Diagnostic message
Supply voltage too low
F-module error (0x032F)
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.
With subsequent voltage recovery (level must be within the specified value range for at least
1 minute (see Technical specifications (Page 65): Voltages, Currents, Potentials)), the DIAG
LED stops flashing. The module remains passivated.
Behavior in case of cross circuit/short-circuit to the sensor supply
When internal sensor supply is configured and short-circuit test is deactivated, short-circuits
to ground at the sensor supplies are detected. Channels for which the relevant sensor supply
is configured will be passivated.
When internal sensor supply is configured and short-circuit test is enabled, short-circuits to
ground and potential at the sensor supply are detected. Channels for which the relevant
sensor supply is configured will be passivated.
Special features for fault detection
The detection of certain faults (short-circuits or discrepancy errors, for example) depends on
the application, the wiring, and the parameter assignment of the short-circuit test and the
sensor power supply. The corresponding tables for error detection can therefore be found in
the applications under Applications of the F-I/O module (Page 37).
Generally applicable information on diagnostics
For information on diagnostics which apply to all F-modules (e.g. reading out the diagnostic
functions, passivation of channels), refer to the SIMATIC Safety - Configuring and
Programming (https://support.industry.siemens.com/cs/ww/en/view/54110126) manual.

322 Possible causes:
H
• The supply voltage is too low.
• Incorrect BaseUnit
32F Possible causes:
H
• Impermissibly high electromagnetic
interference is present.
• The F-module is defective.
• Check the supply voltage.
• Use a BaseUnit of Type A0.
• The internal diagnostics has
detected an error. Removing and
inserting the module or POWER OFF
– POWER ON necessary.
• If the F-module cannot be put into
operation anymore, consider a
replacement.
