Electrical
connections
are made through M12 (or Euro-style)
quick-disconnects. An
optional
hookup that provides sensor
interchangeability (or “swapability”) – the ability to install either
sensor at either QD
connection
– is possible. Using a parallel
connection
(color-for-color), the
emitter
cable can be connected
to the receiver cable, providing the ability to swap the
emitter
and
receiver
position,
similar to a popular feature of Banner MINI-
SCREEN
®
safety light screens. This hookup
option
provides
advantages during
installation,
wiring, and
troubleshooting.
All models require a supply voltage of +24V dc ±20%.

Section
Carefully Before Installing the System
If all
mounting,
installation,
interfacing, and checkout procedures are not followed properly, the Banner device
cannot provide the
protection
for which it was designed. The user has the responsibility to ensure that all local,
state, and
national
laws, rules, codes, or
regulations
relating
to the
installation
and use of this control system in
any
particular
application
are
satisfied.
Ensure that all legal requirements have been met and that all technical

and maintenance
instructions
contained in this manual are followed.
The user has the sole responsibility to ensure that this Banner device is installed and interfaced to the guarded
machine by
Qualified
Persons
1
, in accordance with this manual and applicable safety
regulations.
The Banner EZ-SCREEN Type 2 Light Screen is intended for lower-risk machine guarding and other safeguarding
applications
, as
determined by a risk assessment. It is the user’s responsibility to verify whether the safeguarding is appropriate for the
application
and
is installed, as instructed by this manual, by a
Qualified
Person.
The EZ-SCREEN Type 2 ability to perform its safeguarding
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 Type 2 cannot provide the
protection
for which it was designed.
CAUTION: Install System Only on Appropriate
Applications
Banner EZ-SCREEN Type 2 is for use 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 Type 2 be used on
full-revolution
clutched machinery or in unsuitable
applications
as those listed. If there is any doubt about whether or not your machinery is
compatible
with the
EZ-SCREEN Type 2, contact Banner Engineering.
