Limits Of Use; Special Conditions - pizzato FD-M2-EX8 Serie Mode D'emploi

- 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.
- The switch fitting surface must always be smooth and clean.
- The documentation required for correct installation and maintenance is available
online in various languages on the Pizzato Elettrica website.
- 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 operating 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.
5.2 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 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.
- In environments where dust and dirt can cover the device and by sedimenting stop
its correct working.
5.3 Mechanical stop
- The device actuator must always be equipped with an independent mechanical stop.
- Do not use the device as a mechanical stop of the actuator.
5.4 Maintenance and functional tests
Attention: Do not disassemble or try to repair the device. In case of any malfun-
ction or failure, replace the entire device.
Attention: In case of damages or wear it is necessary to change the whole de-
vice. Correct operation cannot be guaranteed if the device is deformed or damaged.
- The general maintenance and repair requirements are given in EN 60079-17 and EN
60079-19, respectively. These requirements must be complied with.
- The device installer is responsible for establishing the sequence of functional tests
to which the device is to be subjected before the machine is started up and during
maintenance intervals.
- The sequence of the functional tests can vary depending on the machine complexity
and circuit diagram, therefore the functional test sequence detailed below is to be
considered as minimal and not exhaustive.
- Perform the following sequence of checks before the machine is commissioned and
at least once a year (or after a prolonged shutdown):
1) Switch on the device and verify that the machine behaves as expected.
2) Turn off the device and verify that the machine behaves as expected.
3) Clean the device and avoid the formation of dust layers on the device itself.
4) All external parts must be undamaged.
5) If the device is damaged, replace it completely.
The device has been created for applications in dangerous environments, therefore it
has a limited service life. Although still functioning, after 20 years from the date of ma-
nufacture the device must be replaced completely. The date of manufacture is placed
next to the product code (see paragraph MARKINGS).
5.5 Wiring
Attention: Check that the supply voltage is correct before powering the device.
- Keep the charge within the values specified in the electrical operation categories.
- Do not open the device if voltage is present.
- Always connect the protection fuse (or equivalent device) in series to the NC safety
electrical contacts.
- Adhere to the following minimum and maximum cross-sections of electrical conduc-
tors designed for screw terminals.

5.6 Additional requirements for safety applications with operator protection
functions
Provided that all previous requirements for the devices are fulfilled, for installations
with operator protection function additional requirements must be observed:
1) Utilisation implies knowledge of and compliance with following standards: EN
60947-5-1, EN ISO 13849-1, EN 62061, EN 60204-1, EN ISO 14119, EN ISO 12100.
2) Use only devices marked with the
nect the safety circuit to the NC contacts (normally closed contacts: 11-12, 21-22 or
31-32) as required by EN ISO 14119 paragraph 5.4 for specific interlock applications
and EN ISO 13849-2 table D3 (well-tried components) and D8 (fault exclusions) for
safety applications in general.
