Mechanical environmental conditions
The mechanical environmental conditions for the operation of fail-safe signal modules are
defined in the table below based on sinusoidal vibration.
Reducing vibration
Suitable measures must be taken to reduce acceleration and amplitude at locations where
the fail-safe signal modules are exposed to greater shock or vibration.
It is advisable to install the modules on a damping material such as rubber-to-metal vibration
dampers.
Test of mechanical environmental conditions
The table defines the type and scope of testing mechanical environmental conditions.
