CAUTION

ULISSE UNC series photocells

WITHOUT THE CONTROL UNITSWITHOUT THE CONTROL UNITS

AU S3, AU S-TWIN or AU S3M2AU S3, AU S-TWIN or AU S3M2

cannot be used as safety devices for the protection of people exposed to
hazardous machines or systems.

Accordingly, REER will not be liable for any consequences arising from the
use of its ULISSE photocells without the relative control units, as this use
does not meet the requirements of EC machine directive 89/392.

WARNINGSWARNINGS

The ULISSE UNC safety system is composed of one or two pairs of photocells connected
either to the standard control unit (AU S3) or to the unit with built-in muting function
(AU S3M2); the system can be composed of one, two, three or four pairs of photocells
connected to the control unit AU S-TWIN.

To understand the operation of these devices we recommend reading a few sections of the
relative installation manuals; in particular:

• Manual code 8540399 - "AU S-TWIN":

– Operating modes
– Configuration of the unit
– Status of contacts
– Indicator lights
– Specifications

• Manual code 8540404 - "ARGOLUX series AS":

– Test function and control unit status
– Start up test
– Operating diagram
– Status of contacts
– Indicators (Control unit)

GENERALGENERAL

ULISSE UNC is a barrier type photocell consisting of a separate emitter and a receiver.
Whether connected to the control units, AU S3, AU S-TWIN, or to the control unit with

built-in muting function, AU S3M2, ULISSE UNC represents a type 2 safety system with one,
two, three or four (AU S-TWIN) beams, suitable for the protection against accidents of
people exposed to hazards on dangerous machinery. The metal container and the glass
lenses make the product extremely sturdy and immune to the electrostatic attraction of dust,
i.e., ideally suited for use in the textile processing plants.

The switching of the output relays of the control unit upon the interception of the beam stops
the movement of machine tools with mechanical moving parts, such as, for instance:

• Looms;

• Assembly lines;

• Automated industrial warehousing systems;

• Robotised areas;

• Handling, palletising/de-palletising systems.

OPERATIONOPERATION

The ULISSE UNC safety system may consist of one two, three or four emitter/receiver pairs
connected to a control unit. This system is able to detect the passage of a person’s entire
body and cannot be used for the protection of arms and hands.

Whenever the optical path of the infrared beam linking the emitter to the receiver is totally
interrupted, the receiver cuts off the output signal. Upon recognising this condition, the
control unit immediately de-energises its outputs thereby preventing the coming into being of
a hazard condition.

When the beam is released, the system restart depends on the positive outcome of the test
function. The test is conducted as follows:

• the control unit turns off the emitter;

• the receiver detects the interruption of the beam and cuts off the output signal;

• the control unit checks the adequacy of the reaction time of the receiver, the outputs of

the latter and the external relays, if any are used.

This test is controlled externally, by pressing a special test button.
