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 including its actuator. 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 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) Open the guard while the machine is moving. The machine must stop immediately.
The stopping time of the machine must be always shorter than the time required by the
operator for opening the guard and reaching the dangerous parts.
2) Try to start the machine while the guard is open. The machine must not start.
3) Check correct actuator to device alignment.
4) All external parts must be undamaged.
5) If the device is damaged, replace it completely.
6) The actuator must be securely locked to the door; make sure that none of the
machine operator's tools can be used to disconnect the actuator from the door.
- 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.
In particular, make sure that the supply current does not exceed the values indicated
in the TECHNICAL DATA paragraph; high currents can cause safety device failures or
malfunctions.
The safety device may be used exclusively with resistive loads. The use of inductive
loads can lead to the loss of the safety function.
- 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 open 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.
- Power the safety sensor and the other devices connected to it from a single SELV/
PELV source and in accordance with the applicable standards.
- Always connect the protection fuse (or equivalent device) in series to the safety
electrical contacts.
- During and after the installation do not pull the electrical cables connected to the
device.
- For devices with integrated cable, 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 fun-
ctions
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) Applications not contemplated in this instruction manual.
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: A18 SR1-123456. 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 (20 = 2020, 21 = 2021, etc...).
