6.4.4 Set up 1 – Current outputs
The transmitter is equipped with two current outputs.
To enter the menu, proceed as follows:
CODE CHOICE
(default = bold)
E1 Current output 1
Current output 2
Current output 1 (or 2):
EA1 PV input 1
PV input 2
Temperature input 1
Temperature input 2
Characteristic value
Continuous controller
(only at current output 2)
EA2 !!Caution!!
The configuration is
changed.
EA3 0 ... 20mA
4 ... 20 mA
EA4 !!Caution!!
Current output 0...20mA
and error current = 2.4 mA
leads to uncontrolled
behaviour.
EA5 Linear
Logarithmic
⇒
INFO
Select a current output
for which the settings apply.
Select the measured value,
which should be output at the current output.
Selection possibilities related to the instrument variant
and the selected output (see selection table
above).
PV 1/2 (=primary value): Selection of the primary
measured value which you selected, (conduct., conc.,
resist.)
Temperature 1/2: Selection of the temperature to be
output to the current output.
Related (only for related circuits): The characteristic
value from Field A3 is output at the current output.
Continuous controller (only at current output 2!): The
controller actuating variable is output via the current
!
output (see also Controller menu page 54).
Note!
Danger of data loss. If you change the assignment for
the current output from "continuous controller" to a
different function after you have configured the
controllers, the entire controller configuration
(s. page 54) is reset to the default values.
Note in display (for changed setting):
Cancel by pressing "PARAM"
Continue (= confirm change) by pressing "E"
Select current range
Note in display:
Error current is in the measuring current range. When
the current range is "0 ... 20 mA" and "Min" is selected
under Alarm in Field H1, (see page 44).
Recommended combinations:
Current range 0...20 mA and error current max (22 mA)
or
Current range 4...20 mA and error current min (2.4 mA)
Select the characteristic
Linear: The characteristic is linear from the lower to the
upper value.
Logarithmic The characteristic is logarithmic from the
lower to the upper value.
