setting
* Output range
RANG
selection of current or
voltage output with
indication of 0% and
100% values
4-20mA, 0-20mA, 0-10V
4-20
* Scale
Analogue output 0%
OUTLO
Allocation of numeric
display value to the 0%
analogue output value.
Selection range:
Display value 0% (
DILO )to
Display value100% (
DIHI )
0.0
* Scale
Analogue output 100%
OUTHI
Allocation of numeric
display value to the 100%
analogue output value.
Selection range:
Display value 0% (
DILO )to
Display value 100% (
DIHI )
100
* Fault condition
FAIL
Definition of the output
signal in fault condition.
These are cable open
circuit or unit internal fault.
HOLD Output of last
valid measurement
MIN Output 0% value,
at 4-20mA: 3.6mA
MAX Output 100% value,
at 4-20mA: 21mA
HOLD
* Simulation
voltage/current
SIMU
Dependent whether
current or voltage output
is set, a number of values
are offered that can be
transmitted to the output.
OFF Simulation is switched
off, the output value is
proportional to the
measured value.
Voltage output:
0,0V , 5,0V , 10,0V
Current output:
0,0MA , 3,6MA , 4,0MA , 10,0MA ,
12,0MA , 20,0MA , 21,0MA
OFF
Once this address is left the output is automatically set to OFF .
The red LED flashes during active simulation!
OUTPT
For inverted signal output the 100% value must be smaller than the 0%
