7.3 Maintenance and functional tests
Attention: Do not disassemble or try to repair the device. In case of any malfunc-
tion or failure, replace the entire device.
- 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 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 the safety module housing is undamaged and in good condition. If the
housing is damaged, replace the entire device.
2) Check that all signalling LEDs are working.
3) Check that the electrical cables are firmly lodged inside the terminals and con-
nectors.
4) Check that during operation the module behaves according to the operating dia-
grams provided in section OPERATION.
5) While the motor is running, both NO safety contacts must be open and the NC
auxiliary contact closed.
6) While the motor is at a standstill, both NO safety contacts must be closed and the
NC auxiliary contact open.
- 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).
7.4 Wiring
Attention: Do not install the safety module if voltage is present. Power the device
only when the electrical circuits have been completely realized according to the speci-
fications indicated in the OPERATION paragraph. The first time you start the machine
ensure that there are no people close to hazardous areas.
- 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.
- When using plug-in-type terminal blocks, they may only be plugged in or unplugged
if no supply voltage is present.
- Discharge static electricity before handling the product by touching a metal mass
connected to earth. Any strong electrostatic discharge could damage the device.
- Supply the semiconductor signalling outputs from a single SELV/PELV voltage
source according to applicable standards.
- It is recommended that the supply voltage of the safety module be electrically iso-
lated from the power section of the machine and the connection cables of the module
be laid separately from the power cables.
- Always connect the protection fuse (or equivalent device) in series with the power
supply for each device.
- 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. If excessive tension is applied to the cables, the device may be damaged.
7.5 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 ISO 13849-1, EN 62061, EN 60204-1, EN ISO 12100.
- In the risk analysis, take into account that in manual start mode a possible sticking of
the start button can lead to an immediate activation of the module.
- If expansion modules or external contactors are used, make sure that they have
forcibly guided contacts and connect in feedback an NC contact of each device.
7.6 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,
maximum currents, IP protection degree, etc.) These limitations are met by the device
only if considered individually and not as combined with each other.
- According to EU directives, this device is not intended for private use.
- 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 as-
sistance 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.
8 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: CS1-123456 (A19). The last part
of the production batch refers to the month of manufacture (A = January, B = February,
etc.) as well as the year of manufacture (19 = 2019, 20 = 2020, etc.).
