Quick Instruction Manual Safety Light Curtain OY32
Devices for finger- and handprotection
Safety Information
The following points must be observed for a correct and safe use of the OY32 safety device:
•The stopping system of the machine must be electrically controlled.
•This control system must be able to stop the dangerous movement of the machine within the
total machine stopping time T as per paragraph 1.3.3 of the manual included in the CD supplied
and during all working cycle phases.
•Mounting and connection of the safety light curtain must be carried out by qualified personnel
only, according to the indications included in the special sections (refer to sections 2; 3; 4; 5) and
in respect to the applicable standards.
•The safety light curtain must be securely placed in a particular position so that access to the
dangerous zone is not possible without the interruption of the beams.
•The personnel operating in the dangerous area must be well trained and must have adequate
knowledge of all the operating procedures of the safety light curtain.
•The TEST button must be located outside the protected area because the operator must check
the protected area during all Test operation.
•The RESET/RESTART button must be located outside the protected area because the operator
must check the protected area during all Reset/Restart operations.
•Please carefully read the instructions for the correct functioning before powering the light
curtain.
Precautions to be observed for the choice and installation
Make sure that the protection level assured by the OY32 device (Type 4) is compatible with the real
danger level of the machine to be controlled, according to EN 954-1 and EN 13849-1.
•The outputs (OSSD) of the ESPE must be used as machine stopping devices and not as command
devices. The machine must have its own START command.
•The dimension of the smallest object to be detected must be larger than the resolution level of
the device.
•The ESPE must be installed in a room complying with the technical characteristics indicated in
section 10 “Technical Data” of the manual include in the CD supplied.
•Do not install device near strong and/or flashing light sources or close to similar devices.

•The presence of intense electromagnetic disturbances could jeopardise device functioning. This
condition shall be carefully assessed by seeking the advice of ipf electronic Technical service.
•The operating distance of the device can be reduced in presence of smog, fog or airborne dust.
•A sudden change in environment temperature, with very low minimum peaks, can generate a small
condensation layer on the lenses and so jeopardise functioning.
•Reflecting surfaces near the safety light curtain light beam (above, under or lateral) can cause passive
reflections that can jeopardize functioning.
•The safety device must be installed at a distance which is major or equal to the minimum safety
distance S to ensure that the operator can not reach the dangerous area until the moving dangerous
object has been blocked by the ESPE.
The failure to respect the safety distance reduces or cancels ESPE the protection function.
For more detailed information about calculation of safety distance, please refer to the complete
manual contained in the CD supplied or available for download on the homepage

ALIGNMENT PROCEDURE
The alignment between the emitting and the receiving units is necessary to obtain the correct functioning of
the light curtain.
A good alignment prevents output instability caused by dust or vibrations. The alignment is perfect if the
optical axes of the first and the last emitting unit beams coincide with the optical axes of the corresponding
elements of the receiving unit.
The beam used to synchronise the two units is the first after the connector. SYNC is the optics connected
with this beam and LAST is the optics connected to the last beam after the SYNC unit.
Receiver
Emitter
Signals are clearly identified through symbols allowing immediate reading, independent of bars directions.
A short description of the signalling LEDs is necessary to avoid misunderstandings.
Two yellow LEDs ( LAST, SYNC) on the receiver facilitate the alignment procedure.
Correct alignment procedure
The light curtain alignment can be effected only after having completed the mechanical installation and the
electrical connections. The following procedure has to be followed:
NOTE: The OY32 safety light curtain is equipped with a system which informs the user on the alignment
obtained.
The alignment function can be activated when powering the device, by keeping the normally open
RESET/RESTART contact closed for at least 0.5 seconds.

alignment
AKeep the receiver in a steady position and set the emitter until the yellow LED ( SYNC) is OFF. This
condition shows the alignment of the first synchronisation beam.
BRotate the emitter, pivoting on the lower optics axis, until the yellow LED ( LAST) is off.
NOTE: Ensure, that the green LED ( NORMAL OP) is steady on.
CDelimit the area in which the green LED ( ) is steady through some micro adjustments - for the first
and then fort he second unit - so to have the maximum alignment (4) and then place both units in the
centre of this area.
D Fix the two units firmly using brackets.
•Verify, that the green LED ( ) on the RX unit is ON and beams are not interrupted, then verify,
that the red LED SAFE (BREAK) ( ) on the TX unit turns ON if even one single beam is interrupted
(condition where an object has been detected).
•This verification shall be made with the special cylindrical test piece having a size suitable to the
resolution of the device used (refer section 2.2.6 “Controls after first installation”).

E Switch OFF and ON the device in normal operating mode.
The alignment level is monitored also during device standard operating mode via display (see section 7.2
of the manual include in the CD supplied).
Once the curtain has been aligned and correctly fastened, the display signal is useful both to check the
alignment and show a change in the environmental conditions (occurrence of dust, light disturbance and
so on) via signal level monitoring.
DIAGNOSTICS FUNCTION
The operator can visualise the operating condition of the light curtains thanks to a one-digit display
positioned on both the RX and TX unit. OY32 also has four LEDs on the RX unit and two LEDs on the TX unit.
The figure below shows all signalling LEDs modes: OFF, ON and BLINKING.
The operator can evaluate the main causes of the system stopping or failure using the 7-segment display and
LEDs used to visualise the functions.
