MISUSE OF DOCUMENTATION
FF-SPS4 Series
®
NRTL/C
The FF-SPS4 Active Optoelectronic Protective Device is a single through scan infra-
red beam designed to detect the body of an operator on approach to a dangerous
zone.
The interruption of the beam de-energizes the output contacts which in turn de-
energizes the machine stop circuitry.
The emission source is modulated infrared which makes the operation almost com-
pletely independent of ambient light conditions. Moreover, the device is equipped
with an emission frequency selector to avoid possible mutual interference between
sets.
The processing is a permanent dynamic self-checking principle meeting the require-
ments of the norm IEC/EN 61496 - parts 1 & 2 for Type 4 Electrosensitive Protective
Equipment. Any internal failure will be immediately detected and disable the output
relays.
The Canadian CSA (NRTL/C) gave an approval to this device which meets applicable
parts of US ANSI, RIA 15.06 standards and OSHA 29 CFR and 1910.212 regulations
for Control Reliability.
The FF-SPS4 is preset with the start and restart interlock mode on delivery. The start
and restart interlock guarantees that the equipment remains in alarm at power up or
after an interruption of the beam. The operator must press a push-button to restart
the protective equipment. However, an automatic restart can be easily programmed
by internal switches.

FF-SPS4
The receiver unit is equipped with 2 safety relays with guided
contacts which can be directly used to stop the dangerous
movement. However, most of the time, additional relaying (or
Final Switching Devices) between the equipment outputs and
the machine circuitry is necessary. For this reason, the FF-SPS4
has a Final Switching Device monitoring input to negate the use
of a self-checking relay module. A test input is also available.
The use of the test input sets the equipment in an alarm
condition. When used in conjunction with the monitoring
input, the test input facility provides the ability to regularly
check the correct operation of interface relays.
A lens heating system is available on some models to prevent
condensation where conditions of use may require such an
equipment. These models can operate down to -25°C/-13°F
ambient temperature.
LED indicators provide useful visual information on the equip-
ment status during installation and operation. They ease beam
adjustment and warn the operator about a lens contamination
or misalignment before an unexpected emergency stop signal
is generated.
The equipment is delivered with a pair of standard adjustable
brackets for ease of installation. The use of deflection mirrors is
a cost effective solution for designing multiple separate beam
trip devices or perimetric protections around a dangerous area.
A laser pen is available as an accessory. It helps a single person
adjust rapidly and easily the infrared beams even if deflection
mirrors are used.
The device features the highest level of safety and can be used
for a wide range of dangerous machines.

S
The number of beams to be used needs to be defined according
to the risk assessment and to the importance for the machine
operator to pass undetected. Particularly, during risk assess-
ment, methods of defeating the safety equipment shall be taken
into account before selecting the correct configuration.
Protection against mutual interference
When more than one FF-SPS4 is used, mutual interference may
occur between sets.
To avoid these undesirable disturbances, the device is equipped
with internal switches designed to select the emission fre-
quency F1 or F2 of the infrared modulated light. The position of
these switches can be changed to avoid mutual interference
between two systems.
In some cases, mutual interference can be cancelled by using
two different emission frequencies and by reversing the trans-
mission direction of the through scan beams. This would be the
case for a three beam trip device for instance:
Multiple separate beams
Multiple separate beams are often used to detect the intrusion
of the whole body rather than parts of the body.
The installation of a multiple separate beam arrangement has to
be carried out in such a way that access to the dangerous mov-
ing parts is impossible without breaking the beams.
The pr EN 999
European standard gives the following formula
for the calculation of the minimum safety distance between the
dangerous zone and the detection plane. Compliance to this
formula will ensure reliable detection of an operator and stop
the dangerous motion before the operator reaches the danger:

Laser alignment procedure
The use of the FF-SPZLASER pen is recommended to perform
easy and fast beam alignment, particularly if the scanning dis-
tance is greater than 10 m / 32.8 ft. The FF-SPS4 equipment
housing is designed to support the laser pen without any addi-
tional mechanical adapter. A location notch found on the top of
the housing is designed to support the laser pen which should
be used in conjunction with a target (such as a white sheet of
paper) as shown below. However, in the absence of the laser
pen, the notch can be used as a “backsight notch” to ease align-
ment operations.

The position of the emission frequency switches must be changed on both the emitter and the receiver units otherwise the system
remains permanently in alarm.
It is recommended to use the start and restart interlock facility when using the equipment as a trip device to control access to a
dangerous zone. The restart push-button should be installed outside the dangerous zone. However, if the application does not
require this facility, it can be removed using the following indications:
