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.
Frequency range (Hz) Continuous Intermittent
10 ≤ f ≤ 58 Amplitude = 0.0375 mm Amplitude = 0.075 mm
58 ≤ f ≤ 150 Constant acceleration = 0.5 g Constant acceleration = 1 g
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.
