CAUTIONCAUTION
Ulisse UPC photocell meets the requirements of a type 2 safety device only if
connected with a certified safety interface in accordance with the Machine
Directive (89/392 IEC and amendments) and with the standard IEC 1496-1, 2.
ReeR SpA will not be liable for any consequence arising from the use of Ulisse
UPC photocells under conditions differing from the ones described above.
FEATURESFEATURES
• Through-beam barrier type photocell
• Robust and compact metal housing with flat glass lenses. Ulisse is therefore vibration-
resistant, as well as easy to clean and immune to the electrostatic attraction of dust. This
makes it particularly suitable for the use in the textile industry environment. textile industry environment.
• Power supply lines protected towards reverse polarity connections.
• PNP type switching output protected towards short-circuit.
• No false triggering on power-up.
• Test input, which allows the sensor to be tested by a remote controller
• Suitable for risk applications according to IEC 1496 (see par. "Use as a part of a(see par. "Use as a part of a
safety system").safety system").
• Led indicators on both emitter and receiver.
• Complies with 336/89/EC ("EMC Directive") and 23/73/EC ("Low voltage directive").
• Miniature M8 connector.
Ulisse is also available in the UNC version which, in connection with
the control units REER AUS3 or AU S-TWIN, can form a type two,
through-beam, single or double-beam safety light barrier.

OPERATIONOPERATION
When the optical path of the infrared beam linking the emitter with the receiver is totally
interrupted the receiver output switches off and remains in the off-state.
When the beam is released again, the output switches to the on-state.
The correct operation of the photocell is checked by means of the test function, which
permits the measurement the response time: if a low level signal is applied to the emitter's
test input the beam emission is interrupted and therefore the receiver goes to the off-state
within a time approximately equal to 8 msec in a normal operating condition.
USE AS A PART OF A SAFETY SYSTEMUSE AS A PART OF A SAFETY SYSTEM
Ulisse UPC has been third-party certified as being in compliance with the requirements of
IEC 1496 which are relevant for a photoelectric sensor (see enclosed certificate).
Thanks to the test input on the emitter assembly the Ulisse UPC photocells can be connected
with safety devices (e.g. safety-related parts of control systems) measuring their response
time.
Ulisse UPC can therefore be used as a single beam photoelectric detector within a Type 2
safety system for the protection of human beings exposed to hazardous machines or areas ifif
the overall safety system has been certified as being in compliance with the safetythe overall safety system has been certified as being in compliance with the safety
requirements of the "Machine" Directive (89/392/EEC and amendments) or of arequirements of the "Machine" Directive (89/392/EEC and amendments) or of a

No other use of Ulisse UPC as a safety device is admitted. REER will not be liable for any
consequence arising from the use of Ulisse photocells under conditions differing from the
ones described above.

INSTALLATIONINSTALLATION
Preacautions and mechanical installation
Before installation please consider that:
• Neither the emitter nor the receiver have to be placed in the proximity of high-intensity or
blinking light sources
• If the system is installed in places undergoing sudden temperature variations it is
necessary to adopt the customary measures to prevent the formation of condensate on
the lenses, as this might impair their detection capability.
The emitter and the receiver must be installed one in front of the other at a distance which
must not exceed the operating range.
F
A good alignment between the emitter and the receiver is necessary for theA good alignment between the emitter and the receiver is necessary for the
correct operation of the photocell. The green led on the receiver, indicating acorrect operation of the photocell. The green led on the receiver, indicating a
sufficient intensity of the received signal, can help for this purpose.sufficient intensity of the received signal, can help for this purpose.
Distance from reflecting surfaces
Reflecting surfaces located next to the photocell(s) may cause spurious reflections that would
close the optical path between the emitter and the receiver and inhibit the system's detection
capability (fig. 2).
Having completed the installation, check for the presence of reflecting surfaces which might
intercept the beam, first in the centre and then in the proximity of the emitter and the
receiver. If any object is intercepted, the green led located on the receiver (fig. 1) must never
light up.

Multiple systems.
When using 2 pairs of ULISSE UPC photocells arranged next to or on top of each other in
order to prevent them from mutually interfering it is necessary to arrange the elements so
that the beam emitted by one system is received only by the respective receiver (fig. 3).
Figure Figure 33
Safety distance and positioning
The photocell must be installed at a distance greater than or equal to the minimum safety
distance, S, so that no hazardous point can be reached until the hazardous action of the
machine has stopped (fig. 4).
Figure Figure 44
With reference to the proposed European standard prEN999, the minimum safety distance,
S, must be calculated through the following formula:
S = Kt + C
where:
SS is the minimum safety distance expressed in mm.
KK is the speed of approach of the body to the hazardous zone in mm/sec.
tt is the overall system reaction time, including the reaction time of Ulisse single or double
beam, the reaction time of the safety interface and the stopping time of the machine.

ELECTRICAL CONNECTIONSELECTRICAL CONNECTIONS
Ulisse UPC is fitted with a 3 pin M8 male connector (fig. 5).
It is possible to use 5 m or 15 m cables equipped with an M8 female connector, either
straight or at 90°, which can be supplied upon request.

• Before making the connections, make sure that the mains voltage value corresponds
with the one indicated in the technical data.
• Use a PELV type 24 Vdc ± 20% power supply (e.g. through an insulating transformer
complying with EN 60742).

• The line powering Ulisse should be kept separate from the lines powering the other
electrically operated devices (electrical motors, inverters, frequency variators) and the
other possible sources of noise.

respect to the power cables.

CHECKS AND MAINTENANCECHECKS AND MAINTENANCE
The ULISSE UPC photocell has no specific maintenance requirement; at all events, we
recommend cleaning the lenses of the emitter and the receiver at regular intervals, so as to
prevent an excessive quantity of dust from building up and hampering the optical beam
transmission and reception functions, as this may result in the failure of the equipment and
the machine connected to it.
Do not use abrasive or corrosive products, or solvents or alcohol which might damage the
parts to be cleaned.
OPERATING FAULTS.OPERATING FAULTS.
If any operating faults persist even if the system is turned off and on, check the conditions of
the electrical connections.
Furthermore, make sure that the emitter and the receiver are correctly aligned, and the
lenses are perfectly clean. If these measures are not sufficient to restore correct system
operation, send the equipment to our laboratories, complete with all its parts, specifying
clearly:
• part number;
• date of installation;
• hours of operation;
• type of installation;
• fault observed.
