PICO-GUARD Controller
Instruction Manual
Generally, use of the Banner PICO-GUARD System is not
allowed:
• On machinery that has inadequate or inconsistent machine
response time and stopping performance, or
• On machinery with long or excessive stopping times without
a guard-locking mechanism, or
• To guard any machine that ejects materials or component
parts in such a manner that the material or component parts
are not contained and are considered to be a hazard, or
• In any environment that is likely to adversely affect
photoelectric sensing system efficiency. For example,
corrosive chemicals or fluids or unusually severe levels of
smoke or dust, if not controlled, may degrade the efficiency
or effectiveness of the safeguarding function.
The PICO-GUARD Controller and any electrically based
device(s) connected to the PICO-GUARD controller must be
mounted and used outside of the potentially explosive area
or within appropriate explosion-proof enclosures. Approvals
are pending. See www.bannerengineering.com for further
information.
System Overview
The optical elements (such as fiber optic safety interlock
switches, points or grids) are available in a variety of
configurations to allow easy installation and proper operation
on a variety of doors and other hard guarding applications.
Each optical element can be used as either an emitter or a
receiver; they have no electrical connection. This can greatly
reduce the required inventory and simplifies installation.
Plastic fibers are available in three versions: solid-core fiber,
solid-core fiber with integral fluoropolymer sheathing and solid-
core fiber with integral PVC sheathing (see Section 2.2).
Removable terminals simplify the wiring process. See Sections
3.4, 3.7, and 3.9 for electrical connection instructions.
1.2 Applications and Limitations
The Banner PICO-GUARD fiber optic safety system is intended
to be used in a variety of safeguarding applications.
For appropriate applications and complete installation
information, please refer to the bullet items below, individual
sections contained within this manual, the PICO-GUARD
Application and Design Guide, the PICO-GUARD optical
element data sheets, and manuals regarding any external
safeguarding device interfaced with the PICO-GUARD system.
The user must determine whether the use of a particular
safeguard or the Banner PICO-GUARD fiber optic safety system
is allowed.
Appropriate Applications
The PICO-GUARD system is typically used in access-guarding,
perimeter-guarding or interlock barrier guarding applications for
the following types of machines:
• Assembly stations
• Manufacturing cells
• Automated production equipment
• Robotic work cells
