9.1.2 Fault diagnostics FEI53, FEI57S
Cause
The device does not switch.
Alarm LED flashes.
9.1.3 Activating fault diagnostics FEI58
Displaying the diagnostic code
This function makes it possible to interpret faults using the three LEDs. If the system has
detected more than one fault, the fault with the highest priority is shown on the display.
To display the diagnostic code, proceed as follows:
1. Press the B key for at least 2 s.
2. The current diagnostics code is indicated by the LEDs (operating/fault/switching
status).
Cause
No fault
Internal fault
The calibration point is too close to the
measuring range limit
Calibration points have been accidentally
interchanged
No calibration has yet been carried out
The change in capacitance from uncovered
probe to
covered probe is too small
Probe not detected
The measured temperature is outside
the permitted range

Remedy
Check the connection and the supply voltage.
The ambient temperature of the electronics is outside the permitted range
or the connection to the probe is interrupted.
Remedy
- - -
The device is defective
Reduce the switch point or select a new installation
location
Perform uncovered calibration with the probe
uncovered, and covered calibration with the probe
covered
Carry out empty and/or full calibration
The capacitance change between the uncovered and
covered probe must be greater than 2 pF
Connect the probe
The device may be operated in the specified
temperature range only
