Diagnostic functions of the PM-E F pp DC24V PROFIsafe
Behavior in Case of Supply Voltage Failure
The failure of the PM-E F pp DC24V PROFIsafe power supply is always indicated by the
PWR LED on the module (light off). This information is also provided in the module
(diagnostic entry). The relay output of the module is passivated.
In the case of a voltage dip in the external auxiliary voltage, the SF LED lights up, the
module is passivated.
With the subsequent supply recovery (level must remain above the specified value for at
least 1 minute (refer to the technical specifications: voltages, currents, electrical potentials))
the SF LED goes out again, the module remains passivated. The SF LED flashes if there are
no other errors, until the error is acknowledged.
