6.5.4 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 pH/redox K1
pH/redox K2
Temperature K1
Temperature K2
Delta
Continous controller
EA2 Caution!
The configuration is
changed.
EA3 0 ... 20mA
4 ... 20mA
EA4 !!Caution!!
Current output 0...20mA
and error current = 2.4 mA
is dangerous.
EA5 linear

INFO
Select a current output
for which the settings apply.
Select 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).
Delta: The difference between the two measuring circuits
will be output at the current output
(circuit 1 – circuit 2).
Continous controller (only at current output 2): The
controller actuating variable is output (see controller
!
menu as well on page 56).
Note!
Danger of data loss. If you change the assignment for the
current output from "continous controller" to a
different function after you have configured the
controllers, the complete controller settings (s. page 56)
is reset to the default values.
Note in display (for changed setting):
Cancel by pressing "PARAM"
Continue (= confirm change) by pressing "E"
Current range selection
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.
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)
Characteristic selection
linear: The characteristic is linear from the lower to the
upper value.
Table: When you do not want the current output charac-
teristic to be linear, you can enter a customer-specific
sequence of up to 10 value pairs in a table. Exact adap-
tation to the non-linear medium behaviour can achieve a
higher level of accuracy.
