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 IEC 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 external expansion modules or contactors are used to expand the system's
switching capacity, check the contacts of these devices are forcibly guided. Also use
an NC contact on each device to detect, through a feedback circuit, its correct opera-
tion (see examples) in particular to detect if any contacts are sticking.
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 de-
vice 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 op-
eration 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 (A20). 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 (20 = 2020, 21 = 2021, etc.).
