The BeamSafe II is a long-range, single-beam infrared safety control designed for
perimeter and access guarding. Interruption of the beam sends a stop signal to the
guarded machine. A “redundant” microprocessor design combined with extensive
fault mode and effects analysis 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. Maximum
distance between transmitter and receiver is 200 ft. (60 m).

The system can be set for three possible operating modes:
• Start/Restart Interlock: Upon power-up a start signal (press & release) is
required before system can enter normal operation. If the infrared beam is
obstructed, the output relays will not reset after a beam obstruction is removed
until a start signal has been given to the receiver. This is the mode most often used
for perimeter guarding.
• Start Interlock Mode: Upon power-up a start signal (press & release) is required
before system can enter normal operation. If the infrared beam is obstructed, the
output relays will reset after a beam obstruction is removed, without requiring a
start signal.
• Automatic Restart: Upon power-up the system will enter normal operation. If
the infrared beam is obstructed, the output relays will reset after a beam
obstruction is removed, without requiring a start signal.

The infrared beam from a BeamSafe II transmitter must be set for one of four
possible codes. The beam is coded to avoid cross talk from adjacent units and
improve immunity to weld flash and sources of ambient light.
Both the transmitter and receiver must be set to the same code in order to “talk”
with one another. See installation section for switch setting details.

The Start switch is a normally closed, momentary switch that connects between
the Start and Start Return terminals of the receiver terminal block. A valid Start
signal is a press and release of the switch. The receiver start circuit applies about
5mA DC current through the switch contacts and a pulse of approximately 100mA,
20mS when the switch contacts are initially closed.
In Automatic Start mode a start switch is not required and the terminals can be
left open. In Start Interlock and Start/Restart Interlock modes the start switch is
required to exit Interlock. In all modes, a Start switch can be used to reset an
interlock caused by a fault, once the fault is removed.

Perimeter guarding is a common application for the BeamSafe II and refers to an
installation where a BeamSafe II is generally positioned around the outside
perimeter of a machine or robot to be guarded. This could leave sufficient space
for an operator to stand between the BeamSafe II and the machine.
For perimeter guarding installation, the guarded machine or robot must be wired
such that any detected interruption of the BeamSafe II beam will cause an
immediate stop of the hazardous motion. The machine or robot must only be
restarted by the actuation of a start switch. This start switch must be located
outside the area of hazardous motion and positioned such that the hazardous area
can be observed by the switch operator. This would prevent a machine from
automatically restarting once the obstruction is no longer detected by the
BeamSafe II.
WARNING!
Perimeter guarding installations must not allow a machine or
robot to restart automatically. Use a start switch placed outside and within
view of the hazardous area.

WARNING!
The proper calculation of the safe mounting distance is an
important installation step. Never just install a BeamSafe II at any convenient
location without regard to the safety distance. If the transmitter and receiver
are mounted too close to the point of operation hazard, the machine may not
stop in time to prevent operator injury.
The best information available on safe mounting distance and mounting height
comes from the preliminary European standard prEN999:1994 sections 6.1.4 and
6.1.5.
Section 6.1.5 suggests that single height beams should only be considered where
they are parallel to the ground and the beam is broken by a person’s body in the
upright position.

I NSTALLATION
Minimum Safe Mounting Distance and Mounting
4
BeamSafe II Installation and Operation Manual
Where the risk assessment allows a single height beam to be used alone then the
minimum distance shall be calculated using the following formula:
S = (K x T) + C
Where:
S= the minimum distance from the danger zone to the detection point, line,
plane or zone;
K= a parameter in inches (mm) per second, derived from data on approach speeds
of the body or parts of the body. It is recommended that a minimum value of 63
in/sec (1600mm/sec) be used. Faster speeds may be warranted. To quote from
ANSI standard B11.19-1990, “The value of the hand speed constant, K, has been
determined by various studies and although these studies indicate speed of 63
in/sec. (1600mm/sec) to over 100 in/sec (2450mm/sec), they are not considered
conclusive determinations. The user should consider all factors, including the
physical ability of the operator, when determining the value of K to be used.”
T= the overall system stopping performance. T must include the response time of
controls, clutches, braking systems and the BeamSafe II (35 mS) and the time for
the machine to cease hazardous motion. Add a percentage increase factor as
recommended by the machine manufacturer, to allow for deterioration of the
clutch and braking system.
C= an additional distance in inches (mm), based on intrusion towards the danger
zone prior to the actuation of the protective equipment. In the case of the
BeamSafe II, 48 inches (1200mm)
Example:
S= (63in./sec x 0.250sec) + 48in.
S= 15.75in. + 48in.
S= 63.75in.
When using a single beam, a mounting height of 29 inches (750mm) from the
ground or reference plane has been found in industry to be a practical solution to
the problems of inadvertent access from stepping over or bending under the beam.

WARNING!
All electrical connections must be made by qualified personnel
only and in accordance with local and national electrical codes and
regulations. Shut off all power to the machine and the controller before
connecting. Never allow any metal filings or chips to enter a BeamSafe II
enclosure and possibly impair the function of the BeamSafe II.
Hint: When wiring to BeamSafe II components, leave the wires just long enough
to allow the printed circuit board to be withdrawn to the extent allowed by its
stops. For ease of connection and servicing, OMRON STI recommends the use of 18 AWG
wire when connecting the BeamSafe II to a machine control system.
