Quick Instruction Manual Safety Light Curtain OY36
Devices for bodyprotection
Safety Information
The following points must be observed for a correct and safe use of the OY36 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 OY36 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.
The alignment is perfect if the optic axes of the first and the last emitting unit’s beams coincide with the optic
axes of the corresponding elements of the receiving unit. Two yellow LED indicators (HIGH ALIGN, LOW
ALIGN) facilitate the alignment procedure.
Correct alignment procedure
When the mechanical installation and the electrical connections have been effected –as explained inthe
previous paragraphs –it is possible to carry-out the alignment of the safety light curtain, according to the
following procedure:
•Disconnect the power supply to the light curtain.
•Press the TEST/START button and keep it pressed (open the contact).
•Re-connect the power supply.
•Release the TEST/START button.
•Check the green LED on the bottom of the TX unit (POWER ON) and the yellow LED (NORMAL
OPERATION); if they are ON, the unit is running correctly.
•Verify that one of the following conditions is present on the RX unit:
1. Red LED (SAFE) ON: non-alignment condition.
2. Green LED (NORMAL OPERATION) ON: light curtain already aligned condition; in this case also the
two yellow LEDs will be ON (HIGH ALIGN, LOW ALIGN).
•Continue with the following steps to change from condition 1 to condition 2:
A Keep the receiving unit in a steady position and set the transmission unit until the yellow LED on
the bottom (LOW ALIGN) is ON. This condition shows the effective alignment of the first lower
beam.
B Rotate the transmission unit until the upper yellow LED (HIGH ALIGN) is ON; in this condition red
LED (SAFE) must turn off and green LED (NORMAL OPERATION) must turn ON.
Note: ensure that the green LED (NORMAL OPERATION) modo is ON and steady.
C Delimit the area in which the green LED (NORMAL OPERATION) is steady through some micro
adjustments - for the first and then for the second unit - then place both units in the centre of this
area.
•Fix the two units firmly using pins and brackets.
•Disconnect the power supply to the light curtain.
•Re-connect the power supply.
Verify that the green LED is ON on the RX unit (condition where the beams are free, NORMAL OPERATION)
and verify that, if even one single beam is obscured, the green LED turns OFF and the red LED turns ON
(condition where an object has been detected, SAFE).

DIAGNOSTIC FUNCTIONS
Visualisation of the functions
The operator can verify the operating condition of the light curtains through four LEDs positioned on the
receiving unit and two LEDs on the emitting unit.
The LEDs located on the emitter (TX) have the following meanings:
YELLOW LED NORMAL OPERATION: when ON, indicates that the unit is emitting correctly.
GREEN LED POWER ON: when ON, indicates that the unit is correctly powered.
The meaning of the LEDs positioned on the receiving unit (RX) depends on the light curtain operating
mode.
Alignment mode
In this condition the outputs are OFF (SAFE state).
GREEN LED NORMAL OPERATION: when ON, indicates that no objects have been detected by the
device.
RED LED SAFE: when ON, indicates that the receiving and the emitting units are not aligned, or that
an object has been detected.
YELLOW LED HIGH ALIGN: when ON, indicates the correct alignment of the last TX optic with the
corresponding RX optic (top side of the device).
YELLOW LED LOW ALIGN: when ON, indicates the correct alignment of the first TX optic with the
corresponding RX optic (lower side of the device).
Operating mode
GREEN LED NORMAL OPERATION: when ON, indicates that no objects have been detected by the
device.
RED LED SAFE: when ON, indicates that one object has been detected; in this condition the outputs
are OFF.
YELLOW LED HIGH ALIGN: when continuously ON, indicates the INTERLOCK state, so that it is
necessary to press the TEST/START button to reset the device
consequently to an object interception. This occurs only when the
device runs under the manual Reset mode.
