Installation and Alignment
EZ-SCREEN Grid
Instruction Manual
3. Installation and Alignment
Read Section 3 in its entirety before installing the Banner EZ-SCREEN Grid
System. The Banner EZ-SCREEN Grid 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 Grid 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 Banner EZ-SCREEN Grid 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 Grid System be used
to guard full-revolution clutched machinery. Banner EZ-SCREEN Grid 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 Banner EZ-SCREEN Grid 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
The Banner EZ-SCREEN Grid System may not be used in the following types of
applications:
• For finger or hand detection in point-of-operation guarding; its beam spacing is
larger than that allowed for finger or hand detection in these applications,
• For non-vertical area-guarding applications,
• 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 Grid, 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.
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 Grid 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 Grid 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 Grid 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
Grid system, contact a Banner
factory application engineer.
