Cause
The unit is in analogue output or alarm
set point relay simulation mode.
Both analogue inputs are switched off.
Cable open circuit monitor active -
Connection to the sensor is interrupted
on a connection of 4...20 mA, this means
the current is under
3.60 mA.
Below range -
The measured signal connected to the
analogue input is >10% below the valid
measurement range. Is not valid for the
4...20 mA input range.
Over range -
The measured signal connected to the
analogue input is >10% over the valid
" measurement range. Is not valid for the
4...20 mA input range.
Faulty signal monitoring -
On a 4...20 mA input range the signal
connected to the input is outside the
specified range ( >3.60 ...
<3.85 mA or >20.4 ... <21.0 mA)
The measured value calculated from the
two input signals lies below -19999 or
above 99999.
The measured value allocated to the
analogue output is below the -10% value
of the analogue output.

code
E 200 End simulation mode.
E 201 Activate at least one
analogue input.
E 210 Please check the
connection of the
sensor at analogue
input 1
E 220 Please check the
connection of the
sensor at analogue
input 2.
E 210 Please check the
connection of the
sensor at analogue
input 1.
E 220 Please check the
connection of the
sensor at analogue
input 2
E 212 Please check the
connection of the
sensor at analogue
input 1.
E 222 Please check the
connection of the
sensor at analogue
input 2.
E 213 Please check the
function of the sensor
connected to input 1.
E 223 Please check the
function of the sensor
connected to input 2.
E 230 Check if the input
signals are valid, or
check the scaling of
the two analogue
inputs.
Please check if the
input signals are valid
or whether the
calculated values are
within a valid range,
or allocate a smaller
value to the 0% value
of the
E 240 analogue output 1 ,
E 250 analogue output 2.
