Safety-related information
2.6 Interface to other devices
The integration of the MultiControl into a conveyor system can create additional potential hazards. Such potential
hazards are not covered by this operating manual and must be analysed during the development, installation and
commissioning of the conveyor system as a whole.
¾
Following the integration of the MultiControl into a conveyor system, the entire system must be checked for any
new potential hazards that may be present before the conveyor is switched on.
2.7 Functional safety
Information on the performance level according to DIN EN ISO 13849-1: 2015
The statistical analysis of the MultiControl AI / BI according to the „Part Counts Method” has led to the following result
if the maximum permissible ambient temperature of 40 °C is observed:
MTTF (h) :
812691 Hours
MTTF (a):
93 Years
Provided that the behavior of the MultiControl is changed in the event of system-relevant errors in the “Error
Handling Settings” of the MultiControl user interface, this results in an achievable performance level of “C” (see
„Error Handling Settings“ on page 45).

In order to fulfill a safety function, the safety-related disconnection of the load voltage (motor voltage) is also
required.
