m [18 in.] of aisle clearance).

- If you must move a robot avoid damaging the robot's mechanical or electronic components.

- If you are manually loading or unloading a cartridge, your hands must remain clear of the drive's mechanical and electronic load components.

### Doo r Interlocks

Door safety interlocks are located behind the front access doors of the base module and DEM. To open either access door, an access key is required.

Door safety interlocks are constantly monitored by the library controller. If an access door is opened during normal operation, an Emergency Robotics Stop condition is initiated and all library motors are immediately disabled. This prevents motors from operating while a library door is open. If the library is varied offline, opening the access door disconnects DC voltages to the rails and the power bus.

The door switches are also monitored when the library is powered off. A battery supplies power for the circuitry to detect a door opening/closing event while the library is powered off.

When a base module and DEM are connected together, opening an access door to either module automatically suspends operations within the entire library (the two door switches are connected in series).

### Servo P ower Interrupt

An additional safety feature is the servo power interrupt (SPI). If the library controller detects that a library motor is out-of-range, it will generate an SPI to turn off drive voltage to the faulty motor. This prevents a servo runaway condition until the cause of the problem can be determined.

### Mechanical D oor Releases

Each lock handle on the access doors of the base module and DEM includes a mechanical release which is painted yellow. This release serves as a safeguard in case a person is inside the library and the access door is accidentally closed and locked. When you push the release, it unlocks and opens the door.

## Powering the Library On or Off

Use the following procedures to power the library on or off.

### Power Off the Library

Use this procedure to power down the library.

1. Ensure all jobs have completed and quieces the library.

2. Take all library drives offline (see "Change a Drive Online/Offline Status").

3. Take the library offline (see "Place the Library Online or Offline").

4. Open the rear doors of the Base Module and DEM (if present).

5. Turn off the power enable switches.

6. If necessary, turn off the circuit breakers on the PDUs.

### Power On the Library

Use this procedure to power up the library.

1. Open the rear doors of the Base Module and DEM (if present).

2. If necessary, turn on the circuit breakers on the PDUs.

3. Turn on the power enable switches.

4. The library goes through the initialization sequence. If the access doors have been opened and closed, a full audit of the library will be performed.

## Accessing the Main Door and AEM Door

Use these procedures to open and close the main library access door. Additionally, you can open the AEM door in emergency situations.

### Open the Main Door

1. Observe all safety precautions (see "Safety Precautions when Entering the Library").

2. Take all library drives offline (see "Change a Drive Online/Offline Status").

3. Take the library offline (see "Place the Library Online or Offline").

4. Insert the key into the door lock, and turn the key to unlock the door.

5. Pull up on the door latch to release it, and open the door.

6. Turn the key in the lock, to lock the door open, and then remove the key from the lock and keep it with you. This will prevent the door from being closed while you are in the library.

7. Enter the library.

### Close and Lock the Main Door

Use this procedure to close and lock the main doors of the library. When you close the access door, the library will perform a full audit.

1. Verify that there are no loose items in the library.

2. If the access doors were locked open, insert the key into the door lock, and turn the key, to unlock the door.

3. Push the door closed and make sure it latches securely.

4. Turn the key in the lock, to lock the door closed.

5. Remove the key from the lock and keep it in a safe place.

6. If the library has been powered off, power it on. See "Power On the Library"for details.

### Open AEM Door for Emergency Access

Use this procedure to gain emergency access to the AEM.

Caution: This procedure has the same effects on library operations as opening the main library access door. It causes an abrupt interruption of library activity. This procedure does not lower the internal AEM safety door.

1. Insert the library access door key in the Deadbolt Override lock, and unlock the door by turning the key clockwise. The key cannot be removed from the lock while it is in the unlocked position.

2. Lift the AEM access door latch, and open the door. DO NOT force the AEM access door to open or close.

   All power to the robots is stopped immediately. All in-process jobs are stopped abruptly, and the robots and AEM CAPs are brought offline.

### Close AEM Access Door

Use this procedure to close the AEM access door and re-initialize the library after performing an AEM emergency access. This procedure initiates a full audit of the library.

1. Close and latch the AEM access door. DO NOT force the AEM access door to open or close.

2. Lock the door by turning the key counter-clockwise in the Deadbolt Override lock.

   1. The library re-initializes.

   2. The robots go through their initialization sequence.

   3. A full audit of the library is conducted.

   4. The AEM CAP is brought online and returned to its default state.
