9.1 Fault diagnostics in the electronic insert
!
Note!
In the event of faults during commissioning or operation of the device, you have the ability to carry
out fault diagnostics on the electronic insert. This function is supported by the electronic inserts
FEI51, FEI52, FEI54, FEI55 (see error table 1 and 2 below).
The electronic inserts FEI53, FEI57S and FEI58 signal two types of faults:
• Faults that can be rectified: The red LED flashes.
• Faults that cannot be rectified: The red LED is lit continuously.
For additional information on fault detection and fault elimination, refer to fault table 2 below.
9.1.1 Activating fault diagnostics FEI51, FEI52, FEI54, FEI55
!
Note!
The diagnostics provide information about the operating status of the device. The results of the
diagnostics are displayed by LEDs 1, 2, 4 and 5. If the diagnostics detect multiple faults, these are
shown according to their priority. A serious fault (e.g. priority 3) is always displayed before a less
serious fault (e.g. priority 5).
To activate the fault diagnostics, proceed as follows:
1. Set the function switch to position 1 (operation).
2. Press the "–" key.
3. "Fault table 1" lists possible causes of faults and information on how to eliminate them.

No fault
On Internal fault Replace electronics. 1
On On Calibration point(s) are outside the measuring
range
Recalibrate 2
On On Calibration points have been accidentally
interchanged
Recalibrate 3
On The calibration point is too close to the measuring
range limit.
Reduce the switch point or select a new
mounting location.
4
On On No calibration has yet been carried out. Carry out empty and/or full calibration. 5
On The DC PNP output is overloaded.* Reduce the connected load. 6
On On The capacitance change from probe "covered" to
probe "not covered" is too small.
Contact Endress+Hauser Service. 7
On On Sensor DAT (EEPROM) data are invalid. Carry out download from the electronic insert. 8
On On On Probe is not detected**. The probe type is not compatible. Use a
Solicap S probe.
9
On The measured temperature is outside the
permitted temperature range.
Operate the device only in the specified
temperature range.
10
* Applies only to electronic insert FEI52.
** A connection to the Sensor DAT (EEPROM) could not be established.
Cause Remedy
The device does not switch. Check the connection and the supply voltage.
Alarm LED flashes. The ambient temperature of the electronics is outside the permitted range or the
connection to the probe is interrupted.
