Attention: The safety circuit must be connected to the NC contacts. The NO
auxiliary contacts can be used for signalling functions.
4.6 Adjustment of the switching point
Adjustment of the switching point can be carried out using a flat-head screwdriver ,
used on the screw that can be reached via the hole on the hinge axis.
The switches are supplied with the adjusting screw unregistered. It is therefore the
responsibility of the installer to adjust the switching point correctly.
Rotating the adjusting screw clockwise reduces the switching point; rotating the screw
counterclockwise increases the switching point. The switching point of the contacts
indicated in the travel diagrams can be adjusted from -0° to +4°.
The maximum torque that can be applied to the adjusting screw is 0.2 Nm.

4.7 Checking the switching point
Attention: Once adjustment is complete, check that
the switching point of the switch is set so that no open-
ings are large enough to allow upper or lower limbs, or
other body parts, to be inserted and reach dangerous
machine parts before they are stopped, or have other-
wise entered a safe state.
The dimensions of the openings on the guards, and the
relative distances from the dangerous points requiring
protection, must comply with the provisions of EN ISO
13857: check the switching point and, if necessary,
repeat the adjustment (see paragraph ADJUSTMENT
OF THE SWITCHING POINT).
4.8 Sealing the adjustment hole of the switching point
always seal the hole with the appropriate protection
cap supplied with the device. Failing to insert the cap
can allow dusts and liquids to penetrate the electrical
contacts, and impair device function.

5 OPERATION
Once the hinge switch is installed to the machine and opening guard, and electrically
connected (as described in paragraph "INSTALLATION INSTRUCTIONS"), opening
the guard must initiate a stop of the machine and related dangerous moving elements.
It must be possible to subsequently restart the machine, only once the guard is closed.

6 INSTRUCTIONS FOR PROPER USE
180°
6.1 Installation
180°
- Do not stress the device with unintended, or greater than intended, bending and
180°
torsion.
- Do not modify the device for any reason.
180°
- Do not exceed the tightening torques specified in the present manual.
180°
- The device carries out an operator protection function. Any inadequate installation or
180°
tampering can cause serious injuries and even death, property damage, and eco-
180°
nomic losses.
- These devices must not be bypassed, removed, turned or disabled in any other way.
180°
- If the machine where the device is installed is used for a purpose other than that
180°
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 sa-
fety 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.
- 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.
- Do not apply excessive force to the device once it has reached the end of its actua-
tion travel.
- Do not exceed the maximum actuation travel.
- 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).
- 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 continual changes in temperature cause the formation of
condensation inside the device.
- 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
coming into contact with the device may impair its physical or functional integrity.
- Prior to installation, the installer must ensure that the device is suitable for use under
the ambient conditions on site.

Rear profile drilling
Create 4 holes with a Ø 8.5 mm diameter
at the distances shown in the drawing.
Always affix the additional hinge with 4 M5 screws with
resistance class 8.8 or higher, and flat seating heads.
Install screws with medium resistance thread locker.
The device must never be fixed with less than 4 screws.
Attention: Affix the device using 4 M5 screws, of
6+T mm length, where T is the thickness of the metal
section used in the guard. Longer or shorter lengths
can damage the hinge.
Do not use a hammer for the adjustments, unscrew the
screws and adjust the device manually, then tighten it
