PICO-GUARD Controller
Instruction Manual
Periodic Checkout Procedures
14) o Block (open) a channel beam and verify that it is not
possible for the guarded machine to be put into motion
while a beam is blocked (open).
15) o If USSI inputs are used, initiate machine motion of the
guarded machine and, while it is moving, generate a USSI
stop signal by actuating a external stop device. Do not
attempt to reach into the dangerous parts of the machine.
When the USSI signal occurs, the dangerous parts of the
machine should come to a stop with no apparent delay.
Clear the USSI stop signal, and verify that the machine
does not automatically restart, and that the initiation
devices must be engaged to restart the machine. Repeat for
all other external stop devices.
16) o Remove electrical power to the PICO-GUARD System. All
OSSD outputs should immediately turn OFF, and should
not be capable of turning ON until power is re-applied
and, if configured for Manual Power-up, a system reset is
performed (Auto Power-up requires no system reset).
17) o 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.
6.4 Daily Checkout Procedure
The procedure for the Daily Checkout is dependent on the
types of optical element(s) used. Refer to the appropriate Daily
Checkout procedure(s) contained on the Daily Checkout cards
included in the controller lit packet, for Trip Testing the optical
element(s) used in your application.
If Daily Checkout cards are missing, copies are available
by contacting Banner Engineering or download at www.
bannerengineering.com.
WARNING . . . Do Not Use Machine Until
System Is Working Properly
If all of these checks cannot be verified, do
not attempt to use the PICO-GUARD 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.
6.5 Semi-Annual Checkout Procedure
To Be Performed Every Six Months Following System
Installation:
Perform this checkout procedure as part of System installation
(after the System has been interfaced to the guarded machine
as described in Section 3.9), and every six months following
the installation of the System. Semi-Annual checkouts must be
performed by a Qualified Person (as defined by OSHA and in the
Safety Glossary of the manual). A copy of the checkout results
should be kept on or near the machine: see OSHA 1910.217(e)(1).
To prepare the System for this checkout, set the System
configuration as it will be during machine operation.
✔ The Qualified Person must:
1) o Examine the guarded machine to verify that it is of a type
and design compatible with the PICO-GUARD System. See
Section 1.2 for a list of misapplications.
2) o Verify that the maximum gap openings or minimum
separation distances meet the calculated amounts per the
PICO-GUARD Application and Design Guide.
3) o Verify that:
• Access to any dangerous parts of the guarded machine
is not possible from any direction not protected by the
PICO-GUARD System, hard guarding, or supplemental
safeguarding, and
• It is not possible for a person to stand inside the
guarded area, or
• Supplemental safeguarding and hard guarding, as
described by the appropriate safety standards, are in
place and functioning properly in any space between the
optical elements and any hazard which is large enough to
allow a person to stand undetected by the PICO-GUARD
System.
4) o Verify that:
• The Reset switch is mounted outside the guarded area,
out of reach of anyone inside the guarded area,
• There are no individuals within the guarded area, or
otherwise exposed to hazards, and
• The means of preventing inadvertent use is in place.
5) o Examine the electrical wiring connections between the
PICO-GUARD System OSSD outputs and the guarded
machine’s control elements to verify that the wiring meets
the requirements stated in Section 3.9.
6) o Inspect the area near the optical elements (including
guard frame pieces, work pieces and the guarded machine)
for reflective surfaces. (Reflective surfaces may cause light
to reflect around an object in a beam, preventing normal
detection of the safeguard and not stopping the machine
motion.) Remove the reflective surfaces as possible by
relocating them, painting, masking or roughening them.
Remaining problem reflections will become apparent
during step 11.
