EZ-SCREEN Point
Instruction Manual
System Installation
Read Section 3 in its entirety before installing the Banner
EZ-SCREEN Point System. The EZ-SCREEN System’s
ability to perform its safety guarding function depends upon
the appropriateness of the application and upon its proper
mechanical and electrical installation and interfacing to the
guarded machine. If all mounting, installation, interfacing, and
checkout procedures are not followed properly, the EZ-SCREEN
System cannot provide the protection for which it was designed.
Installation must be performed by a Qualified Person, as defined
in the Safety Glossary in this manual . See Warning at right .
3.1 Appropriate Applications
The EZ-SCREEN Point System may be used to guard only
machinery that can be stopped immediately after a stop signal
is issued. It may be used with part-revolution clutched machines
that have the ability to stop at any point in their stroke. Under
no circumstances may the EZ-SCREEN Point System
be used to guard full-revolution clutched machinery.
EZ-SCREEN Point Systems may not be used as tripping
devices to initiate machine motion (PSDI applications) on
mechanical power presses, per OSHA regulation 29 CFR
1910.217.
The EZ-SCREEN Point System is typically used in access-
guarding or perimeter-guarding applications for the following
types of machines:
• Assembly stations
• Manufacturing cells
• Automated production equipment
• Robotic work cells
WARNING . . .
Read this Section
Carefully Before Installing the System
The user is responsible for satisfying all local,
state, and national laws, rules, codes, or regulations relating to
the installation and use of this control system in any particular
application. Extreme care should be taken to meet all legal
requirements and follow all technical installation and maintenance
instructions contained in this manual .
The user has the sole responsibility to ensure that the Banner
EZ-SCREEN Point System is installed and interfaced to the
guarded machine by Qualified Persons in accordance with this
manual and applicable safety regulations.
Read all of Section 3 of this manual carefully before installing
the system. Failure to follow these instructions could result in
serious bodily injury or death.
CAUTION . . .
Install System Only on
Appropriate Applications
In order for the machinery guarded by the
EZ-SCREEN system to be stopped as described, that
machinery must be capable of stopping at any point in its
machine cycle. This means that the EZ-SCREEN system cannot
be used with certain types of machinery (see listing at left).
If there is any doubt about whether or not your machinery
is compatible with the EZ-SCREEN Point system, contact a
Banner factory application engineer.
3. Installation and Alignment
The EZ-SCREEN Point System may not be used in the
following types of applications:
• For finger or hand detection in point-of-operation guarding,
• To guard any machine that cannot be stopped immediately
after a stop signal is issued, such as single-stroke (or “full-
revolution”) clutched machinery,
• To guard any machine with inadequate or inconsistent
machine response
time and stopping performance,
• To guard any machine that ejects materials or component
parts through the area protected by the EZ-SCREEN beam(s),
or
• In any environment that is likely to adversely affect
photoelectric sensing system efficiency. For example,
corrosive chemicals or fluids or unusually severe levels of
smoke or dust, if not controlled, may degrade the efficiency of
the safety light grid .
