EZ-SCREEN LP
Instruction Manual Checkout Procedures
6. Checkout Procedures
To prepare the System for this checkout:
1. Examine the guarded machine to verify that it is of a type and
design compatible with the EZ-SCREEN LP. See Section 1.2
for a list of misapplications.
2. Verify that the EZ-SCREEN LP is configured for the intended
application (see Section 4.2).
3. Verify that the minimum safety distance from the closest
danger point of the guarded machine to the defined area is
not less than the calculated distance, per Section 3.1.1 of this
manual.
4. Verify that:
• Access to any dangerous parts of the guarded machine
is not possible from any direction not protected by
the EZ-SCREEN LP, hard guarding, or supplemental
safeguarding, and
• It is not possible for a person to stand between the defined
area and the dangerous parts of the machine, or
• Supplemental safeguarding and hard guarding, as described
by the appropriate safety standards, are in place and
functioning properly in any space (between the defined area
and any hazard) which is large enough to allow a person
to stand undetected by the EZ-SCREEN LP (see Sections
3.1.2 and 3.1.4).
5. Verify that all reset switches are mounted outside and in full
view of the guarded area, out of reach of anyone inside the
guarded area, and that means of preventing inadvertent use is
in place (see Section 3.1.3).
6. Examine the electrical wiring connections between the
EZ-SCREEN LP’s FSD outputs and the guarded machine’s
control elements to verify that the wiring meets the
requirements stated in Section 3.5.
7. Inspect the area near the defined area (including work pieces
and the guarded machine) for reflective surfaces (see Section
3.1.6). Remove the reflective surfaces if possible by relocating
them, painting, masking or roughening them. Remaining
problem reflections will become apparent during the trip test
in step 11.
8. Apply power to the EZ-SCREEN LP. Verify that power to the
guarded machine is OFF. Remove all obstructions from the
defined area. If the EZ-SCREEN LP is configured for latch
output, the Yellow Status indicator will double-flash; perform a
manual reset (close the reset switch for 1/4 to 2 seconds, then
open it).
Study each procedure in its entirety, to understand each step
thoroughly before beginning. Refer all questions to a Banner
applications engineer at the address or numbers listed on the
cover of this manual. Checkouts must be performed as detailed
in Section 6.1 below and results should be recorded and kept
in the appropriate place (e.g., near the machine, and/or in a
technical file).
6.1 Schedule of Checkouts
Trip Test: The procedure for the EZ-SCREEN LP trip test is
described in Section 3.4.4. This procedure must be performed
at installation, and at any time the EZ-SCREEN LP, the guarded
machine, or any part of the application is installed or altered.
The procedure must be performed by a Qualified Person.
Commissioning Checkout: The procedure described in Section
6.2 must be performed at installation or whenever changes
are made to the System (either a new configuration of the
EZ-SCREEN LP or changes to the machine). The procedure
must be performed by a Qualified Person.
Shift/Daily Checkout: The procedure for “daily” checkout of the
EZ-SCREEN LP is described on the supplied Daily Checkout
card (Banner p/n 140045 for SLP.. stand-alone models, P/N
140046 for SLPC.. cascadeable models). Daily Checkout is to
be performed at each shift change or machine setup change,
whenever the System is powered up — at least daily. The
procedure is listed on the Daily Checkout card and may be
performed by a Designated Person or a Qualified Person.
Semi-Annual Checkout: The procedure for initial checkout
of the EZ-SCREEN LP System is to be performed every six
months, following installation. The procedure is listed on the
Semi-Annual Checkout card (Banner P/N 140047) and must be
performed by a Qualified Person.
6.2 Commissioning Checkout
Perform this checkout procedure as part of the EZ-SCREEN
LP installation (after it has been interfaced to the guarded
machine as described in Section 3.5), or whenever changes
are made to the System (either a new configuration of the
EZ-SCREEN LP or changes to the machine). A Qualified
Person (as defined in Section 4.1) must perform the procedure;
checkout results should be recorded and kept on or near the
guarded machine as required by applicable standards.
