PICO-GUARD Controller
Instruction Manual
Study each procedure in its entirety, to be sure to understand
each step before beginning. Refer all questions to the Banner
Applications Engineering Department at the address or
numbers listed on the front 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
Initial Checkout: The procedure for initial checkout of the
PICO-GUARD System is described in Section 3.8. This
procedure is performed at installation, and at any time the
system, the guarded machine, or any part of the application
is installed or altered. The procedure must be performed by a
Qualified Person (as defined in Section 3.2).
Commissioning Checkout: Should be performed at installation
or whenever changes are made to the system (either a new
configuration of the PICO-GUARD System or changes to the
machine). The procedure must be performed by a Qualified
Person.
Daily Checkout: The procedure for “daily” checkout of the
PICO-GUARD System 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
cards and may be performed by a Designated Person or a
Qualified Person.
Semi-Annual Checkout: The procedure for initial checkout of
the PICO-GUARD System is to be performed every six months,
following installation of the System. The procedure must be
performed by a Qualified Person.
6.2 Trip Test
The procedure for the Trip Test is dependent on the types
of optical element(s) used. Refer to the appropriate Daily
Checkout procedure(s) for Trip Testing the optical element(s)
used in your application.

6.3 Commissioning Checkout
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), or whenever changes are made
to the System (either a new configuration of the PICO-GUARD
System or changes to the machine). 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 12.
