Cleaning the front screen:
² Use a clean and soft brush to remove dust from the front screen.
² Next, wipe the front screen with a clean and damp cloth.
9.2 Replacing the front screen
If the front screen is scratched or damaged, you must replace it. Order the
replacement front screen from Rockwell (see Section 12.2 “Accessories/
spare parts” on page 53).
Replacement of the front screen:
² Disconnect the system connector and remove the SafeZone safety laser
scanner.
² Take the SafeZone safety laser scanner to a clean place (office, repair
shop or similar).

ATTENTION Do not make any repairs to the device.
The SafeZone safety laser scanner does
not contain any repairable
components. For this reason do not
open the SafeZone safety laser scanner
components and only replace the parts
that are described in the following
sections as replaceable.
Switch the entire machine/system off
line.
The machine/system could
inadvertently start up while you are
changing the front screen. As a matter
of principle, always isolate the machine
from the power supply during all work
on the machine and safety laser
scanner.
IMPORTANT Static charges cause dust particles to
be attracted to the front screen. You
can diminish this effect by using an
antistatic plastic cleaner.
IMPORTANT
² The front screen on the SafeZone
safety laser scanner is an optical part
that must not be contaminated or
scratched.
² The front screen is only allowed to
be replaced by specialist personnel
in a dust- and dirt-free environment.
² Never replace the front screen
during operation as dust particles
could enter the device.
² It is imperative that you avoid
contamination of the inside of the
front screen, e.g. with fingerprints.
² Do not use any additional sealant for
sealing the front screen, e.g. silicon,
as the vapors produced may
damage the optics.
² Mount the front screen as per the
following instructions to ensure that
the housing is sealed to IP65.
Recommendation If necessary smear a thin coating of vaseline in
the seal groove. This makes mounting easier.
