SAFETY FUNCTIONS
The safety functions of the OPTBJ board, such as the technical principle and data, wiring examples
and commissioning, will be described in this chapter.
NOTE! The use of STO, SS1 or other safety functions does not itself ensure safety. An overall risk
evaluation is required in order to make sure that the commissioned system is safe. Safety devices
like the OPTBJ board must be correctly incorporated into the entire system. The entire system
must be designed in compliance with all relevant standards within the field of industry.
Standards such as EN12100 Part 1, Part 2, & ISO 14121-1 provide methods for designing safe ma-
chinery and for carrying out a risk assessment.
CAUTION! The information in this manual provides guidance on the use of the
safety functions that OPTBJ option board provides together with VACON
®
100
family control board. This information is in compliance with accepted practice and
regulations at the time of writing. However, the end product/system designer is
responsible for ensuring that the system is safe and in compliance with relevant
regulations.
