Connection of multiple sensors to the safety module
Connection of multiple sensors to one safety module is technically feasible; by con-
necting the corresponding NC contacts for each sensor in series. The control sys-
tem can achieve a maximum of category 3 in accordance with EN ISO 13849-1.
Adhere to the maximum input resistances indicated in the specifications of the
safety modules.
Attention: the series connection of two or more coded sensors reduces the
self-monitoring capacity of the system, see ISO/TR 24119.
5 OPERATION
The safety sensor with coded magnet is used in safety circuits (EN 60204) as an
electrical interlocking device (EN ISO 14119) associated with a movable guard, and
with the relative safety module with automated monitoring for signals elaboration (EN
60947-5-3). When correctly installed and connected to the safety modules, these
sensors allow control circuits with a safety category of up to SIL 3 in accordance with
EN 62061, up to PL e in accordance with EN ISO 13849-1, and up to category 4 in
accordance with EN ISO 13849-1, to be implemented.
5.1 Actuation distances
When the actuator is brought inside the safe activation zone (dark grey area), the
sensor contacts are in the base closed door position.
When the actuator is brought outside the assured release area (light grey area), the
sensor contacts are in the open door position.
Attention: Installing the sensor and coded magnet on ferromagnetic material
reduces the switching distances. The working actuation and release distances must
always be checked following installation.

6 INSTRUCTIONS FOR PROPER USE
6.1 Installation
- Do not stress the device with bending and torsion.
- Do not modify the device for any reason.
- Do not exceed the tightening torques specified in the present manual.
- Observe the assured operating (S
ao
) and release (S
ar
) distances.
- Do not mount the sensor and actuator in strong magnetic fields.
- The device carries out an operator protection function. Any inadequate installation
or tampering can cause serious injuries and even death, property damage, and
economic losses.
- 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, the device may not provide the operator with efficient protection.
- The safety category of the system (according to EN ISO 13849-1), including the safety
device, also depends on the external components connected to it and their type.
- Before installation, make sure the device is not damaged in any part.
- 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 drill the device.
- Avoid any impact with the sensor. Excessive shock and vibrations may affect the
correct operation of the sensor.
- The actuator must not strike the sensor.
- In case of damages or wear, the entire device – including the actuator – must be
replaced.
- 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 fitting surface of the device 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
SUPPORT).
- Before commissioning the machine, and periodically, check for correct switching of
the outputs and correct operation of the system comprising the device and associa-
ted safety circuit.
- In proximity of the device 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. Where welding operations
are to be carried out in the proximity of a previously installed device, it must first be
moved away from the work area. If the sensor is not physically close to the welding
point, the negative pole of the welding current must be as close as possible to the
welding location.
- No work that can cause high-intensity electrostatic discharges (e.g. stripping or rub-
bing plastic surfaces or other materials that can be electrostatically charged) may
be carried out in the vicinity of devices that are supplied with electrical energy, even
if they are switched off or not wired.
- 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.
6.2 Do not use in the following environments
- In environments where the application causes collisions, impacts or strong vibrations to
the device
- In environments containing explosive or inflammable gases or dusts.
- In environments where ice can form on the device.
- In environments containing strongly aggressive chemicals, where the products used co-
ming into contact with the device may impair its physical or functional integrity.
- Prior to installation, the installer must always ensure that the device is suitable for use under
the ambient conditions on site.
