Instruction Manual
Checkout Procedures
9. Observe the Status indicators and the Diagnostic Display:
• Lockout: Status flashing Red
All others OFF
• Blocked: Status ON Red
One or more Zone indicators ON Red
Reset ON Yellow
• Clear: Status ON Green*
All Zone indicators ON Green
Reset ON Yellow
• Latch: Status ON Red
(defined All Zone indicators ON Green
area clear) Reset flashing Yellow
* The Green Status indicator will be flashing if Reduced Resolution is enabled.
10. A Blocked condition indicates that one or more of the beams
is misaligned or interrupted. To correct this situation see the
Alignment procedure in Section 3.4. If the system is in a
Latch condition, perform a manual reset.
11. Once the Green and Yellow Status indicators are ON,
perform the trip test (described in Section 3.4.4) 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 System passes the trip
test. Do not expose any individual to any hazard during
the following checks.
12. Apply power to the guarded machine and verify that the
machine does not start up. Interrupt (block) the defined area
with the appropriate supplied test piece (see table in Section
3.4.4) and verify that it is not possible for the guarded
machine to be put into motion while the beam(s) is blocked.
13. Initiate machine motion of the guarded machine and, while
it is moving, use the supplied test piece to block the defined
area. Do not attempt to insert the test piece into the
dangerous parts of the machine. Upon blocking any beam,
the dangerous parts of the machine should come to a stop
with no apparent delay.
Remove 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.
14. Remove electrical power to the EZ-SCREEN. Both OSSD
outputs should immediately turn OFF, and the machine
should not be capable of starting until power is re-applied to
the EZ-SCREEN.
6.3 Shift/Daily Checkout
Perform the procedure contained on the Daily Checkout card
at every shift change, power-up and machine set-up change.
During continuous machine run periods, this checkout
should 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. A copy of checkout
results should be recorded and kept in the appropriate place
(e.g., near or on the machine, in the machine’s technical file).
Refer to the procedure detailed on the Daily Checkout card
(Banner part number 113361 for SLS.. models, P/N 118173 for
SLSC.. models) in the lit packet included with the receiver. If the
Daily Checkout card is missing, contact Banner Engineering or
download at www.bannerengineering.com .
6.4 Semi-Annual (Six-Month) Checkout
Perform the procedure contained on the Semi-Annual
Checkout card every six months following System
installation, or whenever changes are made to the System
(either a new configuration of the EZ-SCREEN or changes to
the machine).
A Qualified Person (as defined in the Safety Glossary) must
perform the procedure. A copy of checkout results should be
recorded and kept in the appropriate place (e.g., near or on the
machine, in the machine’s technical file).
Refer to the procedure contained on the Semi-Annual
Checkout card (Banner part number 113362) in the lit packet
included with the receiver. If the Semi-Annual Checkout card
is missing, contact Banner Engineering or download at www.
bannerengineering.com .
15. 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 any of these checks cannot be verified, do not attempt to use
the EZ-SCREEN/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.
