WARNING:
Do not use the system until the checkouts are verified
Attempts to use the guarded/controlled machine before these checks are verified could result in
serious injury or death.
If all these checks cannot be verified, do not attempt to use the safety system that includes
the Banner Engineering Corp. device and the guarded/controlled machine until the defect or prob-
lem has been corrected.
Perform this checkout procedure as part of the System installation after the System has been interfaced to the guarded ma-
chine, or whenever changes are made to the System (either a new configuration of the
EZ-SCREEN SLS or changes to the
machine). A Qualified Person must perform the procedure. Checkout results should be recorded and kept on or near the
guarded machine as required by applicable standards.
To prepare the System for this checkout:

7.2
Examine the guarded machine to verify that it is of a type and design compatible with the EZ-SCREEN SLS System.
See " Appropriate Applications and Limitations " on page 11 for a list of appropriate and inappropriate applications.
1.
Verify that the EZ-SCREEN SLS is configured for the intended application.
2.
Verify that the safety distance (minimum distance) from the closest danger point of the guarded machine to the de-
fined area is not less than the calculated distance, per
"Calculating the Safety Distance (Minimum Distance)" on page
22 .
3.

Verify that:
Access to any dangerous parts of the guarded machine is not possible from any direction not protected by
the EZ-SCREEN SLS System, hard (fixed) 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 (fixed) 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 SLS .
4.
If used, 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.
5.
Examine the electrical wiring connections between the EZ-SCREEN SLS OSSD outputs and the guarded machine’s
control elements to verify that the wiring meets the requirements stated in " Electrical Connections to the Guarded Ma-
chine " on page 42 .
6.
Inspect the area near the defined area (including work pieces and the guarded machine) for reflective surfaces
(see " Adjacent Reflective Surfaces " on page 28 ). Remove the reflective surfaces if possible by relocating them,
painting, masking or roughening them. Remaining problem reflections will become apparent during the Trip Test.
7.
Verify that power to the guarded machine is Off. Remove all obstructions from the defined area. Apply power to
the EZ-SCREEN SLS System. If the EZ-SCREEN SLS is configured for Manual Power-Up, the amber Status indica-
tor will be double-flashing. Perform a manual reset (close the reset switch for 0.25 to 2 seconds, then open the
switch).

Observe the Status indicators and Diagnostic Display:
Lockout: Status flashing red; all others Off
Blocked: Status On red; one or more Zone indicators On red; Reset On amber
Clear: Status On green
(1)
; all Zone indicators On green; Reset On amber
Latch: (defined area clear) Status On red; all Zone indicators On green; Reset double-flashing amber
9.
A Blocked condition indicates that one or more of the beams is misaligned or interrupted. To correct this situation,
see "Optically Align the SLS Components" on page 37 . If the System is in a Latch condition, perform a manual reset.
10.
After the green and amber Status indicators are On, perform the trip test ( "Perform a Trip Test" on page 40 ) on each
sensing field to verify proper System operation and to detect possible optical short circuits or reflection problems. Do
not continue until the EZ-SCREEN SLS passes the trip test. Do not expose any individual to any hazard during the
following checks.
