message

Cause Cure
E 090 Loop current too low. To store
operating data a mimimum of
3.6 mA has to be provided on
the input. Check loop circuit.
E 101 The hardware required to store
the operating parameters is
defective. Please exchange the unit.
E 102 Checksum of operating
parameters is invalid or the
software version does not
correspond with the operating
data. Possible cause is a
power failure during a
parameter save procedure. A PRESET is automatically initiated
by operating the "E" push button. This
means that all parameters are
returned to the factory default values.
Any special customer specific
settings made at the factory are not
taken into consideration!
E 103 The calibration values for the
analogue input are faulty.
Possible cause is a power
failure during calibration, an
uncalibrated unit or a defective
unit. Please exchange the unit.
E 106 Warning: Due to an installation
fault an incorrect setting up of
the display range/scale was
made (lower and upper values
are identical). Please correct the values.
E 111 The hardware for saving the
operating parameters is
defective. Please exchange the unit.
