2 Safety
2.1 Intended Use
When used as intended, the AS-Interface safety module allows the operation of sensor-con-
trolled personal protective equipment up to category 4 and PL e as per ISO 13849 or up to SIL
3 as per EN/IEC 61508 and EN/IEC 62061 in combination with an appropriately programmed
AS-Interface safety monitor. The safety level of the application is determined either via a risk
analysis, e.g., in accordance with EN 1050, or is taken from a C standard.
2.2 Peripheral Requirements
Safety Monitor Requirements
The module must only be used as a safety-related slave in an AS-Interface segment with the
corresponding AS-Interface safety monitor as intended. The AS-Interface safety monitor must
meet the requirements of the "Specification of Safe AS-Interface Transmission" system specifi-
cation (version 2.01) dated 05/12/2000.
To evaluate a safety-related function in accordance with a safety standard, all components
found in the function must be evaluated in accordance with this standard.
The wiring and programming of the safety monitor determine whether or not the required safety
function performs correctly. This also applies to the required safety response after a code fault
or failure (see also safety monitor documentation). The safety function (including all safety-
related sensors) must be checked prior to initial commissioning. The safety monitor PL cate-
gory or SIL must, as a minimum, comply with the PL category or SIL required by the applica-
tion.
Cabling Requirements
The requirements set out in EN/IEC 60204-1 or similar must always be observed. The require-
ments for the external cabling and selection of connected sensors are based both on the level
of functionality to be achieved, and on the required category (ISO 13849-1, EN/IEC 61508, or
EN/IEC 62061).
Switches or Mechanical Contacts
The switches must be positive opening. Combinations of switches that provide an equivalent
level of safety (fault behavior analysis) can be used.
2.3 General safety instructions
The module can only be operated by trained professionals in accordance with the available
instruction manual.
Connecting modules and performing maintenance tasks while the devices are connected to a
power source must only be performed by trained electrical specialists.
If malfunctions cannot be eliminated, the module must be taken out of operation and protected
from being inadvertently placed back in operation.
Repairs must only be performed directly by the manufacturer.
Making changes to or tampering with the device is not permitted and will render the warranty
void.
When operating the device, care must be taken to ensure that the requirements for installation
of a housing in IP20 are also maintained.
Danger!
Any type of operation other than what is described in the instructions places the safety and
functionality of the module and connected systems in question.
