Solution
On Flash The 7
segment
display
shows a text
The unit is in analogue output or alarm
set point relay simulation mode.
E 200 End simulation mode.
Display
shows:
“
E 201”
Both analogue inputs are switched off. E 201 Activate at least one
analogue input.
A measured
value or
“
NNNNN”is
shown in the
display
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.
E 210
E 220
Please check the
connection of the
sensor at analogue
input 1
Please check the
connection of the
sensor at analogue
input 2.
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.
E 210
E 220
Please check the
connection of the
sensor at analogue
input 1.
Please check the
connection of the
sensor at analogue
input 2
The display
shows a
meas. value
or “
UUUUU”
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.
E 212
E 222
Please check the
connection of the
sensor at analogue
input 1.
Please check the
connection of the
sensor at analogue
input 2.
A meas.
Value or
“
-----”is
shown in the
display
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)
E 213
E 223
Please check the
function of the sensor
connected to input 1.
Please check the
function of the sensor
connected to input 2.
The 7
segment
display
shows a
meas. value
The measured value calculated from the
two input signals lies below -19999 or
above 99999.
E 230 Check if the input
signals are valid, or
check the scaling of
the two analogue
inputs.
The 7
segment
display
shows a
meas. value
The measured value allocated to the
analogue output is below the -10% value
of the analogue output.
E 240
E 250
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
analogue output 1 ,
analogue output 2.
