4.5 Mounting the device
Before mounting the device: if necessary, it is possible to
adjust the position of the head and the auxiliary release (if
present) in order to turn the device to the most appropriate
position for the specifi c application. Fully remove the 4
head screws in order to independently turn either the head
or the auxiliary release over an arc of 270°.
Attention: Do not force rotation beyond 270° as this
could cause damage to the device. Once adjustment is
complete, re-tighten the head screws with a torque between 0.8 and 1.2 Nm.
Once the head of the device is in position, you must use the two safety screws sup-
plied, in place of the two original screws, at opposite corners.
Attention: Always fi x the device with 4 M5 screws with
property class 8.8 or higher, and fl at seating heads. Install the
screws with medium thread lock, and a number of threads
engaged equal to or greater than the screw diameter. The device
must never be fi xed with less than 4 screws. Tighten the 4 M5
screws to a torque from 2 to 3 Nm.
It is advisable to install the device in the top part of the door,
in order to prevent any dirt or work residues from getting inside
the hole where the actuator is to be introduced. In order to avoid
device bypassing, it is advisable to fi x the device housing to the
machine frame so that it cannot be removed.
4.6 Mounting the actuator to the protective device
ator must be fi xed immovably to the door frame.
Always fi x the actuator with 4 M5 screws with prop-
erty class 8.8 or higher, and fl at seating heads. Install
the screws with medium thread lock, and a number of
threads engaged equal to or greater than the screw
diameter. The actuator must never be fi xed with less than
4 screws. Tighten the 4 M5 screws to a torque from 2 to 3 Nm.
After the fi xing operation, it is mandatory to plug the holes of the 4 screws using the
caps supplied. Using the caps is considered a supplementary measure to reduce the
potential of actuator disassembly to a minimum, in accordance with EN ISO 14119.
For correct mounting, other means can also be used, such as rivets, non-removable
one-way security screws or other equivalent mounting systems, as long as they can
ensure adequate mounting.
4.7 Device-actuator alignment
the hole axis for rigid doors: ± 2 mm vertical and horizontal.
The actuator must not hit the outside of the actuator inlet area, and must not be used
as a centering device for the safety door.
In the case of application on swing doors, check that the radius between the axis of the
actuator and the axis of the hinge fi tted on the door is greater than 150 mm.
Do not use a hammer for the adjustments, unscrew the screws and adjust the device
manually, then tighten it in position.
This device is not suitable for applications in which the protective device with the
permanently attached actuator allows misalignments such as the actuator shaft not
entering through the corresponding hole of the device with the door completely closed.
The device is provided with a through hole for inserting the actuator. In the case
where it is used in dusty places, make sure not to obstruct the outlet hole opposite the
inlet hole. This way, any dust which may go inside the hole will always be allowed to
come out of the opposite side.
Attention: As required by EN ISO 14119, the actu-
Attention: Although the device is
designed to facilitate alignment between
the device and actuator, excessive mis-
alignment could damage the device.
Periodically check the correct alignment
between the safety device and its
actuator.
Maximum misalignment permitted from
4.8 Escape release button
Some of the device versions are provided with an escape release button in order to
allow any personnel accidentally trapped inside the machine to get out. This button,
complying with the EN ISO 14119 standard, directly acts on the lock mechanism and
immediately releases the actuator regardless of the operating state of the device.
Pressing this button causes:
- In mode 1: immediate deactivation of the OS1, OS2 safety outputs and of the
O4 signal output;
- In mode 2: immediate deactivation of the O4 signal output only;
- In mode 3: immediate deactivation of the OS1 safety output and of the O4 signal
output.
This escape release button unlocks the protective device even if the device is
not powered on.
For correct installation of the escape release button, the following notes must be
observed.
- The escape release button must be clearly visible from inside
the machine.
- Button activation must be easy, immediate and independent
from the machine operating state; for easier recognition of
the button and explanation of its function, stickers are avail-
able in various languages.
- For an operator standing outside the machine, the escape
release button must not be within immediate reach when the
safety door is closed.
- To guarantee correct operation and safe resetting, a distance
ranging from 10 to 35 mm must be kept between the wall on
which the button is mounted and the escape release button.
- The release button sliding area is to be kept clean. Any
ingress of dirt or chemical substance can compromise device
operation.
- The personnel concerned must be adequately trained on cor-
rect button operation, so as to avoid any improper use (i.e. the button must not
be used as a clothing hook).
- The escape release button must not be used as a machine emergency stop.
For installation on walls thicker than 20 mm, extensions are available for the release
button.
For correct installation of the extensions, the following notes must be observed:
- Do not exceed an overall length of 500 mm between the release button and the
device;
- Always use medium screw locking adhesive on every screw connection between
button, extensions, and safety device;
- Avoid twisting or bending the release button, if necessary use an appropriate
sliding guide (pipe or bush) when the button and its extensions exceed a length
of 100 mm;
- Tightening torque for button and extensions from 4 to 5 Nm.
4.9 Auxiliary release with a tool or lock
Some of the device versions are provided with an auxiliary release in order to allow
easy installation (release with a screwdriver) or to permit opening for authorized
personnel only (lock release). Both these mechanical release devices act inside the
safety device like the escape release button previously described. Therefore they also
unlock the protective device in case of power failure. These auxiliary release may
only be operated by qualifi ed personnel who has received adequate training on the
dangers deriving from their use.
4.9.1 How to use the auxiliary release with a screwdriver
-
Unscrew the locking screw with a PH1 cross-head screwdriver
-
Turn the hexagon socket clockwise by 180°
-
Do not force the hexagon socket beyond 180°
-
To avoid any improper use of the auxiliary release with a tool, it
is advisable to seal the device through the appropriate hole found
in the upper part, or to seal the screw cross head with a few drops
of paint.
-
After each actuation, it is advisable to reseal the device.
