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 external expansion modules or contactors are used to expand the system's switch-
ing 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 operation (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 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
