PICO-GUARD™Systems
Overview
Optical Safety Systems
• Non-contact Fiber Optic Safety System is ideal for
guarding dangerous machinery that can stop
immediately after a stop signal is issued.
• Controller has four optical channels and redundant
Output Signal Switching Devices (OSSDs).
• PICO-GUARD Optical Elements – Interlock Switches,
Points and Grids – provide multiple guarding solutions
in one system. They have no electrical connection and
function either as emitters or receivers, depending on
their connection to the controller. This minimizes the
required component inventory and simplifies
installation.
• Optical elements are designed to meet the requirements
for safeguarding in potentially explosive environments1
(controller must be isolated or located outside of the
volatile area).
• Diverse-redundant, self-checking design to achieve
control reliability and meet IEC 61496-1 type 4 and
ISO 13849-1 (EN 954-1) Category 4 requirements
(approvals pending).
• Accessory interface module available for ac or larger
dc loads.
• Optional remote display module available.
Each PICO-GUARD Fiber Optic Safety System requires a
controller, optical fiber and one or more pairs of optical
elements. Controllers include the System manual and
controller mounting hardware.
The PICO-GUARD Fiber Optic Safety System combines
photoelectric and fiber optic technologies to efficiently
solve a variety of safeguarding applications:
• Monitoring machine access doors and gates
• Entry/exit (work cell access) guarding
• Short-range perimeter guarding
• Multiple fiber optic beam solutions for custom guarding
applications
At the heart of the system is the controller: a diverse-
redundant, microcontroller-based photoelectric device
designed specifically for use with plastic fiber optic
cable.* In addition, the system incorporates a number of
optical elements, including plug-on, snap-lock fiber optic
safety interlock switches, fiber optic grid arrays, and
single-point beam devices.
The controller has four separate optical channels. Each
channel produces pulsed optical signals that travel
through the plastic fiber optic cable, through one
or more optical elements, and ultimately back to
the controller. Each of the controller’s receiver
circuits monitors its specific signal to verify that
its channel is in the safe state. If a person blocks
one of the beams in a grid array or opens a door
being monitored by the system, the optical
signal is “blocked” and does not return to the
receiver. The absence of this signal is detected
and the solid-state safety outputs switch to their
off state, which stops or otherwise prevents the
dangerous motion.

• Two Universal Safety Stop Interface (USSI) inputs which can be used to
cascade controllers or monitor other safeguarding devices (with either
Banner OSSDs or relay contact outputs).
• Selectable functions:
- Selectable Auto/Manual Power-up – Determines whether the System will
require a manual reset to proceed to Run mode when power is applied.
- Selectable Trip/Latch Output – Determines whether the System will
require a manual reset to turn on the OSSD outputs after an optical
channel has been blocked.
- External Device Monitoring (EDM) – Allows the System to monitor the
status of external devices, such as MPCEs (One- or Two-Channel
Monitoring, or OFF).
-Optical Channel Controls – Individual optical channels can be switched to
ON or OFF for applications that require fewer than four operating optical
channels. (At least one channel must be set to ON.)
• Two solid-state safety outputs to control 24V dc loads
• Fast 13 millisecond output response time for the optical channels and
7 millisecond output response time for the USSIs
• Removable terminal blocks speed and simplify wiring
• Sleek, compact, robust housing
• Auxiliary, Weak Signal and Fault outputs for non-safety monitoring
• RS-232 status and diagnostic output (diagnostic/system status and excess
gain estimation software included)
• 35 mm DIN-rail mount
• User-friendly status indicators on the controller’s face
Remote Display
This DIN-mountable unit provides an additional readout of the controller’s
status indicators.

PICO-GUARD Fiber Optic Safety Points are single-beam optical elements. They are suitable
for custom beam-spacing applications. They come in 12 mm and 30 mm, IEC IP65 barrel
configurations with integrated, cut-to-length fiber optic cable.
PICO-GUARD Fiber Optic Safety Points and Grids are designed for use in access-guarding
and perimeter-guarding applications. They are designed to detect a torso (rather than a hand
or an arm) as a person enters a hazardous area. In these applications, personnel typically
can pass through the light grid (which disables or stops the hazard), and then may continue
into the hazardous area after the hazard has been stopped.
Fiber Optic Safety Grids*
The PICO-GUARD Fiber Optic Safety Grids have 2, 3, or 4
beams in an IEC IP65 aluminum enclosure. They connect
to the controller via fiber optic cable and are designed to
meet ANSI/RIA R15.06, ANSI B11 and ISO 13855 (EN 999)
standards for proper beam placement in pass-through
guarding applications.
