4.5 Mounting the device
If necessary, before mounting the device, it is possible to adjust the
position of the auxiliary release (if present) and of the outgoing line
in order to turn the device to the most appropriate position for the
specifi c application. Fully remove the 4 fastening screws in order to
rotate the modules by 90°. The connection output module has a
mechanical limit stop that prevents rotation of more than 270°.
Attention: Do not force rotation of the electrical connection
module beyond 270° as this could damage the device.
After correct positioning of the modules, re-tighten the fi xing screws
with a tightening torque between 0.8 and 1.2 Nm and close the
holes with the provided caps in order to prevent the build-up of
grime.
The device may be fi xed on two sides, using the fi xing holes either
on the front or on the side of the housing.
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 2 screws.
The tightening torque of the 2 M5 screws is 3.0 Nm
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 by closing all fastening holes with the suitable protection
caps provided.
4.6 Mounting the actuator to the protective device
Attention: As required by EN ISO 14119, the actuator must be fi xed immovably
to the door frame.
Always fi x the actuator 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
actuator must never be fi xed with less than 4 screws. The
tightening torque of the 4 M5 screws is 3.0 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 poten-
tial 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
± 2.5 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: Always fi x the device with 2 M5
It is advisable to install the device in the top
Attention: Although the device
is designed to facilitate alignment
between the device and actuator,
excessive misalignment could dam-
age the device. Periodically check the
correct alignment between the safety
device and its actuator.
Maximum misalignment permitted
from the hole axis for rigid doors:
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 mech-
anism 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 available 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 correct 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 70 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 escape release button, if necessary use an appro-
priate sliding guide (pipe or socket) when the button and its extensions exceed a
length of 50 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
- Turn the auxiliary release anticlockwise by 180° with the screwdriver.
