Fault Meaning
code
307 Possible causes:
H
• The internal sensor supply is short-
circuited to ground.
• Impermissibly high electromagnetic
interference is present.
30D F-source address placed in the electronic
H
coding element and F-destination address
cannot be accessed.
30E No valid PROFIsafe address is stored in the
H
retentive memory. Possible causes:
• Initial commissioning
• Deliberate parameter change of the
PROFIsafe address
• Deviation between setpoint and actual
configuration of the plant
310 Too many signal changes have occurred
H
within the time configured with the
"Monitoring window" parameter.
• The "Monitoring window" parameter
setting is too high.
• The "Number of signal changes"
parameter setting is too low.
• A momentary interruption/short-
circuit of the sensor cable (loose
contact) is present.
• Impermissibly high electromagnetic
interference is present.
• The sensor/switch is bouncing.
• The sensor is defective.
311 The switching frequency of the sensor is
H
too high.
312 The minimum permissible temperature
H
limit has been violated.
314 The discrepancy time set for 1oo2
H
evaluation was exceeded.
The error message is output for channel
n+4.

Remedy
• Eliminate the overload.
• Eliminate the short-circuit in the
process wiring.
• Check the "Sensor supply"
parameter.
• Eliminate/reduce the
electromagnetic interference.
Check whether the coding element is
available. Replace the coding element,
if necessary.
• Perform the assignment of the
PROFIsafe address during initial
commissioning or deliberate
parameter changes.
• Check the consistency between the
setpoint and actual configuration.
• Check the "Monitoring window"
parameter.
• Check the "Number of signal
changes" parameter.
• Check the process wiring.
• Eliminate/reduce the
electromagnetic interference.
• Replace the sensor.
Reduce the switching frequency of the
sensor.
Operate the F-module within the
specified temperature range. (See
Technical specifications (Page 65))
