3 DESCRIPTION
3.1 Device description
The safety device described in these operating instructions is defined as a coded,
type-2 mechanical interlocking device with lock acc. to EN ISO 14119.
The safety switches with separate actuator with lock to which these operating
instructions refer are safety devices designed and implemented for the control
of gates, guards, enclosures, and doors in general, which are installed to protect
dangerous parts of machines with or without inertia.
3.2 Intended use of the device
- The device described in these operating instructions is designed to be applied on
industrial machines (as defined in the Machinery Directive) for state monitoring of
movable guards.
- The direct sale of this device to the public is prohibited. Installation and use must be
carried out by qualified personnel only.
- The use of the device for purposes other than those specified in these operating
instructions is prohibited.
- Any use other than as expressly specified in these operating instructions shall be
considered unintended by the manufacturer.
- Also considered unintended use:
a) using the device after having made structural, technical, or electrical modifications
to it;
b) using the product in a field of application other than as described in paragraph
TECHNICAL DATA.

4 INSTALLATION INSTRUCTIONS

Attention: Installing a protective device is not sufficient to ensure operator
safety or compliance with machine safety standards or directives. Before installing a
protective device, perform a specific risk analysis in accordance with the key health
and safety requirements in the Machinery Directive. The manufacturer guarantees
only the safe functioning of the product to which these operating instructions refer, and
not the functional safety of the entire machine or entire plant.
4.1 Selection of the actuator type
Attention: Since the device is activated using an actuator with a low level of
coding, the additional specifications given in Std. EN ISO 14119:2013 paragraph 7.2
must be applied during the installation.
Attention: Any other actuators present in the same place where the device has
been installed must be segregated and kept under strict control in order to avoid any
bypassing of the safety device. If new actuators are fitted, the original actuators must
be disposed of or rendered inoperable.
4.2 Selection of the working principle
Attention: The device is available with two working principles:
1) Working principle D for versions FS ••96D••• and FS ••98D•••: locked actuator with
de-energised solenoid (spring lock, release with activation of inputs A1/A2);
2) Working principle E for versions FS ••96E•••: locked actuator with energised
solenoid (lock with activation of A1/A2 inputs, spring release).
Working principle D (spring lock) maintains the actuator lock even if the machine
is disconnected from the power supply. Therefore if the machine has dangerous
movements with inertia, inaccessibility to dangerous parts (actuator locked) is
ensured, even in the event of a sudden power failure.

Working principle E (lock with activation of A1/A2 inputs) keeps the actuator lock only
when the machine is connected to the power supply. Therefore, before choosing this
working principle, carefully evaluate all dangers deriving from sudden power failure
with a consequent possible immediate actuator release.
The choice between working principles D and E must always be made following a risk
analysis of the specific application.
In case of machines without inertia, i.e. with dangerous elements being
immediately blocked as soon as the guard is opened, for which a device with lock has
been chosen merely to safeguard the production process, the first or the the second
working principle can both be used indifferently.
4.3 Head and release device (where present) orientation
The switch head has two actuator inputs: one perpendicular, and the other parallel
to the device body. Once the actuator input direction has been selected, the unused
input hole must be sealed, using the appropriate cap supplied. It is possible to use one
single hole at a time, with one single actuator.
4.4 Fixing of the device
4.5 Fixing the actuator to the guard
Attention: As required by EN ISO 14119, the actuator must be fixed immovably
to the door frame.
Please make sure to use only the actuator provided with the switch or use one of
the following actuators: VF KEYF, VF KEYF1, VF KEYF2, VF KEYF3, VF KEYF7,
VF KEYF8. The use of any other actuator does not guarantee the safety of the system.
Install the actuator so that its edge does not protrude dangerously into the
operator working area when the door is open.
Always affix the actuator with 2 M5 screws with resistance
class 8.8 or higher, and flat seating heads. Install the screws
with medium resistance thread lock, and a number of
threads engaged equal to or greater than the screw diame-
ter. The actuator must never be fixed with fewer than 2
screws.
The tightening torque of the two M5 screws must be be-
tween 2.0 and 3.0 Nm.
For correct fixing, other means can also be used, such as
rivets, non-removable security screws (one-way), or other
equivalent fixing system, provided that it can ensure ad-
equate fixing.

Before fixing the device, it is possible, if neces-
sary, to adjust the position of the head and the
key release device (if present) in order to turn
the device to the position best suited to the ap-
plication.
Remove the 2 screws on the top of the head,
and disconnect the head from the switch body.
Remove the 4 fixing screws from the auxiliary
release device; rotate it by 90° to the desired po-
sition, and retighten the 4 screws.
Position the switch head above the auxiliary re-
lease device to the desired orientation (by rotat-
ing by 90°) and retighten the 2 fixing screws in
the holes provided.
Attention: Once adjustment is complete,
tighten the head, using the two one-way safety
screws supplied with the device.
Attention: Tighten the head and auxiliary
release device screws to a torque from 0.8 to
1.2 Nm.
Attention: Always affix the device with 2 M5
screws with resistance class 8.8 or higher, flat seating
heads and washers inserted beneath them. Install the
screws with medium resistance thread lock, and a
number of threads engaged equal to or greater than
the screw diameter. The device must never be fixed
with less than 2 screws.
The tightening torque of the two M5 screws must be
between 2.0 and 3.0 Nm.
It is advisable to install the device in the top part
of the door, in order to prevent any dirt or work resi-
dues from getting inside the hole where the actuator
is to be introduced. In order to avoid device bypassing
it is advisable to fix the device body to the machine
frame so that it cannot be removed.
