Lsm Safety Features - StorageTek 4410 Hardware Operator's Manual

LSM Safety Features

Unless otherwise noted, the following items are standard safety features on the LSM.
• LSM Safety Interlocks—If the access door to the LSM is opened, electrical interlocks
remove power from the robot to prevent injury to someone.
• LSM Entrance Safety Sign—Just inside the access door to the LSM, a lit panel mounted
on the ceiling directs you to enter when the electrical interlocks remove power to the
robot, and all safety procedures have been followed.
• Prevention of LSM Access Door Closing—By following simple safety procedures (see
"Entering the LSM" in Chapter 3, "Operating an
can prevent anyone outside the LSM from closing the LSM access door.
• LSM Emergency Power Off (EPO) Switch—Pressing a large, bright red knob on the
inside of the LSM access door activates an EPO switch that turns off AC power to
the LCU/LSM. This extra safety feature is provided in case anyone outside the LSM
locks the access door when someone is inside.
• LSM Fire Detection—In the rare case of fire in the LSM, sensors start an immediate
subsystem shutdown (EPO).
• Internal Fire Suppression System Ports—The LSM contains ports to which the customer
may connect a fire suppression system. This system, as well as its controls and
sensors, is supplied by a third party vendor at the customer's request. A StorageTek
Marketing Representative can supply additional information.
• Theta Obstruction Search—During initialization, the robot theta arm moves slowly
through its full range of motion. In this mode, current is limited and you can stop the
mechanism by hand. If any physical obstruction prevents the arm from moving for
more than a few seconds, the arm shuts down and an error is posted. If motion is
disturbed only for a moment, the mechanism continues to sweep, but posts an error
at the end of initialization, without going into normal move mode.
À moins qu'il en soit précisé autrement, les points suivants constituent des dispositifs de
sécurité standard du LSM (Library Storage Module [Module d'archivage]).
• Verrouillage de sécurité du LSM - En cas d'ouverture de la porte d'accès au LSM, un
verrouillage électrique permet de mettre le robot hors tension pour éviter toute
blessure.
• Signal de sécurité d'entrée du LSM - À l'entrée du LSM, un affichage lumineux monté sur
le plafond indique à l'opérateur s'il peut entrer, une fois le robot hors tension et les
procédures de sécurité respectées.
• Prévention contre la fermeture de la porte d'accès au LSM - Tout individu à l'intérieur du
LSM peut interdire la fermeture de la porte d'accès au LSM depuis l'extérieur,
simplement en suivant les procédures de sécurité appropriées (« Entrer dans
le LSM »).
