Manual, 08/2018, A5E41448857-AB
Supply voltage outside the nominal range
If the supply voltage L+ is outside the specified value range, the DIAG LED flashes and the
module is passivated.
When the voltage is then recovered (level must remain within the specified value for at least
1 minute (see Technical specifications (Page 64): Voltages, Currents, Potentials)), the DIAG
LED stops flashing. The module remains passivated.
Generally applicable information on diagnostics
Information on diagnostics that pertains to all fail-safe modules (for example, readout of
diagnostics functions or passivation of channels) is available in the SIMATIC Safety –
