EZ-SCREEN SLS is typically used for, but is not limited to, the following applications:
Small assembly equipment
Automated production equipment
Robotic work cells
Molding and power presses
Assembly and packaging machines
Lean manufacturing systems
Do not use EZ-SCREEN SLS in the following applications:
With any machine that cannot be stopped immediately after a stop signal is issued, such as single-stroke (or full-revo-
lution) clutched machinery
With any machine with inadequate or inconsistent machine response time and stopping performance
With any machine that ejects materials or component parts through the defined area
In any environment that is likely to adversely affect photoelectric sensing efficiency. For example, corrosive chemicals
or fluids or unusually severe levels of smoke or dust, if not controlled, may degrade sensing efficiency
As a tripping device to initiate or reinitiate machine motion (PSDI applications), unless the machine and its control
system fully comply with the relevant standard or regulation (see OSHA 29CFR1910.217, NFPA 79, ANSI B11.19, ISO
12100, IEC 60204-1, IEC 61496-1, or other appropriate standard)
If an EZ-SCREEN SLS is installed for use as a perimeter guard (where a pass-through hazard may exist, see "Reducing or
Eliminating Pass-Through Hazards " on page 25 ), the dangerous machine motion can be initiated by normal means only after
the safeguarded area is clear of individuals and the EZ-SCREEN SLS has been manually reset.
Redundancy requires that EZ-SCREEN SLS circuit components be backed up to the extent that, if the failure of a single com-
ponent will prevent effective machine stopping action when needed, that component must have a redundant counterpart
which will perform the same function. The EZ-SCREEN SLS is designed with redundant microprocessors.
Redundancy must be maintained whenever the EZ-SCREEN SLS is in operation. Because a redundant system is no longer
redundant after a component has failed, EZ-SCREEN SLS is designed to monitor itself continuously. A component failure de-
tected by or within the self-checking system causes a stop signal to be sent to the guarded machine and puts the EZ-
SCREEN SLS 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" on page 85 .
