EZ-SCREEN Point
Instruction Manual
Periodic Checkout Procedures
13. Remove electrical power to the EZ-SCREEN System. All
OSSD outputs should immediately turn OFF, and should
not be capable of turning ON until power is re-applied and,
if in Latch Output mode, a manual reset is performed (Trip
Output mode requires no manual reset).
14. Test the machine stopping response time, using an
instrument designed for that purpose, to verify that it
is the same or less than the overall system response
time specified by the machine manufacturer . (Banner’s
Applications Engineering Department can recommend a
suitable instrument.)
Do not continue operation until the entire checkout
procedure is complete and all problems are corrected.
WARNING . . .
Do Not Use Machine
Until System Is Working Properly
If all of these checks cannot be verified, do not
attempt to use the EZ-SCREEN System/guarded machine until
the defect or problem has been corrected (see Section 5).
Attempts to use the guarded machine under such conditions
could result in serious bodily injury or death.
WARNING . . .
Before Applying
Power to the Machine
Verify that the guarded area is clear of personnel
and unwanted materials (such as tools) before applying power
to the guarded machine.
Failure to do so could result in serious bodily injury or death.
6.4 Daily Checkout
Perform this checkout procedure at every shift change,
power-up and machine set-up change. During continuous
machine run periods, this checkout must be performed
at intervals not to exceed 24 hours. A Designated Person
or Qualified Person (as defined in the Safety Glossary) must
perform the procedure; checkout results should be recorded
and kept on or near the guarded machine, per OSHA
1910.217(e)(1).
1 . Verify that access to the guarded area is not possible from
any area not protected by the EZ-SCREEN System. Hard
guarding, or supplemental presence-sensing devices must
be installed, wherever needed, to prevent any person from
reaching around the light grid or entering into the hazard
area. Verify that all supplemental guarding devices and hard
guarding are in place and operating properly .
2 . Verify that the minimum separation distance from the closest
danger point of the guarded machine to the beam is not less
than the separation distance calculated in Section 3 .3 .1 and
recorded here: ____________ .
3. Verify that it is not possible for a person to stand within the
guarded area, undetected by the EZ-SCREEN System or
by other supplemental guarding (as described in ANSI/RIA
R15.06, or other appropriate standards).
4. Verify that the Reset switch is mounted outside the guarded
area, out of reach of anyone inside the guarded area, and
that the key or other means of preventing inadvertent use is
in place .
5. Test the effectiveness of the EZ-SCREEN System with
power ON, using the trip test (Section 6.2).
6. Initiate machine motion of the guarded machine and, while it
is moving, use the supplied test piece to block the beam. Do
not attempt to insert the test piece into the dangerous parts
of the machine. Upon blocking the beam, the dangerous
parts of the machine should come to a stop with no apparent
delay. Upon removal of the test piece from the beam, verify
that the machine does not automatically restart, and
that the initiation devices must be engaged to restart the
machine .
7. With the guarded machine at rest, block the beam and verify
that it is not possible for the guarded machine to be put into
motion while the test piece is blocking the beam.
8. Check carefully for external signs of damage or changes to
the EZ-SCREEN System, the guarded machine, and their
electrical wiring. Any damage or changes found should be
immediately reported to management .
