During the warning indication sequences, the remaining grip LEDs remain
illuminated in the base colour configuration set for the specific machine operating
state. During the error indication sequences, the remaining grip LEDs are switched
off: the device does not recover from the error, but must be switched off, and the cause
of the error resolved prior to switching back on.
6 INSTRUCTIONS FOR PROPER USE
6.1 Installation
- Do not stress the device with bending and torsion.
- Do not modify the device for any reason.
- Do not exceed the tightening torques specified in the present operating instructions.
- The device carries out an operator protection function. Any inadequate installation
or tampering can cause serious injuries and even death, property damage, and eco-
nomic losses.
- If the machine where the device is installed is used for a purpose other than that
specified, the device may not provide the operator with efficient protection.
- Before installation, make sure the device is not damaged in any part.
- Avoid excessive bending of connection cables in order to prevent any short circuits
or power failures.
- Do not paint or varnish the device.
- Do not drill the device.
- 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 fitting surface of the device 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).
- No work that can cause high-intensity electrostatic discharges (e.g. stripping or rub-
bing plastic surfaces or other materials that can be electrostatically charged) may be
carried out in the vicinity of devices that are supplied with electrical energy, even if they
are switched off or not wired.
- 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.
6.2 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 containing explosive or inflammable gases or dusts.
- 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.
6.3 Mechanical stop
Attention: The door must always be provided with an independent end-limit
mechanical stop at limit of travel.
Do not use the device as mechanical stop for the door.
6.4 Maintenance and functional tests
Attention: Do not disassemble or try to repair the device. In case of any
malfunction or failure, replace the entire device.
Attention: In case of damages or wear it is necessary to change the whole
device. Correct operation cannot be guaranteed when the device is deformed or
damaged.
- The 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 complex-
ity 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) Check that all the parts that make up the device are fixed together securely.
2) Check that the assembly, made up of metal plate and grip, is fixed securely to the
mobile machine guard.
3) Check that the switch actuator is fixed securely to the metal plate, and centred cor-
rectly in relation to the switch entry hole.
4) Check that the handle grip is fixed securely to the metal plate.
5) Check that the bright signalling LEDs work in all available colour variants.
6) Press the command button on the grip (where present), and check that the machine
behaves as expected.
7) Check that the electrical connecting cable is in good condition, with no cuts or
cracks; in particular where the cable exits the mobile door frame and enters the fixed
machine frame. If the cable is damaged, replace the entire device.
8) All external parts must be undamaged.
9) 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 manufacture the device must be replaced completely. The date of manufacture is
placed next to the product code (see paragraph MARKINGS).
6.5 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.
- Only connect and disconnect the device when the power is off.
- Do not dismount the device for any reason.
- Discharge static electricity before handling the product by touching a metal mass
connected to earth. Any strong electrostatic discharge could damage the device.
- Always connect the protection fuse (or equivalent device) in series with the power
supply for each device.
- During and after the installation do not pull the electrical cables connected to the
device. If traction is applied to the cables, internal parts of the device may be damaged.
- The free end of the cable (if it does not have a connector) must be properly
connected inside a protected housing. The cable must be adequately protected from
cuts, impacts, abrasion, etc.
6.6 Additional prescriptions 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.
- The utilization implies knowledge of and compliance with following standards:
EN 60947-5-3, EN ISO 13849-1, EN 62061, EN 60204-1, EN ISO 14119,
EN ISO 12100.
6.7 Limits of use
- Use the device following the instructions, complying with its operation limits and the
standards in force.
- The devices have specific application limits (min. and max. ambient temperature,
mechanical endurance, IP protection degree, etc.) These limitations are met by the
device only if considered individually and not as combined with each other.
- The manufacturer's liability is to be excluded in the following cases:
1) Use not conforming to the intended purpose;
2) Failure to adhere to these instructions or regulations in force;
3) Fitting operations not carried out by qualified and authorized personnel;
4) Omission of functional tests.
- For the cases listed below, before proceeding with the installation contact our techni-
cal assistance service (see paragraph SUPPORT):
a) in nuclear power stations, trains, airplanes, cars, incinerators, medical devices or
any application where the safety of two or more persons depend on the correct opera-
tion of the device;
b) cases not listed in these operating instructions.
7 MARKINGS
The outside of the device is provided with external marking positioned in a visible
place. Marking includes:
- Producer trademark
- Product code
- Batch number and date of manufacture. Example: A19 AN1-123456. The batch's first
letter refers to the month of manufacture (A=January, B=February, etc.). The second
and third letters refer to the year of manufacture (19 = 2019, 20 = 2020, etc...).
