4.8 Programming rules (ST D•4•••• and ST D•8•••• versions only)
The programmable version is equipped with a dedicated input to enable programming of the sensor
so that it recognises the code contained in a new actuator. This operation is repeatable an unlimited
number of times. After programming has been completed, the sensor will recognise only the actuator
code corresponding to the last executed programming operation.
Attention: The machine manufacturer must allow access to the sensor programming mode
only for suitably trained individuals.
•
Observe all the general warning points.
•
Observe the warnings given in the section INSTALLATION AND CONNECTION INSTRUCTIONS.
•
Once the operation is carried out, check recognition of the newly programmed actuator and the
sensor operation.
4.9 Programming procedure
•
Power the sensor at the rated voltage. The sensor carries out internal tests (1).
•
The programming operation can be carried out either with the safety inputs deactivated (2) or with
the safety inputs activated (3).
•
Activate the I3 programming input by applying the voltage U
e1
. The IN LED starts to flash orange
to indicate the wait for the new code to be memorised (4).
•
Position the new actuator on the sensor so that the centring symbols are aligned. When program-
ming is complete the ACT LED emits four green flashes (5).
•
Programming has been completed successfully when the ACT LED goes out (6). Now deactivate
the programming input I3.
•
The sensor restarts automatically and repeats the internal tests (7) in order to be able to switch to
the "RUN" state.

5 INSTRUCTIONS FOR PROPER USE OF THE DEVICE
5.1 Installation
Attention: Installation must be carried out by qualified staff only.
• Power the sensor and the other safety devices connected to it from a single, safely isolated PELV
or SELV source compliant with applicable standards.
• The safety sensor should be powered using a source different from the one used for the equipment.
• Observe the assured operating (
S
ao
) and release (S
ar
) distances.
• Adjustments should be carried out referring to the diagram shown in the actuation distances
section.
• Do not deform or modify the device for any reason.
• Do not exceed the tightening torques specified in the present manual.
• The device carries out an operator protection function. Any inadequate installation or tampering
can cause people serious injuries and even death.
• These devices must not be bypassed, removed, turned or disabled in any other way.
• If the machine where the device is installed is used for a purpose other than that specified by the
producer, the device may not provide the operator with efficient protection.
• Before commissioning the machine, and periodically, check for correct switching of the outputs and
correct operation of the system comprising the device and associated safety circuit.
• The safety category of the system comprising the safety sensor also depends on external devices
and their connection.
• Before installation, make sure the device is not damaged in any part.
• Before installation, ensure that the connection cables are not powered.
• Avoid excessive bending of connection cables in order to prevent any short circuits or power
failures.
• Do not paint or varnish the device.
• Do not use the device as a support or rest for other structures, such as raceways, sliding guides
or similar.
• Before commissioning, make sure that the entire machine or system complies with all applicable
standards and EMC directive requirements.
• The switch fitting surface must always be smooth and clean.
• The documents necessary for a correct installation and maintenance are always available in the
following languages: English, French, German and Italian.
• Should the installer be unable to fully understand the documents, the product must not be installed
and the necessary assistance may be requested (see paragraph 9).
• During and after the installation do not pull the electrical cables connected to the device.
• In proximity of the sensor do not carry out arc welding, plasma welding, or any other process
that may generate electromagnetic fields of intensity higher than the limits prescribed by the
standards, even when the sensor is off.
Should it be necessary to carry out weldings close to a sensor previously installed, it will be
necessary to first remove it.
• Always attach the following instructions to the manual of the machine in which the device is
installed.
• These operating instructions must be kept available for consultation at any time and for the whole
period of use of the device.
5.2 Do not use in the following environments
• Do not use in environments where the application causes the device to be subjected to strong
impacts or vibrations.
• Do not use in environments where explosive or flammable gases are present.
• Do not use in environments where ice can form on the device.
• Do not use in environments containing strongly aggressive chemicals, where the products used
coming into contact with the device may impair its physical or functional integrity.
5.3 Mechanical stop
• The door must always be provided with an independent end-limit mechanical stop at limit of travel.
All this to protect the device from being knocked when the door is slammed hard.
• Do not use the sensor as a mechanical stop for the door according to EN ISO 14119.
5.4 Shock, vibrations and wear
• In case of damages or wear it is necessary to change the whole device.
• Avoid any impact with the device. Excessive shock and vibrations may affect the correct operation
of the device.
• The actuator must not strike the sensor.
