WARNING:
• Install System Only on Appropriate Applications
• Failure to follow these instructions could result in serious injury or death.
• Use Banner's EZ-SCREEN only on machinery that can be stopped immediately after a stop signal
is issued at any point in the machine's stroke or cycle, such as part-revolution clutched
machines. Under no circumstances may the EZ-SCREEN be used on full-revolution clutched
machinery or in unsuitable applications.
• If there is any doubt about whether or not your machinery is compatible with the EZ-SCREEN,
contact Banner Engineering.
3.3.1 Examples: Appropriate Applications
EZ-SCREEN 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
3.3.2 Examples: Inappropriate Applications
Do not use EZ-SCREEN in the following applications:
• With any machine that cannot be stopped immediately after a stop signal is issued, such as single-stroke (or full-
revolution) 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, ANSI/NFPA 79, ANSI
B11.19, ISO 12100, IEC 60204-1, IEC 61496-1, or other appropriate standard)
If an EZ-SCREEN is installed for use as a perimeter guard (where a pass-through hazard may exist, see
Reducing or
Eliminating Pass-Through Hazards
on page 22), the dangerous machine motion can be initiated by normal means only
after the safeguarded area is clear of individuals and the EZ-SCREEN has been manually reset.
3.4 Control Reliability: Redundancy and Self-Checking
Redundancy requires that EZ-SCREEN 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 is designed with redundant microprocessors.
Redundancy must be maintained whenever the EZ-SCREEN is in operation. Because a redundant system is no longer
redundant after a component has failed, EZ-SCREEN 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 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 77.
