Description of errors and corrective actions
Status
type Error message Description Corrective action
F F F F Sensor Sensor Sensor Sensor
Corrupt Sensor Parameter The sensor memory is bad. De-energize and then energize the
device again.
If the message is shown again, tell
the supplier.
No Signal There is no signal from the
antenna or the antenna signal is
too weak for a long time.
Do a check of the device
installation. For more data about
installation, refer to the handbook.
If the message is shown again, tell
the supplier.
Microwave Tuning Voltage Error A microwave error occurred. De-energize and then energize the
device again.
If the message is shown again, tell
the supplier.
Sensor Comm. Error Internal bus communication error
or hardware failure.
No measurement value The converter receives no
measurement data for a long time.
Do a check of the device
installation. For more data about
installation, refer to the handbook.
If the message is shown again, tell
the supplier.
F F F F Electronics Electronics Electronics Electronics
Fatal Converter Error (DM)
1
An electronics or hardware failure
occurred.
De-energize and then energize the
device again.
If the message is shown again, tell
the supplier.
Fatal Converter Error (CO)
2
An electronics or hardware failure
occurred.
Fatal Converter Error (Generic) An electronics or hardware failure
occurred.
CO Safety Reaction
3
Current Output Safety Reaction.
This error message is shown if the
current output is less than 3.6 mA
or more than 21 mA.
Do a check for other error
messages.
Internal Comm. Error Internal bus communication error. De-energize and then energize the
device again.
If the message is shown again, tell
the supplier.
Power Supply Error Internal voltage is too low to
energize the sensor.
Check the electrical connections
to the power supply connection or
replace the converter.
Internal voltage is too high.
Sensor/Conv. FW Mismatch The sensor firmware version does
not agree with the converter
firmware version. This can be
caused by a bad firmware update.
De-energize and then energize the
device again.
If the message is shown again, tell
the supplier.
Max. Number of Restarts The device could not start the
measuring mode after a given
number of times that the device
was de-energized and then
energized again.
Do a check of the power supply.
Inconsistent Parameters Internal bus communication error. De-energize and then energize the
device again.
If the message is shown again, tell
the supplier.
Sensor Comm. Error Internal bus communication error
or hardware failure.
