General Catalogue Safety 2017-2018
Description
These switches are used on machines where the hazardous conditions remain for a while, even after the
machine has been switched off, for example because of mechanical inertia of the pulleys, saw disks, mills. This
switch has its ideal application where the guard is not opened frequently and the installation of a switch with
solenoid would be too expensive.
These switches are considered interlocks with guard locking in accordance with ISO 14119, and the product is
marked on the side with the symbol shown.
6
Head and knobs with variable orientation
The head can be quickly
turned to each of the four
sides of the switch by unfastening the two fastening
screws.
The mechanical delay device
can be rotated in 90° steps
as well. This enables the
switch to assume 32 different configurations.
Protection degree IP67
These devices are designed to be used in the
toughest environmental conditions and they pass
the IP67 immersion test acc. to EN 60529. They
can therefore be used in all environments where maximum protection
degree of the housing is required.
Holding force of the unlocked actuator
The inside of each switch features
a device which holds the actuator
in its closed position. Ideal for all
those applications where several
doors are unlocked simultaneously,
but only one is actually opened. The
device keeps all the unlocked doors
in their position with a retaining
force of 30 N~, stopping any vibrations or gusts of wind from opening
them.
Adjustment range
The actuation head of this switch
0,5 ... 5 mm
features a wide range of travel. In
this way the guard can oscillate
along the direction of insertion
(4.5 mm) without causing unwanted machine shutdowns. This wide
range of travel is available in all
actuators in order to ensure maximum device reliability.
Contact block
Contact blocks with captive screws, finger
protection, twin bridge contacts and double
interruption for higher contact reliability. Available in multiple versions with shifted, simultaneous or overlapping actuation paths. They
are suitable for many different applications.
Extended temperature range
These devices are also available in a special
version suitable for an ambient operating temperature range from -40ºC up to +80°C.
They can therefore be used for applications in cold stores, sterilisers
and other equipment with low temperature environments. The special materials used to produce these versions retain their characteristics even under these conditions, thereby expanding the installation
possibilities.
Laser engraving
All devices are marked using a dedicated
indelible laser system. These engravings
are therefore suitable for extreme environments too. Thanks to this system that
does not use labels, the loss of plate data
is prevented and a greater resistance of
the marking is achieved over time.

Safety screws for actuators
As required by EN ISO 14119, the actuator must
be fixed immovably to the door frame. Pan head
safety screws with one-way fitting are available
for this purpose. With this screw type, the actuators cannot be removed or tampered by using
common tools. See accessories on page 310.

Safety switches with manual mechanical delay and separate actuator
Operation (FP 6R2-M2F1)
The switch is fastened to the machine body (A), while the stainless steel actuator is fastened to the guard (B). Once installed, the switch will
firmly lock the actuator. In order to remove the actuator, the knob (C) has to be rotated. On the first turns the electrical contacts will positively
open, then, after about 20 seconds (or 10 seconds depending on the version), the actuator will be released. In order to close the guard, the knob
must be rotated in the opposite direction. This switch doesn’t need power supply or timer and can be easily installed on old machines without
important changes in their electrical circuit. The knob (C) may be supplied in a short (standard) or in a long version.

applications, actuate the switch at least up to the positive opening travel
shown in the travel diagrams with symbol

Limits of use
Do not use where dust and dirt may penetrate in any way into the head and deposit there. Especially not where powder, shavings, concrete or
chemicals are sprayed. Adhere to the EN ISO 14119 requirements regarding low level of coding for interlocks. Do not use in environments with
presence of explosive or flammable gas. In these case use ATEX products (see dedicated Pizzato catalogue).
Attention! These switches alone are not suitable for applications where operators may physically enter the dangerous area, because an eventual
closing of the door behind them could restart the machine operation. In these cases, the maintenance personnel must use the actuator entry
locking device VF KB1 shown on page 144.
