Description
The BeamSafe II is a
long-range single-beam safety
control designed for perimeter
and access guarding. “Diverse
redundant” microprocessor
design provides safe, control
reliable operation.
A BeamSafe II system
consists of one transmitter
and one receiver. No interconnecting cables or separate
control enclosure are required.
Mounted on the receiver, four
separate visible indicators
provide instant information on
system clear, blocked or interlocked status as well as signal
strength. Additional diagnostic
indicators on the receiver
provide codes to assist with
troubleshooting. Output options
include redundant solid-state
or force-guided relays located
in the receiver.
Immunity to weld flash and
ambient light are enhanced
by coding the infrared beam.
This feature also eliminates
interference from other BeamSafe II units installed in close
proximity. A tight beam angle
reduces problems associated
with reflective surfaces. The
Beamsafe II’s built-in lens
heater is effective in environments where condensation
may form on the transmitter or
receiver lens.

Safety Standards and Precautions
The BeamSafe II meets applicable OSHA, ANSI and RIA
standards and was designed in accordance with IEC61496, DIN
EN 50100 and EN 954-1.
Only use the BeamSafe II on machinery that stops consistently
and immediately anywhere in its cycle or stroke. Never use a
BeamSafe II on a full-revolution clutched press or machine.
The BeamSafe II is a single optical beam, not a curtain of light.
Therefore it is not designed for use as a point-of-operation device.
If one or more BeamSafe II systems do not protect all access to
the hazardous machine area, the unprotected access must be
guarded by fencing, barriers or other appropriate methods.
The purchaser, installer and employer are responsible for
meeting all appropriate laws, rules and regulations relating to the
proper use, installation, operation and maintenance of this control
and the guarded machine.
