5.1.4
Channel switch:
For single sample stream select “None”.
If a second sample stream has been installed, select one of the fol
-
lowing options, depending on your needs:
None:
The switchover between the channels is disabled.
Auto:
Automatic channel switch. The interval can be defined in
menu <Operation>
4.1.31, p. 98
.
User defined:
Channel selection can be defined by the user in
menu <Operation>
4.1.32, p. 98
.
Fieldbus:
Channel switch by fieldbus
5.1.5
Standards:
Enter the concentration of the standard calibration.
5.1.5.1
Standard 1:
Solution 1 (low concentration).
Do not select concentrations lower than 100 ppb
Range: 0.00 ppb–20 ppm
5.1.5.2
Standard 2
: Solution 2 (high concentration).
Select concentration at least 10 times higher than solution 1.
Range: 0.00 ppb–20 ppm
5.2 Signal Outputs
5.2.1and 5.2.2
Signal Output 1 and 2:
Assign process value, the current loop
range and a function to each signal output.
Note:
The navigation in the menu <Signal Output 1> and <Signal
Output 2> is equal. For reason of simplicity only the menu
numbers of Signal Output 1 are used in the following.
5.2.1.1
Parameter:
Assign one of the process values to the signal output.
Available values: Sodium 1 and 2, pH, temperature and sample flow.
5.2.1.2
Current Loop:
Select the current range of the signal output.
Make sure the connected device works with the same current range.
Available ranges: 0–20 mA or 4–20 mA
5.2.1.3
Function:
Define if the signal output is used to transmit a process val
-
ue or to drive a control unit. Available functions are:
Linear, bilinear or logarithmic for process values.
See
As process values, p. 100
.
Control upwards or control downwards for controllers.
