3.1.3 Control Reliability: Redundancy and Self-Checking

Redundancy requires that EZ-SCREEN LS Basic circuit components be backed up to the extent that, if the failure of a single

component will prevent effective machine stopping action when needed, that component must have a redundant counterpart

which will perform the same function. The EZ-SCREEN LS Basic is designed with redundant microprocessors.
Redundancy must be maintained whenever the EZ-SCREEN LS Basic is in operation. Because a redundant system is no

longer redundant after a component has failed, EZ-SCREEN LS Basic is designed to monitor itself continuously. A

component failure detected by or within the self-checking system causes a stop signal to be sent to the guarded machine and

puts the EZ-SCREEN LS Basic into a Lockout condition.
A recovery from this type of Lockout condition requires:

•

Replacement of the failed component (to restore redundancy)

•

The appropriate reset procedure

The Diagnostic Display is used to diagnose causes of a Lockout condition. See

Troubleshooting

3.2 Models

An EZ-SCREEN LS Basic Safety Light Curtain “System” refers to a compatible emitter and receiver of equal length and

resolution (available in pairs or separately) and their cordsets. Mounting hardware is ordered separately for each emitter and

receiver. Special-purpose mounting brackets are also available. Depending on the connection option, interfacing solutions

include IM-T-.. modules, redundant positively guided contactors, safety modules/controllers, and muting modules.
The 13 mm (0.5 in) minimum bend radius for all cordset models accommodates low-clearance installations; cords can exit to

the left, right, or back of the sensor, when mounting. The pigtail QD option is useful for connection to splitter cables or other

QD cordsets.
